Air Source Heat Pump Reviews

Heat pumps are an increasingly popular and common heating solution for homes and businesses. But what do those who have taken the plunge have to say about them?

air source heating reviews uk

Just a few years back, air source heat pumps weren’t all that common. In 2021, it was reported that 74% of England and Wales households rely on traditional gas heating, which accounts for a lack of awareness of heat pump technology.

But, with the growing focus on carbon emissions, the increase in energy costs and the ban on installing gas and oil boilers in new builds in the coming years, air source heat pumps are increasing in popularity.

Before we take a look at what customers have to say about their new air source heat pump, let’s take a brief look at how they work and the benefits over a traditional LPG, oil or gas boiler.

How do air source heat pumps work?

Air source heat pumps deliver heat and hot water to properties by extracting energy from the outside air. The electric-powered unit turns the heat energy into a liquid and passes it through a compressor. It’s then delivered via hot water circuits (i.e. your existing central heating system pipework) to provide heating and hot water.

Note that this refers specifically to air-to-water heat pumps. Air-to-air heat pumps are also available but are generally used to provide warmth rather than to heat water.

This is very much the short story! For a more in-depth look at how they work, please see our air source heat pumps FAQs page.

Air Source Heat Pumps are Environmentally Friendly

Air source heat pumps are powered by electricity and harness the energy of the outside air to heat your home via a wet central heating system or underfloor heating. Crucially, unlike a conventional gas or oil boiler, a heat pump does not use fossil fuels, so it drastically reduces the carbon footprint of your property.

The ‘magic’ of air source heat pumps is that you get far more energy out (in heat) than you put in (in electricity). For example, an average air source heat pump returns a SCOP (Seasonal Coefficient Of Performance) of between 3-4. This means that, on average, the heat pump will produce between 3-4kW of heat energy from 1kW of electrical energy.

When combined with solar panels, air-source heat pumps become an even more environmentally friendly option, contributing to a greener and more sustainable future for us all.

Air Source Heat Pumps Heat and Cool Your House

An air source heat pump is a versatile system that not only provides heating but can actually cool your home in warmer months. Working on the same principles of heat transfer, during warm weather, they reverse the process to remove warm air from your home, to create a comfortable and cool environment.

It is however worth noting that delivering cooling via and air to water heat pump get complicated when retrofitting onto an existing system (with radiators for example).

Air Source Heat Pumps Save money on your energy bills

Depending on your current energy tariff, installing an air source heat pump could reduce your heating energy bills. By harnessing the latent warmth in the air, a heat pump requires less energy to generate the same level of heating, resulting in reduced energy consumption and a lower annual fuel bill.

Typically, the largest savings are seen when replacing electric storage heaters and old oil, LPG and natural gas boilers. Air source heat pumps have minimal maintenance requirements, so also represent a saving when it comes to running costs.

The Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme (BUS) is designed to help households make the switch to more energy-efficient heating systems by providing them with a grant towards the installation of a heat pump. Eligible households can receive a voucher of up to £7,500 to help cover the cost of installing an air source heat pump, or up to £6,000 for the installation of a ground source heat pump.

It’s important to note that eligibility for the BUS grant is not based on means testing, but rather on your energy performance certificate (EPC). The EPC provides an assessment of your home’s current energy efficiency level, and a rating of A to G is assigned based on this assessment. In order to be eligible for the BUS grant, your home must have an EPC rating of D or lower.

If you are eligible, an MCS-certified installer like Cinergi will apply for a voucher on your behalf. 

What are the downsides of an air source heat pump?

In the interest of presenting a two-sided story, let’s run through a few common reasons that people are hesitant when it comes to installing air source heat pumps.

  • More Expensive to install – Compared to a traditional gas boiler, the upfront cost of purchasing and installing an air source heat pump, including any necessary modifications to heating systems and the installation of a hot water cylinder, can be relatively high.
  • Space requirements – Heat pumps measure around 0.5-1 metre wide, so may not be suitable for properties with limited outdoor space.

As with all home investments, it’s important to get the advice of a qualified and registered installer to weigh up the benefits of installing a heat pump in your home or business.

