What Shelbyville winters do to a water heater
Groundwater coming into your house is cold from October through April, and on nights that average 26°F your water heater works harder to bring it up to temperature. That means longer burner cycles or the electric element staying on longer, and more wear on the thermostat and heating element or the burner assembly over those seven months.
Kentucky homes lost power for 24 hours or more in large numbers last year, and Shelby County has seen 11 winter storms and 50 damaging wind events over the past decade. A gas water heater with a standing pilot will keep working through an outage, but one with an electric ignition or an electric water heater will not come back on until the power does, and some units need the pilot relit by hand. If your water is running lukewarm or not heating at all after the lights flicker back on, that is usually why.

A new water heater would cut about $270 a year off hot water for a typical Kentucky home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself failing from the inside, where sediment builds up over years and corrodes the steel. Once the tank has a crack or a hole, no repair fixes it and the unit needs to be replaced. A leak can also come from a loose drain valve at the bottom or a failed inlet fitting, and those a contractor can often repair without replacing the tank. Shut off the water and power or gas to the unit and have someone look at it before you decide which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer hold the gas valve open once you let go. It can also mean a draft is blowing the flame out, or the pilot orifice is partly clogged. A thermocouple is a cheap part and a straightforward repair for a contractor. If you smell gas at any point, stop and call your gas utility before doing anything else.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. A failed igniter, a clogged inlet filter, a bad flow sensor, or mineral scale built up on the heat exchanger are all things a contractor can fix or clean without replacing the unit. Hard water speeds up that scale buildup, so a unit that's never been descaled is more likely to need service. If the heat exchanger itself has cracked, that's the one failure that usually means replacement instead of repair.
