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.
