Southern Burner Heaters

Southern Burner  unit heaters are exactly what the name implies... individual units designed to be used singly or in groups to heat a unit of space to meet individual greenhouse requirements. Southern Burner heaters circulate warm air over the greenhouse somewhat like the heat rays from sunshine, from the floor up. They do not radiate heat because radiated heat goes directly to the top of the glass in the greenhouse and is lost. With Southern Burner Unit Heaters, the temperature at the top of the greenhouse can be held within 5 to 7 degrees of the floor temperature.

Southern Burner heaters have been in use in greenhouses all over the United States since 1932. In thousands of applications, this method of inexpensive heating has helped make if possible for the average person to have and enjoy a 'backyard' greenhouse, and at the same time make it possible for the large greenhouse operators to expand their glass area to the maximum without the expense of costly heating systems. Southern Burner heaters will heat the same area as other systems on as little as half the fuel cost.

Convenient... Economical... Space-saving... and most important, plants an flowers grown in greenhouses equipped with Southern Burner heaters have always been top quality.
 

A-1 Vented Orchid Greenhouse Unit Heater

The A-1 Vented Orchid Greenhouse Unit Heater The Model A-1 Unit Heater is an enclosed flame heater that requires venting to the outside of the greenhouse. It also requires a fresh or combustible air intake from the outside of the greenhouse.

The A-1 is square in design - 16.25 inches wide, 17.5 inches deep and 25 inches tall, constructed of non-rusting mill polished aluminum outer shell, supporting a 24 gauge aluminized steel firebox with vertical flues for maximum air circulation with a stainless steel burner enclosed rated at 25,000 B.T.U. This heater must be vented with a 3 inch vent pipe for proper draft.

In areas where there is heavy snowfall, it is necessary to arrange to keep the ends of the air intake pipe open. This can be accomplished by tilting something over the outside opening while the snow is falling.

Intake pipe can be offset to one side. It does not have to be in center of heater. The pipe extending outside must be no more than 12" vertically from inside floor grade, and should stop about three inches from the heater, and about four inches up from the floor.
