Vaillant Combi Boilers in Greater Vancouver
The world's best-selling wall-hung combi with OpenTherm compatibility
Vaillant's ecoTEC is the world's best-selling wall-hung combi boiler, pairing 140+ years of German engineering with OpenTherm smart-thermostat compatibility for maximum modulation savings.
What sets Vaillant apart is their deep commitment to OpenTherm compatibility and modulating control. Unlike brands that lock you into proprietary thermostats, Vaillant ecoTEC boilers work with any OpenTherm smart thermostat, allowing the boiler to continuously modulate its output down to as low as 20% of maximum — meaning your boiler runs longer at a lower, more efficient flame rather than cycling on and off. This alone can save 10-15% on annual gas consumption.
Our licensed gas fitters install, replace, repair, and service Vaillant ecoTEC combi boilers across Greater Vancouver. With ultra-quiet operation under 40 dB, built-in weather compensation on Exclusive models, and remote control via the sensoAPP, Vaillant is an outstanding choice for Vancouver homes where quiet, efficient heating matters.

This is not a DIY repair
Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
