Exterior Mount Tankless Units in High Point, NC
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. Hard freezes are uncommon along the coast but happen most winters in the mountains, where pipes in crawlspaces and outside walls need protection. 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 shield the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.
Commercial Tankless Replacement in High Point
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they share the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is flexible, so we can work after hours and keep your business open. We also set up a descaling schedule suited to your water usage.
Emergency Tankless Replacement in High Point, NC
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can often get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak on arrival. Call (980) 364-4317 anytime your tankless quits.

Frequently Asked Questions About Tankless Water Heater Replacement in High Point
A like-for-like gas tankless replacement usually runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before we start any work.
Often yes, especially when converting from a tank. Many tankless units need three quarter inch gas pipe and a meter that can supply 199,000 BTU on top of your furnace, range and dryer.
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.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually 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 extra plumbing, gas or electrical changes required for proper installation and venting.
A standard tankless water heater replacement usually takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion can call for more extensive changes to gas lines, electrical or venting.
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 frequent and costly, replacement is often the more economical choice.
New tankless water heaters typically come with a manufacturer's warranty, which usually covers the heat exchanger for 10 to 15 years and parts for 3 to 5 years. HFN Plumbing also provides a labor warranty on our installation work for your peace of mind. We will go over warranty details for your chosen unit during your consultation.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has strengths, and we recommend based on your flow needs, venting options and budget.
