A water heater in Amagansett is sized for a house that is empty in February and full in August, on whatever fuel reaches the street.

Water heaters in Amagansett: what's different here

Estates on Further Lane and Bluff Road behind the double dunes with outdoor showers and pool houses in full salt air, shingled village houses on the Lanes, and houses in Stony Hill and the woods north of the highway on wells, oil and propane.

On the ocean side of Amagansett the water heater lives in salt air, which shortens a tank’s life and corrodes a tankless heat exchanger’s vent; plumbers who work the beachfront in Amagansett spec the venting for it and the outdoor shower for a winter shutoff.

Amagansett is a hamlet of the Town of East Hampton, permitted through the Town’s Building Department with its two sets of plans, licensed-contractor documentation and survey, on a desk that ran 16–20 weeks behind in 2026; 1,824 people lived here at the 2020 Census. South of the highway, the Lanes, Bluff Road and Napeague take full ocean exposure — salt spray on the outdoor plumbing and the equipment pads, blown sand in everything — and north of the highway Stony Hill and the woods are moraine till on wells, where the pressure tank and the pump control box are the winter’s weak points.

Permits in Amagansett run through the Town of East Hampton Building Department; 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.
