The Power of the Power Flush: Cleaning and treating central heating systems

Powerflushing is the generic term for cleaning a central heating system with the aid of chemicals and a powerful self-contained flushing unit. With the aid of a flow reversing valve a high degree of system cleanliness can be achieved.

Corrosion: Silent, deadly, costly... corrosion begins the moment water enters a heating system. When the water is hot, corrosion attacks with greater speed. Corrosion is generally caused by the presence of oxygen, but can also be brought about by galvanic effects, which occur when different metals are connected. Aluminium is especially prone and for this reason should never be connected directly to copper or brass. When corrosion occurs, black magnetite is formed which can restrict circulation in radiators, cause premature pump failure, and form deposits in heat exchangers which manifest themselves in boiler noise and lost efficiency. Gassing, another side effect of corrosion, requires radiators to be bled in order to restore circulation. Pinhole corrosion can give rise to alarmingly rapid perforation and loss of radiators. It is normally due to overuse of flux and lack of effective flushing in new systems.

Scale: The problem of scale varies considerably across the country depending on the water supply. In hard water areas such as the East and South East of England, scaling is especially severe due to the high lime content in the water. Lime gives rise to rapid `furring` of the heat exchanger where it causes two major problems - noise and increased fuel usage.

In modern boilers the effect of scale on boiler efficiency and fuel usage is dramatic. An eggshell thickness of scale can increase fuel consumption by as much as 10%. Scale often gives rise to boiler noise commonly known as `kettling`. This can be an extreme nuisance to the householder who has to put up with banging noises that can be heard all over the house.

Microbiological growth: Frequently open to the air from their position in the loft, feed and expansion cisterns are prone to contamination from all sorts of micro organisms such as bacteria and fungi. Once in the cistern, they can breed and give rise to unpleasant growths and slimes, which can foul the heating system and cause blockages and deposits.

Symptoms:

·         Boiler noise

·         Radiator failure

·         Inefficient boiler

·         Radiator cold spots

·         Kettling

·         Failed pumps

·         Leaking radiators and weeping joints

The Powerflush system is extremely effective in clearing and restoring central heating systems, which always lose their efficiency over time. To maximize your system’s cost effectiveness, it is recommended you schedule a power flushing service at a minimum of once every three years. Atlantic Plumbing & Heating’s high pressure Power-flush solution, including chemical cleansing and neutralizing fluid, will rectify any problems listed above if your system is otherwise fully functional.

We also recommend using a Power-flush when adding a new boiler to your heating system. This will maximize the benefit of adding a new boiler, support the boiler warranty and prolong the life of your new boiler as well as your heating system.

Once the system is cleaned out, a central heating inhibitor is introduced to prevent these symptoms reoccurring.
