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 IBC 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. IBC SFC 199-1 Superflow Boiler assures you unrivaled high-efficiency and economical operation year in, year out
Materials of Construction – From its 439 or 316 Ti, high grade stainless steel heat exchanger/pressure vessel to its FeCrAlloy™ mesh burner, IBC has researched and sourced the best materials available to ensure that each boiler will operate as efficiently as possible while providing durability over the long term.
Top Quality Construction – Gas valves, combustion fans, controls – all of the components necessary to create a chain that will convert a fuel gas into reliable, efficient and comfortable heat for your home.
Ideal Combustion – The first link in the chain is to convert your fuel into heat in the most efficient way possible. Using precise fuel-air mixing and advanced burners and combustion control, IBC HC Series boiler squeeze every penny out of your energy dollar.
Deep Modulation – IBC boilers can precisely match our burn rate to the heat required by your system – saves fuel, saves wear and tear.
Efficient Heat Recovery –  boiler runs cool when it can and only ramps up to higher temperatures when specific loads require it (usually a small percentage of the heating season). IBC creative control methods ensure that heat is distributed only to those loads that need it at the time – more energy savings.
Advanced Diagnostic Features – intuitive and easy control set-up as well as unique system operation logging help you set up the boiler for optimum efficiency, and then maintain it, in whatever system it is connected to.
