UFH Overlay System and Heat Pump Which Pipe Size?
Hello, I am looking to install underfloor heating to the ground floor of my house. This will initially run off a boiler but I may switch to a hybrid system in the future with an air source heat pump. The UFH will go on top of a timber suspended floor which has insulation between the joists. This will be then tiled on top.…

Frozen Heat Pump
Our first winter with a heat pump and it is very cold here (around minus 10 last night). The back of the pump has frozen over: One side has rather a thick covering of ice. Is this normal? Online reading suggests it should run a defrost and low refrigerant could be an issue? It's a 12kw 6th Gen Samsung. Thank you in advance…

Anyone compared British Gas vs Octopus heat pumps?
Im keen to get a heat pump and have had a decent quote from octopus £2800 for 8 radiators and full install. I have also seen that British Gas promise to price match so wondered if they were better or if anyone has looked into this already and worked out who is better? Im keen to get a decent COP and was worried about…

Heat Pump Quote
Hi everyone, I recently got heat pump quotes from octopus as I am considering making my home more green after getting solar panels. I went through octopus and they quoted me 400 after the government subsidy which I felt was an absolute steal. Issue i have is that the cosy 6 which is more aesthetically pleasing can't go…

I currently use an oil combi boiler central heating but I am considering to switching to an air heatpump. However, being aware of the potential downsides I am wondering, if there is the option to keep my old boiler so that I can either be able to switch between the two, or at least have the option to go back to using my…

Air to air or air to water?
OK I realise this is a pretty open ended question but what are people's thoughts on air to air heat pumps (basically split air conditioners) v air to water? I've recently installed a home battery and switched to Octopus Go, so the large majority of our electricity consumption is at 8.5p/kWh, averaging about 10p/kWh. Our…

Heat Pump in 1920s 4 bed detached with coal dust cement - trusted installer?
I would love a Heat Pump (HP). But because of coal dust cement my Octopus SM2s don't communicate with Octopus - (Cardiff O2 comms). I have cavity wall insulation, large often 2 sided radiators and good roof insulation. But I am wary..... I would go with Octopus but suspect they would not contemplate my house (don't do…

Can Heat Pumps Be Turned Off in Summer?
With our gas boiler, we turn the heating off around April time and it doesn't come back on until October-ish - obviously depending on temperatures. How does this work with a heat pump and hot water?

Heat meter - Fun & games
Been thinking about fitting a heat meter for a while so that I can get an accurate picture of just how much energy is pumped in to the central heating system here. With hard data in front of me, it will be much easier to select a suitably rated heat pump when the time comes without any guess work. Having looked at the…

Daiken ASHP hot water
I find my hot water tank heats quicker than I need it to and is averaging a COP of just less than two (although admittedly this will include the weekly legionella cycle which after much research I decided to keep). This suggests to me that that the ASHP is running hotter than I need it to for hot water. Is there a way to…

Heat Geeks
I'd seen many of the Heat Geeks videos and got taken in by the hype. Despite having 8mm microbore I'd seen the videos which indicated this isn't a deal breaker so I paid £375 for an assessment.The engineer arrived and verbally told me this would be a straight forward installation. The house has a heat loss estimate of 5kW…

Air to air heat pump?
Hello everyone. I’m in the process of renovating a 1950s 3 bed semi, and my priorities are insulation and heating. The current heating system is old storage heaters, and immersion for hot water. I’ve been researching different heating systems for a while now, and would appreciate any input to help in my decision. I’ve…

Bad ASHP Install on New Build - Legal Stand Point?
My wife and I bought a new property in January this year (2024) which was sold as a heat efficient modern new build that would be low on bills due to the air source heat pump installed. We started seeing our electric usage look rather high and after a lot of investigation, and cost to have reports done of the heat pump, it…

Air-to-air multi split heat pump - bungalow without boiler/radiators
Our bungalow is (was) heated by a gas warm air heater (no radiators, instead there's ducting underneath the floor and vents in the floorboards, where the warm air is coming from). This heater has finally packed up - I tried to use it in the recent cold spell and it couldn't get going and flashed a red light. It may need a…

Homely heat pump controller
I saw a Heat Geeks video interview with the founder of Homely and was interested to note that Samsung is one of the brands it is designed to work with. Having looked at the Samsung installation manual, prior to an ECO4 installation, I got the distinct impression that the inbuilt controls are pretty rudimentary and I might…

I was going to put it on auto mode and set timers but read this is an expensive way to use it? Any advice on best settings to use…
