Why Power Flush Radiators
During the life of your commercial or residential central heating system, oxidation occurs. This oxidation results in a build up of a black oxidative and other deposits commonly called 'sludge' within the central heating systems pipes and radiators. This sludge has a detrimental effect on the circulation of hot water through the system, this problem can culminate in blockages in your heating system. Not only does this prevent radiators from distributing heat effectively but can also determinant damage to radiators, valves and pumps which results in expensive repair bills.
Power flushing your radiators and heating system removes the built up 'sludge' from your system, decreasing fuel bills and prolonging the life of your central heating system. Having your heating system power flushed can help keep you warm during the winter, reduce your fuel bills and avoid a total system failure. But what are the symptoms of a system that has become clogged and requires power flushing? Below are the main symptoms that occur when a system has a high concentration of 'sludge' and would benefit from a power flush.
If your taps output little or no hot water, it is most likely due to blockages in the pipes, resulting from a build up of 'sludge' and the poor functioning of a heat exchanger.
If radiators output black or brown water during bleeding this is a sign that the central heating system has begun to corrode and distribute 'sludge' around your system, power flushing your system can slow this corrosion down.
The build up of 'sludge' & lime scale can cause boilers to operate loudly & even cut out. If this is not rectified the results could include a costly repair or even a replacement boiler, a power flush can help prolong the life of your boiler & make it run quieter.
As your system corrodes over time 'sludge' collects at the bottom of your radiators, a power flush will remove this 'sludge' build up from the system, making it more efficient.
If your radiators are colder at the bottom than the top this is due to the build up of 'sludge' at the bottom of the radiators, if these are not power flushed then the system has to work harder and can end up increasing your fuel bills.
If radiators are cold at the top, this is due to a build up of hydrogen gas, a by-product of internal system rusting. This can be rectified by bleeding the radiators, a power flush will also help to reduce system rusting.
