Two boiler tricks to slash hundreds off your energy bill

Reduce your energy bill this winter with these simple tricks that you may not have thought of.

The government’s Energy Price Guarantee may have stopped energy bills rising by around 80%, but from 1 October, anyone on a standard variable tariff will have seen their bill go up by around 27%. 

To help households with rising costs, the government announced a £400 discount split over six months.

But, with news around shortages and rising costs, we’re all looking at ways to keep those bills as low as possible by avoiding putting on the heating for as long as possible

But did you know there are two simple boiler changes that could save you up to £25 a month on your energy bill? 

Here’s what you need to know.

Turn off your boiler’s preheat function

When the preheat function of your boiler is on, hot water is ready to go at all times – even when you’re not using it. 

By turning this function off you’ll have to wait a couple of minutes for the water to heat up, but it will shave anywhere between 5% to 10% off your energy bill.

Turn down your flow temperature

Combi boilers in the UK are typically set to around 80C, but this isn’t necessarily the most efficient temperature for a boiler to operate at, according to boiler experts. 

Lowering your boiler’s flow temperature will regulate the water temperature when it goes from your boiler to your radiator. A lot of heat escapes into the air during this process, so experts recommend you keep your flow temperature low, as this means less heat is lost as the boiler recycles the majority of the heat back into the water to heat it up. 

However this option is only available to those with a condensing combi boiler that is not connected to a hot water cylinder, where your hot water is stored. Experts say this tip could save people anywhere between 6% and 8% off their gas bills, and some could see their bills reduced by nearly £100. 

To safely turn your boiler’s flow temperature down, have a look at your boiler manual. If you’ve lost it you can type your boiler model into a search engine to get a PDF copy. The lower the temperature, the more efficient your boiler will be. 

It’s worth keeping in mind that turning your flow temperature down will mean your house will take a little longer to heat up, but you will be making savings on your energy bills.

A number of energy suppliers are recommending this move for households, including Octopus Energy. Octopus Energy said this is a little-known, but very effective tip for saving gas whilst staying warm. Its customers have reported saving over £100 on their bills.
