Inhibitor and Magnetic Filters: Protect Your Boiler
Inhibitor and a magnetic filter prevent the sludge and corrosion behind many boiler faults.
Two inexpensive measures dramatically extend boiler life by preventing internal corrosion.
Inhibitor
A chemical inhibitor added to the system water prevents the rust and sludge that cause cold radiators, kettling and component wear.
Magnetic filter
A magnetic filter on the return pipe captures circulating metal debris, keeping it out of the boiler and protecting the heat exchanger.
Key takeaways
- Inhibitor prevents corrosion
- A magnetic filter captures debris
- Both extend boiler life
- Fit during install or servicing
