Ferroli Combi Boilers
Ferroli combi boilers ensure fast access to hot water from the mains water supply using a small sized wall mounted unit that are in general located in a kitchen or bathroom and tucked away within a cupboard. Ferroli combi boilers are energy efficient units with low running costs that are ideally suited to apartments and small to medium sized houses with 1 to 2 bathrooms. Ferroli combi boilers don't require hot water tanks or cylinders as a regular boiler or system boiler does therefore allowing Ferroli combi boilers to be installed at a lower price.
