Hi I have a hot water tank heated by gas. The only control is a knob that turns the gas off and sets the temperature. So if I want to stop heating the water I have to go to the cupboard and turn it off. It is designed so that the water is kept hot all the time. So should I turn the water off at night and turn it on in the morning or leave it as it is? I.e will it make any significant savings?
Thanks Tricia
