Heating & Plumbing Systems

For Clear Pipes, Longer System Lifespan, and Cozy Warmth

Extreme conditions in the heating circuit place a heavy strain on the heating water. The consequences are malfunctions and damage. Sludge and crusts accumulate in heating pipes, hindering flow and eventually clogging pipes and valves. The system’s controllability worsens, heating performance and efficiency decrease, and energy consumption rises.
Rust formation is one of the primary issues in the heating circuit. The often oxygen-rich heating water is corrosive to heating pipes, boilers, and fittings. This leads to pitting, leaks, and scale formation. The heating water becomes brown or black and foul-smelling. Limescale deposits also reduce heat transfer efficiency. Even just one millimeter of limescale on the heat exchanger increases energy consumption by about 6%. Over time, a biofilm and sludge layer forms inside the pipes, particularly in underfloor heating systems, clogging the lines.

However, the GRANDER effect is more noticeable in heating water than almost anywhere else.
The circulation revitalization devices protect your heating system with clean, revitalized water!

The benefits of GRANDER in heating and plumbing systems:

  • Reduces rust formation and stabilizes corrosivity
  • Decreases the tendency for deposits
  • Heating pipes, radiators, underfloor, and wall heating systems become clear and free-flowing again
  • Energy savings
  • Increased operational safety
  • Optimized system parameters
  • Improved efficiency
  • Enhanced system protection against technical issues
  • Optimized ongoing operational and maintenance costs
  • GRANDER® devices work without electricity and chemicals
  • Clean and odor-neutral heating water
  • Reduced sludge formation due to significant suppression of biofilm development
  • Lower risk of contamination
  • Reduced outgassing due to decreased gas formation
  • Provides a pleasant indoor climate

Customer experience

Holiday House Brucker, Bavaria

Sylvia and Hannes Brucker are running „Holiday House Brucker“ at Kochel am See, in Bavaria. About 8 years ago they had issues with dirty water pipes in their guest house. A plumber came and suggested installing a GRANDER® unit.
