Protect your heating system.
Reduce unplanned maintenance. 🔧
Poor system water = corrosion, sludge & higher energy bills.
Correct water treatment helps commercial heating systems:
✅ Run more efficiently
✅ Last longer
✅ Avoid costly downtime

Cold outside? ❄️
Cold spots on radiators mean wasted heat inside.
Sentinel X400 and X800 system cleaners remove sludge from heating systems, helping radiators transfer heat efficiently and keep homes and buildings warmer.

Limescale isn’t just a nuisance - it’s a budget killer. In commercial heating systems, just 1.6mm of scale can increase fuel usage by up to 12%, leading to efficiency losses and expensive downtime.
Don't let scale compromise your system's efficiency.
