Glad to hear I’m not the only one, you got me thinking about measuring the temperature of our hot water to see what discernible difference it make between 45 and 40, the boiler literally next to the sink and the bathroom is on the right so don’t think it’ll lose heat from that distance.
We managed to keep the gas bill to under £28 last month with the boiler at 50 degrees, hopefully it’ll reduce it a bit at 45.
Thank for the advice!
