Power Flushing in Hertfordshire by 3Flo

3Flo offers Hertfordshire’s affordable power flushing service to keep your central heating system functioning properly. We clean oxide sludge, dirt and lime scale from your central heating system to reduce flow blockages, which are known to result in the deterioration of parts of your boiler.

What is Power Flushing?

Power flushing or central heating cleaning is a high flow but low pressure deep clean for your complete central heating system and boiler. Using 3Flo’s advanced power flushing equipment our expert power flush team removes the sludge build up and lime scale in your central heating system that can prevent it from working properly.

We connect our power flushing machine to your central heating system and pump a special flushing formula around the pipes and radiators. This process forces out the collection of debris and lime scale and results in a faster, evenly distributed heating system and stable hot water temperatures.
