Stoughton · Boilers
Lost both heat and hot water in your Stoughton home? Your boiler may make both. Learn what that means for the repair, then call or send a request to reach an independent local heating contractor.
Stoughton, Massachusetts
In many Stoughton homes, the boiler isn't only the heating system. It also heats the water for showers and sinks, either through a coil built into the boiler or through a separate indirect tank piped to it. That's why a boiler failure here can mean a cold house and a cold shower on the same morning, and why a replacement has to plan for both.
The town's housing spans a wide range. About 17 percent of homes were built in 1939 or earlier, close to 2,000 units, and many of those older basements hold cast-iron boilers serving steam or hot water radiators. Newer houses more often have hot water baseboard. Gas from Eversource heats about 58 percent of occupied homes, and oil about 24 percent.
Below are the signs to watch, what a contractor will check, and the questions that keep hot water from being an afterthought. When you call or send a request, you'll be connected with an independent heating contractor who works in Stoughton.
With a coil boiler, hot water that turns lukewarm halfway through a shower often means scale has built up on the coil or the boiler's temperature control is off.
Scalding water from a boiler coil can mean a failed mixing valve. That's a burn risk, especially for children and older adults.
A coil boiler stays hot year-round to make hot water. If yours seems to run constantly in warm months, ask whether an indirect tank or a separate water heater makes sense.
Water around an indirect tank, or rust at its base, can mean the tank is failing even though the boiler itself is fine.
Local knowledge
The age of the housing, the fuel mix, and the permit offices all affect what a boiler job involves.
Prewar Homes
A 2026 regional housing assessment counts about 1,955 Stoughton housing units built in 1939 or earlier. Boilers in these homes may still serve original radiators, and some still make hot water through an internal coil.

Oil And Gas
Census estimates show about 58 percent of occupied homes on utility gas and about 24 percent on oil. Coil-type boilers are common on oil systems, and they lose hot water as soon as the burner stops.
Fire Permits
The Stoughton Fire Department issues residential oil burner permits, propane permits, tank install plan reviews, and tank removal permits. An oil boiler replacement goes through this office.

Gas Inspections
Stoughton's Gas and Plumbing Inspector works through the Building Department, and all inspections are scheduled through its administrative staff. A gas boiler swap is inspected this way.
Right now
Make sure the house is safe before anything else.
Should you smell gas or hear a CO alarm, everyone goes outside now, pets included, and nobody stops to investigate. Make the call to 911 or the Eversource gas emergency line from the yard or a neighbor's house.
Read the tank gauge. An empty tank stops both heat and hot water on a coil boiler, and the line may need bleeding after a delivery.
Run a hot tap and note whether hot water is gone too, or only heat. That tells the technician whether to look at the coil, the tank, or the heating side.
Don't adjust valves on the boiler or tank. Mixing valves and relief valves can release scalding water.
What to expect
A technician will typically test combustion and venting, check the circulators, expansion tank, and relief valve, and look at how hot water is produced. On a coil boiler that means the coil, the mixing valve, and the boiler's temperature settings. With an indirect tank, expect checks of its zone valve or pump, its thermostat, and the tank itself.
For replacement, oil work goes through the Fire Department's oil burner permit and gas work through the Building Department, which schedules inspections through its office staff. If a coil boiler is being replaced, ask whether the new setup will use an indirect tank, a combination boiler, or a separate water heater.
An older Stoughton basement may be cramped or have low beams. Mention access when you call, since a boiler and tank swap may involve moving two large appliances.
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.
Verify a gas fitter license through the state's occupational license check for gas boilers. For oil, confirm the oil burner certificate on the Department of Fire Services site.
Ask each contractor to describe exactly how the new system produces hot water, and how much it can supply at once.
In a prewar Stoughton house with steam radiators, ask how often the contractor works on steam and how they'd size a new boiler.
Make sure the boiler, hot water equipment, venting, piping, old unit removal, and permits are all listed.
Costs
Hot water is a key variable. Replacing a coil boiler with another coil boiler is a different scope from adding an indirect tank or moving to a combination boiler, and each changes the piping and controls. Steam systems, venting changes, and tight access add time.
Ask each contractor to quote the same heat and hot water setup so you can compare. Eversource and National Grid sponsor Mass Save, so check the current offers on boilers, water heating, and heat pumps before choosing.

Your boiler probably makes both, through an internal coil or an indirect tank. When the boiler stops, so does the hot water. A technician can tell whether the problem is the burner, the controls, or the fuel supply.
Many homeowners do, because an indirect tank stores hot water and lets the boiler rest between calls. It takes space and piping, so ask the contractor to compare it with a coil or combination boiler.
The Stoughton Fire Department issues residential oil burner permits and tank permits. Gas boiler work goes through the Building Department. Your contractor normally files the right one.
Yes. It often means the mixing valve that tempers coil water has failed. Use caution at the taps and have the valve checked soon.
