Water heater expansion tank — 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
An expansion tank is a small auxiliary tank installed on the water line to handle pressure fluctuations as water heats and expands. If your plumbing system is closed, this tank prevents excess pressure from damaging your water heater or pipes. You need one if your local building code requires it or if you have high water pressure issues. Exact pricing confirmed free on the call.
Frequently asked in Ann Arbor
What are the risks of not flushing a water heater?
Not flushing a water heater can lead to significant problems. Sediment builds up at the bottom of the tank, reducing efficiency and potentially causing damage to the heating element. This buildup can also lead to rust and corrosion, shortening the lifespan of your unit. In severe cases, it can cause the tank to fail entirely, resulting in leaks and costly water damage. Regular flushing is essential maintenance.
How can I make my water heater more energy efficient?
To make your water heater more energy efficient, consider several options. Insulating the tank and hot water pipes can reduce heat loss. Lowering the thermostat setting to 120°F is also recommended. Regularly flushing the tank removes sediment that hinders heating. Upgrading to a newer, Energy Star certified model, such as a heat pump or tankless water heater, offers the greatest efficiency gains. Proper maintenance is key.
What are common gas water heater issues?
Common issues with gas water heaters include ignition problems, where the pilot light won't stay lit or the burner won't ignite. You might also experience inconsistent water temperature or a lack of hot water. Strange noises, like popping or rumbling, often indicate sediment buildup. Gas leaks are a serious concern, so any smell of gas requires immediate professional attention. Regular inspections are recommended.

What is involved in tankless water heater repair?
Tankless water heater repair can involve diagnosing issues like reduced hot water flow, error codes, or ignition failures. Mineral buildup in the heat exchanger is a common problem that requires descaling. The unit's sensors and igniter may also need attention. Professional technicians have the specialized tools and knowledge to safely and effectively repair these complex systems. Regular maintenance can prevent many repair needs.
What is the average cost for tankless hot water heater installation?
The average cost for tankless hot water heater installation varies significantly. Factors include the size and brand of the unit, as well as any necessary modifications to your home's plumbing, venting, or electrical systems. Professional installation is crucial for safety and efficiency. Getting multiple quotes from reputable local companies is the best way to understand the potential costs for your specific situation.
What is an 'on demand' water heater?
An 'on demand' water heater, also known as a tankless water heater, heats water only when you need it. Unlike traditional tank heaters that continuously heat and store water, these units activate when a hot water faucet is opened. This provides an endless supply of hot water and can be more energy-efficient. They are a modern solution for consistent hot water.
