	RE: DHW heat loss through pumps. By Ubert767, 11 hours ago Forum Domestic Hot Water & Cylinders
	@jamespa I have a DHW recirculation circuit in my house, the circulation pump was originally controlled by a conventional central heating time switch, programmed to fit in with our domestic routine. ...
	RE: Electricity price predictions By Jeff, 11 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	The plan is not to switch off for extended periods. Also it planned to be an opt out system so customers can choose not to take part, but I suspect this would lock customers out of the cheapest tarif...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By JamesPa, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	The problem comes only if you can't turn the ft down sufficiently because of the firmware limitations. At that point you will have to run thermostat controlled. I fear they are trying to make it easy...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AndrewJ, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	I was thinking about this a bit. It's probably not a problem if they are all similarly oversized otherwise the flow temperature might be too high for some and maybe not enough for others. Not helped...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AndrewJ, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	There is a Facebook group in which the lead engineer participates but he doesn't get involved in every discussion and his responses are often cryptic and I've never seen him follow up if someone asks ...

	we are talking the same thing. Its crazy if its really like that, but Octopus are, in fairness, pursuing a 'low installation cost, good enough' approach rather than the 'maximise cop at all costs' ap...
	RE: Electricity price predictions By Batpred, 12 hours ago Forum Electricity, Tariffs, Monitoring & Providers
	I agree, the operation of a system managing hundreds of thousands of consumer hosted batteries would entail lots of effort and so cost managing contracts, monitoring systems (whether data centre hoste...
	RE: Installer Fitted 9kW Instead of 11kW Heat Pump and Changed MCS Paperwork - What do I do? By Toodles, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa Yes, the OAT sensor is situated on the back panel, near the top edge and in my case, it is protruding from the grill slightly and has a transparent tube over it for protection. As to accuracy...
	RE: DHW heat loss through pumps. By JamesPa, 13 hours ago Forum Domestic Hot Water & Cylinders
	Ah, you have a water circulation loop, (like in hotels) which does exactly that, keeps water circulating round the house continuously so you can enjoy the benefit of instant how water 24*7 rather than...

	Interestingly, being a timber framed house, all internal walls are plasterboard. The internal walls which have an external facing are plasterboard backed by insulation backed by vapour barrier backed...
	RE: Ecodan ASHP Low COP and Unstable Compressor Frequency By lukewarmbath, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	Just to clarify, returning water from UFH is colder than returning water from radiators. Just checked with a infrared thermometer and approximate temps were: Flow temp to emitters: 31.5 Return...
