It will keep the water hot as long as the electricity or gas is on. If it's going to be off more than a day, turn the breaker or gas valve off.

Reason for question: Plumber left valve open and flooded house The hot water (heater) tank is fed from a 'header tank'; normally in the loft space but can be combined with the main heater tank (fortic).
