ENERGY GUIDE

Electricity vs natural gas

Direct electric resistance heating converts roughly one kWh of electricity into one kWh of heat, while gas heating has combustion losses.

How to compare costs

A heat pump changes the comparison because its delivered heat can exceed the electricity it consumes.

Include electricity time-of-use tariffs, gas standing charges and the heating equipment efficiency.
