Sentinel X400 High Performance Cleaner restores central heating system efficiency in older setups. It clears magnetite sludge and cold spots fast. For instance, it ensures even heat distribution. Plus, it lowers energy bills. This Sentinel X400 cleaner for old boilers revives systems cost-effectively. It meets BS 7593 and Part L standards.

Why Clean Older Systems?

Sludge, limescale, and debris build up over time. They cause cold spots and poor boiler performance. This raises energy costs and shortens system life. BS 7593 and Part L require cleaning before new parts. The Sentinel X400 High Performance Cleaner restores flow and efficiency.

Key Features

• Restores Flow: Clears sludge for better circulation.
• Eliminates Cold Spots: Ensures even heating.
• Preps New Parts: Primes for boilers or radiators.
• Non-Acidic: Safe for all indirect systems.
• BS 7593 Compliant: Meets UK cleaning standards.

How Sentinel X400 Works

The Sentinel X400 High Performance Cleaner targets sludge and debris. It restores radiator flow and heating efficiency. Moreover, its non-acidic formula prevents leaks. Thus, it’s ideal for old systems or new component prep. Pair with Sentinel X100.
