The boilers that produce hot water in our homes can be powered by electricity (boiler) or gas.

They can also work in different ways depending on the models:

• In the case of Instant models , a flame heats a coil in which the water is made to pass by heating it instantly.

• In the Accumulation models instead the water enters a tank that is heated and kept in temperature in order to guarantee a hot water flow. Also in this case they can be electric or gas powered
