PRODUCT OVERVIEW

Permanent Gas Radiant Heating for Outdoor Spaces

The Space-Ray Cold Blocker is a high-efficiency, high-performance gas-fired radiant heater specifically designed for outdoor heating in commercial environments. Unlike portable patio heaters that need replacing or refilling, the Cold Blocker is engineered for permanent installation, providing a long-term, stable, and consistent heat source for your outdoor space.

Its robust construction is fully weatherproof, offering protection against wind, rain, and snow. This durability ensures reliable performance in all types of weather, making it a dependable choice for year-round outdoor heating at bars, restaurants, cafes, golf driving ranges, and other commercial outdoor entertainment spaces.
