Boiler Repair in Greenwood, DE
Greenwood splits its heating: 20% on oil, 13% on gas. Both feed boilers, and the two are different machines to own.
In brief
Fuel oil heats 20% of homes in Greenwood, a substantial minority alongside gas at 13%. Which one a property burns decides the trade as much as the fault does, because an oil burner is a serviced appliance and a gas boiler is a different machine with different controls.

How Greenwood heats
With the town divided, the thing that does not divide is the physics. Every hydronic system is a closed loop under pressure with an expansion tank and a relief valve, and the gauge tells you about all three whatever is burning underneath.
| Households in Greenwood | Share |
|---|---|
| Fuel oil and kerosene | 20% |
| Gas — mains and bottled | 13% |
| Electricity | 58% |
| Wood, coal, solar or no fuel | 9% |
Across the 32 towns we cover in Delaware, 10% of households heat with oil. Greenwood sits 22 points above that.

Whether it feeds a boiler or a warm-air furnace is not in the table, and no published figure at this geography settles it.
Carbon monoxide
Carbon monoxide has no smell and no color, which is why the alarm matters more than your own senses do. CPSC recommends alarms on every level and outside sleeping areas, and an annual professional inspection of the heating system whatever it burns.

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 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.
