Description

Riverstone Industries RSI Greenhouse Work Shop Radiant Heating Propane Gas System – 18,000 BTU Ventless Radiant Heater

The Riverstone Industries RSI Greenhouse Work Shop Radiant Heating Propane Gas System is a high-quality ventless heater engineered to provide steady, direct warmth for greenhouse and workshop environments. Designed to operate off propane (LP) gas and built-in radiant technology, this heater efficiently distributes heat across your space while keeping fuel use optimized. With a built-in blower fan and thermostat control, you can maintain comfortable temperatures easily, whether you’re nurturing plants through cold spells or heating your work space.

Included in the system are removable legs for floor placement and a wall-mount bracket for flexible installation options. The silent battery-operated ignition system simplifies start-up, while the oxygen depletion sensor (ODS) enhances safety by automatically shutting the unit down if fresh air levels drop too low. Engineered not only for performance but also for peace of mind, this gas heater is suited for greenhouses, garages, workshops, sheds, and more.

Built in the USA and backed by a limited warranty, the RSI Radiant Heating Propane Gas System is crafted to deliver years of reliable heat. The multiple radiant burner tiles generate up to 18,000 BTUs of heat, capable of warming spaces up to approximately 600 sq ft (up to 1,000 sq ft in well-insulated structures). This efficient design saves on energy costs over time compared with less advanced heating solutions.

Whether you’re protecting delicate plants from frost or adding warmth to your workspace, this propane radiant heating unit delivers consistent performance you can count on. With thoughtful safety features and flexible mounting options, it’s a smart solution for seasonal or year-round heat control.
