Boiler Repair in Somersworth, NH
Fuel oil heats 51% of households in Somersworth, which puts this town among the places where a boiler is simply what a house has. The trade that services them is local and busy, and that is worth more in January than anything else on this page.
In brief
A boiler is an ordinary appliance in Somersworth rather than an unusual one: 51% of households heat with fuel oil. An oil-fired system is serviced annually rather than repaired when it stops, and the burner, the tank and the controls all belong to that appointment.

How Somersworth heats
In a town where oil is the norm, the useful question at the annual visit is not whether it passed but what the combustion numbers were, and whether they moved since last year. One reading is a snapshot; two are a trend, and a trend is what tells you a part is on its way out before it takes the heat with it.
| Households in Somersworth | Share |
|---|---|
| Fuel oil and kerosene | 51% |
| Gas — mains and bottled | 33% |
| Electricity | 11% |
| Wood, coal, solar or no fuel | 5% |
Across the 30 towns we cover in New Hampshire, 32% of households heat with oil. Somersworth sits about level with that.

The table counts what a household burns, not what burns it. A furnace and a boiler on the same fuel are one number here, and we do not pretend otherwise.
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
If a replacement is proposed, ask what ruled out the components. Circulators, controls, expansion tanks and relief valves are replaceable, and most faults are one of them rather than the vessel.
