Expert Power Flushing Engineers in Edinburgh
Long-term use can clog your central heating system with dirt and sludge. This can explain why your radiators are not as hot as they should be or why some radiators do not get warm at all. Do you have any radiators that do this? A power flush might be the remedy.
This is primarily due to a lack of water quality testing in central heating systems. The dirt, sludge and magnetic particles that stick to the inner surfaces of pipework, radiators and even boiler components.
Dirt and sludge buildup can lead to part failures, poor performance of radiators and underfloor heating systems, and even total blockages of pipework sections.
Power flushing cleans and removes this contamination, keeping your central heating system working efficiently and helping to guard against boiler breakdowns and costly repairs.
We can also provide a system filter, which, once installed, will protect your system for years to come. A water quality test should be carried out during your boiler service, and the filter should be cleaned.
If your system has been in operation for a while, you don’t already have a system filter, or you notice that some of your radiators are cold or have cold spots, it could be time to have your system flushed. Get in touch today to find out how we can help!
Signs That Your Central Heating System May Need a Powerflush
If your central heating system isn’t functioning properly, here are some key indicators that a power flush may be necessary:
- Cold spots on radiators, particularly at the bottom
 - Unusually loud noises coming from the boiler or the heating system pump
 - Discoloured water when bleeding radiators
 - Heating takes a long time to warm up
 - Some radiators are slower to heat up compared to others
 - Radiators remain cold while the pipes are hot
 - The boiler frequently shuts down and needs resetting
 - No water escapes when bleeding a radiator
 - Noisy radiators or boiler
 - Small leaks in radiators
 
If you notice any of these issues, it may be time to consider a power flush for your system.
Power Flushing Questions
Yes, power flushing radiators is often worth it if your heating system is showing signs of inefficiency, such as cold spots, slow heating, or noisy radiators. It helps improve performance, extends the lifespan of your boiler, and can reduce energy bills by clearing out sludge and debris.
Absolutely not. We use protective dust sheets and tidy up after ourselves.
There will be noise from our equipment, but customers should be able to continue like normal, and many still work from home while we do the power flushing.

Immediate response and extremely helpful dealing with the stress of a boiler issue. Resolved our issue and gave advice for worsening should we need assistance in the bear future.Posted on Lindsay SmithSeptember 29, 2025Trustindex verifies that the original source of the review is Google. Great and efficient service - Ryan installed smart thermostats throughout the house, fitted new valves to 2 radiators (and replaced an old manual thermostat which didn't look great for no extra charge which he did without me even asking). I wouldn't hesitate to recommend.Posted on lynn moirSeptember 22, 2025Trustindex verifies that the original source of the review is Google. Had problem with my smart heating system - Ryan arrived same day within just an hour and got me back up and running. Would use again for other gas heating issues in the future.Posted on Graham SmithAugust 26, 2025Trustindex verifies that the original source of the review is Google. Very good service. Cane exactly when he said he would and fixed my boiler.Posted on AlbertLai2020August 19, 2025Trustindex verifies that the original source of the review is Google. Ryan is so fast to check my boiler next day. He is the first engineer I met so far to fully explain what the problem of the boiler is. Therefore I can estimate what is the ceiling price for repairing the boiler. After he has fitted the PCB to the boiler on the second visit, the boiler works again and no further repair is required. My tenant is very happy. I will definitely call Ryan again for any boiler issues in future. Thank you so much for Ryan!Posted on Ajit NaranJuly 25, 2025Trustindex verifies that the original source of the review is Google. Efficient both with the job and time highly recommendPosted on Mark HannaJuly 14, 2025Trustindex verifies that the original source of the review is Google. We purchased our new home and asked Ryan to come and service our boiler. Communication was fast and easy with details confirmed via email and reminder text messages too. Works were done quickly and professionally. Ryan talked me through what he was doing and left the areas as found. We then asked him back for additional pluming work which was also done to a high standard. Invoice came via email and payment was easily done too. Great to support a local firm and to find someone who provides a top level of service; rare these days!Posted on Charlie HibbertJune 7, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed our new hot tap & service our house heating and hot water system annually, with an accompanying logical explanation of how the our system actually works, something other engineers weren’t able to do. Would highly recommend.Posted on Sarah PandeyJune 3, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed a new boiler with Tado thermostat and removed our old hot water tank, as well as replacing a bathroom tap. The team were extremely professional, polite and kind and did a great job. We were very pleased with the work. We had originally got 3 quotes from different companies and Thermatek were the most reasonable of the 3. We would definitely recommend them. Thank you!
