  I was dubious about using this company, and I was right to be. On quotation I was told to build a concrete pad for the pump to sit on at my cost, the team installing it said it could have sat on the flags laid already with rubber bungs on the feet of it. Their price was competitive. As we were coming into the summer the issues with the radiators became apparent later. They weren't warming up properly, clinking, which never happened before. They came out, said they had fixed it, they hadnt, but also after their visit we lost pressure in the water, we booked in a visit for a 2-man team, because they was going to change the shocking pipework they had done when changing the radiators originally, i took a day off work and they told me I had the wrong day, and it was the next day i was booked in for. When the engineer came (alone, not a team) he said that he was only asked to do this last minute as it had been missed the day before. He came with approximately 6 tools in his toolbox, never have I ever seen a grown man take over an hour making a hole in chipboard flooring using a broken screwdriver, before asking to use my drills. Then after he done some work, as he was alone, I had to run around the house bleeding all 17 radiators whilst he watched the pressure gauge near the tank. He left at 7pm! Leaving me to sort the floor he had ripped up and scorched skirting boards..... but he came back again because he had left something off the tank which leaked all over the garage floor. Tie this in with the fact electricity has skyrocketed makes the pump so expensive, makes their whole sales pitch of "itll pay itself of after X amount of years" as so far its costs a fortune. I have refurbished my entire house.... this has been hands down the most stressful part.

  I would like to thank the entire Marvel Heating team for the flawless service they provided. From the quotation stage to the final delivery, they demonstrated a highly professional approach at every step. The installation team in particular worked both quickly and neatly. They also completed the job earlier than planned, exceeding my expectations

  Excellent service from Marvel Heating from start to finish. Rob was polite, knowledgeable and never pushy, and I was consulted at every stage — including having my input on where the heat pump should be located. The installers, Darius and Craig, were fantastic — hardworking, professional, and very tidy. Any minor niggles after installation were dealt with quickly by the customer service team. Best of all, the house is now consistently warm and it’s costing less to run than when we were using gas for a few hours a day. Highly recommended.

  Generally good, with a few issues along the way. Very friendly team. You can tell they're genuinely wanting to help you. Ours was a large job: installation of underfloor heating throughout the property plus an air source heat pump. The sales process was straightforward, informative & clear, with a sales director coming to our house to talk us through our options, explain how it works etc. This was followed by a site visit, once we'd signed up, which was undertaken by engineers who really knew their stuff. We did question whether the pump would be sufficient for our property, and Dwaine and the team insisted that it was. We have now had our first winter with the heat pump & underfloor, and it all appears to be working quite well (after a few small issues with Marvel were swift to resolve). The main negative we have found with Marvel has been communication (which they seem to have resolved since, by hiring some more manpower to head up some of the operational elements). During the course of the time we worked with Marvel, communication was a pain point, as a lot of the comms seemed to bottleneck with Dwaine, Marvel's key decision-maker - clearly a very knowledgeable and busy man. However, I understand they have recruited someone else to manage the operations in those moments where Dwaine is unavailable. Broadly, Marvel offer a good service, with some genuinely great people who work for them. With some improvements to their operational model, reducing bottlenecks, spreading accountability, they could easily be an excellent, category-leading company.

  This is our unbiased review of Marvel Heating & Renewable Energy Ltd. I personally looked for many weeks to see who installed Heatpump Central Heating Systems. I came across Marvel on their site and arranged for a free survey of our home. From start to finish our experience is nothing short of pure delight. I will mention individuals as purely a honest and grateful acknowledgement of their services. Dwain Director a honest and respectful owner. Morgan engineer absolutely outstanding individual. Ellis outstanding engineer. Reece outstanding engineer. Harley outstanding engineer. Adam electrician fantastic bloke again responsible and respectful. We cannot praise this company enough from start to finish it's been superb. As for recommendations we'll look at our review it's speaks for itself. All the best to each and everyone connected with Marvel...... Regards Martin & Marie Culpan....

