MagFlow Filter Guide: Installation, Power Flush, Boiler Service & Heating System Efficiency (2026)
Protecting your heating system is one of the best investments you can make in your home. Whether you want to improve boiler performance, reduce heating bills, prevent sludge buildup, or extend the life of your system, this guide covers everything you need to know about magnetic filters — especially the MagFlow Filter, Powered by DIKA, an Irish brand designed for superior system protection.
1. WHAT IS A MAGFLOW FILTER AND WHY DO YOU NEED ONE?
A magnetic filter captures sludge, rust, and metal particles circulating in your heating system. These contaminants cause:
- Cold radiators
- Blocked pipes
- Noisy pumps
- High fuel consumption
- Boiler breakdowns
MagFlow Filter – Powered by DIKA was created as a durable, affordable and high-performance solution for Irish homes.
Key benefits:
- Protects boilers and pumps
- Improves radiator heat output
- Reduces fuel usage
- Extends system lifespan
- Prevents sludge returning after a power flush
- Works on Oil, Gas and Heat Pump Systems
2. MAGFLOW FILTER PRICING 2026
Prices depend on installation, pipe sizes, and system condition.
Type of Work Average Cost (€ EUR)
MagFlow Filter only (supply) €90
MagFlow Filter + Installation €250
Power Flush + MagFlow Filter from €500
Boiler Service + MagFlow Installation from €120
What affects the price?
Amount of sludge in the system
Pipework layout (S-Plan, Y-Plan, gravity)
Radiator quantity
Boiler condition
Accessibility around pipework
Tip: The fastest improvement in a home is Power Flush + MagFlow installation — radiators heat up 30–40% better.
3. SINGS YOUR HEATING SYSTEM HAS SLUDGE
If you notice any of these, you need MagFlow Filter:
- Radiators cold at the bottom
- Black water when bleeding radiators
- Boiler constantly running but still cold rooms
- Pump noise or boiler cycling
- High fuel consumption
- Frequent air-locks
- Sludge destroys efficiency — MagFlow stops it immediately.
4. POWER FLUSH + MAGFLOW FILTER: THE PERFECT COMBO
A power flush removes years of sludge and restores full circulation.
Why combine the two?
- Power flush cleans the system
- MagFlow prevents sludge returning
- Radiators heat evenly
- Boiler works with lower strain
- Lower fuel bills
DIKA Home Maintenance uses a professional flushing machine and chemicals to restore the system to near-new condition.
5. THERMAL CAMERA RADIATOR AND UNDERFLOOR SURVEY
Using a thermal camera allows us to detect:
- Problem What It Means
- Cold bottom Heavy sludge
- Cold top Air trapped
- Patchy radiator Blocked channels
- Slow heat-up Pump or flow issue
Thermal images show exactly why the system needs cleaning or protection.
6. MAGFLOW FILTER INSTALLATION GUIDE
MagFlow Filter can be installed on:
- Back boiler units
- Oil boiler
- Gas boilers
- New Heat Pump systems
- S-Plan systems
- Y-Plan systems
- Combi boilers
- New Builds and Retrofits
Installation takes 30–60 minutes depending on pipework.
Steps include:
- To be installed only on Return
- Shut off valves & drain section
- Fit MagFlow in recommended flow direction
- Add inhibitor
- Check leaks
- Test magnetic core for sludge
- Bleed air from the system
- Start boiler & check circulation
7. BOILER SERVICE + MAGFLOW – Why It Matters
A clean boiler is safer, more efficient and lasts longer.
During a service we check:
- Burner condition
- Combustion efficiency
- Heat exchanger
- Pump performance
- Filters and seals
- Condensate System
Installing a MagFlow during a boiler service is ideal — the system becomes protected and clean at the same time.
8. MAINTENANCE TIPS FOR BEST PERFORMANCE
- Clean MagFlow at 6 mounts
- Add inhibitor every 2 years
- Service the boiler annually
- Perform thermal camera checks for cold spots
- Power flush older systems every 4–5 years
- A protected system runs hotter, faster and cheaper.
9. SHOULD YOU HIRE A PROFESSIONAL?
Heating systems are complex. A qualified installer will:
- Diagnose sludge correctly
- Install the filter safely
- Check for leaks
- Balance the system
- Perform power flush if needed
- Test Radiators and Boiler performance
Choosing a professional ensures proper protection and long-term results.
