It’s important to buy the most efficient boiler you can, close to 90% (check sedbuk.com), in an appropriate size. Aim for at least a five-year warranty. The boilers that work to the highest standard are the fan-assisted room-sealed type — i.e. it takes air from outside the building and combustion products are forced out using a fan.
The most common type of electrode boiler pumps water from the lower part of the vessel to an internal header that has nozzles that allow the water to flow to electrodes. Generally the working pressure is maintained at 10 bar. If more pressure is needed (more steam) the controls speed up the pump to increase flow through additional nozzles.
Advantages of Electric Boilers. High efficiency As electric boilers don’t need to burn fuel to produce heat they don’t lose energy through waste gases or flues. In many cases this results in efficiency rates of 99% compared to 89 – 95% for most gas boilers.
