Shop heating by system type

Gas or heat pump?

Gas furnace

Strong, steady heat. Usually cheapest to run in cold climates where gas is available.

Heat pump

Heats and cools with one outdoor unit. Usually cheapest to run in warm and mixed climates.

Dual fuel

A heat pump paired with a gas furnace that takes over when it gets too cold.

Sizing and efficiency

  • Size: use our furnace sizing calculator to estimate the BTU you need, then have your contractor confirm with a load calculation.
  • 80% AFUE: uses a standard metal flue and costs less up front.
  • 92% to 98% AFUE: condensing furnaces vent through PVC, need a condensate drain and cost less to run.
  • Propane: many furnaces list a propane conversion kit option for homes without natural gas.
