What is an electric combi boiler?
Electric combi boilers and many other forms of central heating devices are heaters that deliver heat to a building in exactly the same way a conventional boiler would.
Electric heaters and boilers (or electric and gas) provide heat by using electricity (an electrical current that flows into a generator, which then converts that electric current into a mechanical movement) to create steam, which then passes from a heat exchanger to a boiler to transform that steam into water. This creates the heat that is put into a building by a heat pump or forced through a heat exchanger by a heat exchanger.
Electric combi boilers generate steam from the burner to drive one or more air/water heat exchangers, which are essentially heat-pipes that heat water. A heat exchanger is then cooled and returned to a boiler where it then generates steam again and drives the next heat exchanger. At its simplest, the air/water heat exchangers take heat from the outdoor air that is then used to heat the cold water, which is then returned to the building.
The combi boiler has the advantage that it produces hot water at relatively low energy costs, as opposed to forced-air heat pumps (FAPs), which are quite expensive and require expensive gas or oil, to run. Combi boilers do not use diesel fuel to operate, which reduces their high operating costs. There are two basic types:
A high-efficiency (or high-rate) combi boiler has air/water heat exchangers that operate at over 1,000 °F (538 °C) to heat the water (in contrast to the 1,200 °F (640 °C) temperature the heat exchanger in a conventional boiler requires to generate the same amount of heat).
Advantages of electric boilers
The electric boiler uses hot water from outside heating system to heat the home to a steady temperature, even when the outside temperature varies. Electric boilers are used to heat the water before the water enters into the water heater and to heat water after the water leaves the water heater.
This helps in saving money.
The electric boilers come in different types like the hot-water system, the hot-pump system, the electric fire system, electric system and more. These boilers use either electric resistance heat or solar heat to heat water. The electric fire, the hot-pump, the hot-water system and the electric system use solar heat, steam, infrared radiation or electric heat to heat water. There is no need to use boiler for hot water because electric boilers uses electricity to heat the water. The electric burners are commonly used in homes in colder areas.
There are three types of electric water heating systems called the hot-water system, the electric fire system and the electric electric system.
The hot-water system uses electric heat from outside heating system to heat the water to hot water temperature. The water leaves the hot-water system through a closed water inlet and fills into an electric heating tank. The water in the tank is heated to 120°-140° F. When the tank is full the water is circulated through the water heater.
The hot-pump system uses electric pressure to heat water in the tank where the water pressure is regulated so that there is no need to open the inlet pipe to fill into the tank. The hot-pump system used to heat water to hot-pump tank using electric heat is similar to hot-water system.
