Forget the hazards of portable heaters with long, wild cords. In an industrial environment, a safer, more permanent, professional solution is key.
Industrial unit heaters are a great solution for heating vast commercial spaces, such as large warehouses, factories, or showrooms. They provide increased safety over their portable alternatives and don't take up any of your valuable floor space.
In order to select the right industrial unit heater for your application, you will need to consider a few factors, the first of which is how it will generate heat for your space. Depending on the fuel or heat source you choose, you may then need to select from some venting, heat exchanger, or orientation options.
Choosing Your Industrial Unit Heater's Fuel or Heat Source
Consider your accessibility to various fuels, fuel and electricity prices in your area, and any pre-existing heating systems. Based on these factors, your preferred industrial unit heater will generate heat through one of the four mediums or fuels listed below:
One of the most popular ways of generating heat is combusting (i.e. burning) gas. If you have a gas line easily accessible, natural gas (abbreviated "NG") usually the least expensive way to heat your space. If your industrial site already has appliances or machinery that use natural gas, it's likely that an installer could extend that gas line to the site in which you hope to place your industrial unit heater.
For those without easy access to natural gas, liquid propane (abbreviated "LP") is a readily available and still relatively inexpensive option. Initially a part of natural gas, propane is typically sold in its liquid state by the gallon and needs to be stored on-site in large quantities. The negative side of using propane is the need to consistently monitor the amount of fuel you have left. If you run out, so will your heat!
A Helpful Tip: Converting NG to LP
Because using liquid propane is less common than using natural gas, industrial LP unit heaters are often not stocked, causing longer lead times and higher prices than their equivalent NG version. Luckily, most NG unit heaters have compatible NG to LP conversion kits (sold separately), which are typically in stock. If you need your industrial liquid propane unit heater quickly, we advise purchasing the same unit in a natural gas configuration and adding a conversion kit from the product page's accessories tab.
If other fuel options are not available, or your facility is in a location where electricity is particularly inexpensive, an industrial electric unit heater might be the best choice for you. Rather than plugging into an outlet like a basic portable unit heater, industrial electric unit heaters are direct wired, helping you maintain a safe workplace by keeping your walls and floor space clear of wires.
Industrial electric unit heaters are generally sized smaller than other industrial unit heaters, so it will often be best to arrange multiple heaters in your space for complete coverage.
If you have a hot water boiler already heating up your factory or warehouse, you can take advantage of the hot water it already produces with a hot water unit heater. While gas-fired unit heaters are always designed with your safety in mind, some people prefer not to add another combustion site to their building if they don't need to.
Industrial hot water unit heaters just contain a heat exchanger and a blower. The heat exchanger uses hot water from your existing hydronic system, and the blower simply pushes air across or through the heat exchanger to be heated and then out to your workspace.
