	RE: MelCloud "Mixing tank temperature" By SUNandAIR, 52 seconds ago Forum Air Source Heat Pumps (ASHPs)
	Yes it may be that your setup has changed the “set tank temp” output and used it for something else or it’s simply not being used which is why it appears at a low temperature default setting. What I d...
	RE: MelCloud "Mixing tank temperature" By Majordennisbloodnok, 17 minutes ago Forum Air Source Heat Pumps (ASHPs)
	It's a good tip, actually, @davidalgarve. All @sunandair is saying is that the Melcloud app adapts the Y axis scale to fit the data points. That's great if you want to magnify any variation but if you...

	@sunandair Hi Sun and Air. I am not sure I understand this: "the set tank temperature shows the temperature your DHW is set at. So it stays at a fixed temperature and doesn’t vary. you can then compar...
	RE: MelCloud "Mixing tank temperature" By downfield, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Yes very pleased with the change from buffer to volumiser. Andrew Millward (Watford based) did the work and advised fitting on the flow side, which seems to work. My "logic" for this is that on a def...
	RE: Evaporator Temperature By trebor12345, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Thank you for the reply. I think you are saying that what I am seeing is normal (Evaporator -23C. OAT -4C. Defrost cycle every 46 minutes).

	You could be right in that it's a region between the 2 dotted lines. It's not clear to me what the chart really means, not my area of knowledge. Maybe someone who's an expert in this area can interp...
	RE: MelCloud "Mixing tank temperature" By SUNandAIR, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Hi downfield, Sounds like you’ve got a result with the volumiser….. I’m curious about where you installed the volumiser…. From the above description did you install it on the flow side…..? And was it ...
	RE: Replacing my 18 month old Hitachi Yutaki ASHP By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Maybe. It says 'outdoor evaporating temperature' (not refrigerant temperature) - its not clear what that means and the graph seems to define a region between the two hatched lines not an operation po...
	RE: MelCloud "Mixing tank temperature" By SUNandAIR, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Hi Dave, the set tank temperature shows the temperature your DHW is set at. So it stays at a fixed temperature and doesn’t vary. you can then compare the actual tank temperature which does vary as hot...
	RE: Replacing my 18 month old Hitachi Yutaki ASHP By trebor12345, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Concerned about the noise and build up of ice. I believe that the evaporator should not be getting down to -23C, based on the algorithm. If I am interpreting the chart correct, at OAT -4C it should o...
	RE: Evaporator Temperature By IaAck, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	For an air-source heat pump the minimum evaporating temperature depends on the compressor design and the manufacturer’s operating envelope. Typical minimum evaporator (saturation) temperature for R32...
