Simple - Reliable - Efficient
A dual fired combi the SFC provides not only high-efficiency space heating, but unrivaled domestic hot water efficiency too. We call this ‘Double HE’. The secret lies in our patented two-in-one heat exchanger that ensures optimal heat transfer and minimal heat loss.
Flue gases are condensed with both space heating and domestic hot water production ensuring heat extraction to the fullest extent possible.
The SFC assures you unrivaled high-efficiency and economical operation year in, year out.
