Marvel Heating are a very good team

I was thinking of getting an ASHP installed and asked some of the big energy suppliers to quote. They did and they were eye watering. So I cast around for a more local heating company and came across Marvel Heating. I contacted them and someone came out to explain what could be done and left me to go through everything by myself with no pressure, after I had been through information I had more questions and contacted Marvel about them, Dwain, the owner replied and came out to see me and we discussed what I wanted, he explained what I could and couldn't have and we agreed there and then that they could do the work. A member of Marvel heating came and did a heat loss survey, which sets out what system is needed, ASHP, hot water cylinder and radiators. That done a date was booked for it to be fitted. In all Dwain and Marvel Heating are an excellent team.

I had an Ecodan R290 8.5kw heat pump fitted with a twin coil hot water cylinder, as I had just changed the radiators, they didn't need doing. The installation took 4 days instead of 3 due to the heat pump arriving damaged from the supplier, this was exchanged for a new one. The system was commissioned in June and everything got hot. Due to having Solar Thermal I didn't need to run the heat pump until the end of September and a problem was identified and quickly resolved with a call and photos to Marvel. The problem was a temperature probe in the wrong pocket on the hot water cylinder.
The system is running well and the house and hot water are hot although I don't know if it as efficient as it could be. Everything runs from an app that is good enough to set temperatures and set timings, but to get into the workings of efficiency you have to go through a control panel and even after watching multiple YouTube videos I'm still no closer to working it out.

In all I would say that if you are interested in an ASHP contact Marvel Heating.

Overall Marvel Heating were great

Overall Marvel Heating were great, the install didn’t go exactly as planned but when little things go wrong it shows how well the company is with how they put things right and deal with things promptly.

Overall Dwain stands out the most, weekends, night times he was available and working to make sure that the job got done.

First contact with Marvel on the sales side was easy, it does take a little time to gather information to get a price for the system, you also need to have a survey carried out.

Once the order was placed the install team was straight on it and my job was started much quicker than others were offering, 3-4 weeks at the time while others were 12 weeks.

All the engineers that attended were spot on, good workmanship and tidy. Just what you would like and expect from a decent company.

There was a problem with the fuse board, the wire wasn’t large enough to cope with the load, I had a car charger on the same board and when both were running it tripped. After raising this with Marvel, they quickly investigated and sent an engineer to install a new larger wire. Again, some companies might have argued but the work was carried out and in a timely manner.

As for the actual heat pump, I had it installed in August, I had my gas took out (by Marvel) and it was very worrying in case it didn’t work. It’s the middle of November and we’ve had some cold nights and I’m quite surprised and pleased with how it works. I was used to gas, turn it on and quickly the house starts to warm up, with a heat pump you still have that control but it takes a little longer, but when you get used to it it is no bother at all.

The control and app has timers that you can set up, it’s well worth setting these up, it’s easy to do, and then you can play around until you get the temperature where you want it, just like a gas boiler.

There’s some negativity about the MELCloud app and people saying the functionality isn’t that great and that put me off a little but it’s really quite fine and easy to use.

I have a 5 bedroom detached house, with 17 rooms, the Mitsubishi Ecodan unit is doing just fine. Water is stored at a lesser temperature, the cylinder will be sized bigger than a normal gas boiler but we’ve not ran out of hot water yet and it’s still as hot out the tap and shower.

I’ve also got solar and batteries, with tariffs that are available with Octopus my house now has negative energy bills, they are now paying me for energy that I export over and above what I draw from the grid.

Even without solar and batteries, I can notice the difference in better energy usage than with gas and I would still recommend a heat pump.

Would I use Marvel again, yes I would and I’ve recommended them and heat pumps to friends and neighbours.

Very happy with the company

Marvel were not the only company we approached about air source heat pump installation, but they were the most honest, open and helpful company we found.
From the initial survey through planning to installation everything was handled professionally. The installation team were really impressive, our home had some quirks that required solving as the installation progressed and the engineers handled everything in their stride.
The system was wired and commissioned the day after installation without any hitches. Operation was explained and the Mel cloud app was easy to use to control the heating.
It has performed exactly as we were told it would, if not better; hot water temp and pressure is better than with our old combi. The larger radiators are up to the job of heating our home but are not that much bigger than those for our old system. And we only needed one additional radiator in our kitchen.
Overall we are very happy with the heating system, we were told by people it would be cold and noisy, it is not. The pump is close to our bedroom window and even with the window open we dont hear it. The radiators are cooler than with a gas boiler, but that was expected and is part of the system design as they run cooler but longer.
Marvel were recommended to us by a good friend, they have been every bit as good as we were told. I'd happily recommend them to anyone considering heat pump installation.