Just a fantastic job, I would highly recommend Cinergi for your heat pump. The team are highly knowledgeable and willing to help with any questions before and after the job was completed.
Paul C.
WOW, what a company! As far as exceptional customer service, Cinergi absolutely wipe the floor with other businesses and trades we have engaged with over the years. They manage to deliver big company service and performance, with the interaction and expertise of a family run unit - what more could you want when you're making changes to your home.We engaged Cinergi to fit an air source heat pump (10kw Valiant), a hot water tank, and radiators throughout, which included towel radiators as well - as there were none in the property when we purchased. There was no mains gas piped to the house, which was a key indicator for us making the move to ASHP, and we were thankfully eligible for the UK Government grant - which Cinergi were able to assist us with.From the very first phone call with Megan, to the site visit (before we had the keys) with Elliot (to work out the size of our heat pump and water tank as well as there placement at the property), then Ian to make sure the radiators were appropriate for the spaces (when we were in), the team were incredible with our pre-installation support. Not forgetting all of the hard work Steph and Kate did in this, being flexible and accommodating for our circumstances (delayed completion of our property).The star of the experience has to be called out though, Lewis (the main engineer on site) worked professionally and courteously with all of the other trades (electricians, roofers, etc.) day in and day out. He provided a clean safe environment every day, being conscious of those around him, helping trades out to be as efficient as they could be too. The level of craftsmanship in his work is an art form (see the photograph of the water tank). He had help on some days, Tommy and Adam, Lewis L and another person (name escapes me right now), but Lewis managed all of that, and helped to keep me sane through the renovation work - a true testament to professional tradesman who truly care for the work they do, and a massive asset to Cinergi...all of the team are.You'll note I can name everyone in the process; big company, family feel! It never felt too much, we never felt overwhelmed. If you need heating, hot water or any other work in their portfolio (Solar, Batteries, EV chargers, etc.), don't look anywhere else - you will not be disappointed with the products or services Cinergi offer. 100% we would recommend.
Liz C.
I'm so pleased with the work Cinergi carried out for us. We had solar panels, a Tesla Powerwall and a EV Charger installed. Excellent and personalised customer service, helpful design, high quality workmanship and follow-up. Every member of their small local team was dedicated and helpful in every way. I highly recommend them.
Nicola E.
Very pleased with our heat pump installation. From our first meeting seeking information through to the actual installation we found the team friendly and knowledgeable. Charlie did an excellent job of integrating the new system with our complicated existing system. We are enjoying having lots of hot water now and looking forward to having a warm house when autumn arrives.
David F.
Great team, the lads were friendly and polite, turned up when they said they would. Fitted Solar panels and Teslar Powerwall battery quickly with out an disruption, left the place cleaner than when they arrived. Happy top recommend.
Matthew B.
Great customer service, couldn't have done more.We went with Cinergi to install our Air Source Heat Pump, rather than one of the big installers, this was primarily so that we knew the people doing the installation, and their was continuity throughout.We had a few technical/supply issues with the install, none of which were down to Cinergi, they didn't stop working though and were determined to find the resolution, including some long late days and weekends to get us up and running as quickly as possible.Would be happy to recommend Cinergi to anyone looking to install an Air Source Heat Pump

You dream that companies like this still exist. Excellent caring service from the first moment. Honestly look no further i cannot recommend them highly enough.
João E.
I commissioned Cinergi to install a Vaillant aroTherm air source heat pump 1 year ago, and it has been great. Not one problem. The installation was done very quickly, and Dan and Adam did a fantastic job. I could not recommend Cinergi more. Very professional during the tender process, the flexibility on the scheduling, and the actual installation, finished in advance of the scheduled time. Thank you very much!!
Dan M.
Jade S.
We contacted Cinergi for an additional Tesla battery install after our initial install in 2023. A great service provided and very efficient. Would highly recommend!
Response from the owner: Hi Jade,Thank you for leaving such a positive review. We're so glad to hear that you are happy with your Tesla Powerwall. Our engineers take pride in their work and will be very pleased to hear that you were impressed by the installation.

Rob P.
I commissioned Cinergi to install an Air Source system and PV panels coupled with Tesla Powerwall. From my initial meeting with Dan until the systems were handed over the Cinergi team were pro active throughout. I have delayed submitting a review until we had seen both through the winter (the installation was completed just before Christmas). Our home has been perfectly warm throughout and we are now generating good levels of electricity from the Solaredge PV system.I am very happy to recommend Cinergi and would willingly speak with anyone thinking of installing.Rob P

