Power Flushing

We flush your central heating system with a specialist chemical solution to remove sludge and restore efficiency, leaving your radiators heating up the way they should.

Restore Your Heating System

Power flushing is a process where we pump a chemical cleaning solution through your central heating system at high velocity to break down and flush out sludge, rust, and debris that builds up over time. This kind of build-up is one of the main reasons radiators don't heat evenly, systems become noisy, and energy bills creep up. The process covers the full system: radiators, pipework, and the boiler circuit.

On the day, our engineer connects specialist equipment to your heating system and runs the flush in a controlled process, working through each radiator in turn. We treat the system with inhibitor at the end to slow future build-up. Most power flushes are completed in a single visit, and you should notice an improvement in how quickly your radiators heat up and how evenly the heat distributes.

Better Heat, Lower Bills

We carry out power flushing as part of our broader heating services, and it's something we often recommend alongside a new boiler installation or as a standalone fix for an underperforming system. Liffey Heating is fully insured and our team has over 22 years of experience in heating systems across Dublin. Power flushing starts from €350 and the price is confirmed before any work begins.

If your radiators are cold in patches, slow to heat up, or your boiler is making more noise than usual, a power flush is often the answer. It can extend the life of your boiler, reduce your energy costs, and make your home noticeably warmer. Get in touch and we'll talk you through whether a power flush is the right call for your system.
