Over the past 10 years working as a heating engineer, I have experienced first-hand the issues we face in the UK caused by poor water quality and corrosion in domestic heating systems.

Due to this, flushing heating systems is a task I perform on a regular basis. However, in doing so, I am never quite satisfied with the results. I have struggled to find a method that produces the water quality I expect with the efficiency I require.

For the first few years, I power flushed every installation I was completing but found this to be either overkill for new systems, or too time consuming and customers were not willing to pay for this method. Whilst results were good, this wasn’t an ideal method for day to day flushing.

I then started using a magnet method. However, on completion of a system flush, the water quality was not as I expected. This was possibly due to the fact that the water was only circulating in only one direction, and also that only magnetic contamination was being removed.

From there, I moved to using mains water to flush and found this much more effective. Despite this, I still felt better results could be achieved if the water was diverted around the system to create reverse flow. Swapping hoses over was just too awkward and the risk of water spillage was high.

I began to wonder if there was an answer which could resolve these issues and make every day flushing much easier. From there, I designed a device that combined the successful elements of flushing and resolved the issues I often experienced. This new device could instantly change flow direction, causing turbulence within radiators. This allowed all contamination to be disturbed, and therefore removed, whilst running off the mains water supply.

The Thoroughflush has now been used on many systems, old and new. The results are amazing in the short time it takes to complete a system flush.

Whilst preventing corrosion remains a challenge, improving water quality quickly and effectively is now much more achievable. I believe flushing systems out to a high standard and following modern water treatment methods will benefit the homeowner and help our industry greatly.
