Large boilers

Oil/gas fired low pressure hot water boiler Vitomax 100

Economical fuel consumption — boiler efficiency: 91.5% Boiler with reversing combustion chamber with low combustion chamber loading (?Ь 1.2 MW/m3) ЁC 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 єC are already fitted to the boiler Low pressure drop on the hot gas side through convection heating surfaces with generously sized hot gas pipes High level of serviceability through water-cooled reversing chamber without lining plus large cleaning door Low radiation losses through 100 mm thick composite thermal insulation 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 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

Oil/gas-fired low pressure hot water boiler Vitomax 300

High operational reliability and a long service life through multi-layered convection heating surfaces made from Duplex pipes Low energy consumption due to modulating boiler water temperature. Standard efficiency: 96 % (Hi). Standard efficiency improved by up to 10% through condensing technology with Vitotrans 300 stainless steel flue gas/water heat exchanger Low minimum return temperature of 38°C when using fuel oil and 45°C when using gas 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 єC are already fitted to the boiler Low pressure drop on the hot gas side through convection heating surfaces with generously sized hot gas pipes Low radiation losses through 120 mm thick composite insulation as well as water-cooled front and rear reversing chambers Three-pass boiler with low combustion chamber loading (1.2 MW/m3) — clean combustion with low nitrogen oxide emissions High level of serviceability through large cleaning door Load-bearing cover on top of the boiler as part of the standard delivery — this simplifies installation and maintenance Economical and safe operation of heating systems through the digital Vitotronic control system with communication capability. Standardised LON BUS for optional complete integration into building management systems Approval in accordance with the European Pressure Equipment Directive 97/23/EC or the Gas Equipment Directive 90/396/EEC
