@icanbob ..price power and the modest level of solar at this latitude. That won’t make it free but the credit from exporting the spillover from late March to mid October will further offset the annual cost. I’m aiming for £2-300 as the annual energy bill, compared with £1000-£1200pa with the old gas CH system. I’ve already got the granular data on the heat pump from Jan till now and with a couple of months with solar+battery I’ll have sufficient for a clearer estimate.
