Oil Furnaces

Today’s oil-fired furnaces are efficient, clean-burning and more cost-effective than many common heating alternatives. Oil heat can deliver more BTUs per gallon, providing much more heat with much less fuel, than other options.

Our oil furnaces

Although we service all models, at North Island Heating we only install the highest quality Granby and Intertherm residential oil furnaces that deliver long-lasting performance and reliable comfort through even the coldest of winters. We’re also northern Vancouver Island’s only certified installer of Roth double-walled oil tanks.
