The top five reasons why Electric heater is better:
Cheaper to buy - In general, electric heater are cheaper to buy than other heating options.
Easier To Install - Unlike gas heating, there is no need for complicate duct work and venting. You can simply plug them into an outlet. However, some more permanent version needs to be wired a line voltage. Although you could do-it-yourself, we recommend that you contact a certified electrician for the job.
Low Maintenance - They are quite simple. Either they work or not. They are not that many moving parts to troubleshoot. Since they are no ducts or venting involve, you don’t need to have an annual maintenance program to ensure proper CO venting is in place. As a whole, it is safer to work with electricity than natural gas which is a combustible gas.
100% Efficient - As a heater, 100% of the energy from the electricity it used is converted into heat. 100% of that heat is then blown into the room directly to warm up the cold air. The main disadvantage with central gas heater, a lot of the heat is lost in the ductwork between your furnace and the room it is heating.
Last longer - With proper maintenance, they will last you 20 to 30 years. While gas heater has a life span between 10 and 20 years.
