EV and Air Source Heat Pump!
I wonder if anyone is in the same position as me. I’ve got an EV and home charger that are not eligible for Intelligent Octopus Go and am having an ASHP installed this week. Is there a best energy rate for these two? I have been looking at the difference between Octopus Go and Cosy Octopus and seeking other suppliers, but…

COP - diminishing returns on investment?
A bit of a thought experiment, so bear with me.We can all hopefully agree that a COP of 5 is great, a COP of 3 is kinda OK and a COP of 2 is poor. There are plenty of threads where people give hints and tips on how to improve your COP. But what's it worth spending to get that better COP?Imagine, if you will, a household…

Hybrid Heat Pump Scotland Funding
Good morning all. I am exploring a hybrid heat pump for my home. I currently have a worcester system boiler and unvented cylinder. I have had a heat loss calculation at 6.5kw. I am considering a Vaillant arotherm plus 7kw unit with a 250L unistor cylinder and a Vaillant system boiler. I know MCS changed the rules about…

Heat Pump Sizing?
Octopus suggested their biggest unit, 11.2kw but is that the right size I currently have a modulating boiler with weather comp and a smart meter so I know that the boiler runs at a steady 8.2kw (gas input) to maintain the house temp at 20c when the outdoor temp is 0 degrees (flow temp low 50s C). It uses a fair bit less…

Fan Alarm
We have quite an elderly Nibe 2005 Fighter - commissioned in June 2009, and recently it has been shutting down with a Fan Alarm. Nothing about this in the manual. Our engineer says he thinks the only solution is to replace the whole fan assembly (at considerable cost!) but the fan will often work (continuously) for several…

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…

ECODAN Air Source Heat Pump warranty issue
We had an ECODAN Air Source Heat Pump installed in September,2023 through Scottish Power. The package was sold to us with a 2 year Installer Warranty and a 7 year Manufacturers Warranty. We have experienced problems with the system and of our 7 radiators being fed by the system only 2 are hot. These are the 2 nearest the…

ASHP bills huge
ASHP on 24/7 room temperature at 20 degrees C. Our flow rate is 40 operating on weather compensation. You can really tell on usage on a cold day. On Standard Online tariff due to solar panels. Our annual spend was £2459 three bedroom semi detached. Let us know what we are doing wrong.

Air Source Heat Pump Noise
Is it normal for a Air Source Heat Pump to sound louder/rattle a bit when it's 5/10 minutes before the de-ice cycle starts (the fins are iced up at this time).

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…

keeping old boiler with new heat pump
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…
