Electric heat can be affordable if a heat pump is used instead of an electric heater. A heat pump efficiency is 300% compared to a regular electric heat.
An electric heaters is 100% efficient. It converts into heat all the electric power it gets. Even at 100% efficiency electric heat is still very expensive because of high costs of electricity.
A heat pump does not convert electricity to heat. Instead, heat pumps use electricity to move heat between indoors and outdoors. This is how they achieve 300% efficiency.
Heat pumps is not something new. A heat pump is a modified air conditioner. At summer time it is pumping heat OUT of the house. At winter time a heat pump reverses its operations and is pumping heat INTO the house.
Using a heat pump instead of an air conditioner allows to use the investment all year around instead of a few short weeks in the summer and reduces the heating bill at that.
