    Some top tips for saving on your hot-water bill.

    Water heating is about a third of household energy use. So if you want to reduce your power bill, hot-water use is a good place to start. If you do it right and target the hot water that just gets wasted, the only difference you should notice is your energy bill shrinking.

    We also explain the types of systems available, their advantages and drawbacks.
