VITODENS 300

The combination of top technology:

The modulating MatriXcompact gas

burner and the proven stainless steel

InoxRadial heating surface guarantee a

standard efficiency up to 109%. This

reduces heating costs and protects the

environment.

Like all wall mounted condensing boilers

from Viessmann, Vitodens300 too is

equipped with a stainless steel

InoxRadial heating surface. And it

incorporates all advantages of the heat

transfer principle, of its design and its

high self−cleaning effect.

With its modulation range of 1:4, the

MatriXcompact gas burner saves in

terms of energy consumption and

emissions. Its extremely clean

combustion lets it perform substantially

better than the limits set for the "Blue

Angel".

Vitodens300 is equipped with automatic

flue gas adaptation. This constantly

adapts to changing conditions, for

example weather changes. And that

ensures permanently good combustion.

The MatriX−compact gas burner with its

quite combustion and the modulating,

electronic BUS−controlled pump

operating with reduced flow noise,

ensure a pleasantly quiet operation.

The combi version of Vitodens300 is

equipped with a comfort plate heat

exchanger. This delivers DHW at a

constant outlet temperaturewithout

delay.

*1Rated output for DHW heating.

*2Calculation values for sizing the flue gas system to EN13384.

Flue gas temperatures measured as gross values at 20ºC combustion air temperature.

The details for partial load refer to an output of 30% of rated output. Calculate the flue gas mass flow rate accordingly when the

partial load differs from that stated above (subject to the burner mode).

The flue gas temperature at a return temperature of 30ºC is decisive for sizing the flue gas system.

The flue gas temperature at a return temperature of 60ºC is used to determine the application range of flue pipes with maximum

permissible operating temperatures.

Variable speed heating circuit pump

The pump speed and therefore the flow

rate is relayed to the pump, and is set by

the control unit subject to outside

temperature and switching times for the

central heating or reduced mode via an

internal data BUS.

Individually match the minimum and

maximum speed plus the speed during

reduced mode to the existing heating

system using the control unit codes.

In the delivered condition, the minimum

pump capacity (code addressE7) is set to

30%, and the maximum pump capacity

(code addressE6) to 50% for 26kW or to

70% for 35kW.

Using the diagram, the flow rate can be

adjusted to the respective system

conditions.

Matching the flow rate of the circulation

pump to the individual system conditions

reduces the power consumption of the

heating system.
