Old wives' tale or hard fact? Our friends at the Centre for Sustainable Energy (CSE) have decided to explode a few myths regarding some well-meaning energy-saving advice which is supposedly meant to save us money but which, in fact, could end up costing us more. Here goes...

Leave the hot water heater on all the time, rather than turn it on and off
Myth: As long as the tank is well insulated, it should keep the water hot all day, without needing to be reheated. Modern washing machines, dishwashers and electric showers take cold water and heat it themselves so you don’t need a supply of hot water waiting in the tank.

If I turn all the radiators down low, I’ll save money
Actually this one is true – BUT only if you also turn your thermostat down at the same time. If you turn your radiators down low but still have the thermostat set to 21ºC, your boiler will keep running until the room temperature reaches 21ºC – and this will take a long time with the radiators on low. So if you want to save money and are comfortable with your house a little cooler, make sure you turn down the thermostat, not just the radiators.

You should leave the heating on all day,rather than turn it on and off
Myth: Why pay for heat that you’re not using? Even if you turn your thermostat down a little, your boiler will keep firing up and using energy.

Turning the thermostat up will heat the house up faster
Myth: If you come home to a cold house, it’s tempting to turn the thermostat up as far as it will go in the hope that this will somehow make the place warm up faster. Sadly this doesn't work. Your boiler will just carry on working at the same constant speed and your room will still reach it's normal temperature at the usual time and of course, there's always the possibility that you'll forget to turn it back until the house becomes like a sauna and you've wasted all that energy.

...and there are lot's more from CSE, with all sorts of expert practical advice, which we've found both helpful and surprising and you can read more about it here. You should also check out the DECC website which also helps clear up some common 'energy saving' myths and which also has some useful links and of course there's our favourites at theEnergy Savings Trust, the font of all knowledge when it comes to cutting your energy costs.
