Just wondering can a modern gas boiler heat water for showers, etc more efficiently than turning on the immersion a couple of times a day.
We have what I think is fairly common boiler (Gloworm Flexicom 24hx) for 4 bed house. Is it possible to turn off the radiator heating and just heat water using the boiler and am I correct in thinking that just turning off all the radiators is inefficient.
