I just turned my flow rate and rad temps back up. We lowered them and found we had to have the heating on all the time to try and warm the house.
My running hot water temp is reduced to 50
Flow rate of heating 70 degs
Rad temp 65 degs
We burn leccy more, TV's, devices, lights, air frier, electric cooker, washing machine, tumbler,, shower.
Central heating / water is our only gas.
They are trying to get my DD to £300 a month. A year ago it was £112.00
