Electric boiler

Choosing the right type of energy to use to heat up your home and hot water can be a tricky decision. Oil and electricity must be considered the most convenient forms of energy. For those who don't mind spending a little time on their heating system then pellets and wood are excellent options in terms of heat and economy. Both pellets and wood are environmentally friendly alternatives, as they do not contribute to the green house effect.
