	RE: Surge Protection Devices By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	@transparent Thanks for confirming this.
	RE: Surge Protection Devices By Transparent, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	I don't believe it's in the Vaillant documentation. I can see no functional advantage in a heat-pump being supplied via an RCD. It's purely a protective device, and won't operate at all unless there i...
	RE: Configuring third party dongle for Ecodan local control By F1p, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	A few notable developments: I'm working through adding Air-to-Air support into my existing adapters, therefore one device will be compatible with all Mitsi's offerings. The device will detect the unit...
	RE: Vehicle-to-Home with a Heat Pump: Is the Technology Ready and Which EV Should I Buy? By Judith, 1 day ago Forum Energy Storage
	Vehicle to Grid is the further step and here is the IEA’s prediction on this (They are historically predicting on the slower side of what actually happened on things like solar generation)
	RE: Surge Protection Devices By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	I am not missing that, I assure you! I am trying (and failing) to find in Vailant's documentation, the underpinning for your statement: I reiterate that, whilst I agree with your final sentenc...

	The additional profit being made the installers.
	RE: Surge Protection Devices By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	I agree with your final sentence but where exactly in the Vaillant documentation does it say this. Neither my Vaillant documentation, nor the document @trebor12345 produced, requires an RCD at all. ...
	RE: Surge Protection Devices By Transparent, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	The issue isn't DC leakage. Type-B RCDs and RCBOs will trip correctly despite the waveform having a DC component present. You need the contacts to open when there is a genuine difference of 30mA or mo...
	RE: Renewables & Heat Pumps in the News By Jeff, 1 day ago Forum Renewables News
	Where the grid is heading? Input from Kraken.
	RE: Surge Protection Devices By Batpred, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I suggested to have a Contactum RCBO and the installer´s anxiety was very clear! Obviously the Hager CU is worth it, to avoid the emergency electricians that he had in the past. And not know...
	RE: Surge Protection Devices By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	@batpred of course you could just leave out the RCD altogether which is what my electrician did.
	RE: Say hello and introduce yourself By Singlespeed, 1 day ago Forum Introductions, Forum Rules & Updates
	@editor I watched some of the videos on Grahams heatpump channel and they look to be well put together. Importantly the controller seems to be a lot more user friendly than the Midea. However there do...
