I researched various ways to heat my haven. Electric was too expensive, I wasn't comfortable with a wood-burning stove, and baseboards or a floor heater took up too much floor space. In the end I opted for a ceiling-mounted radiant heater, like the kind you see in arenas. I live in the country, so my heater is powered by propane, but the units can also be hooked up to natural gas. You have to specify which fuel source before you order one.

Unlike conventional heaters that heat a room's air, the energy from a radiant heater warms up objects in the room, including the floor. These objects, in turn, return heat to the room, the same way the sun warms the earth's surface, which then warms the air. This system eliminates the need for fans to move the heat. My heater also takes the air it needs for combustion from outside via a duct, meaning it doesn't use shop air that might contain dust particles---in other words, and a safe system. And other than cleaning dust off the reflector shield when required, it is virtually maintenance-free. Heaters are available in different configurations; for those of you familiar with BTUs, these units can produce from 25,000 to 40,000.

My system was delivered in two boxes. The heater must be installed at least 7'-0 from the floor with a minimum clearance of 4 from the top of the reflector to the ceiling. Using the directions and the hardware provided, I had the system hanging within 30 minutes. I installed the fresh-air intake hose and the thermostat but had a contractor (booked ahead of time to coordinate a hook-up date) prepare the exhaust vent and gas line. Once the Propane Company delivered and hooked up the tank, and inspected the system, I had heat!

The two-tube, 11 1/2'-0 unit I bought cost $900. It runs from November to mid April. My first season cost about $200 in propane; natural gas would be even cheaper. I tried four different locations for the thermostat, settling at six feet from the garage door. It's set at 20 deg. Celsius (72 deg. Fahrenheit) and I leave it at that temperature all the time. Comfy.





Radiant Tube Heating With Easy Radiant Works

Not a sucking, but blowing system
The blowing burner system was conceived by Easy Radiant Works over thirty years ago, and is how the EZ Duzzit achieves a long luminous radiant flame. The most important burner components, such as the fan with self oiling bearings, electronic controls, etc., are not exposed to the heat or moisture of the exhaust flues. This considerably increases the lifetime of the burner and allows Easy Radiant Works to provide their famous "No Ifs, Ands, or Buts" 4 year guarantee.

Long flame high efficiency
The burner, designed and manufactured by Easy Radiant Works, creates a long, luminous flame surrounded with a laminar flow of air for perfect combustion in the infra-red emitting high carbon steel tube. This ensures an even distribution of the radiant heat. This also makes Easy Radiant Works tube heaters extremely energy efficient.

As Quiet as a Whisper
The position of the fan, the supreme motor bearings and the optimized flow properties of the burner make the system almost noiseless.

Comfortable Control
Easy Radiant Works heating systems can be controlled by thermostats. The unit accepts 24v and 120v thermostat control, and is also compatible with facility control systems.

The Combustion
The gas-air-mixture is created in a specially designed burner housing. This mixture is forced through a venturi designed byEasy Radiant Works and the gas and air mixture is ignited by a hot surface igniter. With this construction, natural gas or propane gas is combusted within a laminated air tunnel. The tube is heated by the long flame and combustion gases and emits radiant heat. An integrated aluminized turbulator ensures even temperature distribution over the length of the tube.

Air Intake and Exhaust
The flue gas of the radiant tube is disposed of through an exhaust system to the outside. The combustion air can be taken either the inside of the building, or ducted in from the outside through an air intake system.

Radiant Tube Heater Construction
We use only the highest quality North American made components and materials in our products. The combustion tubes consist of aluminized or galvalume steel that withstand high temperatures and are corrosion resistant, providing additional durability. The tubes go through a high temperature surface coating treatment by which the radiant heat is increased. The radiation-optimized, highly polished reflector directs the radiant heat to the area where it is needed. The use of these high quality components results in increased performance, higher levels of comfort, and allows for greater fuel savings that have reached 50% or better.
