Vitodens 100-W, WB1B Technical Data

Product Information

General

Equipped with a Viessmann stainless steel heat exchanger

for lasting performance and reliability and a modulating

MatriX cylinder gas burner, the Vitodens 100-W wall-

mounted condensing boiler is the perfect combination of

value, quality and Viessmann technology.

The benefits at a glance:

Outstanding efficiency

of 94.0 % A.F.U.E. on all models.

Lasting performance

with Viessmann-made SA240 316Ti stainless steel

Inox-Radial heat exchanger constructed to ASME

Section IV and CSA B51.

Low-emission

with fully-modulating stainless steel MatriX cylinder

burner. Factory calibration eliminates adjustments in

the field.

< 29 ppm NOx (at 3% O2)

< 40 ppm CO (at 3% O2)

Control variety

Integrated boiler control interfaces with any level of

external control - from room thermostat to outdoor

reset and more.

Compact, lightweight wall mount design

and zero clearance to combustibles make it a great

choice for limited-space installations.

Extremely quiet operation

quieter than most refrigerators.

< 50 dBA [at 3.3 ft. (1 meter)]

Easy installation, service and maintenance

with all pipe connections located at the bottom

and serviceable components (including electrical

connections) easily accessible from the front.

Multiple venting options

- Horizontal or vertical sealed combustion

coaxial, PP(s) vent system (Viessmann supplied).

- Horizontal, vertical or hybrid sealed combustion

double-pipe CPVC vent system (field supplied).

- Horizontal or vertical single pipe CPVC vent system

(field supplied).

- Horizontal or vertical single or double pipe PP(s),

flexible vent system (Viessmann supplied).

Suitable for high altitude levels

of up to 10,000 ft. (3,000 m) without deration.

Built-in automatic frost protection

allows boiler to be shut off for an extended period

of time while protecting it against freeze-up.

Reliable on demand hot water

with an optional CombiPLUS kit (no DHW tank required).

- Plate type heat exchanger

- Built-in diverting valve

- Built-in Grundfos 3-speed pump

- Built-in flow sensor

- Built-in temperature sensor

- Supplied with a pressure relief valve rated at 150 psi

Note: Check the boiler rating plate on the Vitodens 100-W,

models WB1B-26 or WB1B-35 to ensure it states

compatibility with the CombiPLUS kit.

Boiler minimum clearances

Dimensions

Recommended minimum boiler and CombiPLUS Kit

clearances to combustibles

AL = Alcove

CL = Closet

*1Refer to the Installation Instructions

of the Vitodens Venting System

for details.

Note: The Vitodens 100-W boiler has passed the zero

inches vent clearance to combustibles testing

requirements dictated by the boiler latest

Harmonized Standard ANSI Z21.13. CSA 4.9.2007

and therefore is listed for zero clearance to

combustibles when vented with a single-wall special

venting system (AL-29-4C material) or UL/ULC-listed

CPVC/PP(s) gas vent material. The zero inches vent

clearance to combustibles for the Vitodens 100-W

boiler supercedes the clearance to combustibles

listing that appears on the special venting system

label.

Viessmann supplied 7” flex piping connection fittings.

Shown is the maximum distance between the boiler
