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 ...

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.
In a residential setting, an electric boiler is often used as a backup to a house's heating system. During the colder months, heating and hot water is used more frequently. This type of boiler will provide additional heating and hot water to a home. [3] Some types of boilers aren't used for heating, but for other purposes.
It is the official goal of Ghana energy industry to have 10% of Ghana's energy mix come from renewable sources (not counting large-scale hydropower) by 2015 or at the very latest by 2020. [23] Ghana has Class 4-6 wind resources at locations of the high wind areas – such as Nkwanta, the Accra Plains, Kwahu and Gambaga mountains.

One of two electrodes is connected to the power supply, and the other one is grounded. As this configuration is similar in principle to a capacitor in an electric circuit, the plasma formed in this configuration is called a capacitively coupled plasma.
