	RE: All your heat pump problems solved by -- a plate heat exchanger in a plinth! By IaAck, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@allyfish Is this not how district heating systems work. One heat source and multiple heat exchangers?

	Some context to the argument if you are a Housing Association maybe? The government’s Boiler Upgrade Scheme (BUS) currently offers homeowners, private landlords and small businesses grants of up to ...

	I concur. Of the household appliances you've listed, the tumble drier is the one most likely to be eating electricity. Cooking by electricity is probably the next most hungry for power.That can be red...

	EH? so this is a water to water primary to secondary plate heat exchanger, [PHE] buried in a unit to sit under the DHW tank. So it compels every installation to have a secondary circulator pump regard...

	@jamespa I hope I'm wrong but I suspect you will get an error code if it gets too low. Vented systems are so much simpler, it would be nice if heat pumps just had a vented system mode.

	I suspect it's nothing more than convention. The industry has moved away from open vented systems generally and newer boilers/heat pumps probably just reflect this as an assumption. My Vaillant heat ...

	So assuming 45p per liter and 7 kWh per liter thats about 19,000 kWh per year for heating. Does that match with your EPC, it should state it as mine does in the image.Note my projected heating total i...

	Yup, I see no reason to artificially pressurize low temperature heating technology, but as far as I can see that's the method most Heat Pumps follow. Higher temperature systems can kettle, and in tha...

	Feel free to post surveys/quotes for comment if you wish. The motivation for most people here is just to help in whatever way they can and you are entirety free to ignore any comments!
	RE: All your heat pump problems solved by -- a plate heat exchanger in a plinth! By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Understood. The only point I am making is that I'm far from sure that a PHE fundamentally reduces the pressure required in any given system for any given level of performance, in fact I can't see how...
	RE: All your heat pump problems solved by -- a plate heat exchanger in a plinth! By Scalextrix, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa nothing to do with the needed pressure. Current pipework is likely 60 years old, buried in concrete and as such in an unknown condition. Current vented system would max out at 0.5 bar in the...
	RE: All your heat pump problems solved by -- a plate heat exchanger in a plinth! By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I'm not sure that makes any sense at all, so I would question whoever is telling you this properly to examine the alternatives. Fundamentallly the pressure you need in the system is determined by the ...
