Single-circuit gas heating boiler of high power with an open combustion chamber and a convenient electronic control system Viessmann KC4. It features relatively compact dimensions and impressive heat output (up to 72 kW). It is a mid-level model from the Viessmann Vitogas 100-F family of floor standing single-circuit boilers. The impressive power of this device is enough to organize heating of residential, office, household and commercial premises with a total area of up to 576 m2.

It is worth noting that the Viessmann Vitogas 100-F GS1D903 72kW boiler is designed for installation in non-residential premises with a free supply of fresh air, and for its safe operation, a full-fledged chimney system is required, which must meet a number of mandatory fire safety requirements and provide stable natural draft. Efficient heating of the coolant occurs in a durable cast-iron sectional heat exchanger (estimated service life — 15 years), the cast design of which is optimized for maximum heat transfer. Thanks to the use of an atmospheric pre-mix burner made of high-alloy heat-resistant steel, the boiler shows high energy efficiency and an efficiency of up to 92%. It can be paired with an external indirect heating boiler for hot water preparation.
