Best 5 Vented Garage Heaters (Horizontal & Vertical) Reviews
Natural gas heaters are an excellent option to heat your garage or workshop when it gets cold and can heat big spaces. They operate on the natural gas line of your house or building. You can purchase ventless garage heaters, but most people opt from safer vented garage heaters. They require venting systems that depend on the heater.
I will present to you the list of the five best vented garage heaters, giving you enough options to research and finally choose the perfect heater for you.
Guide For Buying A Vented Garage Heater
What Is A Vented Heater?
A vented heater is a heater that requires some kind of external ventilation system. The reason for this is that these heaters use natural gas, and if built up inside enclosed spaces can be dangerous (e.g. carbon monoxide poisoning). Normally heaters are vented through a chimney or wall.
Vented Or Ventless?
A vented heater is generally safe as no toxic gases are retained in your garage or shop and provide you with clean heat. However, some people opt for ventless heaters. These heaters do not use any form of ventilation, but generally, have reliable safety features such as the oxygen depletion sensor which monitors oxygen and CO levels, and are usually easier to install.
Roof / Vertical Ventilation
If you decide to vent the heater through your roof, this means you run the ductwork from the heater’s flange through a hole in the roof. Make a circle roughly the same diameter of your ductwork, drill the hole and pull it through. The length of the ductwork protruding from your roof depends on your area’s regulations. Just make sure everything is fastened and tight.
Wall/ Horizontal Ventilation
You can vent your heater through a wall by drilling a hole in it and running to it a 4 inch galvanized sheet metal duct from the heater. Use metal screws to tighten everything. A B vent pipe is usually used because of its insulation that prevents excessive heat. Make sure the venting system is appropriate to the size of your heater.
Venting Kits
In order to set up your desired ventilation system, you will probably need to purchase the necessary venting components. Garage heater vent kits usually consist of piping and elbows (vertical or horizontal), shields and termination kits.
