Everyone is always asking us which fuel is better. Unfortunately, it is not an easy answer. The simplest fuel is electric heat. Heat up the wire and you have heat. The problem is the cost of operation.
The next is an air source Heat Pump. It does not need any fossil fuels, it does not need a chimney, is easy to install, and under the right installations, it can be efficient. The problem is it needs backup heat which is usually electric making this system very expensive to operate.
Oil furnaces and boilers are making strides into efficiency and comfort. With boilers up to 90% and furnaces up to 87% if oil is your only option, you have some choices.
Propane gas is another option if natural gas is not available. The equipment is up to 98% efficient, it offers a wide range of features and benefits and because of the technology, they are the most comfortable heating system available.
The best system is natural gas. It is the least expensive heat source, the equipment is up to 98% efficient, it offers a wide range of features and benefits and because of the technology, they are the most comfortable heating system.
A nice comprises for oil or propane users are a duel fuel system. It is a combination of fossil fuel for the extremely cold days and a heat pump for the moderately cold days.
The chart below shows the cost of the different fuels and the cost after the efficiency are applied.
