How do you clean and maintain your heating system?

November 9, 2021

Your heating system must be clean, especially when you have invested a new boiler installed, you wouldn’t have a new car with the old engine oil in it so why do the same to your homes new engine?

When the water that flows around your heating system gets dirty, it will damage the boiler and radiators, increasing fuel bills and potentially VOID YOUR BOILER WARRANTY. Systems get dirty when air is introduced to the system, for example, when we top up the pressure on our boilers. There are several very effective measures available to clean your system and keep it clean. The best actions arealways preventative, i.e. having a clean system and using magnetic filter and deaerator.


A new flushing process designed to maintain and protect your central heating systems from the damaging effects of iron oxide sludge buildup. Its a small unit with two magnetic filters built-in which catch any system debris that has formed within the heating system.


A process by which a purpose-built machine pumps chemically treated water through your radiators and pipes at high speed to clear a buildup of corroded metal and scale. In severe cases, the deposits can cause blockages that stop radiators from getting warm, increasefuel bills and damage the boiler.


A scale filter is a compact device fitted below the boiler on the cold water main supply pipe. It helps to reduce limescale within the boiler and is particularly useful in hard water areas.


These filters remove sludge from the system as it passes through the magnet. They are an excellent device for protecting the boiler from any sludge in the system and when paired with a deaerator, they ensure a clean and efficient heating system for the long term.


Small devices, about the same size and cost as a magnetic filter that removes air from the system and keeps it clean on anongoing basis. This is the best form of prevention for sludge.


Once we have flushed and are happy with the system cleanliness, we add a premium-grade chemical called an inhibitor.

Corrosion inhibitors, otherwise known as Corrosion Protectors or central heating inhibitors, safeguard the central heating systems against the formation of sludge and scale buildup. The damaging effects of corrosion debris can cause boiler noise, radiator or pipework blockages and boiler breakdown, and negatively impacting overall system efficiency.


Finally, once we are happy that your heating system is cleaned and chemically dosed, we will issue you a certificate to confirm our engineers test results. More importantly, it gives you the confidence to know that the installation will be hassle-free from any warranty issues.

We advise that you get your boiler checked by one of our professionals as soon as possible. Get a quote for a boiler service today!
