Water Heater Repair in Westminster, MD
51% of households in Westminster 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
Westminster runs on electricity: 51% of households heat that way, and that single fact rules most of the possible water heater faults in or out. The figure covers house heating rather than the tank. Electric heaters fail at an element or a thermostat, and nothing else is in the running.

What Westminster runs on
A split town with electricity ahead. Since the two heater types fail differently, that average does not narrow much on its own.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 24% |
| Electricity | 51% |
| Fuel oil and kerosene | 18% |
| Everything else | 7% |
US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 23,016 occupied housing units in the ZIP code areas that cover Westminster.
That sits 26 points lower than the Maryland average, which is why we publish the town figure rather than the state one.
Read that as a strong indicator rather than a measurement of water heaters. The Census counts what heats the house; what heats the water usually follows it, and occasionally does not.
Which one do you have
Check for a flue. Gas heaters vent; electric heaters have nothing to vent and carry element access panels on the side instead. Knowing which of the two you own is the difference between a diagnosis and a guess.
Then match what you are seeing: cold from the start, hot then cold, banging and popping, or a leak.
