How can I insulate my hot water tank?
You can buy a jacket for your hot water tank from your local DIY store. This is one of the simplest and cheapest things you can do to cut your fuel bills and save energy. Some cylinders already have foam sprayed on them don’t need a jacket. It’s also worth insulating the pipes that enter and leave the tank, you can get foam tubes to do this.
What controls the temperature of my hot water?
Hot water storage tanks are usually fitted with a thermostat to control the water temperature. For water that’s heated by an electric immersion, the thermostat is inside the tank. If you heat your water with a combination (combi) boiler, the water heating control is on the boiler.
At what temperature should the tanks thermostat be set?
The temperature you set determines the temperature of the hot water coming out of the hot water taps. Ideally, it should be set to 60°C and definitely no lower than 55°C (as this could cause legionnaires disease).
