John Wood Plumbing

We can maintain or install any natural gas boiler, including the Worcester Bosch, Ideal and Vaillant range. We have been trained by all three manufacturers to carry out work on their boilers. Not only that, we are Vaillant accredited and are able to offer an additional warranty upgrades over and above the standard manufacturers warranty.

Over time, sludge and dirt can build up in your central heating system reducing circulating efficiency and causing a degradation in performance. Cold spots on your radiator could be an indication that your central heating system needs a clean.

We offer specialist Power Flush services and can help to restore the efficiency of your central heating system. A Power Flush works by connecting a powerful cleaning unit and magnet filter to your central heating system in such a way that water flows from the radiators to the magnet filter to collect iron oxide sludge.

A phosphoric acid based rust removal chemical is added to the system and the boiler is switched on. Radiator surface temperatures are then measured using infrared thermometers to detect cold/ rust spots.

By concentrating flow through individual radiators and vibrating the radiators with a special device, rust particles are dislodged and pass through the pipework to the magnet filter where they are trapped and prevented from re-entering the heating system.
