What a Troy winter asks of your water heater
Winter nights here average 17°F from December through February, and the water coming into your house is that cold too. A new water heater has to bring that water up to temperature from a lower starting point than most of the country deals with, and it does that work eight months a year, October through May.
Power is the other thing to plan around. Rensselaer County has had 38 winter storms and 301 damaging wind events over the past ten years, and statewide, 11% of households lost power for a day or more in 2024. A gas water heater with a standing pilot keeps running through an outage. One with electric ignition will not fire until power is back. On sizing, the federal efficiency minimum is not one number for all tanks. It is set by the tank's rated volume and the household's draw pattern, so the right minimum depends on the size you need.

- How do I know it's time to replace my water heater?
- Age and how it is failing are the two things to look at. Most tank water heaters last a decade or more, and once one is old and starting to act up, a repair often just buys a little time before the next problem. Rusty water, a tank that is wet or rusted on the outside, or water that never gets as hot as it used to are signs the tank itself is going, not just a part inside it. A leak at the tank means it needs to be replaced now, since a tank does not get repaired once it is leaking from the steel itself.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water only when you run a tap, so it does not hold a limited supply the way a tank does, and you will not run out partway through a shower. It costs more to install than a tank of the same capacity, and a contractor needs to check your gas line and venting, since tankless units often need different sizing than what is already there. If your current tank works fine and fits your household, there is no mechanical reason you have to switch.
- What changes when you install a tankless water heater?
- The biggest change is that you get hot water on demand instead of from a stored supply, so as long as the unit is sized for your household, you will not run out. The install itself is different from swapping one tank for another. A tankless unit often needs a larger gas line to supply enough fuel for the burner to heat water quickly, and it needs its own vent designed for that unit rather than reusing the old tank's vent. It also needs a power source for its ignition and controls, even though it runs on gas. A contractor will look at your gas line, venting, and where the unit will go before pricing the job, since those details change from house to house.
