	RE: Solar Power Output – Let’s Compare Generation Figures By Transparent, 13 minutes ago Forum Solar Photovoltaic (PV)
	I concur with that analysis. If the PV panels are resting at ground level, and not embedded into it, then you don't require planning permission.Local Government Councillors have asked their planning o...
	RE: Radiator sizing sanity check By JamesPa, 14 minutes ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	Air comes out of solution over time. I had to bleed one radiator every second day for a month after the installation was done and only the other day one year after installation had to bleed again, no...
	RE: Cascade 2x Grant Areona 10kw ASHP - Ongoing setup issues By JamesPa, 16 minutes ago Forum Air Source Heat Pumps (ASHPs)
	I presume he didnt say why? I dont personally understand how this can be the case (so suspect BS) but of course willing to listen to arguments. Interesting. 2-4 would be great but certainly ...
	RE: Cascade 2x Grant Areona 10kw ASHP - Ongoing setup issues By adam, 43 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Ok so I’ve called Grant this morning and talked through the issues. their advice was that my flow rates are likey too high which is what is causing excess defrost cycles. Ideally I should have...

	New rads, new TRVs, new lockshields, power flushed, new pump 37l/min flow, i bled all rads, 3 air removal valves on system, plumber balanced and not touched since. To the touch, upstairs and downstair...
	RE: The Great British Heat Pump Owner Persona Survey: Let's Build Our Archetype! By Stuart, 54 minutes ago Forum Well & Truly Off The Grid
	ASHP INSTALL: An absolute nightmare from the start. Our property has been ruined, we have a leaking roof, and the house is cold. We have installed two wood burners to keep us warm. Oh, the green Irony...
	RE: Radiator sizing sanity check By JamesPa, 56 minutes ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	Well that puts a different light on it altogether! Radiators not getting warm would be due to one or more of (a) valve blocked - note that TRV pins can get stuck if they are shut off for an extended ...
	RE: Radiator sizing sanity check By Papahuhu, 1 hour ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@jamespa its weird. It’s -1.5C outside, I’ve been monitoring the temp of the radiator (not the room) and it’s only running at about 24 C. The current outlet temp on the heat pump is 38C, I would have...
	RE: Water Hammer After Heat Pump Install By JamesPa, 2 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@jaynieq I wish you luck with this one. I think the main thing I am telling you is to focus (when discussing with any plumber) on the water hammer and the fact that you went from an indirect system t...
	RE: Radiator sizing sanity check By JamesPa, 2 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	Thats good. Keep the faith, rad swaps are easy and rads are dirt cheap. Even I can do 2.5 a day, I am not a plumber and absolutely detest plumbing!
	RE: Radiator sizing sanity check By Papahuhu, 2 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@jamespa Thanks We are running completely open loop and the upper floor rads are already reaching the same temp as the lower floor rads. So rebalancing can’t help, the room under it easily reaches de...
	RE: Testing new controls/monitoring for Midea Clone ASHP By cathodeRay, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Mine was installed in early Feb 2022 and may well have left the factory in 2021, meaning quite a long interval between manufacturing dates. The varying emphasis in the wired controller manuals on the ...
