Hi,
We live in a newbuild and have a large hot water tank upstairs (santon premier plus unvented) with a control downstairs (Channelplus h27xl) to turn it (and the heating) on/off. The builder told us it's cheapest to leave it on all the time, but I'm not convinced - it seems to heat the water up to a very high temperature (which keeps upstairs really hot, even in summer) and we don't need boiling hot water, nor do we need hundreds of litres every day. We turned it off just to see how it would go on Fri, and as of Monday afternoon, we still have enough hot water. Any advice? Is it energy efficient to just turn on when needed? Or use the boost function ahead of planned use (i.e. baths/showers?) TIA for any advice!
