	RE: Vaillant aroTherm not heating with many faults By Mars, 11 hours ago Forum Air Source Heat Pumps (ASHPs)
	I love it, and quite honestly this such great advice @jamespa… if you have an obscure error or fault code on your heat pumps control panel, irrespective of what the manual says it might or might not b...
	RE: Post-Traumatic Heat Pump Stress Disorder By Mars, 11 hours ago Forum Government Schemes, Regulations, Training, Planning & Organisations
	I find the timing of my latest video and this post oddly fortuitous (it was never planned like this) because it loosely collides directly with something I said repeatedly throughout 2024/25, especiall...

	@bash you and me both, can agree. Nothing like shooting yourself in the foot. Common sense would tell you that someone with the wherewithal to build a property, would have an eye for detail, and plu...
	RE: Experience - New Build / Complete New Heating System By Bash, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	@vincro We have a similar sized 1950's semi with a 2005 extension, lots of glass and an open fireplace. Our heat loss was calculated at 6.2kw and testing this before our HP install later this month b...
	RE: Heat loss based on gas usage By Bash, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa Thanks. The numbers posted above were just for the coldest day over the last few weeks. Looking through the bright app it's similar across many days over the last few weeks suggesting it's n...
	RE: Experience - New Build / Complete New Heating System By vincro, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I would wholeheartedly agree with you. In all the videos of @editor, I never recalled anyone talking about such HUGE pumps. Certainly a rarity rather than the norm. It was one of a few red ...

	RE: Experience - New Build / Complete New Heating System By JamesPa, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	Newbuild 200sq m house, 16kW? Somebody is having a laugh at your considerable expense. Either the construction standard is appalling or the loss is way out. My 1930s 200sq m house with partial iwi o...
	RE: Heat pump not reaching flow temperature By JamesPa, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	I would describe this as either a fault or a configuration error. If the ft isn't changing with oat then wc isn't working, your heat pump won't be efficient, and you won't be comfortable. The instal...
	RE: I’m glad the cold spell is over! By Mars, 13 hours ago Forum Your Home
	Thanks for the update, @judith. Cold spells with heat pumps can be brutal, especially with the price of electricity, but thankfully those extremes tend to be short-lived in the UK. I remember a spell ...
	Heat loss based on gas usage By Bash, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	We are 2 weeks away from our HP install. In October I dropped the flow rate down on our Vaillant gas boiler to 45c, to match our HP design temperature. We are upgrading all the radiators as some are w...
