Electric steam boilers are more sustainable than their cousins the more traditions fire heated boiler. They are more sustainable because they do not require as much energy to be put into them for efficient operation at capacity. This is because there is not a lot of energy lost when the transfer of heat from the heating apparatus to the water occurs, unlike traditional fire heated boilers where there is a substantial amount of energy loss because of the way that the flames must be kept lit and healthy.[2] Marketability: Electric steam boilers are much more marketable then regular boilers to people that would use them for small applications because it can be sold with the idea that it is green and much healthier for the environment that buying and operating a fire heated boiler.[3]
