Boiler Repair in Warwick, MD
With 32% of homes on oil, Warwick has a real oil minority rather than a token one. That usually means you have a choice of contractor, which is not true everywhere.
In brief
32% of homes in Warwick run on fuel oil against 32% on gas. The figure describes house heating rather than the appliance itself, but it is the best free indication of which kind of boiler a given street is likely to hold.

How Warwick heats
In a town split between fuels, the first useful fact is which one you have, because an oil boiler and a gas boiler are different machines to own. Oil has consumables and a tank; gas has neither.
The consequence is maintenance. Oil forces an annual appointment. Gas does not, and CPSC recommends one regardless.
| Households in Warwick | Share |
|---|---|
| Fuel oil and kerosene | 32% |
| Gas — mains and bottled | 32% |
| Electricity | 30% |
| Wood, coal, solar or no fuel | 5% |
Across the 109 towns we cover in Maryland, 13% of households heat with oil. Warwick is small enough that its own oil share carries too wide a margin of error to place against that figure, so we do not.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 677 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
The reason CPSC ties annual servicing to CO is that the failure is in the combustion or the venting rather than in the fuel. A system that heats perfectly well can be venting badly, and nothing inside the house will tell you except an alarm.

Hot water or steam
Hot water or steam is the first thing a contractor will establish and the first thing worth knowing yourself. Steam systems have one pipe or two to each radiator, no circulating pump, and a sight glass on the boiler showing the water level. Hot water systems have a pump, a pressure gauge and an expansion tank.
DOE sets different efficiency minimums for the two — 84% against 82% on gas, 86% against 85% on oil — so the distinction reaches the paperwork as well as the pipework.

What to ask whoever comes
Ask whether the appliance is hot water or steam, and what its AFUE is. DOE’s minimums run 82 to 86 percent depending on fuel and type, so those two facts decide what a like-for-like comparison even means.
