Should we install an electric or propane boiler for our project at
Whistler, BC, Canada?  Whistler has a piped propane system and it will
be installed accessed on site, and electricity is also on site.  So
the question is which is cheaper?  Propane furnaces basically come as
two types normal efficiency and high efficiency.  Electric is simply a
set efficiency.
