A water heater in Southampton is sized for a house that is empty in February and full in August, on whatever fuel reaches the street. We put Southampton homeowners in touch with one licensed, insured plumber who installs tank, tankless and heat-pump heaters in Town of Southampton, and we publish the 2026 prices and the rebate.
Water heaters in Southampton: what's different here
Gilded-age estates on the ocean lanes with the plumbing of several houses each, village Colonials and Capes on SCWA mains north of the highway, and bay-side houses in North Sea on wells and propane, in a Town whose population swells to almost 3.5 times its winter level.
Southampton has gas on some streets and propane and oil on the rest, and the heater that makes sense follows the fuel; the plumber we send you to asks what is at the meter before quoting.
About 49% of the Town’s 41,759 housing units were counted vacant at the 2010 Census, and the Town says its population swells to almost 3.5 times its winter level between Memorial Day and Labor Day, which is the August water-heater failure and the February frozen pipe in one figure. Southampton is the oldest and largest community of the summer colony, 69,036 Town residents at the 2020 Census; a Village rental now needs a 14-consecutive-day minimum (September 2025), and the Town’s minimum stay is 14 days, so a rented house is a house someone drains in November.
Permits in Southampton run through the Village of Southampton Building Department inside the village; Town of Southampton Building & Zoning Division for North Sea, Shinnecock Hills, Tuckahoe and the rest of the town; the plumber we put you in touch with handles the filing where one is required.

FAQ
Water heaters questions
Tank or tankless: which water heater for a Hamptons house?
A tank if the budget and the basement are ordinary: $800–2,500 installed for 40–50 gallons, labor $150–450 for a swap, 6–15 years of life by one guide and 8–12 by another. A tankless if the house fills up on Fridays and empties on Mondays: $2,638 average installed ($1,404–3,901), labor $600–1,900 because the venting and gas change, about 20 years of life, and no tank to fail in an empty house. A heat-pump water heater if the basement is big and warm: $1,200–3,500 installed and PSEG Long Island rebates up to $1,200 on an ENERGY STAR model in 2026, the only water-heater rebate left after the federal credit ended in 2025. On a propane or oil house, which is most of the fork, the fuel at the street decides more than the brochure does.
Do I need a permit to replace a water heater or boiler in East Hampton?
Ask the building department, because it does not say online. The Town of East Hampton’s Building Department publishes its permit requirements — two sets of quarter-inch plans, licensed-contractor documentation, notarized signatures, workers’ compensation, a survey — and a 13-question FAQ that never mentions plumbing, water heaters, boilers or gas piping; its fees rose in May 2024 and its desk ran 16–20 weeks behind in 2026. The Village of East Hampton issues in two to four weeks. The general pattern for like-for-like equipment swaps that touch no structure or service is a lighter permit, but no Town page states it, so we do not. The code applies either way: a temperature-and-pressure relief valve set no higher than 210°F and 150 psi, and an expansion tank on a closed system. The plumber we send you to files what the department asks.