Amy W.
Cinergi are fantastic. A plumber recommended them and I will do the same going forward. They gave me all the time I needed to ask questions, never missed out any information, they assured me they could get the ASHP tank in my loft (British Gas refused) and the guys that did the installation were so polite and hardworking, always cleaned up after themselves, didn't take the easy route and didn't leave until the job was done. Took away all the materials from my old system, a roofer popped round to refix a tile they needed to remove for the flue, they gave me electric heaters for the days when I was without heating and generally made a fantastic job of plumbing throughout. The paperwork is extremely thorough and efficient. I got the government grant immediately and so far I'm incredibly smug and happy about the fact that I am not heating my home by burning gas, and that old gas boiler (with inevitable toxins) is now out of my sons bedroom! If they tell you you can have an Air Source Heat Pump - have it!
Response from the owner: Hi Amy, Thank you for taking the time to leave such a detailed and positive review. We're so delighted to hear that you had a great installation experience - our engineers are glowing from your feedback. We do find that there's a certain 'smug' factor after switching to an Air Source Heat Pump😉 If there's anything else we can do to help, please do feel free to get in touch. Thank you again. Kindest regards,Team Cinergi
Maggie H.
Highly recommend these guys. Professional, helpful and hugely accommodating. Big thanks to Charlie who was a star. Below picture of install inside airing cupboard. Every single one of those pipes are 100% plumb!
Response from the owner: Hi Maggie, Thank you for your kind review. We're delighted to hear that you had a positive installation experience - we'll pass your feedback on to Charlie! If there's anything else our team can support you with, please do let us know. Best wishes,Team Cinergi
Adrian C.
We have been so impressed with every contact with Cinergi, from the initial discussions about our options for an Air Source Heat Pump, to the communication and speed of response during the contract negotiations.Their customer service is some of the best I have seen for many years, everyone that you speak is courteous, helpful and quick to respond.The installation too was undertaken in a professional way and the standard of workmanship is very high. We are very pleased with our new system and will hopefully be using Cinergi again for a battery storage system. Highly recommended.
Response from the owner: Hi Adrian, Thank you for writing such a kind and detailed review. It's an absolute pleasure to hear that you were impressed by our customer service and workmanship. If there's anything else we can assist you with, please don't hesitate to be in touch. We're looking forward to working with you again in the future. Kindest regards,Team Cinergi