Marvel Heat Pumps definitely lead the way!

We had an impeccable service from Marvel Heating from start to finish of the installation of our air source heat pump. The salesman was extremely informative and helpful and the rest of the team were outstanding ranging from engineers, plumbers and electrician. All headed by Dwain Byrne MD. The work was carried out with extreme care and tidiness We are now reaping the benefits of having the installation expertly done.

Honest, tidy, high quality respectful people.

The engineers that came were not only knowledgeable and professional, but they were also very respectful of our property.

Anything we asked was never too much and they even did little extras like move some radiator pipes so that the job just looked neater when finished 😁.

After installation I have had the pleasure of speaking with them about the installation and to organise a battery install (which was also done to a high standard and placed exactly where I wanted it to be).

As a testament to the quality of workmanship our installation was chosen for a random quality audit inspection by the bus grant scheme. Today the results came back. Which in fairness was no surprise, but it was a pass with flying colours.

If you are considering a heating company I would honestly look no further. I would also recommend a heat pump. Once set up and tailored to your home (which is well worth spending time to do so) it just works quietly in the background.

Mitsubishi Ecodan ASHP

Knowledgeable sales person , no pressure to buy. Detailed inspection by engineer to ensure suitability and answered all questions openly and with great detail.

Installers worked quickly and professionally and installed to a high standard.

Had some teething issues with the system , a little difficult to get in touch and get an engineer out due to distance.

Issue was rectified quickly and since had no issues , very happy with performance of ASHP . Initial worries of house being cold were soon a thing of the past , house is lovely and warm.

Great incentives after sale on servicing.

Would recommend

Great experience with Marvel heating

Great experience with Marvel heating. Starting from initial visit, providing quote and right suggestions to the installation process - all went very smooth. All my anxiety was allayed by the team installing it and it was a tidy work and they took responsibility of clearing all rubbish as well. Though i don’t have any issues with the heat pump, i feel the team is always there for any trouble shooting and there is good ongoing customer service. Overall i am very happy with my choice of going with a heat pump and happier with the choice of going with Marvel. Thank you.

Overwhelmingly positive experience

Marvel Heating made the installation of my ASHP perfectly simple. They had answers for every question I had and the whole process ran on time as planned. My life and home suffered very minimal interruptions, as the plumbers got all their jobs done in a day, including removing the boiler and all of the previous heating equipment, and the very next day the electrician completed him work.

First class installation

The whole installation was handled in a first class way. From first discussions to final switch on all was excellent. All the staff I dealt with via phones calls were exemplary and the installation guys were efficient, thoughtful and professional- I would recommend this company without hesitation.

air to water heat pump, so far so good.

In our case marvel fitted an air to water heat pump system installation by Marvel Heating, which attracts a £7500 grant from the government, this meant we paid around £6.5k and got a heating system costing around £14k. Our boiler had broken, and a decent replacement would have cost £5k, so it's a good deal. Now have no gas bills and no gas standing charge ever again. Our electricity is from solar panels, and the extra is from renewable green energy (Ecotricity).

Any radiator upgrade was a flat £200. About half of ours needed upgrading.
Our heat pump is a Mitsubishi ecodan 8.5kw. We have 3 beds might extend to 4. House is well insulated. So far so good. We have an app a bit like hive, seems good. Also have a movable control in the house, and one attached to system. Installation took 2 days for plumbing, 1 day for electrics to make it work

24 solar panel install with battery storage and hybrid inverter.

I recently had 24 solar panels with a Fox Ess 10kw hybrid inverter with 2 10kw battery storage.
Amazing install and the work is to a very high standard.
The app is fantastic and I can monitor everything.
They also installed another Fox inverter on my old solar system that links into the app as well. Can say the install was swift, quick and was fitted in with short notice.
Great company and easy communication.
I would definitely recommend them to anyone.
Plus will be going back for more solar equipment to be installed off them very soon. 👍.

Heat Pump and Solar Panels

I recently had an Air Source HeatPump and Solar Panels installed at my property. Adam came initially and we discussed everything in detail. A walk through was conducted with Dwain before the installation. On the day of the installation the engineers came on time as arranged. All the work was done in one day. The work was done to a very good standard. The men were very respective of my property and myself. Time will tell about the equipment installed but at this point I am very happy with it.
I can honestly say that I would recommend Marvel Heating to anyone.
