1. Get a boiler service annually

You should have your boiler serviced every single year by a qualified heating engineer or plumber. They will be able to identify and minor issues with your boiler that could grow into bigger problems – shortening you boilers life and requiring you to purchase a new one prematurely. An engineer will also be able to spot any potential risks from carbon monoxide, although you should always have a working carbon monoxide in your home if you have a gas boiler.

2. Run your heating in the summer

Many households turn their boiler off over the summer months to cut costs and ensure their home is not overheated. This is a great way to save energy but turning a boiler off for a long period of time can cause parts to seize up when it is turned back on. To prevent this, make sure to switch your boiler back on a few times over the summer to run the heating and hot water for a short burst.

3. Prevent frozen pipes in winter

Frozen pipes can cause a lot of damage not only to your heating system but also the area of your home they burst in. You can however take preventative measures, which is especially beneficial for peace of mind if you are away from your property in the colder months. Setting your thermostat so that your heating stays on low whilst you are out, or so that it switches on occasionally can help. You can also add insulation to your pipes – this can be purchased in DIY stores and is cheap and easy to install.

4. Bleed your radiators

If your radiators aren’t heating up properly, you may need to bleed them. Bleeding radiators releases trapped air which can prevent them from filling correctly, keeping part or all of the radiator cold. Ensuring your radiators are heating efficiently means putting less strain on your boiler. You should check your boiler pressure after bleeding radiators in your home to ensure it has not become too low – if it has you can simply top it up again using a filling loop.

5. Have your central heating system powerflushed

A powerflush is a cleaning process which involves a heating engineer using a pumping unit to distribute a cleaning solution through your heating system to remove sludge, rust and other deposits. Generally a powerflush is required when you have a new condensing boiler installed but can also be performed to help remedy noisy boilers and pumps, cold radiators and other symptoms of build-up in the system. Having your heating system powerflushed can be slightly costly (usually between £350 and £1200) but it is worth doing if it will extend the life of your boiler.
