Never leave taps running to prevent freezing, with water charges becoming a fact of life it is better and cheaper too to insulate pipes and cold spaces instead
It is also advisable to have dripping taps repaired or replaced as well
Do not forget to insulate the water storage tank in the loft paying particular attention to the top of the tank (pvc lids are readily available if one is not already fitted)
Save on fuel by turning down the thermostat a notch or two.
Fitting thermostatic radiator valves, a room thermostat and a cylinder thermostat can drastically improve the efficiency of your heating and hot water system
If replacing a boiler, cylinder or any other plumbing/heating component it is always wise to choose high efficiency models
Similarly with showers, wcís and taps. There are eco-friendly versions of almost every plumbing and heating component available to us
