Exterior Mount Tankless Units in Tulsa, OK
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 break down plastic covers and wiring over time. Before a cold front, homeowners around Tulsa should disconnect hoses, cover outdoor spigots and let faucets trickle overnight. 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 Tulsa
The cost of tankless water heater replacement in Tulsa, OK 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 detailed, upfront quote after a thorough assessment of your home.
Yes, tankless water heaters are generally more energy-efficient than traditional tank models. They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to real savings on your utility bills over time, especially in homes with varying hot water usage.
Most jurisdictions in Oklahoma require a permit for water heater replacement, especially when gas piping or venting changes. We take care of permits where they are required.
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.
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 on your behalf.
JBK Plumbing installs and replaces all major trusted 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.
DIY tankless water heater replacement is generally not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to dangerous gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like JBK Plumbing.
Frequent error codes, fluctuating temperature, water leaking from inside the cabinet and a unit older than 15 years are common signs. If the heat exchanger is leaking, replacement is usually the better value.
