Magnetic Filter Benefits for Your Boiler
A magnetic filter captures sludge before it reaches and damages your boiler.
A small magnetic filter on the return pipe is one of the best protections for your boiler.
What it does
It captures circulating magnetite (iron oxide) debris before it reaches the boiler, protecting the heat exchanger and pump.
Maintenance
The filter is emptied during annual servicing; in dirty systems it dramatically reduces wear and breakdowns.
Key takeaways
- Captures sludge before the boiler
- Protects heat exchanger and pump
- Emptied at annual service
- Best paired with inhibitor
