system flush

Do you find your heating system not heating up as it once did? Or maybe the radiators are cold at the bottom and warm at the top? There could be corrosion occurring within the heating system, which slows the circulation of the water in the heating system. Not only will the heating and hot water take a lot longer to heat up, but in the long run, the system will be consuming more gas and energy to get the water up to the satisfactory level required.

Some common symptoms of corrosion occurring within your central heating system are:

  • Radiators taking a long time to heat up

  • Cold spots on your radiators

  • Frequently needing to bleed radiators

  • Black water coming from the bleed nipple, or from the radiator when you remove it when decorating

  • Vibration or banging noises from the pipework

  • Hot water fluctuating hot and cold when trying to have a lovely shower or bath

  • Noise from your boiler such as banging, clanging and kettling

  • Pump whining and making grinding noises

  • Diverter valve jammed or passing water down the heating circuit in summer when no heating is required

If you are experiencing any 1 or more of these symptoms, our central heating system maybe in need of a 'MagnaCleanse'.

MagnaCleanse is a very effective method to remove corrosion from the central heating system and restore the flow of water inside the system and get the system back to being efficient and save energy costs.

the procedure

You may ask what is the procedure to carrying out a powerflush. Below we have highlighted the process within a few steps, just so you can get an understanding of what to expect.

  1. Drain down the complete heating system

  2. Cut into the most convenient place in the central heating system

  3. Attach the Magnacleanse Filtration System to where the system has been cut into

  4. Ensure all radiator valves are in the open position to allow the flow of water

  5. An effective cleaning chemical such as Adey MC3 is added to the filter which will assist with the breakdown of the corrosion

  6. Fill the heating system back with water and turn the central heating boiler on and put on demand for heating.

  7. The cleaning chemical will now flow through the complete system for 20-30 minutes.

  8. After this, all radiators will be isolated and the MagnaCleanse will concentrate its powerful chemical and flow into 1 rad at a time for 10-15 minutes, and then move on to the next

  9. After all the radiators have been flushed individually, all radiators are opened up and flushed for a final 20-30 minutes

  10. The water in the system is now drained down to a suitable drainage point

  11. On completion a new MagnaClean Filter is installed, Inhibitor is added to the system. The system is filled with fresh water and the system is entirely bled of air and the system is switched on and the system is balanced and all rads are checked to ensure they are all heating equally and efficiently


Central heating filters

Some central heating systems may not need a Magnacleanse flush. But it is still highly recommended to have a filter installed on the system to prevent future breakdowns that will escalate to expensive repairs.

We will carry out a turbidity test, which basically is a test tube which we fill with the system water. If the marker at the bottom of the tube is partially visible we would highly recommend just the installation of a new MagnaClean Professional 2 filter along with MC1 Inhibitor. However if the test proves that the marker is completely not visible, then we will strongly advise a MagnaCleanse with the installation of the MagnaClean Professional 2 filter along with MC1 Inhibitor.

MagnaClean Professional 2 has been expertly designed to maximize the capture of magnetite. Engineered to actively trap virtually all circulating scale, it never stops delivering the very best protection.  Magnetite is the number one contributor to heating breakdowns. Every day corrosion occurs within a heating system. If left untreated, this builds up magnetite causing cold spots on radiators, making heating inefficient and putting unnecessary strain on the boiler.

With products and practices designed to put an end to corrosion and magnetite, these filters and chemicals will reduce energy bills, lower maintenance costs and protect boilers for longer.

Benefits for the Homeowner

  • Reduced heating bills and maintenance costs

  • Immediate ongoing central heating system protection

  • Extends the life of the central heating system

  • Reduced carbon emissions
