A novel hydronic distribution system, ideal for heated floors.


Simplification and Safety

This novel system eliminates the need for traditional hydronic parts such as pressure tanks, bubble removers, pressure regulators, zone valves, and manifolds. It also eliminates all the pipe joints and complications and failures that go with all those components.

Key Features:

  • Simple and Understandable

  • Easy Installation and Maintenance

    • Install with basics tools​

    • Replace any part with basic or no tools

    • Easy to add water for start-up

  • Easily works with up to 3 heat sources; such as electric, gas, solar, wood

    • Great for off-peak electric appliances​

  • Supports 4 Thermostat zones with priority zone setting.

    • Supports up to 9 heating loops​

    • Any heating loop can be assigned to any thermostat by simply moving a jumper

    • Supports both traditional and smart thermostats

  • Safe to work with

    • Low pressure and low voltage​

    • Can be powered from a 12 volt battery if desired for off-grid applications

Why It's So Easy to Set Up and Maintain

  • Installation using basic tools - No "Professional" tools required.

  • High quality silicone hoses for zone pipes and pumps.

  • Fewer valves, pipe joints, and other parts than typical installations.

  • Diagnostic LED lights help you understand what is working and what is not.

  • The system protects itself using low pressure and moderate tank temperatures.

  • Alarm board option provides buzzer and dry contacts for remote alarming.
