Smart Hot Water Tanks
Are a great way to improve your hot water energy efficiency – they can save you £ and CO2 as they only heat up the water you need and can heat much faster.
If you are changing your hot water tank these can work with existing heat sources, such as electricity, gas or oil, and can also be used with heat pumps. You could even fit now with existing hot water heating and upgrade them to work with a heat pump later.
