Have any studies been done to confirm the efficiency of Schwank infrared heaters?
Yes, engineering studies supported by ASHRAE have determined that using standard infrared heaters the total BTU input of a heating system can be reduced by up to 15% compared to calculated design heat losses. Tests performed by a certified independent laboratory confirm primoSchwank and supraSchwank radiant efficiencies in the 65 to 82% range. This means the total BTU input with Schwank heaters can be reduced from 27% to 41%, depending on the Schwank infrared heater employed.
