Powerflush

A Powerflush (or power flush) is an efficient way of removing the sludge and dirt that build up inside your central heating system over time. Without a Powerflush you could see a gradual reduction in efficiency of your boiler system as this sludge coats the internal piping and reduces circulating efficiency.
Most central heating systems [...]


Heating controls

The heating controls in your central heating system are designed to allow you to control the temperature of your home and to use energy efficiently. For the controls to be effective you should be able to turn them on and off and they should rapidly react to any changes in room temperature. If you have [...]


Carbon Monoxide

Carbon monoxide is a very poisonous gas with no taste, no colour and no smell. It can be produced by a boiler when there is insufficient oxygen in the air supply to the combustion chamber. The lack of oxygen means that Carbon Monoxide is produced rather than the less dangerous Carbon Dioxide.
With high standards of [...]


Check Ventilation

When your central heating system is installed the installer should have carried out a survey to ensure that there was sufficient working ventilation to the boiler. Modern boilers are very safe provided that proper care and attention has been paid to the ventilation in the room and that the boiler is serviced regularly.
There are [...]

Without care and ongoing maintenance your new central heating system will gradually deteriorate over time as impurities build up within the circulating water.
There are products on the market which help to reduce the effects of corrosion and the build up of scale or sludge within your central heating system. These are often applied annually or [...]


Repressurise your Heating System

Most combination boilers and many standard boilers are now installed as Pressurised Systems. This differs from the previous conventional boiler systems which were reliant on a water tank (often in the loft) with a ball float device to maintain water levels within the system. As the self filling water tank is omitted a [...]


Bleed a Radiator

If the top of your radiator is cold and the bottom is warm it probably means that the radiator needs bleeding. If you want to check this take care to not burn your hand on the radiator.
If the radiator is almost full of air, no difference in temperature between the top and bottom of the [...]
