Scituate · Boilers
Cold radiators, a leaking boiler, or a prewar Scituate house that needs a new heating plant? Learn what to check and how to reach an independent boiler contractor who serves Scituate.
Scituate, Massachusetts
Scituate has a deep stock of old houses. The town's 2025 Housing Production Plan counts 2,121 housing units built in 1939 or earlier, a quarter of the total, and homes from that era were commonly heated by steam or hot water radiators. Many still are, which means a lot of Scituate heating calls involve near-silent circulators, sputtering air vents, and sight glasses rather than ductwork.
Boilers in these houses have often been replaced once or twice while the original piping stayed. That mix of new boiler and century-old radiators can work well, but it also explains a lot of the cold-radiator, banging-pipe, and pressure-relief complaints contractors hear.
To get help, call or send a request. You'll be connected with an independent heating contractor who works on boilers in Scituate, and you choose whether to hire them.
Trapped air, a stuck vent, or a failing zone valve or circulator often leaves part of the house behind.
A relief valve that keeps discharging points to high pressure, an expansion tank problem, or a leaking fill valve.
Water trapped in sagging steam lines can hammer loudly; a technician can find where the piping lost its pitch.
Leaks at the base of a cast-iron boiler can mean a cracked section, which usually means replacement.
Local knowledge
House age, flood exposure, and a recent water notice all bear on Scituate boilers.
Prewar Housing
That figure, from the 2025 Housing Production Plan, is about a quarter of all housing units in town. Original radiators and large-diameter piping in these houses set the limits for any new boiler, especially when converting from steam to hot water.

Basement Flood Risk
Boilers usually sit on the basement floor, exactly where storm surge and heavy rain collect. If you're in a flood zone, ask about raising the boiler on a platform, relocating it, or choosing a wall-hung unit when it's time to replace.

Boil-Water Order 2026
Following E. coli detections on October 27, 2026, MassDEP issued a boil-water order that was lifted on November 1, 2026, and the town advised changing water filters and flushing household lines. If your boiler also heats tap water through an indirect tank or a coil, ask a contractor how to flush that part of the system.

Right now
Put safety first, then gather details that help the technician.
If you notice a gas odor, smell exhaust, or a carbon monoxide alarm sounds, get everyone out and call 911 from outside before doing anything else.
Note the pressure and temperature on a hot water boiler, or the water level in a steam boiler's sight glass, and tell the contractor what you see.
If flood water reached the boiler or its controls, switch it off at the emergency switch from a dry spot only, and leave it off for a professional.
Note which radiators or zones are cold, any noises, and whether the trouble started after a storm or a power outage.
What to expect
A service visit typically includes a combustion check, inspection of the flue and chimney connection, a look at the expansion tank and relief valve, and on steam systems, the low-water cutoff and main vents. In older Scituate houses, the technician may also trace the piping to see where air or water is getting trapped.
If replacement comes up, expect a measurement of every radiator so the new boiler can be matched to the house's real heat load. Converting steam to hot water, or adding an indirect water heater, are bigger projects and should be explained in writing.
A new gas boiler needs a permit from Scituate's Building/Inspections Department, filed through its online-only system, and wiring changes can add an electrical permit. The contractor typically files and arranges the inspection through the town's portal.
Hire smart
Massachusetts has no single HVAC license. Gas work needs a gas fitter license, oil burner work a Department of Fire Services certificate, ductwork a sheet metal license, and larger refrigeration systems a refrigeration technician license. Most heating and cooling installs need a town permit.
Steam systems behave differently from hot water. Ask how many steam boilers the contractor has worked on and how they handle near-boiler piping.
Gas boiler work needs a gas fitter license you can check on the state's occupational lookup; oil boiler work needs a Department of Fire Services certificate.
In a flood-prone basement, ask whether the boiler and controls can be raised or moved, and what that adds to the job.
Ask to see how the size was calculated from your radiators and heat loss, not copied from the old nameplate.
Costs
Repairs depend on the part and the age of the system; circulators and vents are common, while sections and controls for old boilers can be harder to find. Replacement cost turns on boiler type, chimney or venting changes, near-boiler piping, raising the unit above flood level, and any switch between fuels.
Ask each contractor for a written estimate listing the boiler model, piping and venting work, permits, removal of the old unit, and any Mass Save offer for high-efficiency equipment through your gas or electric utility. Compare scope as well as the total, and ask what the estimate excludes.

Questions
Still not sure? Send a short request and a local pro can answer the specifics.
Air in the lines, stuck vents, a failing circulator or zone valve, or piping that has lost its pitch are common causes in older homes. A contractor can find which applies.
Often, yes, but it depends on the radiators and piping. A contractor should inspect the system, explain what has to change, and put the scope in writing.
The heating side of a boiler is a closed loop, but if the boiler also makes your hot water, the town's advice to flush household lines after the November 1, 2026 lift applies to that part. Ask a contractor how to do it safely.
If your basement has flooded or sits in a mapped flood zone, ask a contractor about a raised platform, relocation, or a wall-hung boiler at replacement time.
The Building/Inspections Department handles gas and electrical permits, and all applications are online. Your contractor normally files them and books the inspection.
