200-T: The Future of 
Efficient Oil Heating
A new era of clean, intelligent, and cost-effective heating — 
engineered for homes that demand more.
The Challenge: Outdated 
Heating Systems
Energy Waste
Millions of homes still rely on aging boilers that burn fuel inefficiently, 
driving up energy costs and emissions.
Rising Bills
Outdated systems lose significant heat through flue gases — energy 
you pay for but never use to heat your home.
No Gas Network
Many rural and off-grid properties have no access to gas, making 
high-performance oil heating the only viable solution.
INTRODUCING

How Condensing Technology Works
Flue Heat Flue Gas Vapor Heat 
Lost Cooled Condenses Recaptured
By capturing the latent heat trapped in flue gases — energy that conventional boilers simply exhaust — the Vitorondens 
200-T converts nearly every joule of fuel into usable warmth.
Key Benefits of the Vitorondens 200-T
High Efficiency Fuel Flexibility
Up to 97% seasonal efficiency (Hs) and 103% net (Hi) — Compatible with all standard EL fuel oils, including bio-
minimizing fuel use without compromising comfort. blends up to 10% bio-components (EL A Bio 10).
Quiet Operation Smart Control
Optional external flue gas silencer ensures minimal noise — Vitotronic 200 control unit features a plain-text graphic 
ideal for installations near living spaces. display for intuitive, effortless operation.
Turning Waste Heat 
into Savings
In a conventional boiler, hot flue gases escape up the flue 
— taking valuable energy with them. The Vitorondens 200-
T intercepts this waste stream, cooling the gases until 
water vapor condenses and releases its latent heat back 
into the heating circuit.
Up to 35% more efficient than a standard 
atmospheric boiler — savings you feel in every 
bill.
