If your water heater keeps running, you pay more and get less. The extra run time points to a problem you should solve quickly. This guide explains the common causes, what you can check today, when repair makes sense, and when an upgrade is the smarter move for your home in Southington CT.
Why your water heater keeps running and what it means.
A healthy system cycles on and off. When a heater runs all the time, heat is escaping or the unit is misreading water temperature. Tank models lose heat through the tank walls and piping if insulation is weak or sediment has built up inside. Electric elements and gas controls can fail and keep calling for heat. Thermostats can drift out of calibration. Small leaks force the heater to reheat again and again. Even a slow drip on the hot side will keep a tank reheating.
Simple checks you can do now
Look around the base of the heater for water. Check the hot and cold connections and nearby shutoff valves. Listen for constant hissing, bubbling, or crackling, which often signals heavy sediment. Put a hand near exposed hot water lines and the tank body to feel for wasted heat. Review the age of the unit. Most tanks last 8 to 12 years. If yours is older, long run time is common and efficiency is falling. Set the thermostat near 120°F. A higher setting forces longer cycles without adding comfort, and it increases energy use. For reference on safe settings and best practices, see the U.S. Department of Energy’s guidance on water heating.
When repair is the right move
If the heater is under 10 years old and in good shape, a targeted repair often solves the problem. A professional flush removes sediment so heat transfers faster. An anode rod replacement slows future corrosion. A faulty thermostat or heating element can be replaced. Gas control issues can be corrected and tested for safe operation. After repair, cycle times shorten, recovery improves, and bills drop.
When replacement makes more sense
Some systems are not worth the next repair. If the tank is past its expected life, shows rust at seams, or has repeated control failures, replacement protects your home and budget. A new high efficiency tank reduces standby loss and shortens each heating cycle. A tankless system eliminates storage loss and heats water only when you need it. Many homeowners choose tankless for steady hot water and lower energy use over time.

Prevent the problem from returning
Annual maintenance keeps run time under control. A full flush clears sediment. Temperature and pressure relief valves should be tested on schedule. Pipe insulation reduces heat loss at the tank and the first few feet of hot and cold lines. A quick check of the expansion tank, shutoff valves, and venting protects both performance and safety. If your home has hard water, pair your system with proper treatment. Cleaner water protects the heater and fixtures throughout the house.
