Heat Pump                         Oil Furnace

Which makes more BTUs/dollar to heat your home:
a Heat Pump or an Oil Furance?


  - A Heat Pump's heating output BTUs range varies from 1,900 BTUs at -10 F, to 20,900 BTUs at 70 F.
  - A Heat Pump's energy efficiency (COP) range varies from 159% at -10 F, up to 4.84% at 70 F.
  - An Oil furnace typically has a constant efficiency rating of 85%.
  - When the weather gets very cold you most likely would need more than one Heat Pump to heat your home.
  - A Heat Pump is an excellent primary heating source for a home and an oil furnace is a good supplemental heat source.
  - A Heat Pump could reduce your heating season bill significantly.
  - Try modeling your home with 1, 2, or 3 Heat Pumps installed.
  - Calculations on this page can be for installed Heat Pumps.
  - The Heat Pump used for calculations below is a Fujitsu Model Halcyon 12LRS.
