Hi there.
We're upgrading our sixties house in Sussex with a GSHP, underfloor heating and a new hobby room (separate building) with a goodly chunk of solar PV to go onto its roof. The hobby room will have a separate ASHP. The insulation in the house has also been improved.
We've done most things in the house but the new hobby room is yet to be built (we have planning permission) and we're just at the stage of re-wiring the existing house. Octopus have installed a three phase smart meter, although we only have two phases to the house (and that ain't gonna change).
Stumbled across this site and wonderful forum when searching for how the importing and exporting of power is going to work with two phases, potentially phases both generating and using power.
Any experience or knowledge in that area gratefully received!
Cheers
