ProCom 10,000 BTU ventless natural gas garage heater, Digi Mart USA News: People who use their garage as a workshop, home office, gym, or other space may want a stand-alone way to keep it warm in winter, since extending central heating to a garage is generally not recommended. The publisher highlights the ProCom 10,000 BTU Ventless Blue Flame Heater as one option for homes with a natural gas supply, listing it at Home Depot for $129.10 as of the article’s writing.
The unit uses what ProCom calls Blue Flame Technology, which requires no vent, so it is easier to install than a vented model and none of its heat is lost outside. It offers five heat settings, can be floor-standing or wall-mounted, and includes thermostatic control and push-button piezo ignition.
The publisher notes that garage installations must meet specific clearance requirements, such as wall mounting at least 18 inches above the ground.
Installation requirements vary. The article cites earlier ProCom manuals stating that installation and service must be performed by a qualified installer, service agency or the gas supplier, and says whether a homeowner can install it personally depends on local building codes and whether a permit or inspection is required.
The gas supply connection uses a ⅜-inch fitting.
The publisher also flags safety concerns. California is among several areas that have banned ventless heaters, and the open flame poses a fire hazard if flammable vapors such as gasoline, kerosene or paint thinners are stored in the garage.
Ventless gas heaters produce carbon monoxide, which is odorless, invisible and poisonous, and can cause nausea, dizziness, headaches and vomiting without ventilation. The article notes the heater has an oxygen depletion sensor that shuts off gas for safety, but because it does not detect carbon monoxide, the publisher suggests adding a separate carbon monoxide detector.
Heating capacity is another consideration. According to the article, 10,000 BTU is enough for a single-car garage with suitable insulation but not for a two-car garage.
Ventless gas heaters can also increase condensation, which could lead to damp walls and rust on equipment and tools. The publisher concludes that the heater may be an economical option, depending on what is stored and how the garage is used, and notes that hot air units or ductless heat pumps may cost more but could be safer.
