Nine months of cold means nine months of work for a water heater
Winter nights in Lake County average 9°F from December through February, and homes here need heat September through May, nine months of the year. A water heater runs the other side of that same cold, warming groundwater to a set temperature every day it is on.
The federal minimum efficiency rule for a new tank is not one number. It is a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes each have their own minimum to meet even when they are the same type of heater. A contractor sizing a replacement has to check that number against the tank going in, not just the one coming out.

A heat pump water heater would save about $300 a year to run in South Dakota compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age first. Once a tank water heater gets old, a repair often just delays the same failure. Rust colored water from the hot tap, rust on the outside of the tank, or water pooling underneath mean the tank itself is failing, and a tank can't be repaired, only replaced. Popping or rumbling sounds point to sediment built up on the bottom, and while that alone doesn't mean replacement, it's often a sign of an older unit working harder than it should. If yours is older and starting to act up, get it looked at before it fails outright, since a tank that lets go can flood the space around it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether one is better than the other. A tankless unit heats water on demand, so you don't run out during back to back showers, and it takes up much less space than a tank. It also tends to last longer than a storage tank. Against that, a tankless unit costs more upfront and needs a contractor to check that your gas line and venting can support it, since it draws more than a standard tank when it's running. If your household regularly runs the tank dry, that's the clearest reason to consider switching.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That means no standby heat loss between uses, but it also means the burner has to fire at a higher rate than a tank's does, so the gas line sizing needs to be checked, not assumed to carry over. Venting changes too. A tankless unit typically vents differently than a tank and often needs its own dedicated line. The unit itself mounts on a wall instead of sitting on the floor, which frees up the space the old tank used. A contractor can tell you what your home's gas line and venting will need for the switch.
