Power Flushing in Warrington & Surrounding Areas
Boost Your Heating Performance & Cut Energy Costs
If your radiators are slow to heat up, making noise, or leaving cold spots, it’s likely your heating system is full of sludge and debris.
Our professional power flushing service restores your system’s performance, protects your boiler, and helps reduce your energy bills — keeping your home warm and efficient.
What Is Power Flushing?
Power flushing is a deep clean for your central heating system. Over time, rust, sludge, and scale build up inside radiators and pipes, causing poor circulation and reducing efficiency.
We use a specialist high-powered flushing machine and professional cleaning chemicals to safely remove the build-up — helping your system run like new again.
Installing a new boiler?
Most boiler manufacturers now require a power flush as part of the installation. It clears out existing sludge that could damage your new boiler and helps keep your warranty valid.

✅ Boiler Protection – Reduces strain on key components.
