Some apliances are made easy to convert for Ng-propane with kits, some
are not and will need alot more work and cost. Check everything out if
you want that future option in your apliances. Hiring someone for a
future conversion could be expensive. I looked at an American Standard
furnace that offered a simple conversion kit , burner jets and gas valve
components and other brands that made no mention of it as I was looking
at dual emergency fuel. Propane is usualy more costly to use but this
depends on your area. In some areas of the US electricity is cheapest,
but only a few. For most Ng is best you need to run numbers on Btu
costs of all fuels of your area.
