HKL Plumbing offers electric tankless water heater replacement services in Hilo, HI.

Recirculation Tankless Upgrades in Hilo, HI
If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is popular in long single-story ranch homes.
Exterior Mount Tankless Units in Hilo, HI
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. Frozen pipes are essentially a non-issue for homes in Hawaii, since sea-level and most residential areas never get cold enough to freeze water lines. 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 easiest swap when the gas line is already sized correctly.
Navien Tankless Water Heater Replacement in Hilo, HI
Navien tankless water heaters are popular for their condensing technology, delivering high efficiency and performance.

Most municipal water in Hawaii comes from volcanic groundwater aquifers and is generally soft to moderate, so heavy scale is less of a problem than in many places. Scale builds inside tankless heat exchangers over time, so a correctly sized replacement with flush valves protects homes in Hilo, HI from early failures.

Frequently Asked Questions About Tankless Water Heater Replacement in Hilo
The cost of tankless water heater replacement in Hilo, HI 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.
HKL 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 order and install other brands based on your preference or home requirements.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, typically takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to additional plumbing, gas or electrical changes required for proper installation and venting.
With proper installation and regular maintenance, a new tankless water heater typically lasts 20 to 25 years. This is significantly longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in areas with hard water.
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.
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.
Common signs that your tankless water heater needs replacement include frequent error codes, inconsistent water temperature, reduced hot water flow or a complete lack of hot water. If your unit is over 15 to 20 years old and repairs are becoming common and costly, replacement is often the more economical choice.
New tankless water heaters usually come with a manufacturer's warranty on the heat exchanger, usually 10 to 15 years, and on parts, usually 3 to 5 years. HKL Plumbing also provides a warranty on our installation workmanship. We will go over all warranty details with you before your replacement so you understand your coverage.
