	RE: Designing my house system with a mix of air to air and air to water By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Sure. Mitsubishi ilife2 slim is the one Ive got. Panasonic do something similar. Myson ivector is another, Smiths Ecovector a low end one. Jaga Strada are a range of fancoils made to look like conv...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@drei this is the formula i was using to rate the radiator output correct to the desired flow temp. =ROUND((((((Flow Temp + (Flow Temp - 5)) / 2) - Target Temp) / 50)^1.3) * Watt Output ΔT50) I’m plan...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@drei good to know thanks. I think there should be more than enough volume in the system. I plan for open loop other than TRVs in the bedrooms in case things get too hot. But if they insist they can p...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@editor so my plan is to go away and upgrade all the radiators myself using the highest heat loss estimate for each room. There is about 5m of main “vein” in the house I will upgrade to 28mm having do...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@editor Heat Geek - 8.45kW, Octopus - 10.27kW, British Gas - 7.69kW I’ll be honest I think BG have made a mistake somewhere as they wanted the most radiator changes yet they had the lowest total heat ...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By downfield, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I didn't because the survey (also done by Regenertec) didn't recommend any radiator changes - and I was planning to install Jaga fancoils anyway, to allow lower flow temps. Also I have triple glazed ...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AndrewJ, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@editor Well, myself as well. I think it would be great if you could get someone from Octopus to talk to you about their technology and design decisions and how this has evolved over the last few yea...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	attached is prelagged in case indicates anything. I’m extremely frustrated with the builder now as he made a throw away comment that had they installed non Eskimo rads it would have been fine. ...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By DREI, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	The only reason Octopus may insist on a buffer, is because they manufacture the Cosy heat pumps, so maybe they have a blanket "safety" requirements in case a user decides to turn off 50% of the...
	RE: The Hidden Secret to a Successful Heat Pump: Pipe Size Matters By colinc, 3 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	The more we learn about about an ASHP potentially replacing a standard or condensing boiler heating system, fuelled by oil or gas, and while being enlightened by this insightful RHH resource, the more...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By Mars, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jords this is an excellent and detailed post... thank you for taking the time to share it. It really highlights some of the challenges homeowners face when trying to make sense of this industry. Thre...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By DREI, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Go with the highest heat loss per room from the table you provided and you can't go wrong. In contrary, if you get oversized radiators, it only means your SCOP is going to be better and cost less to r...
