The compact design allows you to use this even in tight spaces, and the propane design allows this to work even without electrical power. This heater is great for small homes or rooms that cannot have larger heaters because of their size, and it can help efficiently heat a small area.
    Customer Questions & Answers
    By Joel from Durango, CO on March 15, 2013
    I currently live at 7000 ft altitude and I want to use this unit. Can this unit be used at my altitude?
    By Dawn H. on March 15, 2013

    Yes, it would be a problem. The manufacturer states that at altitudes above 5,000 feet, shut down of the heater by the ODS system may occur due to reduced oxygen levels above this altitude.

    By Joel from Durango, CO on March 15, 2013
    Why won't this work at a 7000 ft elevation?
    By Collin C. - NFI Master Hearth Professional on March 18, 2013

    The primary issue is in regards to the pilot light. Vented furnaces and propane barbecues will have a more constant supply of oxygen to fuel any pilot light they may have. These types of appliances also do not have oxygen depletion sensors. Because a vent free heater has an ODS and relies on oxygen from within the home, pilot outages can occur. The ODS will come configured for use at sea level, so the lower oxygen levels at your elevation cause it to perform poorly.

    By Tonya from Houston, MO on August 22, 2014
    Are you able to replace a thermocouple on this unit if need be?
    By eFireplaceStore on August 25, 2014

    The manufacturer does not offer a thermocouple by itself. Instead, the entire ODS pilot assembly must be replaced if there is any failure of the thermocouple. Because of the sensitive nature of vent free appliances, this is the case with most of these models.

    By Roxanne Lindsay from San Ramon, CA on December 21, 2016
    I am looking for information on the SunStar Corcho heater. Are there any restrictions for the San Ramon, Contra Costa, California area?
    By James on December 21, 2016

    I provided the link to the manual for
    SunStar Corcho Vent-Free Propane Infrared Heater with Manual Controls -

    By Tina from Jasper, GA on October 27, 2015
    We are replacing a heater that is wall mounted and the gas hookup is to the left when you are facing the heater. Can you tell us which side the gas hookup of this SunStar thermostat control SC18 vent-free radiant infrared propane room heater is located on?
    By Brennan W. on October 28, 2015

    The gas line connects to the right side of this heater.

    By Bruce from Gatineau, P.Q. on January 25, 2014
    I have a cottage up north where temperatures can go down to -30. The enclosed and insulated crawl space below the cottage has electric baseboard heaters to ensure a warm area for the plumbing. Recently, the power went out for a few days and it cost me a pump and a new hot water tank. As the area where the pump and water tanks are located closely together, could one of your thermostat controlled units solve this as a "stand-by" source in case the power goes out? Would the propane tank need to be located outside?
    By Collin C. - NFI Master Hearth Professional on January 27, 2014

    This type of heater can indeed be used as a backup source of heat to keep equipment from being damaged in a power outage. By code and for safety reasons, the LP tank should indeed be located outdoors. LP will vaporize at temperatures as low as -44 degrees Fahrenheit, but the volume of fuel available at temperature up to -10 is fairly minuscule. As such, you may be best to bury the tank in an underground enclosure, as this will ensure the tank is kept at a constant temperature and a ready supply of fuel is only available. The only downside is that accessing the tank in heavy snowfall can be difficult and the initial labor to bury the tank can be more costly.

    By David from TN on March 5, 2013
    Can this be wall mounted?
    By Tommy H. on March 5, 2013

    Yes. It is designed for use on the wall or floor.

    By Garry from Middletown, TRI on December 30, 2016
    Does this heater come with a hose, or elbow to connect to the propane tank?
    By Will M. on December 30, 2016

    This heater will not arrive with any rigid or flexible gas connection as these items should be supplied by a qualified installer (plumber, gas fitter, etc.).

