Water Heater Installation, Replacement & Repair in Northborough, MA
A cold shower in Northborough isn't just unpleasant — it's a sign your water heater needs attention. Richard T. Curley Plumbing & Heating handles everything from pilot-light fixes to full tank installations and replacements in Northborough homes. Whether yours is gas, electric, or tied to an oil boiler, we diagnose the issue and get your hot water back the same day.
Northborough is a gas town first, but it's a gas town with a second chapter. Eversource runs down Route 20 and through the older colonials, so most of the basements we open hold a gas-fired tank or a newer power-vent unit. But Northborough has a real block of older homes that still heat with oil boilers — and those usually carry an indirect water heater, a separate tank piggybacked on the boiler. That's more common here than in a lot of the towns around us, which means Northborough water-heater calls are a real mix: gas tanks, power-vent conversions, electric in the newer townhomes and heat-pump houses, and indirect tanks off oil boilers. We've been sorting through all of it since 1980.
There’s no hidden utility bargain buried here — Northborough sits on standard investor rates, not a municipal utility. That keeps the math simple: gas is the economical lead for most of this town, and an indirect tank makes sense where the boiler still has life left in it. The honest advice we give is the same now as forty years ago: match the fuel to the house, not the other way around.

"Specializing in water heaters"
“Specializing in Water Heaters” We don’t just say that — it’s written right on the side of our trucks, and it has been for over 40 years.
In Northborough’s older colonials, we mostly find atmospheric-vented gas heaters in basement corners near the chimney, close to where the old boiler sat — and in the newer townhomes, no chimney at all.
Gas Water Heaters
Gas water heaters (natural gas or propane) are atmospheric-vented models, venting galvanized pipe into a chimney. When a home converts its heat to mini-splits, the water heater gets left alone in an oversized chimney and the draft goes bad — which is exactly when a power-vent upgrade becomes the fix.
We see the same fit issues in Northborough’s older colonials — a modern tank is wider and taller than the same-gallon unit it replaces, so in a low-ceiling basement we’re often reaching for a lowboy or rethinking the location.

Indirect Water Heaters
Indirect Water Heaters In Northborough’s older homes that still heat with an oil boiler, the water heater is often an indirect tank — a separate storage tank that borrows its heat from the boiler itself. We service and replace those too, and the real question is usually the boiler behind it: if the boiler still has years left, a fresh indirect tank is the economical move; if the boiler is on its last legs, that’s a different conversation.

Power-Vent Water Heaters
Power-vent water heaters are the atmospheric model with a re-engineered exhaust — a PVC vent and a blower on top that pushes combustion by-products out the roof or a sidewall when there’s no reliable chimney. They’re the right answer when a Northborough home has gone away from the old boiler stack, but the trade-off is the foundation: routing a PVC vent through a thick, older foundation wall is work you want done right the first time.
That said, sizing is the part people skip. The spec-sheet gallons per minute assumes warm incoming water, and when Northborough’s water is near 40°F in January a unit rated 9 GPM realistically delivers closer to 4 — so sizing for winter, not the brochure, is the whole job.

Electric Water Heaters
Electric water heaters and especially the hybrid heat-pump models — are the quiet second story in Northborough, showing up in the newer townhomes, condos, and heat-pump houses where there’s no gas line. The catch is the space: a heat-pump unit stands taller and wider than a standard tank and needs plenty of surrounding air to pull heat from, and a tight Northborough basement often doesn’t have it. In those homes it’s a standard electric, sized to the stairs it has to come down.
And in the newer townhome communities, the tank usually lives in a closet with no floor drain — so a leak pan and auto-shutoff aren’t extras, they’re how a swap gets done right in that space.

Yes. Most Northborough basements have a gas tank near the chimney, but a lot of the older homes run an indirect tank off an oil boiler, and the newer townhomes run electric. A quick description or a photo you text us usually tells us what we’re walking into, and we’ll bring the right parts on the first trip.
In most cases, yes — an indirect tank that piggybacks on the boiler. We service and replace the boiler and the tank together, and if the boiler still has years in it, a fresh indirect tank is often the cheapest way to get reliable hot water.
It depends on fuel type, tank size, and access. A standard gas tank in an open basement is the most straightforward; an indirect tank off an oil boiler or a power-vent with a long PVC run costs more. We give you a clear number before we start, not a surprise after.
Most tanks last 10 to 15 years with care, though sediment and hard water can shorten that. If yours is pushing that age and acting up, we’ll tell you honestly whether it’s worth a repair or time for a replacement.
