	RE: Do I need to change the control unit when replacing my Ecodan Air Source Heat Pump By Majordennisbloodnok, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Kind of you, @calumm, but it was @f1p who did the heavy lifting. Either way, glad you've got an answer. Pity the answer wasn't your ideal one.
	RE: Minimum system volume By bobflux, 2 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	The "thermal comfort" we feel is a mix of air temperature and infrared radiation received by the body. This radiation comes from every surface in the room. In a house with bad insulation, walls will b...
	RE: Do I need to change the control unit when replacing my Ecodan Air Source Heat Pump By CalumM, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@majordennisbloodnok - thanks so much. That has been really helpful. 🙂
	RE: Minimum system volume By Old_Scientist, 2 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	We have large radiators as our emitters. Room temp is 20.0C, flow temp is around 33-35C at temperatures where we may see defrost cycles. From memory (which is not what it used to be), the defrost cycl...
	RE: Electricity price predictions By EtchedPixels, 2 weeks ago Forum Electricity, Tariffs, Monitoring, Electrics & Providers
	2. As EV ownershp increases it'll certainly increase demand but most electric cars don't travel far in a day. It's electric trucking that is really going to matter not cars. Trucks use more kWh, opera...
	RE: Electricity price predictions By Transparent, 2 weeks ago Forum Electricity, Tariffs, Monitoring, Electrics & Providers
	For how long do you think that will be the case? 1: The electricity generation mix at night is different. There's no solar, but there's considerably more from gas-turbine plants.Because NESO have been...
	RE: Electricity price predictions By Batpred, 2 weeks ago Forum Electricity, Tariffs, Monitoring, Electrics & Providers
	Not many people consume overnight, so as a principle it is a safe bet… Probably the reason Octopus does not bother if Go users have an EV.
	RE: Valliant EnergyPlus By Batpred, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I meant to say I cannot register my kit at Energyplus… Solis also has AI, I tried it six months ago but it was overkill for my needs. It does read the tariffs, etc. To be honest, I cannot see why ML...
	RE: Minimum system volume By JamesPa, 2 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	I agree with your analysis from the physics standpoint. With ufh in slab the slab is going to provide a larger reservoir than the water. I guess the only other question is the dynamics ie does the ...
	RE: Minimum system volume By Tony.Stolz, 2 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@old_scientist Thanks for the reply. I am looking at this question from the perspective of physics. My system will be open loop with two large heat exchangers including a 1200 sq foot hydronic slab ...
	RE: Valliant EnergyPlus By L8Again, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	How can they stop anybody from signing up to a heat pump tariff. Powerwall owners also have AI-optimised solar and battery import and export. For all my solar is exported at 12p /kWh. This confuses En...
	RE: Valliant EnergyPlus By Batpred, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	For some odd reason I cannot even register for that. The Q&A makes very clear that it is a dedicated energy management system and no other system can be used alongside it. I am more interested to...
