Hi,
We had our boiler and hot water tank replaced a year ago and at the same time got dual controls and rad valves. I was always told that with a separate hot water and heating function, it was cheaper to heat water by the gas boiler rather than the electric immersion and just wondered if this was actually true?
Thanks
