Boiler Repair in Exeter, NH

In Exeter, 33% of homes burn oil for heat. Enough that a contractor who works on boilers is findable, not so many that everyone assumes you have one.

In brief

33% of homes in Exeter run on fuel oil against 46% 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.

BoilerBridge is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no work, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

How Exeter heats

Federal efficiency minimums differ by fuel: DOE sets 84% AFUE for gas-fired hot water boilers and 86% for oil-fired hot water, with steam units slightly lower. So the two fuels are not held to the same standard, and a like-for-like comparison of quotes has to account for that.

Fuel oil and kerosene	33%
Gas — mains and bottled	46%
Electricity	14%
Wood, coal, solar or no fuel	6%

Across the 30 towns we cover in New Hampshire, 32% of households heat with oil. Exeter sits about level with that.

Carbon monoxide

Any appliance that burns fuel can produce carbon monoxide when combustion or venting goes wrong, and CPSC describes low to moderate poisoning as producing symptoms "similar to the flu (but without the fever)". Flu without a fever, in winter, in a house with the heating on — which is why it is missed.

Hot water or steam

Steam and hot water are two machines wearing one word. One runs at a few pounds of vapor pressure and depends on pitch and venting; the other runs as a pumped loop and depends on pressure and air removal. Say which you have when you call and the conversation starts a step further along.

What to ask whoever comes

Ask what the pressure on the gauge should read for this system and what it reads now. On a hot water boiler those two numbers explain most of the complaints people call about, and almost nobody is told what the target is.

Checking a plumber in New Hampshire

The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.

A boiler is not a furnace, and the person you want knows the difference.Tell us it is a boiler, tell us what the gauge reads if you can see it, and we will route you to somebody in your area who works on them. You are never charged. Boilers apart, Exeter can use this number for anything.
