Example Projects

Example job completed in Esher, London (March 2024):

The engineer was called to a large house with 19 radiators. The issue was that only the middle floor (out of three floors) was heating a little. The rest of the radiators didn’t really get hot at all. The engineer changed and upgraded the pump to light commercial and changed the pump valves, which did not really change anything at all for this blocked open vented system.

As this engineer has referred us before and knows what we can accomplish. He recommended us to his clients as the solution, over recommending a new boiler, power flushing or new radiators and valves.

When we arrived, we heated the system to know how bad it is. Out of 19 radiators, only 3 heated correctly. It took us 8 hours to fully clean and unblock the system/pipes and radiators, with 19 out of 19 radiators heating 100% when we were done. We found during the work that the system was partially piped with plastic pipes, that tend to block up easier and harder than copper pipes. We were able to unblock them as well!

Engineers specification on this system: Open vented system with 19 Rads over three floors, 35kw Worchester bosh heat only boiler, main runs are in 28mm copper with all rads on 15mm copper and plastic, 2 x 2 port valves with pressurised bypass and light commercial pump, boiler was cycling as there was not enough flow to run at full power.

If these scenarios sound familiar and you need a good alternative to changing the whole system- contact us using the form below. We also offer a No Fix No Fee deals, so your clients don't risk any more money.

Example job completed in St. Albans (May 2023):

The heating engineer changed the boiler on a sealed system as he thought it would fix the radiators only partially heating up. After the boiler swap did not resolve the problem he tried to power flush the system three times and spent several days trying to fault find.

He eventually gave up and asked his client to book Powder Flush. We unblocked and cleaned the system in 8 hours. The radiators were fully heating up once we were done.

Example job completed in Essex (February 2022):

The client's mother has dementia and she lives on her own. In November 2021 her heating broke down and they called their regular gas engineer. He changed the pump, while they had to take a day of work, to be there with him. Days later, client called him back because the heating still did not work.

He figured that the pump came from a bad batch and went back to change pump for a different brand. Still does not work! He went back and changed the boiler. One day job, straight swap, and power flushed the system on the same day. Tried to commission the boiler, F code Error. Boiler did not stay on for more than 60 seconds. He power flushed the system again, still boiler did not work. He called manufacturer and they send someone, days later.

They said he might have pumped the sludge/rust into the new heat exchanger and recommended changing it. He ordered a new heat exchanger, went back and fit it in. F code error, same problem, boiler did not work. Engineer gives up and askes client to book us.

On the day: We started working on the system at 10am and by 4pm the system was working correctly, with the boiler running at maximum with heating and hot water working like it should. What was it? Hardened rust build up is pipes, that normal power flushing couldn't move.