Great install from local firm. Friendly installers. Good answers to questions. Sensible advice. Helpful handover of equipment and follow up from office
Response from the owner: Hi Evan,Thank you for taking the time to leave us a review. We're glad to hear that our team were able to provide you with a positive experience. If there's anything else we can do to help, please do get in touch. Best wishes,Team Cinergi
Philip L.
I selected Cinergi from 3 possible suppliers who had submitted a quotation for the supply and installation of a heat pump and battery system. Before taking the final decision to invest the company already impressed me with their responsiveness and ease of engagement. The team took the time to answer all my questions even if that meant ploughing through a long email. A lot of thought went into selection of the right ASHP which included picking the vendor, not just the size of the pump. We are pleased with the Vaillant user interface. I’m looking forward though to being able to download more operational data to help me understand and optimise the running of the system.The installation team was led by a very competent and personable plumber. He kept us well informed about progress and the challenges he had to address along the way. He was very approachable and exuded knowledge so never felt out on a limb regarding the installation. The components for the ASHP system have been neatly spaced out in the attic and outside and work ethics were good: attention to safety and tidiness all along.A few weeks into running the new system we flagged that the biggest radiator took too long to heat up. Cinergi arranged for the plumber to come back within a couple of days and he addressed the problem by rebalancing the radiator system and tweak the setting of the circulation pump. We took the opportunity to learn from him about other operational matters.I greatly recommend the company for your heat pump project.
Response from the owner: Hi Philip,Thank you for taking the time to leave such a detailed review - we greatly appreciate your feedback. Making sure our customers are cosy and satisfied with their heat pumps is our top priority, so we're glad to hear that your system is working well after a few tweaks. If there's anything else we can do to support you, please do let us know. Kindest regards,Team Cinergi
Andrew L.
I’m building a new house and need a heat pump, solar and battery. Cinergi are the only Company where the person you speak to (Meghan) organises a Director to call back when there’s a highly technical query. Ian certainly knows his stuff and it’s easy to see why they have so many 5* Reviews.
Response from the owner: Hi Andrew,Thank you so much for taking the time to leave a review. We're fortunate to have a close-knit company where specialised expertise is always on hand! If there's anything else we can support you with, please don't hesitate to be in touch. Kindest regards,Team Cinergi
David D.
Cinergi were recommended by my Vaillant Heat Pump supplier. They offer an annual service plan, and responded helpfully and professionally to a recent problem. Easy to communicate with too. I can highly recommend this Company.
Response from the owner: Hi David,Thank you for your kind recommendation. We're so glad to hear that you found our service professional and helpful. If there's anything else we can do to assist you, please do be in touch. Kindest regards,Team Cinergi
Hugh C.
Excellent heat pump and underfloor heating installation from start to finish. Easy heat loss assessment and quoting process. Clear, friendly and prompt communication from the office staff. Conscientious installation team. The system is working as it should and meeting expectations on COP. Good liaison with the subcontractor doing the underfloor heating. One slight problem when the hot water tank didn’t fit the space but this was apologised for and rectified. Price was in line with other quotes. Highly recommended!
Response from the owner: Hi Hugh, Thank you for your kind review. It's a pleasure to know that you had a positive installation experience and that your systems is meeting your needs. If there's anything else we can assist with, please don't hesitate to be in touch. Best wishes, Team Cinergi
Stephen T.
Just had a Heatrae Sadie and a Sunamp Thermino fitted by Cynergy Ltd Romsey. The installation was carried out by Adam (heating engineer) Dan and Josh (electricians). They were all very professional and nothing was too much effort.All in all from first discussion with Ian to the end of installation has been an excellent experience.Steve,The Malthouse, Romsey
Response from the owner: Hi Stephen, Thank you for your review. It's always a delight to hear that you had a positive experience from installation to after care. Please feel free to be in touch at anytime if there's anything we can help you with. Kindest regards,Team Cinergi
Paul W.
We had Dan come and inspect our property in order to give us a quote for a new air source heat pump. Waited a week and no quote so contacted Cinergy. 2 weeks later still no quote. Finally got quote when I left a poor review.
Response from the owner: Hi Paul, we hope you and the family are well 🙂 I've taken a look into what happened here and can confirm that the quote was sent to your e-mail address 2 weeks prior to you leaving the above review (1 week after surveying your property). Although we do aim to get our proposals quicker than this, some of the team were on annual leave this week, for which I do apologise. When we got notification of your review, 2 weeks later, we resent your proposal to both e-mail addresses we have on our system for yourself, and called to ensure you received them.I can only assume that your original proposal found its way into your junk founder, and I do apologise for any inconvenience caused.As always, please do get in touch if we can help you in any way :)The Cinergi Team
Nicola B.
Cinergi are amazing, incredibly respectful and very tidy plus the aftercare is second to none. I would highly recommend!
Response from the owner: Hi Nicola, Thank you so much for your review. Respect is one of our core company values and it's of the upmost importance to us that each of our customers feel respected and supported. Please don't hesitate to be in touch if there's anything else we can assist you with. Best wishes, Team Cinergi
Juliet W.
Cinergi have been fantastic with our job from start to finish. All of their employees (we met 6 in total) were polite, helpful, tidy and a pleasure to have around both inside and outside of our home. They answered our daft queries without difficulty, made helpful suggestions and ensured we understood the system they had installed. I wouldn’t hesitate to recommend them.
Response from the owner: Hi Juliet, Thank you for taking the time to leave such a positive review. We were delighted to assist you with your queries and please don't worry, no question is a daft question! Thank you for your kind recommendation. Please don't hesitate to be in touch if there's anything else we can assist you with. Warm regards,Team Cinergi
Chris Z.
Thanks to everyone at Cinergi on a great job - we couldn't be happier with the solar generation system and the staff were helpful, transparent, friendly and knowledgeable at all stages. We'd happily recommend Cinergi to friends and will be in touch in the future to install an Air Source Heat Pump
Response from the owner: Hi Chris, Thank you so much for your kind review. We're delighted to hear that you're happy with your solar panel system and that you found our staff to be helpful and knowledgeable across all stages. Thank you for your kind recommendation. We will certainly be available to assist should you choose to install an Air Source Heat Pump in the future. Best wishes
Paul H.
It is the second time I have used Cinergi once for an air source heat pump and recently for solar panels and a battery installation. I have been very pleased on both occasions with the standard of work proffesionlism and after care that the company give, I would not hesitate to reccommend them.
Jonathan P.
I was initially hesitant to know where to go when upgrading to a Heat pump in a large Edwardian detached house. I had no need to be concerned.Cinergi guided me few the few hurdles from start to finish. They also handled the Heat pump grant for me.The system was installed in the Autumn of 2022 and the bills plummeted, assisted by solar panels and having batteries.i can't thank them enough and have been very happy and more importantly toasty warm with the Vaillant system.Jonathan Perry (Bournemouth)
Peter S.
