Hanson · Boilers
Cold radiators, a leaking boiler, or an oil tank that's seen better days in Hanson? Learn the local permit steps and get connected with an independent boiler contractor who serves Hanson.
Hanson, Massachusetts
Roughly one in five Hanson housing units was built in 1939 or earlier, according to Census estimates, and houses of that era were typically built around a boiler feeding radiators. Add the fact that about a third of occupied homes in town burn fuel oil, and a Hanson boiler call can easily involve the burner and the tank as well as the boiler itself.
That oil connection is what sets Hanson boiler work apart. Replacing an oil burner, swapping an above-ground tank, or removing a buried one each appear on the Fire Department's permit schedule, separate from the gas and wiring inspections run through the Building Department.
We connect Hanson homeowners with independent heating contractors and don't service boilers ourselves. Call or send a request, and the contractor you're connected with will diagnose the system and explain your options.
Cold radiators on an upper floor often mean trapped air or low system pressure. If bleeding them doesn't help, a circulator or valve may be failing.
A drip from the relief valve can mean the pressure is running too high, while a leak from the boiler section itself is more serious and needs prompt attention.
Knocking in a hot water system can point to air, a failing expansion tank, or sediment. In a steam system, it often relates to water level or pipe pitch.
A burner that smells of oil or puffs smoke on startup needs a cleaning and combustion test, and possibly a nozzle or electrode repair.
Local knowledge
House age, oil heat, and the town's permit split matter most for boiler work in Hanson.
Prewar Housing
Census estimates count 19.9 percent of Hanson's 4,075 housing units as built in 1939 or earlier. Boilers in those houses may serve oversized radiators sized for drafty walls, which affects how a replacement should be sized.

Tank Work
The Hanson Fire Department's permit schedule lists above-ground oil tank installation or replacement and underground tank removal, with an on-site inspection for the latter. If a boiler conversion retires a buried tank, plan for that inspection.

Fire Prevention Role
Hanson's Fire Prevention Division handles oil burner and oil tank installation and removal as well as above- and underground propane tank work for homes. A propane boiler or a switch from oil to propane brings that office into the job.

Right now
Start with safety, then gather what the technician will ask about.
If a carbon monoxide alarm sounds or you smell gas, propane, or heavy oil fumes, move everyone outdoors and call 911 or your fuel company from there.
Most hot water boilers have a pressure and temperature gauge on the front. Note the reading so the technician knows whether the system is under- or over-pressurized; don't add water or adjust valves yourself.
Look at the tank gauge and when your last delivery was. Sludge stirred up by a low tank is a common cause of clogged filters and nozzles.
Know whether your oil tank sits in the basement, outdoors, or underground. That shapes the repair plan and any Fire Department permit if the tank has to be replaced.
What to expect
On an oil boiler, expect the burner to be cleaned, the nozzle and filter replaced as needed, and combustion tested with an analyzer. The technician should also check the circulator, expansion tank, relief valve, and low-water cutoff, and look at the chimney connection for blockage or corrosion.
When replacement is on the table in an older Hanson house, ask for sizing based on a heat loss calculation rather than the old boiler's nameplate. Many prewar boilers were sized generously, and a properly sized modern unit with outdoor reset control can run more steadily.
Permits follow the fuel: oil burner and oil tank work goes to the Fire Department, gas boilers involve the town's plumbing and gas inspector, and new electrical circuits go through the Building Department at Town Hall. The contractor should handle the filings and schedule the inspections.
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.
Oil burner technicians in Massachusetts hold a Department of Fire Services certificate; check it on the DFS verification site before work starts.
If your boiler burns gas or propane, confirm the gas fitter license through the state's occupational license search.
Older Hanson homes may have steam or gravity-era piping. Ask how many systems like yours the contractor has worked on.
If the boiler, burner, or fuel changes, the written estimate should cover what happens to the oil tank, who files the fire permit, and the inspection.
Costs
Repairs depend on the part and how old the boiler is; older units can need components that have to be ordered. Replacement cost turns on the boiler type and efficiency, venting or chimney liner changes, near-boiler piping, and whether the oil tank stays, gets replaced, or comes out.
A fuel change, from oil to gas or propane, or to a heat pump with the boiler as backup, adds permits and labor but may open Mass Save offers through your utility. Ask each contractor for a written estimate that separates boiler, burner, tank, venting, and permits so the bids line up.

Questions
Still not sure? Send a short request and a local pro can answer the specifics.
Yes. Oil burner installation or replacement is on the Hanson Fire Department's permit schedule. Your contractor should file it and arrange any inspection.
If it's being removed, Hanson Fire Department rules call for an on-site inspection of the underground tank removal. Ask the contractor who handles the removal and the permit.
Trapped air and low pressure are the usual causes in hot water systems, and water level or pipe pitch in steam systems. A technician can find out which and whether a part has failed.
It can be, depending on gas availability on your street, the boiler's age, and your comfort goals. Ask for written quotes on staying with oil, converting, and adding a heat pump so you can compare.
