Just be careful with electric showers some don’t like being on for extended periods of time. But yes the more electricity you burn the lower your bill. Put your oven on that’s a good one, run a boil wash thru your washing machine as that’ll clean it if bacteria too. If you have an immersion heater use that during the period etc
thanks for that, I’ll put the shower on for a couple 10 minute blasts and everything else on you suggest 🙂