Overall a positive experience. The system has been up and running now for around 6 months and had no issues keeping the house warm in the winter. I found the Cinergi team to be always friendly and helpful. When small issues did arise during the installation process and thereafter they were always responsive and helpful in dealing with them. Would recommend.
David B.
Delighted with the team’s expertise and knowledge fitting our Daikin heat pump in December 2021. Works very effectively and suited our space and existing pipework very well. Excellent service and follow up maintenance too.
Paul E.
Cinergi installed a new ASHP, and did so professionally, with excellent communications and were a pleasure to work with - I would recommend them and would use them again.
Abby B.
Professional service and great aftercare, we had an issue with our unit ( not Cinergi’s fault) and they can out and resolved promptly which was great. Very knowledgable about the system and made helpful suggestions to get it working as required with other elements outside of their control.
Mark F.
A professional company who were friendly and supportive from the first enquiry until completion of the installation. They offered good advice and were very adaptable in working with me on our install design and timescales as we were doing a renovation at the same time. I have no hesitation in recommending them.
david R.
Cinergy are the first company that I have ever felt safe to recommend to friends. Their installation of a high temperature air source heat pump system, replacing our smelly old oil boiler was brilliant.
Daniel G.
I had a heat pump, battery and solar panels installed through Cinergi and would 100% recommend. High quality, professional work and great, friendly customer support.This scale is installation into an older property was never going to be without complication but they were brilliant throughout, going the extra mile to bring it all together.
Andy P.
In April 2022 Cinergi fitted an ASHP to our house and removed the gas boiler. I reviewed this on Trustpilot in May 2022 but forgot to do the same here. Below is my Trustpilot review, followed by a few comments made one year later.************************Installation of ASHP in place of gas boilerEarlier this year my wife and I contacted Cinergi with various questions concerning the viability of replacing our gas boiler with an ASHP. The outcome was that in April they installed a Vaillant Split air source heat pump, which seems to be exactly what we were looking for. Overall, we're very pleased indeed with the whole process - from the initial discussions, survey and installation, through to arranging for all relevant certificates, guarantees etc to be sent to us.The Cinergi team listened carefully to us, addressed our concerns, advised us on the placement of the outside unit and took great care in fitting the inside unit, tanks, pipes etc into our small utility room – a work of art!When required, the thing enthusiastically heats up our water tank and no doubt won't make any fuss about keeping our house warm through the winter months.Happy days!*******************************It's now June 2023. Our ASHP has supplied us with hot water and heating for just over 12 months, including unusually cold winter weather, without any fuss or bother at all. It's lived up to our hopes and expectations. The weather over any two years is never exactly the same, but during the 12 months after the ASHP's installation the energy supplied to our house (all electricity) was exactly 40% of that supplied (both gas and electricity) during the 12 months before its installation – ie our energy intake has fallen by 60%.We're now back in touch with Cinergi in order to add some more PV cells.
paul H.
Did the job very well and exactly as scheduled, expertly with no inconvenience. Would recommend this company as opposed to the other companies I contacted to do the installation. Support since installation has been good. The system has worked well.
Ayjay E.
Cinergi were a joy all the way from quote through installation of the heat pump and on to annual servicing. They have been prompt and efficient throughout and nothing is too much trouble.Other companies who quoted did not take enough time or care to consider what needs or requirements this particular house had and so their recommended solutions did not take into account levels of insulation, use and occupation of the house or even practicalities. Cinergi took the time to explore the house properly and were even willing to come up with solutions to upgrade the radiators without having to move the giant sofa! a really good service and I am delighted with my heat pump. It is the perfect solution for rural homes who are not on the gas grid and Cinergi are the perfect team to do the job!
Patrick
I would highly recommend Cinergi if you’re considering purchasing an ASHP.I carried out lots of research on the web to try to find the best equipment to use and how it would all work in our home, I found it quite complicated especially trying to figure out the size of equipment required.I contacted several companies for an initial consultation and quote. Dan from Cinergi visited my property and carried out a full assessment of what was required to heat our house and supply hot water. His knowledge was superb, he explained what would be required and how the whole system would work, he answered all my questions including many concerns I had about changing form a traditional Combi boiler to ASHP.I went ahead with Cinergi to install our ASHP system. Ian lead the install team his knowledge was phenomenal, he recommended a few small adjustments which fully optimized the system.All the equipment and materials used on the project were of high quality, the installers were clean tidy and very respectfully. We were extremely happy with the end result and the functionality of the system; our electricity bills have dramatically reduced since installing the system.I dealt with the main office to organise the installation of the ASHP and get all certifications.Kate & Daisy have been extremely helpfully, they really go out of their way to make sure to make sure the customer is happy.Overall a great company, extremely knowledgably with a highly skilled installation team and great customer service
david W.
My boiler required replacement and I was considering replacing it with an ASHP. I did not know anyone with one of these so researched the net and approached various companies for advice and cost. I chose Cinergi as they provided excellent advice regarding using some of my existing system and offered components with good on-line reviews. Dealing with them was easy, they were responsive and flexible and commenced the installation earlier than we initially agreed. Their installers were polite, clean, tidy, professional, knowledgeable and very nice to chat with. Don't worry about the noise of an ASHP, I could not tell the heat pump was operating over the noise of a hoover a street away! The water pump remains the noisiest part of the system.Now 6 months on I am through the system's first winter. My electricity bills have been were much less than I have seen on the news. In really cold weather, occasionally I needed to use the gas fire in the living room, but the house was generally a comfortable temperature. The system still seems to be operating as it should and now we have moved into summer the heat exchanger makes a useful side table on the patio! Very happy that the company seems to contact customers on a regular basis.
andy F.
Highly recommend Cinergi for all things renewable. They installed a heat pump with solar to our new build and were a pleasure to deal with. Always contactable and accommodating to timescale demands when building our property. Don't look anywhere else !
Tom L.
Cinergi replaced our gas central heating with an ASHP in Feb 2022. The process from the assessment to the comissioning was exceptionality smooth.We've been living with the system for over a year and had zero issues with it.We're on their yearly service plan which is also excellent. The team are great, providing an excellent overall service.
Chris R.
All staff are very polite and helpful. Heat pump works fairly well. It will be due a service soon and will give an opportunity to make a few adjustments. One major problem is the Heatmiser Control.It allows temperature to drop at least one degree below setting before starting again. From work at university I know this is very inefficient. For heat pumps to compete with Gas boilers they must match the simple technology of a dial to set temperature and the simple advance button to instantly switch on heating.

