Viessmann Vitomax HW – High‑Pressure Hot Water Boiler
High‑performance industrial high‑pressure hot water boiler delivering 0.35 to 20.0 MW, designed for flow temperatures above 110 °C, ultra‑high efficiency, and 100% hydrogen‑ready operation for future‑proof heating solutions.

Features

Powerful & Highly Efficient

Efficiency exceeding 95.5%, even at 100% load Designed for continuous high‑output industrial operation Delivers up to 20.0 MW regardless of fuel type Ideal for manufacturing plants and district heating systems

Hydrogen‑Ready & Fuel Flexibility

Approved for operation with up to 100% hydrogen Wide fuel compatibility, including: Hydrogen Natural gas Light fuel oil (EL) Heavy fuel oil (Mazut 100) Biogases and bio‑oils Animal fats Comparable NOx emissions when operating with hydrogen

Water‑Cooled, Low‑NOx Design

Water‑cooled burner entry point (no refractory concrete) Maintenance‑free burner entry over boiler lifetime Eliminates thermal NOx formation caused by refractory reflection Water‑cooled reversing chamber maximises energy recovery from flue gases

Low‑Stress & Long Service Life

Corner stays arranged in pairs reduce mechanical stress Optimised spacing between smoke tubes, flame tube, and boiler casing Minimal shear forces from thermal expansion Designed for long‑term, reliable operation

Easy Maintenance & Long Inspection Intervals

Multiple inspection and access ports Easy‑opening boiler doors Cleaning door at boiler rear Enables long inspection intervals and low operating costs
