Port Huron asks a lot of a water heater
Winter nights here average 20°F from December through February, and that cold water coming into the tank is what your heater has to work against. Heat runs October through May in St. Clair County, eight months of the year, so the tank rarely gets a break to just sit and hold temperature.
Power is the other thing to plan around. Across Michigan, a third of households lost power for a full day or more in 2024, and the county has logged 13 winter storms and 82 damaging wind events over the past ten years. If a storage tank goes electric, an outage means no hot water until the power is back. A gas unit with a standing pilot keeps working through the outage itself. Whatever you install, it has to meet the federal minimum efficiency for its size, since the rule is set separately for each tank volume rather than as one number for every heater.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters have a limited service life, and once yours is old, the tank itself is more likely to fail than any part inside it. Rust colored water from the hot tap, a tank that's damp or weeping around the bottom, or water that never quite gets hot anymore are all signs the tank is on its way out. A puddle under the unit means the tank has started to leak, and that doesn't get better on its own. If yours is showing any of these signs, a contractor can tell you whether it's worth repairing or time to put in a new one.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says tankless is better. A tankless unit heats water only as you use it, so you don't pay to keep a tank hot all day, and it won't run out of hot water partway through a shower. It also takes up much less space than a tank. Against that, a tankless unit has different venting and gas or electrical needs than a tank, so switching usually means more work than a straight swap. A contractor who looks at your house can tell you what that involves for your setup.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of sitting on the floor, so where it goes in your house will likely change. Tankless units also have different venting requirements than a tank, and depending on the model, the gas line or electrical circuit feeding it may need to be upsized to deliver enough power to heat water on demand. None of this means the switch can't be done, it just means the installation is more involved than replacing a tank with another tank. A contractor can walk your house and tell you exactly what needs to change for the unit you're considering.