Project 1, Installation of Air Source Heat Pump & Removal of old gas boilerProject 2, Installation of Solar PV System: -The company is a very well run and organised family business, demonstrated by the ethos emanating from all.From first Web site impression (Everything, well explained), Enquiry, Survey, Tender, Clarifications, Contract, Installation, Commissioning ….. to Handover Documentation, the Team performed exceedingly well and beyond client expectation.For a time, Solar PV project ran in parallel at the same site location as ASHP installation.Onsite personal, always worked well as a team, helping each other in their areas when required (no demarcation issues, no subcontractors, just one company).Communication with the client was always respectful and courteous, taking time to explain any answers to questions that were put their way. Installation wasn’t rushed but well thought through and agreed with client, must give a special thank you to Justin Parry, whom performed exceptionally well throughout the ASHP project.Water is hot and plenty of it too, central heating system is working well and of course will be tested fully this coming winter 😊Good liaison was had with client for Solar PV install, including the battery of which needed further consideration with respect to installation location and its service access panel.Solar Edge, delayed final live commissioning, due to a software update preventing client app monitoring of the system. Cinergi Ltd worked hard to resolve SolarEdge’s problem and kept client informed and updated.Glad to say, the Solar PV system is working very well and can be monitored on the Solar Edge app.Thank you !!!Cinergi Ltdfor Outperforming 😊
Nick W.
Very pleased with the ASHP installation. All the team have been very helpful. A problem was rectified quickly after the install. Handover could have been better as the instructions for Daikin units are unintelligible.
Raymond W.
Excellent. Got about four quotes, all different. Some were excessive, things we didn't need. Some were just expensive. Cinergi came and worked out exactly what we needed, gave us the option of a combi or system boiler or heat pump. At that time chose the system boiler. Never had any problems. Shower and water pressure is fantastic. Very efficient and tidy installation, very professional and personal.
Mike M.
The installation actually took more than twice as long as most similar installations might take due to unavailability of certain parts. Once parts did arrive, the team were very good at doing the work, they were helpful, adaptable, willing and polite and had to work very hard to achieve the required results (I am not easily pleased and can be a hard taskmaster!) The team were not afraid of hard work and during the installation had to try three techniques before managing to get a very heavy piece of the system upstairs to the airing cupboard. They are a good team and are about to extend my solar PV battery system for me.
