What's a Chemical Flush and When Should I Get One?

If you’ve got a heating system that uses hot water to heat your home, you’ll probably need a chemical flush at some point. This is because sludge and debris naturally builds up in heating systems over time, and needs removing.

If you’re not sure what a chemical flush is, you’re in the right place. Keep reading to find out how a chemical flush works and when you might need to get one.

What’s a chemical flush?

A chemical flush uses a mixture of chemicals and water to clean out your heating system. The chemicals dislodge and break down the sludge and dirt that builds up in your pipes and radiators. This makes sure that hot water can get through to all the different parts of your heating system and warm your home effectively.

It’s best to hire a professional to perform a chemical flush on your heating system, as it can be a tricky job. They’ll need to drain and refill your system, and flush it through to make sure they’ve removed all the debris. Heating systems can be delicate, so need careful servicing and maintenance.

When should I get a chemical flush?

There are several signs that your heating system might need a chemical flush. Banging or clunking noises coming from your pipes or radiators could indicate that there’s sludge in them that needs removing. Or if your radiators don’t heat up properly or consistently that could also be a sign.

It’s also a good idea to flush your heating system before you get a new boiler. This will help to make sure that your boiler and heating system works efficiently and lasts for as long as possible.

We want to help you make sure that your new boiler’s here to stay. That’s why all our boilers come with a free chemical flush and filter before installation. This will help you get your boiler off to the best possible start.

What’s the difference between a chemical flush and a power flush?

A power flush uses high-pressure water to clean your heating system, whereas a chemical flush doesn’t. A power flush is generally better at dislodging heavy sludge deposits or debris, but is usually more disruptive than a chemical flush. So, unless your system is seriously dirty, a chemical flush tends to be the better option.

Sometimes people choose to go for a chemical flush over a power flush because the high-pressure water can damage delicate or old plumbing systems.

So, if your heating system isn’t working properly or you’re buying a new boiler, a chemical flush might be what you need. Speak to a professional to make sure you do the best thing for your boiler and heating system.
