Water Heater Repair in Hanover, MD
50% of households in Hanover heat with electricity. That is the strongest free clue to what kind of water heater is in your basement, and it decides which faults are even possible.
Answer first
Most households in Hanover heat with electricity — 50% of them — which is the strongest free clue to what stands in the basement, though the figure counts house heating rather than the water heater itself. Electric heaters fail at an element or a thermostat, and nothing else is in the running.

What Hanover runs on
The town divides, electricity in front. What your own tank burns is still the first question worth answering.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 45% |
| Electricity | 50% |
| Fuel oil and kerosene | 2% |
| Everything else | 3% |
US Census Bureau, American Community Survey, table B25040, 2023 5-year release. The universe is 9,297 occupied housing units in and around Hanover.
On gas, Hanover is close enough to the Maryland figure that the difference is inside the survey’s margin of error — so the state pattern is a fair guide here, which is not true everywhere.
That figure is house heating fuel, not water heater fuel. They correlate strongly, because the same gas line generally serves both, but the Census does not publish the second one and we are not going to pretend it does.
Which one do you have
Not sure which you have? A metal flue rising off the top is a gas heater. Two small access panels on the side and no flue is an electric one. The fuel decides the fault list, so start there rather than with the symptom.
With the fuel settled, read across to the symptom: none, not enough, noise, or water where it should not be.
