The gas atmospheric water heater is the traditional, time tested design found in many Portland area homes. It relies on natural draft to vent exhaust up through a chimney or flue. Fontus installs, replaces, and services gas atmospheric water heaters across Portland and southern Maine.

An atmospheric unit burns gas and lets the hot exhaust rise naturally up a vertical vent or chimney, without a fan. It draws combustion air from the surrounding room. This simple design has been used for decades and works well where a suitable chimney or flue and adequate combustion air are available.

Benefits of an Atmospheric Water Heater

Atmospheric units remain popular for good reasons, including:

Lower upfront cost than power vent or direct vent models
A simple, proven design with no venting fan
No electricity required for venting
Straightforward replacement in homes already set up for it
Reliable performance when properly vented

Important Venting Considerations

Because an atmospheric unit relies on natural draft and uses indoor air for combustion, it needs a properly functioning chimney or flue and an adequate air supply. In very tight homes, draft can be an issue, and in those cases a power vent or direct vent unit may be a better fit. We evaluate your venting and home before recommending the right type.
