Power Flushing & System Cleaning

At C4 Heating, we specialise in professional power flushing and central heating system cleaning. Over time, all heating systems build up sludge, rust, and debris (known as magnetite), which causes cold spots on radiators, boiler noise, and blockages. Using specialized equipment, we rapidly flush out this harmful build-up, restoring the flow and efficiency of your entire system. Whether you have a noisy boiler or cold radiators, our service removes contaminants to keep your home warm and reduce your running costs.

  • Yes, when performed correctly by professionals. We use controlled pressure and safe, chemical cleaning agents that are designed to clean the internal surfaces of the system without damaging pipework or radiators.
