Instead of being run on natural gas, these boilers are run directly on electricity. Encompassing a 99.8% efficiency rate and holding compact design without the need for cylinders, electric boilers are an essential addition to the modern, progressive home. Moreover, you will not experience heat loss through gaseous waste products via chimneys/flues such as carbon dioxide. This is because fossil fuels are not always burned, in comparison to oil and gas, to produce heat. As well as having the environment in mind, your money is also held back to save!
