In 1952, Sunderman Manufacturing introduced the SunDair® commercial heater line. We have three different models available, ranging in BTU from 157,000 to 320,000, and many different configurations. SunDair® heaters are a great quality heat source for your greenhouse or shop. Available in Oil, LP and Natural Gas.

Please call us for help in deciding which heater would be best for your particular heating situation.
