I have updated the Evohome firmware to the latest version, but I cannot see how it changes how the heat pump is controlled. I would be very interested to hear how others have integrated Evohome with a heat pump. Previously we used 3,500 litres of oil and around 8,000 kWh of electricity p.a. (we have an EV and pre Covid we did around 25,000 miles pa in it). We are now using 18k/19k kWh of electricity pa (yes, we are probably melting the grid!). Solar is very difficult because of the layout of the building and we are in a prominent position in the centre of a conservation area.
