	RE: Ideal HP290 14kW ASHP - how to optimise By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@davesoa Sorry I meant to tag and respond to @cmartinbwmba in my response, whilst nevertheless commenting on your comments for the benefit of @cmartinbwmba and in the context of his/her system. Unfo...
	RE: Ideal HP290 14kW ASHP - how to optimise By Davesoa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa your opinions are always welcome and informed. In my case empiricism has shown I can achieve 20% savings over my previous utility costs and be much warmer than in previous winters by using st...
	RE: Considering MLCP (Multi-Layer Composite Pipe) for ASHP By Majordennisbloodnok, 2 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	I hesitate before responding, but there are points to be clarified for the benefit of the OP and other members. It's not for @deltona to dictate whether someone is allowed or not to find something of...
	RE: Setback savings - fact or fiction? By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	Totally agreed (and hopefully this is the major contribution to energy) - but isnt that contained within
	RE: Recommended home battery inverters + regulatory matters - help requested By Batpred, 3 hours ago Forum Energy Storage
	Yes, certainly not enough could have been tested in any single installation to support a submission. Agreed, given the serious risks in case of misinterpretation, this forum is not appropriate. I h...
	RE: Ideal HP290 14kW ASHP - how to optimise By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	With 'Standard' there are 8 different heat curves (temperature levels) available, I think the idea is that you can change between these (My Vaillant has a very similar concept), whilst still leaving S...
	RE: Ideal HP290 14kW ASHP - how to optimise By Davesoa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	just looked at the HP290 manual. Weather compensation- the manual states “do not change this setting from standard for optimum appliance operation.” Silent mode - “should be switched off otherwise ce...
	RE: Setback savings - fact or fiction? By IaAck, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	@sunandair I think you will also need to take account of the energy lost through Latent heat of fusion e.g. To turn 1 kg of ice at 0°C into water at 0°C (condensate), you need 334,000 Joules (J) or 3...
	RE: Ideal HP290 14kW ASHP - how to optimise By JamesPa, 4 hours ago Forum Air Source Heat Pumps (ASHPs)
	It is counter intuitive but that doesn't mean its wrong. All heat pumps work best if operated at the lowest possible flow temperature. The amount of energy they need to deliver is set by the house, ...
