Navien Combi Boiler

Two-in-One Heating for Efficient, Modern Living

Navien combi boilers combine high-efficiency space heating and on-demand domestic hot water in one compact unit perfect for Ontario homes that want to save space without sacrificing performance. These wall-mounted boilers are ideal for both radiant heating and hydronic baseboard systems, delivering powerful performance and continuous hot water all year long.

With advanced condensing technology and Energy Star® certification, Navien combi boilers help reduce energy consumption while keeping your home warm and your showers hot even in the coldest months. These units feature smart control systems, quiet operation, and high turndown ratios for improved efficiency and comfort.

At Go Lime, we recommend Navien combi boilers for homeowners replacing older tank-and-boiler systems, or for new builds looking for a cleaner, more modern heating solution.
