How does the outdoor furnace work?

How The Furnace Works

  • The firebox is surrounded by water.
  • That hot water is pumped (by a small pump located either on your furnace or in your house) through a pipe loop to the heat exchanger in front of your blower fan.
  • The blower fan blows the radiated heat from the hot water into your duct system, into your home for clean, non-dry, even, comfortable heat.
  • The “heat-reduced” water returns to your furnace, is re-mixed with the “hot” water, and continues the circle, providing you with consistent, clean, efficient heat that won’t dry out you, or your home!
  • You can utilize your existing blower, duct work, and house thermostat!
