Exterior Mount Tankless Units in Rexburg, ID
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can wear out plastic covers and wiring over time. Frost reaches deep into the ground in colder areas, so water and sewer lines need to be buried safely below the local frost line. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to guard the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.

Frequently Asked Questions About Tankless Water Heater Replacement in Rexburg
The cost of tankless water heater replacement in Rexburg, ID typically ranges from $3,000 to $6,000, depending on the unit's capacity, brand, complexity of installation, such as converting from a tank model, and any necessary electrical or gas line upgrades. This price usually includes the unit itself and labor. We provide a written, upfront quote after a thorough assessment of your home.
We do not recommend it. Gas line sizing, venting clearances and combustion testing require training, and improper installs can void the warranty or create carbon monoxide hazards.
A direct swap usually takes four to six hours. A tank to tankless conversion with new gas and venting usually takes a full day.
HNV Plumbing installs and replaces all major reputable brands of tankless water heaters. Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance. We can also source and install other brands based on your preference or home requirements.
Most jurisdictions in Idaho require a permit for water heater replacement, especially when gas piping or venting changes. We take care of permits where they are required.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit for you.
To extend the life and efficiency of your new tankless water heater, regular maintenance is key, especially in areas with hard water. This typically involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. HNV Plumbing offers maintenance plans to help keep your unit in top condition.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has its own strengths, and we recommend based on your flow needs, venting options and budget.
