WHY WE RECOMMEND NAVIEN
Navien's combi boilers are a game-changer for Connecticut homes — you get both space heating and unlimited hot water from a single wall-mounted unit that's smaller than a suitcase. This eliminates the need for a separate water heater, frees up floor space, and simplifies maintenance. Their NaviLink Wi-Fi system lets you monitor and adjust your heating remotely. Navien's condensing technology extracts more heat from every therm of gas, making them one of the most efficient boilers you can install.
