Boiler Repair in Severn, MD
In Severn, 7% of homes burn oil. A real minority — enough that the equipment is here, few enough that finding somebody who services it regularly is worth doing before you need one.
In brief
An oil-fired boiler is the exception in Severn: 7% of households heat with fuel oil and 41% with gas. The figure measures house heating fuel rather than the appliance, which is why the fuel and the make are both worth having before anybody is called.

How Severn heats
A small oil share often means older housing stock within a newer town — the houses that predate the gas main. That is also where the pipework and the emitters are oldest, and where the pattern of what is warm is most worth mapping.
| Households in Severn | Share |
|---|---|
| Fuel oil and kerosene | 7% |
| Gas — mains and bottled | 41% |
| Electricity | 50% |
| Wood, coal, solar or no fuel | 3% |
Across the 109 towns we cover in Maryland, 13% of households heat with oil. Severn sits 7 points above that.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 12,942 occupied housing units. B25040 is a fuel count. Hydronic and forced-air systems on oil are counted together, so read the share as "heats with oil" rather than "has a boiler".
Carbon monoxide
"Have the heating system professionally inspected and serviced annually to ensure proper operation" is CPSC’s wording, and it is a safety recommendation about combustion and venting rather than an efficiency suggestion.

Hot water or steam
Knowing whether the system is hot water or steam saves a visit. A steam boiler has a sight glass and a low water cutoff; a hot water boiler has a circulator, an expansion tank and a pressure gauge worth reading. Almost nothing that is true of one is true of the other.
DOE regulates them separately too, at slightly different AFUE minimums by fuel and type.

What to ask whoever comes
Ask where the flue terminates and what condition it is in. On an oil appliance the venting is as much a part of the annual check as the burner, and it is the part that is easiest to leave for next year.
