The Vitomax 200-WS is an oil/gas fired low pressure hot water boiler. It was specifically developed for the demands of commercial nurseries.

The Vitomax 200-WS benefits at a glance:

• Economical fuel consumption – boiler efficiency: 94%
• Three-pass boiler with low combustion chamber load (≤ 1.0 MW/m3) – clean combustion with low nitrogen oxide emissions
• No minimum heating water flow rate required – wide water galleries and large water content provide excellent natural circulation and a reliable heat transfer – simplified hydraulic connection
• No additional intermediate flow piece required. All necessary connections for a safety temperature of 110 ºC are already fitted to the boiler
• Low pressure drop on the hot gas side through convection heating surfaces with generously sized hot gas pipes
• The additional DHW circulation pipe in the lower boiler area (shunt pipe) is designed for the internal circulation of the boiler water providing an optimum heat distribution inside the boiler
• High operational reliability and a long service life are ensured through wide water galleries and large water content with excellent natural circulation and reliable heat transfer
• High level of serviceability through watercooled reversing chamber without lining plus large cleaning door – for reduced maintenance costs
• Load bearing cover on top of the boiler as part of the standard delivery – this simplifies the installation and maintenance and protects the thermal insulation against accidental damage
• Low radiation losses through 100 mm thick composite thermal insulation
• The Vitocontrol control panel enables the regulation of all boiler-specific control equipment
• Approval in accordance with the European Pressure Equipment Directive 97/23/EC or the Gas Equipment Directive 90/396/EEC
