We always recommend that our customers have a MagnaClean magnetic filter fitted after a power flush. It’s the best way to make the results of your power flush last, and it’s why we extend our guarantee from 3 years to 5 when we fit one.
What a MagnaClean filter does.
When we power flush your central heating, we introduce a mix of water, cleaning chemicals and rust inhibitors. The inhibitors stay in your system after we’ve gone and help slow the corrosion that produces black iron oxide sludge, but they only last for a limited time.
A MagnaClean filter carries on where they leave off. It captures iron oxide and limescale as they pass through your system and traps them, letting only clean water flow back round. That keeps your heating free-flowing, your radiators warm and your boiler working at its best.
Why it’s worth fitting one.
An untreated system slowly fills up with deposits again, and you’ll start to see the same problems: hot and cold spots on radiators, boiler noise and cut-outs, and bills creeping back up. A filter helps you avoid that:
- It drastically reduces any future build-up of sludge.
- Your boiler and radiators last longer.
- It helps you keep the savings of up to 25% a power flush can bring.
- It extends our power flush guarantee from 3 years to 5.
Why have a power flush before your filter is fitted?
A MagnaClean filter can only catch what’s moving. In older systems that are heavily blocked, the deposits are settled inside radiators and pipework, and they need to be loosened and forcefully removed with power flushing equipment. The chemicals left behind after the flush keep any remaining deposits moving, so they reach the filter and get trapped.
Even new builds usually need a newly installed heating system power flushed to validate the boiler warranty, so a power flush followed by a filter is the best start for any system.
Other upgrades that protect your system.
A MagnaClean filter is the most popular upgrade we fit after a power flush, but it isn’t the only one:
- Electrolytic scale inhibitors fit on your cold water inlet and reduce limescale on every appliance that uses mains water, with no maintenance.
- Limescale inhibitors paired with a MagnaClean filter give your system protection from both sludge and scale.
- Thermostatic radiator valves, wireless room thermostats, Honeywell zone valves and unvented cylinders help you use less energy to heat your home.
