Water treatment for heating systems falls into two categories:
– Cold water feed to combi boilers or hot water cylinders primarily limescale protection
– Heating system water quality
Cold water feed treatments
In areas of hard water it is critical to protect your new/existing boiler or heating system from limescale damage. Limescale will quickly effect the performance of hot water production from a combi boiler or cause irreparable damage to hot water cylinders. Limescale will also build up on taps, inside shower mixer units and stain shower screens and sanitary ware.
Limescale protection comes in various types each with different levels of effectiveness and advantages/disadvantages.
Water Softeners – A water softener is an electrical/mechanical unit which removes the chemicals in hard water areas which cause scaling: calcium and magnesium carbonate. These devices turn hard water to soft water.
Scale Prevention – These prevent these chemicals (calcium and magnesium carbonate) depositing themselves inside pipes, tanks, combi boilers and shower heads. These are small plumbed-in devices that use chemical, electrolytic or magnetic methods to accomplish this.
Water Filter – these remove bacteria, chlorine, pesticide residues etc. These mostly come in the form of plumbed in filters, handheld filter jugs with disposable cartridges for potable use or reverse osmosis which produces pure water having removed all particles and chemicals.

Heating System Protection
Best advice is to ensure that the system water is clean and properly treated before a new boiler is installed. Boiler manufacturers will check the water quality in the heating system if they are called out to a warranty repair and they suspect the cause of the breakdown is due to the water quality. If the water quality is found to be below recognised standards than the boiler guarantee will be invalidated.
Before installing a new boiler the central heating system needs to be cleaned via a power flush or a system cleanse. This will remove all the debris and sludge from the radiators and pipe work which would otherwise go through your boiler and damage it’s performance.
To provide further protection a system filter is added to the boiler heating return pipe which will collect any debris thus preventing it from getting into the boiler.
Heating System Power Flush
Before installing a new boiler the central heating system needs to be cleaned via a power flush or a system cleanse. This will remove all the debris and sludge from the radiators and pipe work which would otherwise go through your boiler and damage its performance.
Over time central heating system water accumulates harmful dirt and debris such as rust and solder fragments shed from older radiators and boilers plus limescale deposits all of which can cause considerable problems for the heating system as a whole as well as the boiler itself.
It’s highly recommended that a Worcester Greenstar System filter is installed on your boiler heating return pipe which will prevent magnetite build up within the boiler by filtering out all the debris and dirt before it causes damage and radiator blockages.
These filters are extremely easy to maintain which ensure the smooth running and optimum efficiency of your heating system.
In addition to the above we are able to supply an install a range of accessories to maximise the efficiency of your system including flue gas heat recovery units, new radiators and many more.
