Before you hire
Tankless water heaters in Metro Detroit: what to know
A tankless water heater heats water only when you open a tap, so it never runs out and takes a fraction of the space of a tank. Most homes use a gas unit mounted on a wall. The install often needs a larger gas line, new PVC venting through the wall, and a dedicated electrical outlet.
Metro Detroit water is moderately hard, so ask about a yearly flush or a scale filter to protect the unit. Switching from a tank usually takes most of a day. Compare with a standard water heater installation.
What a proper job includes
- Removal of the old tank
- Wall-mounted tankless unit sized to your hot water demand
- Gas line sized for the unit, leak tested
- New venting through the wall or roof
- Service valves for easy flushing
- Permit and inspection
What drives the price
- Gas or electric model and its size
- Gas line upsizing from the meter
- Venting route and length
- Electrical outlet or circuit
- Scale filter or water softener
- Utility rebates

Permits and licensing in Michigan
Plumbing work in Michigan is done by a licensed plumbing contractor with a plumbing permit for new installs and replacements. A homeowner who lives in a single-family home may pull a permit for work they do themselves. Check the license on the LARA lookup. In Detroit, permits and inspections go through BSEED; suburbs use their own building department.

How to compare quotes
- Ask what flow rate your home needs for showers at the same time.
- Ask whether the gas meter and line can supply the unit.
- Confirm venting and permit are in the quote.
- Ask about yearly flushing and the warranty terms.
