Product information

Description

General description

Calmag H&V HV800PF Fast Acting Power Flush cleaner is a rapid cleaner designed for older central heating systems, effectively removing corrosion deposits and scale in just 1 hour to restore system efficiency. This powerful cleaner eliminates magnetite and limescale deposits from heat exchangers, radiators, underfloor heating, and pipework, ensuring a more uniform distribution of heat and reducing energy bills.

Technical specifications

  • Volume: 1 litre
  • Coverage: Sufficient for cleaning a typical system of up to 10 radiators
  • Recommended for larger systems: 2 litres
  • Recommended for badly fouled systems: 2 litres for a typical system
  • Non-toxic and 100% biodegradable
  • Non-hazardous and zero COSHH rated
  • Usage

    Calmag H&V HV800PF is ideal for power flushing and works effectively in cold systems. Its unique formulation combines three different chemical technologies to penetrate and dissolve corrosion and limescale deposits rapidly. It acts as a dispersing agent under neutral pH conditions, eliminating concerns associated with traditional acidic cleaners. This product will not clear a completely blocked pipe.

    Only just used it, drained the system, put in the cleaner, now wait and see what comes out when I drain and refill again in couple of weeks.
