Tankless hot water heater — Ann Arbor, MI
Last updated: September 24, 2026
What affects the price
Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.
About this service
A tankless unit heats water directly as it flows through the device instead of keeping a large reservoir hot. You should consider this upgrade if your household frequently runs out of hot water during showers or if you want to reclaim space in your utility closet. Because these units only heat water on demand, they are more efficient than traditional tanks.

After the tank is empty, briefly turn the water supply back on to rinse it before refilling and restoring power/gas.
How do I adjust a water heater thermostat?
Adjusting a water heater thermostat usually involves locating the control dial or buttons, often behind an access panel.
