The cost to install a tankless water heater in Ann Arbor ranges from $1,550 to $5,700, with most homeowners paying around $3,310. Your actual cost depends on several factors specific to your home and the Ann Arbor market.
Gas tankless units produce higher flow rates and work better for whole-home use but need gas line and venting upgrades. Electric units are simpler to install but may need a 200-amp electrical panel.
Higher gallon-per-minute ratings handle more simultaneous hot water demands — a family of four typically needs 8–10 GPM from a gas unit.
Gas tankless units need dedicated stainless steel venting to the exterior, which can add $300–$1,000 depending on the run length.
Many gas tankless units require a 3/4-inch gas line — if your existing line is 1/2-inch, an upgrade adds $200–$700.
Large homes may need two tankless units to meet peak hot water demand — point-of-use electric units for distant fixtures are a cost-effective supplement.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
Budget $54–$270 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Freeze protection is critical here. Budget for pipe insulation, heat tape on exposed runs, and deeper trenching below the frost line. Winter plumbing work typically costs more due to frozen ground conditions.
This project requires a licensed professional in Ann Arbor. Attempting tankless water heater installation without proper licensing can void insurance and create serious safety hazards.

Most tankless water heater installation projects in Ann Arbor take 1–2 days to complete. The timeline depends on project scope, contractor availability in the Ann Arbor metro area, and seasonal demand. Scheduling during Ann Arbor's off-peak season (typically fall and winter) can reduce wait times and may lower costs.
Tankless water heaters typically save $100–$200 per year on energy bills compared to a standard tank heater. The savings come from eliminating standby heat loss — the unit only heats water when you need it. Over a 20-year lifespan, that's $2,000–$4,000 in savings.
For a whole-home gas unit, most families need 8–10 GPM (gallons per minute). Calculate by adding the flow rates of fixtures you'd use simultaneously — a shower (2.5 GPM) plus a dishwasher (1.5 GPM) is 4 GPM. Add a safety margin for comfort.