  I have been impressed with every Marvel employee involved in our air source heat pump installation, from the initial phone call and feasibility visit through to the engineers coming out to tweak our system to get it working perfectly. Our house was perhaps not the ideal property being an older house with multiple extensions, complicated pipework including some microbore, the need for a fairly long outdoor run due to having no sideway, and a large, difficult to heat open-plan downstairs living area. There has never been any hard sell from Marvel, just a very honest assessment of what they could and couldn't do. The engineers have all worked like Trojans - initially having to manually lift the ASHP up to a first floor wall location to limit the external run, and then eliminating all the 10mm pipework added by different plumbers over the years. We have had to have several follow up visits over a couple of months, but it was never suggested that we would have to put up with a system that we were not quite happy with. Having just got through a very cold spell over Christmas and New Year without the need for any back up heating, I can say that I am delighted with the all round, all day (if you need it) gentle heat provided by the ASHP. We had the ASHP installed in September 25, but also had solar panels and two batteries installed in June 25. The batteries allow us to buy virtually all of our electricity at £0.14 kWh using the three cheap charging periods offered by the Cosy Octopus tariff. On the coldest sub-zero days, the daily cost will be for around the same as two shorter bursts of gas central heating each day plus some gas fire top up last winter. On slightly milder days, the daily cost is much less. I plan to switch to the Intelligent Octopus Flux tariff for the summer when all we do is export (all ASHP costs will be covered by the solar panels). This offers much better export rates than the Cosy tariff. I will then switch back around September when the exporting diminishes and we have to use the grid again. Overall, looking at our use against costs so far, I'm anticipating saving about two-thirds of our combined energy bill. It has all required a significant up front investment, but it will all pay for itself over time. More importantly, we get a much better 'quality' of heating throughout the day. As a recent retiree, this is perhaps the most pleasing outcome of switching to the ASHP. Many thanks to everyone at Marvel.

  This is a good system and it is working well. There are a lot of things to consider with this sort of system and the company is good at keeping you informed. Their post-installation care has been particularly good - there were a couple of issues that needed addressing after the installation, but these were soon put right. The chance to chat with an engineer over the phone is really helpful in maki g sure you have the system running properly. Well pleased.

  I have always been hesitant of using firms that claim that they improve your home in some way. So, when I thought it was time to have a heat pump installed I asked my neighbour to find a heat pump installer that I could trust. After trawling through the Internet, she came up with Marvel Heating and Renewable Energy Ltd. Kevin came first to ask about our hopes. We asked for a heat pump that could warm the whole house to 22°C.He explained what we would need to achieve this temperature we required and created a proposal and quotation. Next, Adam came to do a survey, measuring all the rooms from which he made calculations necessary to find the capacity needed for each radiator to produce 22°C throughout the house. Jack produced his report after walking through our house making sure the installers would not hit any snags. Unfortunately, Jack clashed on where to install the heat pump and its capacity required to manage 22°C. Changes were made to the proposals increasing the capacity of the heat pump that were signed and installation began. The date of its installation was really hot. The installers worked really hard, but found that my thermal solar panel was producing water that was too hot and they insisted that they disconnect it. I had used water from this system for 35 years and was very upset when they asked for it to be disconnected. Not all the radiators came that day, and led to some delays and confusion for the next few days. There is also an issue with the waste from the installation. Two men were very perturbed when they did not find any waste outside the house ready for them to pick up. I was able to show them where the remnants of this waste was so they could take it away. Meanwhile, another delivery, of radiators came, but now there was no one to install them. Eventually, arrangements were made to install the remaining radiators and an electrician to finish the job. This period could have been better organised. Mistakes were made could have been avoided. At one point, I was left without any hot water. However, all these issues were resolved when Jack turned up to resolve all these problems. I did have my thermal solar panels reconnected, but they all now subject to modern regulations and so cannot produce the same temperature of water as previously.

  I was visited by Nigel after my initial enquiry and he explained in detail what was involved. After paying the fee, the survey was organised quickly, the paperwork followed within a few days and the installation was very efficient. A minor problem with settings was resolved on the same day and I am very happy with the heat produced by my heat pump.
