Pool Heater Installation & Replacement in Sag Harbor, NY
A pool heater in Sag Harbor costs about $2,799–4,849 for a 250,000–400,000 BTU gas unit plus $500–2,000 to install, or $2,500–7,500 all-in for a heat pump (national 2026), with gas running $150–400+ a month and a heat pump $50–300. Near the water, specify a cupro-nickel heat exchanger. We put Sag Harbor pool owners in touch with one licensed, insured pool company that sizes the heater for the pool and puts the pad where the town’s setback and noise rules allow.

A pool heater in Sag Harbor is the difference between a pool that is used in May and September and one that is used in August, and it is the most expensive thing on the equipment pad. We put Sag Harbor pool owners in touch with one licensed, insured pool company that installs heaters every spring, and we publish the 2026 ranges and running costs so the quote reads plainly.
Heaters in Sag Harbor: what's different here
Dense, steep village lots with 18th- and 19th-century houses and small pools squeezed into rear yards above a high water table, plus newer houses with larger pools on the moraine out toward Noyac and the bay.
In Sag Harbor the equipment pad is close to the neighbors and the water table is high, so the heater question is as much about the enclosure and the noise as the BTUs: Sag Harbor Village requires pool equipment in a closed, noise-screened structure. A heat pump is quieter than a gas heater running flat out, and the damp, salty air still argues for cupro-nickel.
The village historic district covers most of the old village; a pool fence, terrace or equipment enclosure visible from a street or neighbor needs a Certificate of Appropriateness before the building permit. Village construction hours are Monday–Friday 8am–7pm and Saturday 9am–5pm, with Sundays and holidays prohibited.
Permits in Sag Harbor run through the Village of Sag Harbor Building Department; Chapter 244 of the village code governs pools (15-foot setback, test hole above the seasonal high groundwater table, cartridge filtration, noise-screened equipment), and in the historic district a Certificate of Appropriateness comes first for visible exterior changes; the pool specialist we put you in touch with handles the filing where one is required.

FAQ
Heaters questions
Should I convert my Hamptons pool to salt?
Probably, if you own the pool for the long run and fix the corrosion details. A conversion costs $500–3,500 (about $1,000 typical: a $600–2,000 generator plus $100–500 to install; no draining if the water is balanced). Ongoing chemicals drop to under $100 a year against $175–800 for chlorine, the water is softer, and there is no chlorine to store. The recurring cost is the cell: $200–1,800 depending on which of four sources you believe, every 3–6 years, roughly $200–360 a year. The catch is corrosion: copper heat exchangers, soft limestone or natural-cleft coping, and steel hardware near the water. On the South Fork that means a cupro-nickel heater exchanger and sealed bluestone or porcelain coping, and near the ocean the salt was already in the air anyway.
How does Georgica Pool Co. work, and what does it cost me?
It costs homeowners nothing. You tell us about the pool once, roughly sixty seconds: where it is, what kind it is if you know, what it needs, and when. We put you in touch with one licensed, insured pool company that works your town and does that kind of work, service company or builder as the job requires, and they call you within one business day to look at it and quote it directly. We are a Hamptons-only referral service, not a pool company, and we are named for the pond, not connected to any business or property that shares the name: one company, and nobody else gets your number. Participating companies pay us a referral fee.
