Tankless Water Heater Installation in Vancouver, BC

Endless Hot Water. Lower Bills. Less Space.

Tankless water heaters — also called on-demand or instantaneous heaters — heat water only when a tap is opened. There is no storage tank slowly losing heat around the clock. The result is an endless supply of hot water and energy savings of up to 40% compared to a conventional tank model.

AceComfort is a certified installer for Navien — Canada's best-selling tankless brand — as well as Rinnai, Bosch, and Noritz. We handle everything: proper gas line sizing and upgrading, concentric venting, permits, and the FortisBC rebate application.

A tankless unit typically mounts on the wall and frees up significant mechanical room space. For Vancouver homes undergoing renovation, building new, or simply replacing an aging tank, this is one of the most popular and sensible upgrades available.
