System Filter

You have to fit a filter, so fit the best and add two years to the warranty

It’s always been best practice to clean and flush systems for maximum performance when installing a new boiler, but the latest code of practice, BS 7593:2019, is designed to protect the whole central heating system. This means that all boiler installations should have an in-line system filter fitted as standard.

Our System Filter, produced in collaboration with Fernox, will not only optimise the energy efficiency and longevity of the system, it will also add two more years to the boiler’s warranty*. To be eligible, the filter must be fitted on the same date as the boiler and in line with the Manufacturer’s Instructions; both warranties must be registered with Intergas at the same time.

*Contracts excluded.

The System Filter includes a 22mm spigot isolation valve and Fernox’s unique Hydronic Particle Separation with magnetic filtration, which removes magnetic and non-magnetic system debris. When it comes to cleaning, there’s no need to dismantle the filter and, thanks to its encapsulated body, the whole process is fast and easy; there’s no top seal either, so no leaks. The spigot valve works in conjunction with the boiler return valve to isolate the filter or, using just the spigot valve and boiler flow valve, you can easily drain the boiler down via the filter’s flushing/drainingvalve. The system filter is easy to install on horizontal or vertical pipework and comes with a 15-year warranty. And, as it’s made entirely from metal, it’s also 100% recyclable.
