The Vitodens 100-W (B1HE / B1KE) is Viessmann Canada's wall-hung residential condensing boiler series: four heating sizes and two combi models from 8.5 to 199 MBH input, rated 95% AFUE, with WiFi built in and a 3.5-inch LCD display.
Series facts
95% AFUE on all models per the Canadian product page.
The Vitodens 100-W is a gas-fired wall-mounted condensing boiler with a modulating MatriX-Plus cylinder burner and an Inox-Radial stainless steel heat exchanger, per Viessmann Canada. Rated input runs from 8.5 to 199 MBH across the models, WiFi is built in for the ViCare app, and the boiler carries an adjustable 3.5-inch LCD control panel.
The series splits into heating-only and combi versions. B1HE models heat rooms only and are paired with an indirect tank for domestic hot water, while B1KE combi models add on-demand DHW through a plate heat exchanger: Viessmann Canada lists a continuous draw of 3.3 USG/min for the B1KE-120 and 4.7 USG/min for the B1KE-199 at a 77°F rise.
Viessmann Canada lists the series for natural gas or liquid propane with no mechanical fuel-conversion adjustment, zero clearance to combustibles, and multiple venting options with run lengths up to about 180 ft. Minimum fire drops to 8.5 MBH on the smallest model and the unit is approved for high-altitude operation up to 10,000 ft, which suits well-insulated Lower Mainland homes and basement mechanical rooms.

Services for Viessmann boilers
B1HE models are heating-only boilers and are paired with an indirect tank for domestic hot water. B1KE models are combis: they add on-demand DHW through an integrated plate heat exchanger, so no separate tank is needed.
Yes. Viessmann Canada lists natural gas or liquid propane with no mechanical fuel-conversion adjustment required. The published minimum inputs are for natural gas; propane minimums are set out in the installation manual (6167 818 - 22), and fuel setup is a gas-fitting task for a licensed contractor.
The B1HE/B1KE control displays F.xx fault messages for flame, pressure, temperature and component issues, plus P/S/A/I status messages. Boilers.ca documents the fault tables from Viessmann Canada's installation manual 6167 818 - 22 for this series.
