System Requirements

• Locally acquired domestic gas-fired hot water heater (40,000 BTUH input)
• 115V single-phase service
• The system has been designed for up to 5 – 4′ x 25′ mats. If your application is 500 sq. ft. or less but configured differently, we will be happy to customize it for a $250 fee

How it Works

The RZH™ module is attached to your water heater. Hot water is pumped through BioTherm’s Roll’N Grow® Mat. Plants are placed directly on the mat. The media temperature sensor tells the head unit when to cycle on & off to maintain optimum media temperature.

Why Root Zone Heating?

Rootzone heating is a proven system for starting your plants and growing on. Plants respond to media temperature control with faster, more robust growth.
