What happens to a boiler if the water is turned off?
People often worry that turning off their water supply will adversely affect their boiler. The worry is usually caused by a fear of overheating, like boiling a kettle with no water in it, but in reality, it’s unlikely to cause any damage or risk.
Should I turn off boiler if water is off?
Turning the water off is fine. Unless your heating system has leaks the water to the boiler never needs to be turned on once it’s been properly filled & pressurized. Even if it has minor seepage at the vents or something it won’t lose enough in a week to matter.
Why does my boiler leak when I turn it off?
The most obvious reason for this would be that you’ve turned off the heating. When a heating system is on, you’ll see the pressure gauge creep up. Heat creates extra pressure. When you turn off the boiler and the system cools down, the pressure reduces and the leak stops.

Is it worth shutting down an electric boiler?
However, it may be worthwhile to shut down a modern boiler that uses an electronic ignition system. The water in the boiler will start to gradually lose heat to the outside air, no matter how well insulated the tank is. This may cause the boiler to come back on and waste energy.
