How does a gas fired unit heater work?

How does a gas fired unit heater work?

Natural gas or propane is ignited in the burner. The flames heat up a metal heat exchanger and exhaust out of the flue. The heat exchanger transfers its heat to the incoming air. The furnace’s blower forces the heated air into the ductwork and distributes it throughout the home.

What is a gas fired unit heater?

Gas-Fired Unit Heaters Gas unit heaters require the use of either natural or propane fuel for combustion and require the heaters to be vented outside to get rid of flue contaminates. These heaters can be mounted relatively quickly and provide a lot of heat in a small box.

How do you size a gas unit heater?

To calculate the size unit heater required for your space, use the following formula: Calculate the cubic footage of the space to be heated by multiplying building length x width x ceiling height. A 30 x 40 pole barn with 14 foot average ceilings* will have (30x40x14=) 16,800 cubic feet of space to heat.

Are home gas heaters safe?

Do Natural gas heaters produce carbon monoxide?

When properly maintained and adjusted, gas heaters produce low amounts of carbon monoxide. One cause of carbon monoxide poisoning from unvented heaters– incomplete combustion caused by lack of air–has been virtually eliminated in newer heaters by use of Oxygen Depletion Sensors (ODS).

How do I know if my heater is leaking carbon monoxide?

How to tell if your furnace is leaking carbon monoxide
