Is your water temperature, like British heavy metal band UFO, too hot to handle? When you turn on the hot water at your sink and wash the day off your face, do you have to turn the cold water on just a teensy bit, too?
If you answered yes, your central heating boiler is working harder than it needs to, and you’re wasting money and energy.
