With the massive popularity of natural gas as a fuel source for home heating systems, it’s not surprising that so many people view it as the only option. Though natural gas is a great choice for many reasons, it is thankfully not the only option available. Whether due to limitations on the availability of natural gas, or simply the desire to use a non-combustion system, more and more people are making use of electric heaters in their home. Let’s examine one of the more common electric heaters, the electric boiler, and how it can benefit your home.
How it Works
An electric boiler is actually fairly similar to one powered by natural gas. The only real difference is that an electric boiler eschews any sort of combustion to create heat, instead using several heating elements to warm the water being circulated around the house.
In a gas boiler, the heat exchanger is suspended over the flames of the burner assembly. Water flows through the heat exchanger and is heated by the fire below before flowing into the house. An electric boiler is a little different, with the heating elements actually inside the heat exchanger with the water supply. The heating elements themselves are basically very thick metal wires, coiled and connected to the electricity supply. As the system runs an electrical current through these wires, it meets resistance that causes the coils to heat up. The now-hot heating elements heat the water in the heat exchanger before distribution.
Why Install an Electric Boiler?
There are many reasons to prefer an electric boiler over other heating systems, the first of which being efficiency. Electricity is often more expensive as a fuel type, compared to natural gas. However, natural gas heaters vent a lot of heat out of the house as combustion gases, which are useless to the heating system and dangerous to the homeowner. As an electric boiler does not combust fuel, almost all of its heat goes directly into the water used to heat the house. Electric boilers also require a lot less maintenance, due to their lack of moving parts compared to combustion heaters.
