POOL HEATER INSTALLATION • Long Island, NY

Pool Heater Installation on Long Island

Empire Pools installs and replaces gas heaters and heat pumps across Suffolk and Nassau County. We size your new heater correctly, clean up the pad, and coordinate the details so you can start your season earlier and stay warm later without guessing which buttons to push.

What to Expect

Stay Warmer, Longer on Long Island

A properly-sized pool heater is more than just BTUs on a box. We look at your pool size, depth, wind exposure, cover usage, and how you actually swim before recommending a heater. Our team explains gas heaters vs. heat pumps, reviews your existing gas and electric setup, and helps you choose a model that fits your budget and goals. On install day we set the heater on a solid base, re-plumb the pad with unions and bypass where appropriate, and work with your licensed gas and/or electrician to finish connections. Once everything is live, we bleed air, fire the heater, verify flow and temperature rise, and show you exactly how to use and protect your new heater through the season.

What’s Included

  • On-site review of pool size, pad layout, wind exposure, and cover use.
  • Discussion of gas heater vs. heat pump options and which makes sense for your property.
  • Heater sizing recommendations based on pool volume, target temperature, and season length.
  • Removal of old heater (if applicable) and preparation of a stable pad or base for the new unit.
  • Clean, service-friendly plumbing with unions, shutoffs, and bypass where appropriate.
  • Integration with your existing pump, filter, and, where applicable, automation or salt system.
  • Startup and testing: purge air, verify proper flow, and confirm heater is firing and holding temp.
  • Owner walk-through at the pad — modes, setpoints, basic troubleshooting, and protection tips.
  • Labeling of key valves and controls so you’re not guessing after we leave.
  • Note: Gas line and electrical work are handled by a licensed professional. We can coordinate with your contractor or recommend options. Pool heater installation is custom — call for pricing.

Pool Heater Installation — FAQs

What size heater do I need for my pool?
Sizing depends on pool volume, exposure, cover usage, and how quickly you want to heat. Bigger is not always better — oversizing can waste gas without much benefit. We’ll calculate the right BTU range for your pool and review options in that bracket so you understand heat time vs. operating cost.
Should I choose a gas heater or a heat pump?
Gas heaters usually heat faster and are great for spas or occasional use. Heat pumps are more efficient in the right temperatures but take longer to bring the pool up. We’ll look at how you use the pool, local utility rates, and your yard to recommend the best fit — in some cases a hybrid approach makes sense.
Do you handle gas and electrical connections?
Gas and electrical work are completed by a licensed professional. We can coordinate with your gas/electric contractor or connect you with options. Our team handles the pool-side plumbing, pad layout, and heater setup so everything mates up cleanly when the licensed trades finish their part.
How long will it take to heat my pool?
Heat time depends on the heater size, starting water temp, air temp, wind, and use of a cover. As a rough guideline, many properly-sized heaters can raise temperature a few degrees per hour under normal conditions. We’ll set realistic expectations for your specific pool when we size and quote the job.
Do I really need a cover if I have a heater?
Yes — using a cover dramatically reduces heat loss and operating costs, especially at night and on windy days. A heater without a cover is constantly fighting evaporation. We’ll review cover options and simple habits that protect your new heater investment and keep bills under control.
