Never been past end of October without the gas boiler back on, at least in the peak leccy hours so in that way its a record. And there is almost no doubt my personal best will be achieved, i.e. less than 4,009 kWh of gas in a 12 month period subject to the heat pump not having a catastrophic failure.
But whether I beat my personal pledge target of less than 2000 kWh of gas from 1st May 2021 to 30th April 2022 is still open to question, especially if we really do have a prolonged cold spell later in the winter. And for example, I am off to my parents in the north later in the week and I will probably shut down the heatpump and turn back on the gas boiler for my absence.
I doubt SWMBO would be able to deal with a water pump failure !, I cannot imagine her on her hands and knees in the freezing cold with a torch and pair of pipe wrenches and me on the iphone talking her through it.
