Morning Dan T You are collecting a lot more data than I am. But I think your plan to only heat when needed is sound. Else the ASHP only heats a bit,...
That’s a whole lot of expansion vessels - 3? I’ve got one for the Mixergy tank. And the Daikin has an internal one

Just seen your note Mars - what tweaks would you suggest? Ecobubl just departed, having sorted an issue with the Mixergy/Daikin not communicating. I...
Hi Kev, yes it’s the full demand for heat & h/w. I’m hoping the 7500kWh is a maximum, and the requirement will be less. Since the heat demand/loss...
