	RE: Radiator sizing for heat pump installation by British Gas - are these correct? By Bash, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa After months of research, that is my understanding, that you ideally don't want to remove a radiator from the system completely (the trv switching it off), as you want to keep as much of the...
	RE: Radiator sizing for heat pump installation by British Gas - are these correct? By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Trvs switch the flow off altogether so anything which reduces flow rather than switching it off is better from a flow perspective. Frvs are as you say sold to help with balancing. However given what ...
	RE: Heat Pump Installers: Competence, Illusion and the Hard Truth Homeowners Must Face By Mars, 4 weeks ago Forum Government Schemes, Regulations, Planning & Organisations
	@fiona everything you’ve said resonates with what we hear from so many homeowners. Please be careful with the installer who’s offered to “make a difference” or fix your system. We recently had that ex...
	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By AgentGeorge, 4 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	@grahamf I had a similar journey, had 2 people do heat loss calculations. The first was very professional and looked at solar gain for each south facing room, as my house is EW facing. The second sur...
	RE: Heat Pump Installers: Competence, Illusion and the Hard Truth Homeowners Must Face By Fiona, 4 weeks ago Forum Government Schemes, Regulations, Planning & Organisations
	Thanks both for your responses. We have paid for an independent report (the warranty company asked for this) to ascertain what’s wrong with the system. There appear to be a number of issues the bigges...

	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By GrahamF, 4 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	@jamespa unfortunately, I don't think heat loss calculations can ever be terribly accurate. Our house was built in 1968 and has a real hotchpotch of different floor types. A few walls have different...
	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Batpred, 4 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	Just wondering, and maybe this is a bit of a curve ball... All these heat loss calculations may make sense on a new home but would it take much more than someone sticking a few temperature sensors ar...

	Or nuclear fusion.. But what is proven (reservoirs, batteries, etc) can still go a long way..
	RE: Renewables & Heat Pumps in the News By Batpred, 4 weeks ago Forum Well & Truly Off The Grid
	I am not sure if many people would be running aircon or similar high powered devices, relying on PV and the grid.. i assume they would not keep a system that would trip frequently going. Even with a b...
	RE: What crazy nonsense are inverter limits and why are they imposed? By Transparent, 4 weeks ago Forum Energy Storage
	That will be producing significant losses due to phase imbalance at the local substation. I cannot understand why SSES would be prepared to tolerate that.It's clearly not "grid friendly". SSES ...
	RE: Renewables & Heat Pumps in the News By Transparent, 4 weeks ago Forum Well & Truly Off The Grid
	Erm... seeing this from an electronics viewpoint, you can't have two entirely separate control channels implemented on a commercial inverter by anything other that it being deliberate! Slackness can't...
