Electrode boilers can work on both single-phase and three-phase supplies. If DC voltage is used, electrolysis of water occurs, decomposing water into its elements H 2 at the cathode (negative electrode) and O 2 at the anode (positive electrode). The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. [1]
[citation needed] Electricity is expensive, and with expected rises in the price of electricity, the use of it in electric boilers will come with a large price. [3] Although there is an argument that in the event of a power outage or brownout the boiler would become unusable (in comparison to gas boilers), in fact both systems need an external ...

An electric boiler can be placed in operation quickly, as there is no furnace to reach high temperatures. [4] Environmental impact is displaced to the source of the grid electricity; however, if fossil fuel is being consumed to make electricity, overall efficiency will be lower than direct use of the fuel.
According to the US EPA, geothermal heat pumps can reduce energy consumption up to 44% compared with air source heat pumps and up to 72% compared with electric resistance heating. [4] The high purchase price of a heat pump vs resistance heaters may be offset when air conditioning is also needed.
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
The contaminated area is depicted by the green shape while the electrodes are depicted by the numbered circles. Fig 1. Typical three-phase ERH arrangement. Six-phase heating consists of six electrodes in a hexagonal pattern with a neutral electrode in the center of the array. The six-phase arrays are outlined in blue in Figure 2 below.
These boilers can be rated up to 500,000 lb/hr. [2] The wall membrane of the boiler are dual welded, (welded on either side of the wall membrane) to provide extra reinforcement for high loads. A-type, D-type and O-type are all water tube package boilers.
