Power Flushing
(Increasing The Efficiency of your central heating System)

Power flushing your central heating system is a way of making sure your central heating system is running at optimum efficiency and thus saving you money on your heating bills.

Power flushing is designed for the efficient removal of lime scale and sludge from heating systems, radiators and boilers. It does this by circulating water and flushing chemicals at a high velocity around the central heating system, via a power flushing machine. This machine then purges the dirty water from the system with a high flow of fresh clean water and makes your heating system more energy efficient (Thus saving you money on your energy bills).

Power flushing will restore central heating systems with circulation and boiler noise problems caused by corrosion deposits and sludge. By having your central heating system power flushed it will remove these deposits and the problems that they cause. Most central heating systems contain Sludge even if the problems aren’t being shown. So by Power flushing your central heating system this will restore the systems efficiency. Problems that will occur if your system is in need of a Power flush is Noisy Boilers, Cold spots at your radiators, noisy operation, reduced efficiency and, in some extreme circumstances, failure of the boiler.

The high efficiency of modern condensing boilers which are developed to minimise fuel costs and pollution means that they are more prone to problems caused by corrosion debris and sludge in the central heating system water.

Power Flushing

Symptoms to suggest your system needs a Power flush

  • Dirty black or brown water present when bleeding radiators. This means that your system has corrosion (Which makes it less energy efficient).
  • Cold Spots in your radiators. This is due to black sludge in your radiators called iron oxide. (This means your central heating system is working harder than it needs too).
  • Radiators cold all over or not working due to blocked pipes.
  • Poor Circulation in the heating circuit, radiators taking a long time to warm up.
  • Noisy Boiler from sludge and lime scale build up (This increases gas consumption and thus your bills while not heating your home).
  • Boiler cutting in and out, and no or poor circulation due to blocked / weak pump.

Benefits Of Power Flushed Your Heating System

  • More Efficient central heating and hot water (This means cheaper Gas and Electricity bills every month).
  • Optimum working hot radiators and hot water.
  • Corrosion protected central heating system.
  • Reduced fuel bills (Due to Higher Energy Efficiency).
  • Peace of mind (As less can go wrong).
  • Central heating system cleaned as thoroughly as possible.

While you’re getting your Central heating system Powerflushed why not upgrade your Radiator Valves to Thermostatic Radiator Valves (TRV’S)?
