Scalding one minute, lukewarm the next? On electric heaters, the thermostats call the shots — and when they fail, comfort and safety both suffer. Call (833) 713-2101 for fast thermostat diagnosis and replacement.
Electric storage heaters carry two thermostats — upper and lower — working as a team. When one sticks or drifts, you get the classic symptoms: water hot enough to scald, then barely warm; a tripped reset button; or a heater that runs constantly and spikes your electric bill.
Faulty thermostats aren’t just uncomfortable — overheating stresses the tank, the T&P valve, and every downstream fixture. We test both thermostats under load with proper meters rather than guessing, then replace the failed unit with a correctly rated match and recalibrate the setpoint to a safe 120°F.
Because thermostat failure often travels with sediment-baked lower elements, we inspect the full electric system during the visit — one trip, complete answer.
Call (833) 713-2101 — describe what you see and we’ll give you a straight answer on the spot.
