Can you swap a Gas boiler for an Air Source Heat Pump? 

Think very hard before taking the plunge with a heat pump. I had a top-of-the-range Daikin Altherma R32 16kW split system with upsized radiators installed in June 2020. It was great for... 3 months. Then communications errors started between the indoor and outdoor units, which caused occasional glitches. The heat pump stopped completely in Dec 20 due to a refrigerant leak, and a replacement outdoor unit was supplied within 5 days (cudos to Daikin on that occasion). Then after a few months the control PCBs in both units needed changing due to ever-increasing comms errors. Then in late November 2021, the system became very inefficient due to another loss of refrigerant and could barely heat our bungalow to a modest temperature. It full-stopped a week later and the system had to be put into emergency mode, where internal electrical backup heaters were employed to heat the radiator flow water (no heat pump action, no efficiency). This went on for 9 WEEKS while awaiting spares, at an average consumption rate of over £100 per week for space heating, and the bungalow could just reach 19 deg when mild outside. At the end of this period, the heat exchanger was replaced and the system was recharged with R32 refrigerant. All was good for 3 weeks, but then the system alarmed due to low R32 refrigerant - again. TAs of now, the efficiency is going down, and the running costs are going up. I am yet again waiting for an engineer to come and fix the leak and recharge the system. Electricity is going up 50% tomorrow...

I have been a building services engineer most of my life, the past 20 years in local authority - It is so refreshing to listen to someone who knows what they are talking about without the spin!

Very informative video, thanks. I've just fitted Central heating to my daughter's back-to-back terrace. A heat pump is not an option for her as the house only has a front! But good info is never wasted.

You should also do a video of an actual installation from start to finish to show just how disruptive an installation can be

Great video. We had our daikin altherma 13 installed a year ago and it's been brilliant. This video would have been great to see back then as it explains way better than anything I was told at the time 👌

That's a great video. Really informative thanks for posting. I also noted that you took your outdoor shoes off while in the customer's house. This is always great to see. That or shoe covers. Very respectful. You're hired! 🙂

Great video. Really informative. I have read the reviews good and bad, normal stuff some people unfortunately have had horrendous experience some no issues. So helps no understand the failure modes and where to talk about during installation.

Really good, clear, informative and helpful video. Thanks for putting together!

Great video. Well put together and informative. I work in the industry and learnt a few things. Keep them coming :-)

This video communicates such a positive image of EcoBubl - I so wish we had used you to install our ASHP. We had a nightmare of an installation - 3 days turned into 16 days over two months! Experience, knowledge and competent planning up front … Great video, informative and entertaining too!

Fantastic explanation of the process 👍👍👍

Very clear, knowledgeable presentation. Shame you’re not near us.

Good presentation but for me heat pumps are a total no no. The main reason being cost, I built my house 40 years ago and heating and hot water is provided by a Worcester Highflow floor mounted combi, which is cheap to run. The estimated cost of putting a heat pump system in is around £20,000, money I do not have or wish to spend. The disruption potentially caused by the installation would be enormous, something I am not prepared to contemplate.

Brilliant presentation, some fun but lots of knowledge there.

This is a great introductory video to the practicalities of heat pump installation. If only all suppliers were as open, honest and pleasant to deal with. It makes clear the preparation and fore-thought needed to ensure that the results will be a success in terms of the use of available spaces and aesthetics, as well as heating efficiency. The video helps build confidence that the switch to a heat pump can be managed, when you have the right company to design and fit the system.

Every point made is perfect for engineers to consider and the home owner 👍

what an excellent video, made it really easy to understand

Fantastic video! Incredibly informative and interesting video as usual :)

Great prez, thanks. IMHO a critical issue with all these tecs (I am also looking at "big-battery+inverter from off-peak" and "Zepeo -or competitor") is finding a

I love this walk through. Watching it makes me aware of how careful we’d need to be about getting the right firm in to assess the property - if only you were in Yorkshire!
