Power Flushing

Is your central heating showing signs of any or all of the following?

  1. Cold spots on the radiators
  2. Radiators cold at the top
  3. Radiators cold at the bottom
  4. Blocked pipes and valves due to sludge and/or limescale
  5. Banging noises from the boiler
  6. Noisy pipes due to restricted flow
  7. Boiler cutting out due to a blocked or damaged pump


Home Gas Supplies' highly efficient Power flushing equipment can circulate your entire central heating system in your home with chemical descaler and cleaner which within a few hours will clean your sytem. we will them refill your clean system adding inhibitor to maintain your systems efficiency going forward. The pressurised water is pumped through all the trickiest parts of your radiators, central heating pipework and valves which will result in a smooth and anti-clogged heating system. The prices include the cost of the descaler, cleaner and inhibitor chemicals. They are fixed prices, there are no hidden costs.


System Power flushing from £350.00 *

We can also supply and install a magnetic filter on your central heating system before we complete the work at a discounted rate.

A magnetic filter will take care of your system throughout the year working with the inhibitor to prevent sludge and magnetic material build up. The magnetic filter should be serviced at the same time as your boiler each year to ensure optimal performance of your central heating.


Supply and install Magnetic filter in the same visit as a Power flush £180.00 


*Price is dependant on size of the central heating system and therefor the volume of chemicals required for the clean and flush. Please note the term 'radiator' includes any panel raiators, heated towelrails or kick space heaters which are running on the central heating system.

Price includes VAT at the current rate of 20%.


NEW UPDATES: BS 7593:2019- Let Home Gas Supplies help you save money and comply with the new British Standard which replaces BS 7593:2006 which has been withdrawn with immediate effect.

Installers will need to be aware of the following standards when it comes to the new British Standard:

  • An in-line filter needs to be fitted to every system

  • Carry out a chemical clean and fresh water flush before fitting the inhibitor

  • Cleaning methodologies can be improved with external magnetite capture equipment and mechanical vibration of radiators

  • Annual water test to test level of inhibitor and system cleanliness

  • Every 5 years, the inhibitor should be re-dosed or a full system water test carried out

  • Includes closed loop heating and cooling circuits

  • Biocide is essential in cooling and low temperature heating systems

  • Consider biocide for higher temperature system.

Speaking about the new British Standard, ADEY Chief Technical Officer, Dr Neil Watson said: “We welcome the publication of the fully revised BS 7593:2019. The changes made acknowledge that chemical water treatment isn’t a fit and forget solution, and magnetic filters shouldn’t just be considered a ‘nice to have’. Including these solutions in British Standard’s BS 7593 recognises a critical shift in moving the industry towards a holistic approach to system maintenance.

“A high proportion of boilers that fail in the first year do so because of poor water quality, so by introducing regular testing and redosing, proper system cleaning and the mandatory installation of an in-line filter to the industry’s code of practice, we can significantly improve the efficiency and life expectancy of every household system. This represents massive potential to contribute to the reduction of carbon emissions.”
