Is this more efficient than comparable models built in the mid-1990's?
By Kevin E. - Fireplace Specialist on February 6, 2013
Sunstar has only updated the body of this heater since the 90's. The operation and efficiency have not been changed. As the manufacturer put it, "she's the same old gal with a new skirt."

Is an automatic blower available for this unit?
By Collin C. - NFI Master Hearth Professional on September 16, 2013
Unfortunately, a blower is not available for this particular class of heater. Only when stepping up to the 18,000 BTU version of the heater is a blower available.

I am looking for a heater that I could use in a small greenhouse (approx. 10' x 12'). What does "manual controls" mean? Can i set the temperature or is it just on/off?
By Collin C. - NFI Master Hearth Professional on March 20, 2013
The particular unit does indeed have simple on/off controls, with no thermostat option. Unfortunately, there is not a propane version of this heater with thermostatic controls. However, we do offer another manufacturer that does offer an infrared heater with this option. The unit is the Empire SR10T Infrared Vent-Free Gas Heater with Hydraulic Thermostat Controls - Propane. The unit has a slightly greater capacity and has proven to be a more reliable brand.

I am trying to compare the efficiency of a ventless propane SunStar Corcho heater with an electric space heater. How many BTU's are produced per gallon of propane?
By Collin C. - NFI Master Hearth Professional on October 1, 2012
Each propane supplier is different, but the average supplier's propane will contain 91,500 BTUs per gallon. Based on that average, this heater would operate for roughly 9 1/2 hours on one gallon of propane.

What altitude is this unit certified for?
By Will M. on December 2, 2014
The ODS pilot assembly for vent free heaters is calibrated to operate normally up to elevations of 4,500 feet. Above this elevation, the oxygen depletion system will cause the unit to shut down.
