primoSchwank Radiant Heater Technology

primoSchwank high intensity heaters are synonymous with one of the highest radiant efficiencies in the world.

The Delta Mixing Chamber

Inside the patented Delta Mixing Chamber, the gas-air mixture is preheated to 570°F [300°C] to create a more efficient combustion.

The Combined Radiant Effect

Radiant energy is created from heating the ceramic tile to 1740°F [950°C], the inside of the reflector to 930°F [500°C]. This heater therefore produces both high and low intensity infrared radiant heat – this unique technology is called “combined radiant effect”.


All our heaters are certified by CSA International for safety compliance.

When combustion stops or the gas pressure is too low, the gas valve automatically closes. This prevents gas from escaping into the room.

Every heater is individually tested before it leaves our factory.


Schwank heating systems can be controlled by single thermostats – our unique TruTemp Thermostat – or even by a central building management system.
