WUN/WND "High Efficiency" Series (Single-Stage)

High Fuel Efficiency for homeowners with optional horizontal venting. High efficiency gas furnaces save money by produce more BTU's while using less fuel than 80% efficient furnaces.

The WUN and WND series furnaces are designed to save you money on utility bills. The condensing gas furnace may be installed as a single pipe system, using indoor air for combustion, or as a 2-pipe sealed combustion system, bringing in fresh outdoor air for combustion. Since the flue gases are at a much lower temperature, the furnace may be vented vertically or horizontally with schedule 40 PVC or ABS pipe. Plus, the unit is Air Conditioning ready with an adjustable speed blower motor for maximum comfort.

In addition, these furnaces are factory assembled, wired and tested to assure safe, dependable and economical operation. These furnaces are designed for both residential and commercial installations.

 2-Stage High Efficiency Furnaces are also available.

HOW TO SELECT A 90%+ EFFICIENT GAS FURNACE

Estimating the Furnace Size

You can refer to an estimate or proposal from a local contractor, refer to the size of your existing system that you may want replaced, or use the sizing estimation chart provided on this page.

Use the map to determine your Region based on the location of your home. Using the equipment charts, find your Region and go down the column to locate the range that covers the Square Footage of your home. Follow the row to the right to determine the recommended Furnace for your application.

NOTE: These tables and charts are intended to be used as a guideline only. The information is based on conventional window space (<15%), insulation and building construction. Only use these tables as a reference. When including a finished basement, use 1/2 of the finished basement square footage with the rest of the area being calculated.
