Water Heater Repair in Delmar, DE
60% of households in Delmar 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
Knowing what Delmar burns is worth more over the telephone than any description of the symptom, and 60% of households there heat with electricity. House heating fuel predicts the water heater without proving it. An electric unit has two elements and two thermostats and no pilot that can go out.

What Delmar 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 | 26% |
| Electricity | 60% |
| Fuel oil and kerosene | 7% |
| Everything else | 8% |
Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 2,351 occupied housing units across Delmar.
Against Delaware as a whole, that is 27 points lower — worth knowing before assuming the state pattern applies here.
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
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. Knowing which of the two you own is the difference between a diagnosis and a guess.
After that it is the symptom that narrows things: nothing at all points one way, running out early another, and a puddle is the one to act on today.
