May 23, 20215 yr 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 UncleK
May 23, 20215 yr Airtightness and insulation, then you can probably swap the GSHP to a much cheaper ASHP. And look at your DHW usage, water does not need to be stored above 60°C all the the time and a shower does not need to use 150 litres of water
May 24, 20215 yr Author Hi SteamyTea, Thanks for that. We are indeed working on insulation although we have already committed to the GSHP. Anything on power import and export welcome :). Cheers Alun Edited May 24, 20215 yr by UncleK

May 24, 20215 yr Author Sorry - my apologies. I should have typed in full - I meant Photovoltaics, so solar panels. Sorry about that Cheers UncleK
May 24, 20215 yr You can go to https://ec.europa.eu/jrc/en/pvgis And get a fairly good estimate of output. Think there is weather info there, but the Met Office now has lots you can download for free (after I paid hundreds to get some).
May 24, 20215 yr Author Yes thanks - I'm hoping we can get 10 or 11 kW when running at full tilt. Cheers UncleK
