Emergency Tankless Replacement in Novi, 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 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 as soon as we arrive. Call (810) 380-5918 anytime your tankless quits.
Condensing Tankless Replacement in Novi
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 low-cost 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 musty 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 the price.
Gas Tankless Water Heater Replacement in Novi
Many homes in Novi rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes careful inspection of your existing gas lines, proper sizing of new gas lines if needed, and secure venting to the outdoors. We prioritize safety. All gas connections and combustion air requirements meet Michigan and local codes, preventing potential hazards and maximizing efficiency.
Tank to Tankless Conversions in Novi, MI
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.

Yes, you can certainly replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners seeking better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation essential for safety and performance.
To extend the life and efficiency of your new tankless water heater, regular maintenance is crucial, especially in areas with hard water. This usually involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. CHV Plumbing offers maintenance plans to help keep your unit in top condition.
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.
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 sensible choice.
