                     The Evolution of Warmth
Mastering Oil Condensing Technology with Viessmann
The Hidden Crisis in 
Your Basement
Aging Infrastructure
Millions of heating systems are over 25 years old — operating 
far below modern efficiency standards.
Wasted Energy
Conventional boilers exhaust hot flue gases directly outdoors, 
losing significant heat with every cycle.
Money Up the Chimney
You are literally sending potential energy — and your money — 
up the chimney with every heating cycle.
THE BREAKTHROUGH
The 
Condensing 
Breakthrough
Conventional boilers deliberately 
avoid condensation to prevent 
corrosion — but in doing so, they waste 
enormous amounts of energy.
Viessmann reverses this logic: we 
actively seek condensation. By 
capturing the latent heat of water 
vapor in flue gases, we unlock a 
massive secondary energy source that 
traditional systems ignore entirely.
98% Efficiency
Transforming almost all fuel oil into usable heat — a direct result of 
the Vitoladens heat exchanger design.
Maximum Fuel Lower Carbon 
Conversion Footprint
Near-total combustion Fewer emissions per unit of 
efficiency means less oil heat delivered to your home.
burned for the same warmth.
Reduced Fuel Costs
Significant savings on every heating bill, year after year.
ENGINEERING EXCELLENCE
Stainless Steel 
That Lasts
Condensate produced during operation is 
acidic and corrosive — a challenge that 
destroys standard materials over time.
Viessmann utilizes high-grade, acid-
resistant stainless steel in all heat 
exchanger components, ensuring structural 
integrity and long-term performance under 
demanding conditions.
10-Year Guarantee on all heat 
exchangers — peace of mind 
built into every unit.
Future Fuels Ready
The energy transition is underway. Viessmann ensures your investment today 
remains relevant for decades to come.
