	RE: Heat Batteries By Batpred, 3 weeks ago Forum Wood Burners, Biomass, Small Scale, Biofuels & Other Heating Alternatives
	Yes, you make a good point and beyond servers, engineers use whole platforms and open protocols, at least for common devices. So if their app stops working or you prefer another app, it often works as...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Which is logical, albeit 30l is a bit small. The manual it seems is clear which trumps anything the installer says and TBH anything the grant helpline says unless they also confirm that the manual is ...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Thanks JamesPa, Sorry for my lack of understanding on terms/2 port v 4 port etc. Just unsure then why the installer insists on this LLH if the manual doesn't seem to state one is required. It just see...
	RE: New Fogstar 15.5kWh upright solution By Batpred, 3 weeks ago Forum Energy Storage
	Fair enough. I am not aware how this Solis (2in @transparent post) works internally, but one way to think about it is if the internal oscillator continuously sets the frequency of all the AC that the...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Volumiser totally different to buffer or llh. Volumiser 2 ports, buffer/llh 4, volumiser doesn't cause system distortion, doesn't penalise COP, buffer/llh does. Either solves defrost issues and miti...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Not sure then, I’ve been reading the manual and it does state it needs a volumiser, and even suggests options for low volume systems (why they didn’t think to go with that I don’t know). However havin...
	RE: Isolating the system for a planned power cut By Batpred, 3 weeks ago Forum Solar Photovoltaic (PV)
	Insurance helps and when adding high powered devices like EV chargers, PV panels and some inverters and heatpumps, the other circuits may need to be a bit more shielded, and future proofing is also wo...
	RE: New Fogstar 15.5kWh upright solution By Transparent, 3 weeks ago Forum Energy Storage
	I'm finding it difficult to follow your descriptions. There are two different classes of grid-tied inverter: 1: Those which synchronise to the 50Hz grid frequency. 2: Those which have their own intern...
	RE: Isolating the system for a planned power cut By Transparent, 3 weeks ago Forum Solar Photovoltaic (PV)
	That's correct. I was mentioning it as something which would be a future requirement. Both arc-detection and surge suppression devices (SPD) are like paying an insurance package.Even if you decide not...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	R290 has an explicit installer setting for 'no buffer'. It couldn't be clearer!
	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	A quick google states the Grant Aerona3 requires a low loss header as a mechanical break as part of Grant’s install package - I suspect they’re using the install package and not opting to not have the...
	RE: Isolating the system for a planned power cut By Batpred, 3 weeks ago Forum Solar Photovoltaic (PV)
	Bu the way, my understanding is that arcing detection is not required for new circuits unless it is a shared use property? Or is it only for rental properties? As for SPD protection, for the extra £20...
