	RE: Optimum new build house design for Heat Pump By JamesPa, 25 minutes ago Forum Air Source Heat Pumps (ASHPs)
	A single design temp of 35 or less really would be the way to go. If it were my newbuild I would be insisting on it unless I had concrete proof (not just plumber BS) that it was not practical. Bear ...
	RE: Biocide and Inhibitor By JamesPa, 32 minutes ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	One school of thought says put almost nothing in and instead treat only to VDI2035 which is a German standard. So far as I can see there is a lot to be said for this approach. My cynical side says t...
	RE: Biocide and Inhibitor By Mars, 43 minutes ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	I saw some chatter last year about general environmental impacts of biocides/inhibitors (potential for runoff or long-term aquatic effects if not handled properly when systems are flushed).
	RE: Optimum new build house design for Heat Pump By MikeF, 43 minutes ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa They will see what the plumber is suggesting when he gets back the projected heat loss, Maybe with a fancoil on the landing, the design temperature can be 35 or less cheers
	RE: Optimum new build house design for Heat Pump By JamesPa, 58 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Im not sure what your thought process is here. Are you suggesting running with a max FT of 40 rather than the max of (say) 35 that the UFH is likely designed for. If so how will you stop the downsta...
	RE: Optimum new build house design for Heat Pump By MikeF, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I will see what the plans are for the hallway, it should be possible to use it to get heat upstairs. When balancing the UFH flows the hallway would need a greater flow because of the volume ...

	Possibly, given the context, but we don't know for sure. IDDAH to spell things out (it doesn't do any harm).

	@cathoderay I took it to mean Anti-Freeze Valve.🤨 Regards, Toodles.
	RE: Biocide and Inhibitor By cathodeRay, 1 hour ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	Can you specify what the 'concerning press' is? It may just be typical media scaremongering. It is also a good idea to spell out what an abbreviation stands for the first time you use it. AFV? Armoure...
	RE: Optimum new build house design for Heat Pump By MikeF, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@majordennisbloodnok I agree that they should look at MVHR, but will need to get their builder onside, some builders don't think air-tightness matters, so they look for the quickest option, not the be...
	RE: Creative trials on Night-time Setbacks to @ faster recovery, improved comfort and even greater energy reductions. By Old_Scientist, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@sunandair we operate a very similar overnight setback with our Samsung ASHP using a 3rd party wireless programmable room thermostat. The heat pump is oversized, and even at minimum output will output...
	RE: Radiator sizing sanity check By JamesPa, 3 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	The nominal will be the flow rate for rad dt5 at full output. Ideally you should be looking to achieve this but.. your 16kW heat pump is likely well oversized so in practice it may not matter. &nbs...
