Slough Plumber Co
Here is a Vaillant Ecotec 28 pro combi boiler. The customer was complaining of banging noises coming from the boiler and that the hot water and heating was not working.
The heating system and combi boiler was found to be contaminated with rust and Sludge. The radiators are made from iron and with water being in the system this will cause the inside of the radiators to rust and oxide. The protective chemical called central heating inhibator has probably been either diluted or completely drain out of the system over time and not replaced.
To get rid of the boiler noise and to get the system working. A full system powerflush is needed.
In this video we use a Kamco Quantum CF90 powerflush machine complete with a Kamco magnetic filter kit and boiler pump connection kit.
We hook our powerflush machine to the vaillant boiler by removing the pump head and attaching our machine to the heart of the boiler and system to get rid off and clean the contaminated parts.
