Product Information

VITOROND 200

The modular sectional cast iron design of

the Vitorond 200, V 2 allows for

problem-free transport into

difficult-to-access boiler rooms and permits

easy assembly.

The triple-pass design ensures clean,

low-emission combustion, while the

Eutectoplex heat exchanger surface

guarantees economical energy consumption,

high operational reliability and a long service

life.

The benefits at a glance:

HEutectoplex heat exchanger surface for high

operational reliability and a long service life.

The homogeneous structure of the

Eutectoplex special gray cast iron ensures

uniform heat transfer, minimizing stress

fractures and counteracting the formation of

condensate.

Shape and geometry of the cast iron

sections, excellent water flow characteristics

and uniform temperature distribution further

increase the level of operational reliability.

HProblem-free transport into

difficult-to-access boiler rooms due to

sectional construction and low weight of

individual sections.

HEfficient and environmentally friendly

operation due to modulated boiler water

temperatures.

Combustion efficiency up to:

- oil 88.1%

.....................................................

- gas 85.5%...................................................

Thermal efficiency up to:

- oil 88.0%.....................................................

- gas 85.4%...................................................

HLow-emission combustion through

triple-pass design.

HSimple, quick assembly of the individual

cast iron sections is achieved with a

double-groove seal fit system for the flue

gas passageways. The gasket seal is

secured in place by the double groove,

and therefore not subject to mechanical

stresses.

HProblem-free cleaning access facilitated by

a hinged (left or right) swing-open

combustion chamber door, allowing easy

access to all three heat exchanger passes

from boiler front, reducing side clearance.

HEconomical and safe operation of the

heating system with Vitotronic or

ekamatik digital boiler and heating

system control. Tailored to every

requirement, this control covers all known

control strategies and applications.

HEconomical and hygienic HW production

with indirect-fired Vitocell 100 steel or

Vitocell 300 stainless steel tanks.

Tanks may be combined into multiple-tank

batteries for applications requiring larger

quantities of hot water.

Boiler Base

The boiler must be installed on a levelled base or foundation, which must be

designed to carry the entire weight of the boiler, water fill, burner and attached

piping. To ease the installation of the individual sections, angle-iron or flat steel

may be incorporated into the concrete foundation. Surface width of steel strips

should be 4” / 100 mm.

Waterside Flow

The Vitorond 200 is designed for closed loop, forced

circulation, hot water heating systems only.

The recommended water flow rate through the Vitorond 200

is based on a temperature difference of between 20°F and

40°F / 11°C and 22°C. When a balancing valve is used for

proper balancing and water flow through the boiler, the valve

should be installed 5 pipe diameters from any fittings and 10

pipe diameters from circulation pumps to allow for laminar

flow.

The consulting engineer or contractor should review the

system design if more balancing valves are required to

properly balance the system.

Viessmann can supply TA (Victaulic) balancing valves upon

request. The balancing should be carried out by a certified

balancing firm prior to boiler start-up. Please contact

Viessmann for your closest certified balancing firm.
