Efficient 22kW U-Tube Gas Radiant Heater for Industrial and Warehouse Heating
The Powrmatic SRP PU20 is a gas-fired U-tube radiant heater designed to provide efficient infrared heating for warehouses, workshops and industrial environments. With a heat input of 22 kW, this model delivers effective radiant warmth across working areas where conventional warm-air heating systems may struggle due to high roof spaces or frequent door openings.
Using advanced infrared radiant heating technology, the PU20 warms people, machinery and floor surfaces directly rather than heating the surrounding air volume. This significantly improves heating efficiency and reduces heat stratification, making it particularly suitable for industrial buildings and warehouse spaces.
The U-tube emitter configuration provides strong radiant heat coverage while maintaining a compact installed footprint compared with longer linear radiant heaters. Combined with a high-efficiency aluminium reflector and gas burner system, the heater directs infrared energy precisely into the occupied zone, improving comfort and reducing wasted heat in roof spaces.
Supplied with the MC200 optimised digital controller, the PU20 allows accurate temperature control and improved energy management for professional heating installations.
