How Much Does a Power Flush Cost?
Power flushing is priced by system size and is often paired with a magnetic filter.
A power flush clears sludge to restore heat and protect your boiler. Here's the cost picture.
What you get
A full system flush removes magnetite sludge, restores even radiator heat, and improves boiler efficiency; we add inhibitor afterward.
Pricing factors
Cost scales with the number of radiators and system size; pairing with a magnetic filter prevents re-fouling.
Key takeaways
- Priced by system size
- Often bundled with a magnetic filter
- Restores heat and efficiency
- Add inhibitor to protect the system
