	RE: Mitsubishi cycling while on chilled water output By downfield, 6 days ago Forum Air Source Heat Pumps (ASHPs)
	@iaack they have a finned emitter at the bottom a bit like a car radiator so the water runs horizontally through those. Most of the rad is empty but its purpose is to provide a chimney effect so they ...
	RE: Mitsubishi cycling while on chilled water output By IaAck, 6 days ago Forum Air Source Heat Pumps (ASHPs)
	@downfield I don't know how your fan coils are plumbed in but all the conventional radiators I've come across are connected to flow and return at the bottom of the radiator which i assume helps with h...
	RE: Mitsubishi cycling while on chilled water output By JamesPa, 6 days ago Forum Air Source Heat Pumps (ASHPs)
	Yes, but hopefully only for a few days of the year. If you wanted cooling more frequently I would be concerned about the effect of the cycling on compressor lifetime in which case you might want to c...
	RE: Mitsubishi cycling while on chilled water output By downfield, 7 days ago Forum Air Source Heat Pumps (ASHPs)
	@judith not power consumption just the overall efficiency of operation and wear and tear which I imagine is bad for the HP? At the moment power is from solar panels - although I can export surplus so ...
	RE: Struggling to Find a Top Heat Pump Installer? We Can Connect You With the Best Installers in the UK By abam48, 7 days ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa Thanks for the advice - very helpful. I had already seen your numerous posts RE buffer tanks so that is something that I will keep a close eye on as I progress with design and installation. W...
	RE: Weather compensated secondary circuits with Biomass By Sune, 7 days ago Forum Wood Burners, Biomass, Small Scale, Biofuels & Other Heating Alternatives
	Hi @andycoo we do an LK 110 standalone weather compensating actuator with valve: LK are a top notch Swedish made. I haven't tried the German system, although it looks like it also does weather comp...
	RE: Mitsubishi cycling while on chilled water output By Judith, 7 days ago Forum Air Source Heat Pumps (ASHPs)
	Is the power consumption worrying you or are you just concerned about the cycling on principle?
	RE: Mitsubishi cycling while on chilled water output By JamesPa, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	I think that explains it. Unless you can somehow increase load or system volume I think you are stuck with the cycling, unless of course others can suggest something. Bypassing the buffer will proba...
	RE: Mitsubishi cycling while on chilled water output By downfield, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa yes the rads are getting cold and the fans are on - but not 15C cold - more like 17C with a return of 19C. I think the buffer operation point is a good one - that could explain the cycling. T...
