Emergency Tankless Replacement in Roseville, MI
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 usually get a unit installed the day you call.

Residential Tankless Water Heater Replacement in Roseville
For homeowners in Roseville, upgrading to a tankless water heater offers significant benefits like endless hot water and reduced energy use.

That includes all necessary gas and water line adjustments and venting changes to meet current codes.
Exterior Mount Tankless Units in Roseville, MI
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. Draining outdoor spigots in the fall and keeping heat on in vacant homes prevent many of the burst pipes plumbers see each winter. 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.
Condensing Tankless Replacement in Roseville
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through inexpensive PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Humid summers bring condensation on cold pipes and damp basements, which can mask slow leaks. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth it.
Like-for-Like Tankless Swaps in Roseville
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the quickest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or stuck. Most like-for-like swaps are done in four to six hours.
Electric Tankless Water Heater Replacement in Roseville, MI
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice. CHV Plumbing offers electric tankless water heater replacement services in Roseville, MI. This often involves careful assessment of your home's electrical panel capacity, as these units require significant amperage. We make sure your new electric tankless unit is installed safely and effectively, providing on-demand hot water without the need for gas lines.
Gas Tankless Water Heater Replacement in Roseville
Many homes in Roseville rely on natural gas for water heating, and gas tankless units are a very efficient option.

We prioritize safety. All gas connections and combustion air requirements meet Michigan and local codes, heading off potential hazards and maximizing efficiency.

To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and accessible for our plumbers. If possible, clear a path to the installation site and keep pets or children away from the work area. We will handle draining the old unit and all other technical preparations.
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.

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 may require more extensive changes to gas lines, electrical or venting.
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.
Often yes, especially when converting from a tank. Many tankless units need three quarter inch gas pipe and a meter that can handle 199,000 BTU on top of your furnace, range and dryer.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail much sooner. Annual flushing makes the largest difference.
