Gas condensing boiler R3456 EVO

Models and output

Application possibilities

Value propositions

Models and output

The floor standing gas condensing

boiler R3456 EVO is available in 3

different ranges R3400 EVO, R3500

EVO and 3600 EVO. R3400 EVO is

the low condensing series. It consists of

10 models covering an output range

from 650 up to 1.900kW.

The R3500 EVO series consists of 9

models and covers an output range of

650 up to 1.600kW with an excellent

efficiency of 103,7%.The R3600 EVO

series offers maximum output with the

highest efficiency. 10 models cover an

output range of 700 up to 2.000kW with

an efficiency up to 109,1%.

Application possibilities

The gas condensing boiler R3456 EVO

is applicable for all central heating

systems built according to EN12828. In

cascade applications (max. 16 boilers

with LMS14 master/slave cascade

control) the R3456 EVO can cover

installations up to 32 MW .

Preferred applications are central

heating and sanitary hot water

production in hospitals, municipal, sport

facilities, industrial and educational

buildings.

Gas condensing boiler R3456 EVO

Technical description

Technical Description

The R3456 EVO is a fully modulating

condensing boiler. The control unit of

the boiler adapts the modulation ratio

automatically to the heat demand re-

quested by the system. This is done by

controlling the speed of the fan. As a

result, the whirlwind mixing system will

adapt the gas ratio to the chosen fan

speed, in order to maintain the best

possible combustion figures and there-

with the best efficiency. The flue gases

created by the combustion are trans-

ported downwards through the boiler

and leave at the back side into the

flue system.

The return water from the system en-

ters the boiler in the lower section,

where is the lowest flue gas tempera-

ture in the boiler. In this section con-

densation takes place. The water is

being transported upwards through the

boiler, leaving the boiler at the top

(burner) section. The cross flow work-

ing principle (water up, flue gas down)

ensures the most efficient results.

The LMS14 control unit can

control the boiler operation based

on:

 Fixed flow temperature;

 weather compensated

operation (with optional

outdoor sensor);

 0-10V external influence

(temperature or capacity) from

a building management

system.
