When installing a new boiler we at BeeXpress always include and install a magnetic filter at the same time.
It makes sense. The filter prevents magnetic and non magnetic debris from going into the boiler where it could corrode parts, block up pipes and scale up the heat exchanger. Although a Powerflush is done at the same time as the installation there will always be some debris left in the heating system and oxidisation will always occur over time inside the radiators. This causes rust to appear which just adds to the dirty sludge that is inside every heating system.
There are a number of magnetic filters on the market.
The best known is the Adey designed Magnaclean Professional 2. It’s the original filter and is very easy to fit. However in compact spaces or jobs with odd pipework it’s not the best on offer.
In these cases, we always use the Fernox Omega Filter. It has a fully brass body and can be installed any way needed so is ideal in every situation.
A magnetic filter can also be installed on old heating systems.
It makes even more sense to have a filter installed on an older boiler than on a new boiler. An old system will have a lot of sludge and debris in the radiators and pipework as well as inside the boiler. While it may still provide you with plenty of hot water and heating it will be costing you more every year to run. That’s because whenever debris is caught up inside the boiler it will need to work harder to heat up the same amount of water that it used to. By having a magnetic filter installed (and ideally doing a powerflush at the same time) you will be protecting the boiler from new debris which will reduce the cost of the gas bill every year.
When installing a filter on an older system we would need to drain the heating system as the filter is installed close to the boiler which is often on the ground floor. This type of job would most likely take around 2 hours to do and would be priced accordingly.
