Do not.
Every year someone asks about a used boiler — cheap on marketplace, "only 10 years old." The answer is no, for three reasons: 1) no warranty, 2) unknown history (was it weeping? overheated? frozen?), 3) installation costs the same as new, so the "savings" evaporate while the risk stays.
The only exception: a known unit from a known source (your own building's phased replacement). Everything else is someone else's problem, purchased at full installation price.
First, always.
Before any replacement talk, the existing boiler gets an honest assessment: is the block sound? A sound block with a tired burner is a burner rebuild — often a tenth of replacement cost. A weeping block ends the debate. Too many workhorse boilers get replaced for burner problems.
When replacement is right — weeping block, efficiency so low the fuel pays for the job, or parts obsolete — the fuel question follows.
The honest math.
Price both : modern oil (no conversion cost, annual service) vs. gas (service line, venting, chimney work).
Either way, demand: heat-loss sizing (not the nameplate), near-boiler repiping, outdoor reset, and startup tuning verified with instruments. See our national installation guide.
Five questions.
Not the nameplate.
Taunton’s legacy boilers were sized for leakier envelopes and colder assumptions — many run two to three times the house’s actual load. An oversized boiler short-cycles: fires hard, satisfies the thermostat in minutes, shuts down, repeats — wasting fuel, wearing components, and heating unevenly. Proper sizing is a heat-loss calculation: room by room, windows, insulation, air leakage, design temperature — not the old nameplate, not a rule of thumb per square foot. The right-sized unit runs longer, steadier cycles. Ask any installer “how did you size it” and listen for the calculation; “same size as the old one” is the wrong answer wearing confidence.
Lab numbers vs. realized savings.
Modern oil and gas boilers publish AFUE in the mid-80s to low-90s, versus 60s–70s for a 35-year-old workhorse — but AFUE is a lab number. Realized efficiency depends on sizing (see above), near-boiler repiping, outdoor reset control, and annual service keeping combustion tuned. A right-sized modern unit with outdoor reset, verified by combustion instruments at startup, is where the fuel savings actually live.

Straight answers before you call.
When repairs come every winter on a 30-plus-year-old unit, replacement usually wins the math — each breakdown risks a no-heat stretch in January, and a right-sized new boiler burns noticeably less fuel. The honest test is the pattern: isolated fault means repair; recurring failures across the system mean replace. Bring the last two winters' history to the call.
Whatever a heat-loss calculation says — most Taunton systems were sized by rule of thumb decades ago and are oversized, which wastes fuel and short-cycles equipment to an early grave. Square footage alone is not enough; insulation, windows, and air leakage all count. Any replacement quote that skips the heat-loss math is a quote to decline.
It depends on your street — gas mains serve much of Taunton but not every block — then the chimney, the piping, and the abandoned oil tank. The gas-or-oil math is done once and lived with for decades, so it deserves a real conversation.
Almost always yes — radiators outlast several boilers, and new units are routinely piped to existing radiator systems. The efficiency gains live in the near-boiler piping and the controls. Tell the tech how many floors and radiators the system feeds so the sizing reflects the real load.
Less than most owners fear — the old unit comes out and the new one goes in over a compact window, with heat typically restored the same stretch, and the radiators usually stay. The planning (sizing, venting, fuel decision) takes longer than the wrench work. Ask about the schedule on the call so tenants get a straight answer.
