Cascade System 2x Vitodens 200-W 99 boilers

Description

Cascade System 2x Vitodens 200-W 99 Viessmann boilers

Installation consisting of 2 wall-mounted boilers Vitodens 200-W B2HA of 99 kW,
operating on the principle of condensation with cylindrical modulating burner with Lambda Control Pro and Inox-Radial heat exchange surface

The boiler has a blower and works with forced draft
Boiler components: Vitotronic 100 digital automation, self-diagnosis system and digital display
A hot water boiler (eg Vitocell-V 100) must be fitted for hot water preparation.
The circulation pump and the expansion vessel will be chosen separately depending on the installation configuration
The delivery set includes: automation for control in Vitotronic 300-K cascade (type MW2B) with external sensor and hydraulic cascade.
Flue gas accessories (collector 7311995) with a diameter of 125 mm cost separately (824 euros). Maximum pipe length = 12 m
Total thermal power = 2x 99 kW = 198 kW (round trip 50 / 30oC)
