Hi recently moved into a new (to me built 1990) house and the hot water is heated by gas and the heating is by gas hot air. It is manufactured by Johnston and Starley. The only control for the water heating is a thermostat control on the boiler. There is no timer etc. In fact if the electricity is off the water is still heated but the hot air heating stops. So the only way to control the hot water is by the thermostat in the heating unit. The question is, is it more energy efficient(save money on the gas) to leave the hot water on all the time, as it seems that is how the system works, or manually turn the hot water heating off and on when necessary? However turning it off and on requires planning as I get up in the morning and go straight into the shower so I would have to get up a bit earlier or have a cup of coffee while I waited on the water heating or would it be hot enough. Also I may get used to it but while lying in my bed I keep hearing the gas coming on for a few minutes then going off again as it keeps heating the water. There are only 2 adults in the house. So what are the opinions of the DIY fratenity?
