How can I tell which type of furnace I have?

Your furnace is Electric if:

• You do not receive a natural gas bill from a utility company or,
• You have a propane tank

Your furnace is Gas if:

• You see a black iron pipe running to the furnace or,
• You see a flame during heating

You have a Boiler if:

• You have radiators, baseboard heaters or radiant tubing throughout your home
• You do not have vents connected to ductwork in your house
