Limescale Prevention
Combimate prevents calcium deposit formation in hard water areas by releasing food-grade Combiphos into the water supply. This phosphate-based solution coats internal surfaces, stopping scale build-up on boilers, taps, and pipework while maintaining mineral benefits. Ideal for properties across 60% of the UK's hard water regions.
Corrosion Protection
Our technology forms protective barriers against soft water corrosion in metal pipework. Combiphos inhibits oxidation reactions that cause pinhole leaks, particularly effective in Scotland's naturally soft water systems. This dual-action protection maintains both hard and softened water installations without altering water chemistry.
Boiler Protection
Combimate safeguards boiler heat exchangers from scale accumulation that reduces efficiency by up to 12% per millimetre of build-up. By maintaining thermal transfer efficiency, our system lowers energy bills and extends boiler lifespan. The Lifetime Guarantee covers up to 500 towards repairs if scaling occurs under proper maintenance.
Pipe Protection
Our inline devices protect entire domestic water networks, preventing scale in hidden pipework and visible fixtures. Combiphos treatment maintains consistent water pressure and flow rates by inhibiting deposits in both plastic and metal piping systems across various property types.
Combiphos Refills
Annual refills with 800g Combiphos spheres ensure continuous protection. The simple 5-minute replacement process requires no special tools, using provided 'O' ring seals for secure fitting. Regular maintenance sustains optimal phosphate concentration (2-3ppm) for complete system protection.
Questions
How does Combimate prevent limescale?
Combimate releases Combiphos phosphate crystals that coat internal surfaces, preventing calcium deposits while maintaining water's mineral benefits.
Is Combimate suitable for soft water areas?
Yes, it provides corrosion protection in soft water systems by forming protective layers against aggressive water's metal-leaching effects.
What warranty does Combimate offer?
3-year manufacturer's warranty (registerable) and a Lifetime Scale Prevention Guarantee covering up to £500 in boiler repairs.
Where can I install Combimate?
Suitable for 15mm or 22mm pipework in any UK property with hard/soft water, protecting whole systems or individual appliances.
How often does Combiphos need refilling?
