	RE: Ecodan unable to hit legionella target temp - what's the consensus? By 9jwr9, 7 minutes ago Forum Air Source Heat Pumps (ASHPs)
	@benson Thanks for the reply. Ecodan has a pre-programmed legionella protection cycle where it takes takes the hot water temperature up to 60+ degrees once every 14 hot water cycles to kill any bacter...
	RE: Ecodan unable to hit legionella target temp - what's the consensus? By benson, 13 minutes ago Forum Air Source Heat Pumps (ASHPs)
	I think the key question potentially is why you are trying to hit a target temp of 60, all of the time? Why don't you just set it at 50 which the ashp can manage, and be done with it?
	RE: Ecodan - Legionella Operation Time and Target Temperature By 9jwr9, 14 minutes ago Forum Air Source Heat Pumps (ASHPs)
	@old_scientist hiya mate, did you ever get to the bottom of why your immersion would cut out just before 60? I'm having the same issue with my Ecodan, where the immersion is tapping out at 59 (cycling...
	Ecodan unable to hit legionella target temp - what's the consensus? By 9jwr9, 20 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Hi all, We have an Ecodan 14kw (PUHZ-HW14VHA2-BS) paired with Joule Cyclone Platinum 300l cylinder and a buffer tank. Heating is all working great, however the hot water cycle defaults to the legione...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By JamesPa, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	Flow rate x delta is how heat pumps monitor energy to house, no reason for cosy to be different so presumably this is what it does.
	RE: Ecodan - Legionella Operation Time and Target Temperature By 9jwr9, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@trbob hiya mate - did you ever get to the bottom of why it was maxing out at 59.5 and failing to hit 60? Was it a problem with the thermostat/immersion or a mitsubishi software issue as others have s...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AgentGeorge, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@swwils I can figure out how the cosy knows the energy input, but how does it calculate the energy output it sends to the house I’ve got an open loop downstairs UFH network and a TRV regulated upstair...
	RE: Advice on internal circulation pump noise By JamesPa, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	Welcome and I am sorry you are having this problem. The obvious answer is to delete the buffer and secondary pump which will remove the problem entirely and almost certainly improve system perf...
	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By swwils, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	@harrisonc mine has level 3 MID monitoring and you can see this power ramping. It's not completely weather comp control, there is a thermostatic element. Basically the cosy should be thought of in ter...
	RE: Heat Pump Heats the House… But It’s Not Cosy. Emitter Changes or System Tweak? By Mars, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	@alastair, in short, no, increasing emitter capacity won’t harm the heat pump. In fact, in most cases it does the opposite. Bigger or additional radiators give the system more surface area to emit hea...
