We’ve all heard them: from leaving the heating on low all day to turning the thermostat up high to heat the house more quickly. Saving energy is important for the environment and your finances, but are these age-old techniques actually doing more harm than good?
I can save energy by not switching off my chargers, radiators, heating pumps and water tank, can’t I?
Some claim that always leaving the heating on low instead of turning it on and off on demand uses less energy, because you’re keeping your home at a constant temperature rather than heating it from cold. But why pay out for a cosy warm house when you’re not in? Switching on the heating when you need it is far more cost-effective.
The same myth exists with immersion water heaters and is equally costly. Heating water only when needed, checking you have energy-efficient heating pumps and ensuring that your tank is well insulated are all ways to save money and energy. Grundfos heating pumps are ‘A’-rated for energy efficiency, which could help you spend less – and protect the environment too.
Even your device chargers should be switched off when you’re not using them. Mobile and laptop chargers consume energy even if no device is connected. Over 90% of the electricity used by chargers in the UK is wasted, so do yourself a favour – if you’re not using it, unplug it.
How about turning it up? If it’s faster, it’ll save time and money, won’t it?
It seems to make sense – by turning the thermostat up, your house will heat faster, so you’ll be using energy for a shorter amount of time. Unfortunately, this is another myth. Boilers heat up at the same rate no matter what the thermostat is set to.
However, some brands, such as Grundfos heating pumps, have a ‘variable speed’ feature allowing them work faster when needed, potentially saving energy and money.
Other people claim using a portable electric heater to heat a room quickly is more efficient than waiting for the pump to circulate hot water through the whole house. This may be quick, but electric heaters are one of the most expensive ways to heat a room. Wait for your pump to do the work and you’ll thank yourself later.
What if I wait until the evening to use electricity? It’s cheaper at night, isn’t it?
This depends. Electricity can be cheaper in the evening if you’re on an Economy 7 tariff, but most of us are not and are charged at a flat rate for each unit of electricity used.
However, you can save electricity not only by following the above tips, but also by making sure you switch off idle computers, televisions and so on. Computer monitors are especially energy-hungry, so turn them off to save.
Last but not least, some people argue that they’re saving money by not buying more expensive energy-saving devices – the cost of which outweighs the savings they bring. These appliances might be more costly, but the money and power saved throughout the product life is far greater. We offer a variety of highly energy efficient pumps to help you save more and use less.
