Water Heater Repair in Sullivan, NH
65% of households in Sullivan heat with fuel oil. 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
In Sullivan the dominant heating fuel is fuel oil, at 65% of households, which narrows what can be wrong before anybody opens a panel. It measures house heating, so it predicts the water heater rather than reporting it. With oil heat the burner is a serviced appliance, not a part you swap.

What Sullivan runs on
Oil is clearly ahead here. Where the house heats water off the boiler rather than in a standalone tank, losing hot water in summer often means the boiler is not firing for domestic demand at all.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 10% |
| Electricity | 4% |
| Fuel oil and kerosene | 65% |
| Everything else | 21% |
US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 279 occupied housing units in the ZIP code areas that cover Sullivan.
The New Hampshire average is 25 points lower, so the state figure would mislead you about this town.
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.
Propane rather than mains gas
More households here run bottled or tank propane than mains gas, which changes two things: propane burners use different orifices from natural gas, and a tank that has run dry produces a no-hot-water call that mains gas can never produce.
Bottled and tank gas accounts for 9% of households here against 1% on mains gas.
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. Work out which kind you have before you call, and the call gets much shorter.
Next comes what it is actually doing. A rumbling tank is sediment; a short supply usually names the failed part; a leak decides itself.
