Water heating is the third largest use of energy in most homes today. Propane-fueled water heaters are ideal for manufactured homes because they offer many advantages over electric models, including:

The better recovery rates of propane gas water heaters are a big asset in the construction of manufactured homes. A propane gas water heater can heat more than twice as much water in an hour as a comparable electric model. In manufactured homes, maximum use must be made of space, and the fact that a much smaller propane water heater can do the job of a larger electric unit is an important consideration.

Venting Options for Propane-Fueled Water Heaters

A wide variety of venting options are available to meet the requirements of today's manufactured home designs. Three common possibilities are:

• Atmospheric Venting: This is the most common method used. Water heaters vented in this way do not require a blower to expel flue gases, thereby saving installation and operating costs. Instead, atmospheric pressure (the weight of the air) pushes exhaust through vents and out of the house.
• Power Venting: Combustion products are vented outside the home with the assistance of a blower. Units can be vented vertically or horizontally.
• Direct Venting: This system is designed for installations where vertical chimneys are not available or would be too costly to install. Outside air is brought in for combustion and venting is done directly through the wall. Most units require zero clearance at sides or rear, which allows for maximum space utilization.
