First class central heating and boiler services in Bexleyheath and Sidcup

At Abtek we are experts in boiler servicing, from boiler repairs, to boiler installations and boiler replacements. Since your boiler forms the hub of your home’s central heating unit, it’s only natural that we extend our boiler services in Sidcup, Bexleyheath and surrounding areas to include that as well.

What we can do for you

It may be that you have recently had your boiler serviced and everything is running okay, or that your domestic hot water supply is piping hot, but your radiators simply won’t warm up. In these situations it is not normally the boiler (replacement or new installation) that is at fault, but the array of pipes and radiators that make up your central heating system. There can be a number of reasons for this and, as the premier boiler servicing firm in the Sidcup Bexleyheath area, we can usually resolve them.

Cold radiators

If, following a boiler servicing, a boiler repair, or a boiler installation, your radiators aren’t getting hot enough, we would normally check the radiators and pipes themselves. Common causes for this problem include air in the radiators that needs to be released (known as ‘bleeding’ the radiators), or a build-up of sludge in the pipes that prevents hot water from your new boiler installation or boiler replacement from getting into the radiators. This can usually be flushed out of the system, or (depending on the severity of the problem) require a replacement pipe.

Power flushing

One of the boiler services we provide, along with boiler replacements and boiler repairs, is power flushing your central heating system. Less dramatic than it sounds, it involves ejecting the sludge and grime from your system, replacing it with fresh, clean water that will heat up nicely.


As well as boiler repairs, boiler replacements, and boiler installations, one of the other boiler services we offer is fixing thermostats. We have experience both with manual thermostats and modern smart thermostats (both hive and nest varieties) so your system is in good hands.
