How to keep your boiler at its best

Now summer is here we tend to spend less time thinking about heating our home and our boiler and more time thinking about enjoying the sunshine and getting outdoors.  

However, it’s important to remember many of us rely on our boiler throughout the year to ensure we have hot water (which you’ll need even for cooler summer showers). And, that now is also a good time to take action to help ensure your boiler will work efficiently when you need to heat your home again later in the year.

Here are five things you should consider to keep your boiler working at its best all year round.

1. Get it serviced

Whether you already have a high efficiency condensing boiler or an older boiler, one of the most important things you can do is to get it serviced at least once a year. This will ensure it runs efficiently and smoothly for years to come. Rather than waiting for something to go wrong and paying premium prices for repairs, servicing your boiler regularly can help you identify any issues early and prevent costly repairs down the road. A typical boiler service can cost between £80-£1001, but if you have boiler cover its worth checking as some companies who offer boiler cover do also include an annual service.

2. Upgrade your boiler

The efficiency levels of boilers in the UK are determined by measuring how much fuel is converted into energy that is used (and not wasted). All modern gas boilers are condensing boilers, which are more efficient because they can capture energy from condensed water vapour2 and recover more heat, requiring less fuel to run.

If you don't already have a condensing boiler, summer is the perfect time to consider upgrading to a new boiler that is more energy efficient because you aren’t relying on your boiler as much for your central heating in your home.

As well as being more energy efficient, condensing boilers are cheaper to run. So, depending on the boiler you have, you could save around £205 a year3 by upgrading your boiler.

3. Add an insulation jacket

If you have a boiler with a water tank, adding an insulation jacket could save you around £80 a year4. A jacket costs around £154 and improves the efficiency of your system by reducing the heat that can escape through its walls. This means that the water in the tank stays hot for longer periods of time, which means you need to use less gas to re-heat the water you’re using.

4. Upgrade the controls

Ensuring you have the most appropriate controls for your boiler system can improve the efficiency of your boiler. Your system controls should include a boiler thermostat, a timer or programmer, a room thermostat and thermostatic radiator valves (TRVs)5.

By using a programmer, you can set your system to turn off automatically when you're not at home or after you've gone to bed. In addition, using smart heating controls, such as tado°, allow you to make adjustments from anywhere with your smartphone, computer, or tablet. Many smart thermostats can learn from your habits and automatically adjust the thermostat for you, making saving energy even easier.

5. Schedule a powerflush or use chemical inhibitors

Over time, rust and sludge can build up in your central heating system and reduce the effectiveness of your radiators and the efficiency of your system. Some engineers recommend scheduling a powerflush for your central heating system every five years, which can cost between £275 and £6506, depending on the number of radiators in your home. A preventative option is to use chemical inhibitors7 to decrease corrosion, prevent the build-up of sludge and scale, and help keep your system running efficiently.

So, whether you are considering buying a new boiler or you are happy your boiler is meeting your needs and is as energy efficient as possible, now is the ideal time to give it some much needed TLC.
