Heaters Help not used for Tent Heaters

If you do not know how much BTU you need to heat your space a simple formula can be followed:

1. Figure cubic square feet of space to be heated

Length x width x height
Example: 50' long x 30' wide x 15' high= 22,500 cubic square foot of space

2. What is the average temperature outside?

This could be approx
Example: outside temp is 15 degrees

3. What do you want the temperature to be in the building?

Example: 55 degrees

4. .The heat rise is (55 degrees inside - 15 degrees outside) = 40 degrees.

5. Multiply the cubic square foot by the heat rise.

22,500 x 40 degrees =900,000

6. Multiply by .133

133 x 900,000 = 119,000 or approx 120,000 BTU./HR needed to heat the building

Why Portable Heat?

Portable heaters provide clean, efficient heat for all types of garage, warehouse and outdoor applications where a permanent heat source is unavailable or has been temporarily interrupted.

How Does Kerosene Forced-Air Heat Work?

Kerosene heaters are used in outdoor applications (brick and block laying, building construction) to keep workers comfortable and to prevent newly-applied concrete from freezing. Since their fuel source is self-contained, they're truly portable wheels and handles are included. Kerosene heaters aren't affected by fluctuations in temperature. They provide instant, safe, portable heating at temperatures as low as minus 20 F. The fuel system. An air pump forces compressed air through a hose and a burner nozzle, creating a vacuum and causing fuel to rise from the tank. The air and fuel mix to create a fine mist that's sprayed into the combustion chamber. The ignition/control system. The ignitor mechanism provides a spark that ignites the air-fuel mist inside the combustion chamber. The safety control system automatically shuts down the unit in the event of loss of flame or lack of fuel. The air system. An electric motor turns a fan that pushes air into and around the combustion chamber,heating it and propelling it out the barrel and into the surrounding environment.

How Does Propane Forced-Air Heat Work?

Propane forced-air units are clean-burning and odor-free, ideal for indoor projects such as drywalling, painting, finish work, flooring, concrete curing, cabinetry, and many other do-it-yourself projects. They can either be easily refilled or conveniently connected to a central fuel source. The fuel system. The hose and regulator assembly attaches to the propane (LPG) supply and provides fuel to the heater at the proper pressure. The ignition/control system. The ignitor mechanism provides a spark that ignites the air-fuel mist inside the combustion chamber. The safety control system automatically shuts down the unit in the event of loss of flame or lack of fuel. The air system. An electric motor turns a fan that pushes air into and around the combustion chamber, heating it and propelling it out the barrel and into the surrounding environment.

How Does Propane Convection Heat Work?

Convection heat creates an "envelope of warmth" that's ideal for workshops, work sites, patios and recreational activities. They need no electricity to operate, yet deliver high-output heat at a surprisingly low cost. The fuel system. The hose and regulator assembly attaches to the propane (LPG) supply and provides fuel to the heater at the proper pressure. The ignition/control system. The Piezo ignitor mechanism provides a spark that ignites the fuel supply. An automatic control valve shuts down the unit in the event of loss of flame or lack of fuel.

How Does Propane Infrared Heat Work?

Reddy Heater infrared units "warm like the sun," heating people and objects before heating the air. They're also wind-resistant, making them an ideal source of heat for drafty and open areas where the heat can't be contained. The hose and regulator assembly attaches to the propane (LPG) supply and provides fuel to the heater at the proper pressure. Every ReddyHeater infrared unit features an automatic control valve shuts down the unit in the event of loss of flame or lack of fuel.
