Counterflow Furnaces

Efficiently-designed comfort heating

for up to three rooms!

Electric Home Heater

The practical choice for those areas where natural or propane gas is not convenient to install. It provides low-cost, floor-to- ceiling comfort (31,400 Btu/hr), is thermostatically controlled, and is ideal for basements and room additions.

Direct-Vent Counterflow

Forced-air circulation comfort heating system uses only outside air for combustion, as the burners are completely sealed within the combustion chamber. Combustion is discharged outdoors through the wall; this eliminates the expense of a chimney…all vent caps include a built-in “Bird Guard”. All vent material is included. IDEAL for garages.

40,000 – 62,500 Btu/hr

35,000 - 65,000 Btu/hr

Top-Vent Counterflow

This model’s powerful counterflow blower system receives air at ceiling level, warms it and quietly delivers it at floor level to give an equalized floor-to- ceiling temperature! Installs easily and inexpensively.
