Why Schwank gives you more heat for your money
Did you know that every radiant heater produces both infra-red and convection heat? It's true. In fact, as much as 65%* of the heat produced by a radiant heater can be convection heat that rises to the ceiling and is largely wasted.
What about Schwank infrared radiant heaters? Even our economy performance heaters deliver more infrared radiant heat than competing models. And our top of the line combined intensity supraSchwank is the world leader with 81% infra-red output!
To satisfy heating and comfort requirements of a building with a one million Btu per hour heat loss, the illustration below compares the required input and the sensible heat output that is delivered to the occupancy level for various heating system technologies.
- In North America, the standard for certification of a luminous type radiant heater is 35% IR efficiency.
- Currently, there is no IR efficiency standard for low intensity tube type heaters - only a combustion efficiency requirement of 70% minimum.
Independent certified lab results confirm that Schwank luminous heaters have the following infrared radiant efficiencies:
