In the peak summer when you are in excess couldn't you pump heat back in to the ground via your ground loops to give you a net benefit delta T for winter or is that some nonsense I picked up some time back when ground source heat pumps were the big new thing ?

You can have SEG with an octopus EV tariff but its a much lower payout, circa 4.1p / kWh.richbee wrote: ↑Tue May 23, 2023 8:38 amIs that the case - no SEG with Octopus smart tariffs, or is it only Go?
I assumed that any Octopus smart tariff would also be able to provide SEG.
I'm planning to swap to Octopus to take advantage of cheap rate battery charging in Autumn / Winter, but I currently still export using SEG due to no EV or heat pump or hot water cylinder

That's fair enough, I'm only on 5p now with So Energy - I understand they can't pay out top dollar for unreliable spare capacity at the same time as everyone else has spare PVnowty wrote: ↑Tue May 23, 2023 10:37 amYou can have SEG with an octopus EV tariff but its a much lower payout, circa 4.1p / kWh.richbee wrote: ↑Tue May 23, 2023 8:38 amIs that the case - no SEG with Octopus smart tariffs, or is it only Go?

As my heat source for my GSHP is a river the heat would end up in the sea.Andy wrote: ↑Tue May 23, 2023 7:53 pmAll the studies I have come to the conclusion it isn't really worth doing.Moxi wrote: ↑Tue May 23, 2023 10:29 am MM

Quite a turnaround now, had another all time best of 35.9kWh yesterday, beating April by 4kWh per day on average, and currently 1kWh per day above PVGIS estimate, with good weather forecast for the next couple of weeks

Re: Mental May
Similar here, its been a very consistent May apart from 2 poor days earlier in the month.
And the forecast shows no end of sun with some decent temperatures.
Its payback for the shocking March,
