IBC SFC 199-1 Combi Boiler

A dual fired combi boiler 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.

DigelAir has established itself as Ontario’s trusted boiler wholesaler, providing a wide range of IBC boilers to contractors and businesses. With a strong reputation for reliability, competitive pricing, and exceptional customer service, DigelAir is the go-to source for high-quality IBC boilers in the region.
