Technical catalogue: Specs, wiring diagrams, flue options, hydraulic schematics

Price list: Model codes, RRP, trade prices (often separate PDF)

Gas Condensing Boilers: High-efficiency boilers that use condensing technology to minimize energy consumption and reduce emissions.

Oil Condensing Boilers: Reliable and efficient boilers that burn oil to provide heating and hot water.

Solid Fuel Boilers: Boilers designed to burn solid fuels, such as wood and biomass, for a sustainable heating solution.

Hybrid Boilers: Combination boilers that integrate different heating sources, such as gas, oil, and solar, for optimal efficiency.

Commercial Boilers: Large-scale boilers designed for commercial and industrial applications.

Commercial Boilers

Why Use the Viessmann Catalogue?

Easy cross-comparison – Compare models side by side (output, efficiency, footprint).
Installation planning – Dimensions, clearances, and flue lengths are clearly shown.
Regulatory compliance – Meet ErP, Boiler Plus, or local efficiency standards.
System design support – Sections on buffer tanks, low-loss headers, and multiple heat sources.

Vitodens 300-W (Premium Modulation)

Target Audience: Large detached homes, light commercial.
Key Specs: Up to 99 kW. Cascade-ready (can link up to 16 units).
Why choose it: The turndown ratio is industry-leading (1:10). It can run as low as 1.9 kW, meaning it never short-cycles in summer or mild winter conditions.

Embracing the Future: Heat Pumps and Hybrid Systems While gas boilers remain prevalent, the Viessmann catalogue increasingly pivots toward electrification and renewable energy. The inclusion of the Vitocal series—air source and ground source heat pumps—signals the company’s strategic alignment with the "Energiewende" (energy transition). The catalogue positions these units not as alternatives to boilers, but as the successors to the throne of domestic heating. The Architecture of Warmth 5
