Atmospheric vent water heaters rely on natural draft to move exhaust through a metal flue. They are common in older homes and are often the most affordable gas option. We inspect the existing vent for damage, proper slope and clearance. If the vent is undersized or corroded, we replace it. Proper draft is essential for safety.
Traditional Tank Gas Water Heater Installation in Rexburg
Many homes in Rexburg rely on traditional tank gas water heaters for their hot water needs. We specialize in installing these units, providing proper gas line connections, venting and water line hookups.

We also confirm correct pressure relief valve installation and seismic strapping where local code requires it for safety.

Direct Vent Gas Water Heater Installation in Rexburg
Direct vent water heaters draw combustion air from outside and vent exhaust through a sealed system. They are a good choice for tight utility rooms or interior closets. We install the vent kit through an exterior wall with proper clearances. Many direct vent models do not need electricity. They offer safe, dependable operation.

Installing a gas water heater involves working with natural gas lines, water lines and exhaust venting, which can be dangerous if not done correctly. Improper installation can lead to gas leaks, carbon monoxide poisoning or water damage. It is highly recommended to hire a licensed professional for safety and code compliance.
Choosing the right size depends on your household's peak hot water demand, determined by the number of residents and hot water fixtures. Our technicians will assess your needs during the consultation to recommend the right gallon capacity or flow rate for your Rexburg home.
Power vent units use a fan to push exhaust outside, while direct vent units use a sealed system that draws outside air. Both allow flexible placement compared to atmospheric vents.
Rusty water, leaks, pilot problems and slow recovery are common signs. If your heater is over 10 years old, replacement may be the smarter option.
It's recommended to have your gas water heater professionally serviced once a year. Regular maintenance can extend its lifespan, improve efficiency and catch potential issues before they become major problems, supporting safe operation.
Many jurisdictions require a permit for gas water heater installation. We pull permits when required and make sure the work passes inspection.
We install Rheem, A.O. Smith, Bradford White, Navien and Rinnai. We recommend models based on reliability, efficiency and warranty.
