Customers
Why Choose CHV Plumbing for Tankless Water Heater Replacement in Grand Rapids, MI?
Well water across much of the state tends to be harder and often carries iron, which stains sinks and clogs aerators. Hard water is rough on tankless heat exchangers, and many early failures trace back to scale and skipped flushing. We size, install and set up each replacement so it holds up to your local water supply.
- Scale Protection, Every install includes isolation valves so the heat exchanger can be descaled without cutting into the pipes.
- Increased Lifespan, Modern tankless water heaters often last twice as long as conventional tank models, offering a better long-term investment.
- Right-Sized Units, We calculate gallons per minute and temperature rise for your fixtures instead of estimating from square footage.

Tank to Tankless Conversions in Grand Rapids, 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 usually need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate 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.

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.

Frequently Asked Questions About Tankless Water Heater Replacement in Grand Rapids
The cost of tankless water heater replacement in Grand Rapids, MI usually 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 needed electrical or gas line upgrades.

Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance.

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.
A standard tankless water heater replacement typically 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.
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 additional plumbing, gas or electrical changes required for proper installation and venting.
With proper installation and regular maintenance, a new tankless water heater usually lasts 20 to 25 years. This is much 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.
Repeated 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.
A direct swap usually takes four to six hours. A tank to tankless conversion with new gas and venting typically takes a full day.
