	RE: Heat pump monitoring - what are you using? By Johnmo, 38 mins ago Forum Air Source Heat Pumps (ASHPs)
	Got the cycles to about 15 min on and 30 to 40 mins off. But although giving a decent CoP the energy used was high, because I believe the quality of heat delivered was poor. To much heating a bulk of ...
	RE: Low shower pressure after ASHP retrofit By Johnmo, 7 hours ago Forum Air Source Heat Pumps (ASHPs)
	Most mixers uses a balanced flow i.e. the flow pressure from hot and cold is the same. This is how it is normally achieved via the combined valve at the UVC Attachment : image.png If you don't...

	RE: Will heat pump heat hot water without increasing the temp in my home? By Judith, 18 hours ago Forum Air Source Heat Pumps (ASHPs)
	Certainly if you can get an inverter which will take a battery (later) then that would be great, and a saving for later. We have solar thermal (from years ago when it was the only option) and it’s ver...
	RE: Heat pump monitoring - what are you using? By Judith, 18 hours ago Forum Air Source Heat Pumps (ASHPs)
	Good info @johnmo Are you using a calculation to achieve the COP or does the equipment do it for you? What is the total current for the ashp+pump? What is the standby current?