    By Coby from Forest Knolls, CA on September 26, 2012
    Does this need to be hooked up to our propane tank outside, or does it have its own propane tank like a propane barbecue or an outdoor heater? Also, is this convection and radiant?
    By Collin C. - NFI Master Hearth Professional on September 26, 2012

    This unit could either be hooked to the LP supply tank for your home or can be used independently on a smaller independent cylinder. For prolonged operation, I strongly recommend plumbing the heater to your central LP gas line. This will allow the unit to operate for hours at a time, without loss of BTU capacity.

    This heater is strictly radiant; however, a blower can be added to convect heat as well. The blower that is compatible for this unit is located in the Accessories section of the item page.

    By Tony from Millersburg, OH on December 15, 2015
    I have a 20 by 24 foot shop with a 9 foot ceiling. Would this SunStar thermostat control SC18 vent-free radiant infrared propane room heater be large enough or would I need the next size larger?
    By eFireplaceStore on December 16, 2015

    If the shop is well insulated, this would be the perfect size for your application. If the building is poorly insulated or is in a location that is subject to prevailing wind, I would recommend sizing up to the SC30 model.

    By LARRY SLICK from Columbia, SC on August 2, 2012
    I'm looking to purchase an infrared propane heater similar to this one to heat 350 sf of an lightly insulated home in the SC area . I need a heater that will shut off once a certain temp is reached. I read a review that states that this does so on "low" which a review stated is was 60 degrees. Is there a heater similar to this available with a remote thermostat.
    By Collin C. - NFI Master Hearth Professional on August 2, 2012

    We do indeed offer many infrared heaters that have thermostatic controls, such as this model, which will modulate the heaters operation based on the set temperature.

    Unfortunately, these settings are only able to be set on the heater itself. We do not have any models that can be used with a remote thermostat at this time.

    By Ted from Bankston, AL on February 16, 2016
    What are the dimensions of this SunStar heater?
    By Will M. on February 16, 2016

    The dimensions are 19 3/4 in. W x 25 in. H x 9 1/2 in. D.

    By Merry from Tucson, AZ on December 4, 2015
    Can you connect this SunStar thermostat control SC18 vent-free radiant infrared propane room heater to a 10 or 20 gallon propane tank or does it have to be a 100 gallon tank?
    By Will M. on December 4, 2015

    Local code and manufacturer's requirements will require that rigid fittings be used to a propane tank stored on the exterior of the home. In addition, an LP supplier will have to advise on tank location, which will be subject to further code provisions. Unfortunately, this eliminates the rationale of hooking this product up to a smaller tank. You will likely not be pleased with the performance of the appliance after these provisions as the tank capacity and colder weather will affect vaporization rates, causing frequent performance issues. This heater will use .84 pounds of liquid propane an hour and smaller tanks would struggle to keep up after only a few days of normal operation in this scenario, even if this type of installation were allowed.

    By Trey from Ottawa, CAN on April 18, 2016
    Is there an exterior thermostat or is it on this SunStar heater? What would it cost to ship it to Canada?
    By Will M. on April 19, 2016

    We are unable to ship any ventless system to Canada as ventless hearth systems are banned in Canada.

    This offers a modulating thermostatic bulb system that is integral to the valve and not compatible with a remote.

    By Garry from Middletown, RI on December 27, 2016
    What pressure regulator is used for the SC18 heater?
    By Owen on December 27, 2016

    Not 100% sure of what you are asking so I will give you a few possible answers:

    the Regulator Settings on the SC-18 LP is 6.0" W.C
    SC-18 NG is 10.0" W.C.
    the Inlet pressure on the SC-18 LP is 7.0"-14.0" W.C.
    SC-18 NG is 11.0"-14.0" W.C.

    If you are looking for the manufacturer of the regulator I will have to check with SunStar and see if they have that information.

    By Jennie from Santa Fe, NM on April 18, 2016
    Can one use this SunStar heater in a bedroom?
    By Will M. on April 19, 2016

    While this model will not be acceptable to install in a bedroom as it has a Btu input of over 10,000, the SunStar Corcho Vent-Free Propane Infrared Heater with Manual Controls - 9,500 BTU should be acceptable so long as the area is greater than 475 cubic feet
