| + | Direct vent,these unit are usually 90% efficient or better. Pulls combustion air from outside, and returns exhaust gasses to outside. Burners are enclosed and does not use inside air for combustion. These units are better for use in garages and shop space where chemicals, gas, paint or other flammable products are used and stored. Warms up quickly. | ||

| + | Usually 80% efficiency. These units do not have a sealed combustion chamber and have open flame. They use indoor air to supply the combustion process. You must be careful when painting, or storing flammable products. | ||

| + | *In-floor hydronic heating must be left on nearly all the time because it's slow to heat up. This type of system requires the use of a boiler. It's a great way to heat shops, painting areas or chemical storage spaces because the boiler is usually located elsewhere, i.e. inside the home or an enclosed utilty room. You can heat your house and garage this way because there is no air transfer. | ||

==Venting== | ==Venting== | ||
| − | + | A gas burning appliance must be vented to the outside. Care must be taken to ensure the proper type venting pipe is used. It's also important to maintain minimum distance from combustible materials. Most units require vertical venting with at least 5 feet of vertical piping, though some newer units can be vented horizontally. | |
==Combustion air== | ==Combustion air== | ||
| − | + | ||
| + | When utilizing an open burner design heating unit, an air supply is required for it to burn and vent properly. The air is taken from the outside and should be a constant supply; merely opening the garage door periodically is not sufficient. Usually 4 to 6 inches depending on the BTU's produced. If there is no combustion air, the system will begin to consume the oxygen directly from the breathing air and pull the entire space into negative pressure. The exhaust gasses may then spill out of the combustion chamber. | ||
