POOL HEATER INSTALLATION •
Pool Heater Installation in ,
Empire Pools installs and replaces gas pool heaters and heat pumps for homeowners who want a longer, more reliable
swim season. We don’t just “swap the box” — we help you choose the right heater based on pool size, target temperature,
cover usage, and real-world backyard conditions (wind exposure, shade patterns, and colder nights can change what “enough heat”
actually means). We also look at your equipment pad and plumbing so the finished install is clean, service-friendly,
and easy to operate — with unions, shutoffs, and a layout that makes sense.
Because installs often vary by property, we walk you through the practical details up front: gas vs. heat pump,
warm-up expectations, operating cost considerations, and what needs to be coordinated with a licensed gas and/or electrical pro.
Whether your pad is tucked behind the house near Route 25A, off Nesconset Highway (NY-347), close to Stony Brook Road,
around Old Field Road, or along residential streets near the Stony Brook University area, we plan the job around access,
airflow clearances, and a neat final setup. The goal is simple: start your season earlier, stay warm later, and never have to
guess which buttons to push.
What to Expect
Stay Warmer, Longer in
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.

Pool Heater Installation — FAQs
What info do you need to quote a heater install in East Setauket?
The fastest quote comes from photos of the equipment pad, your pool size (or rough dimensions),
whether you want gas or heat pump, and whether there’s gas and/or adequate electrical capacity available.
If you can, include a photo of any existing heater label and tell us your target water temp and months of use in .
How do you pick the right heater size for my pool?
We size for real conditions: pool volume, desired temperature rise, wind exposure, shade, and cover use.
Bigger heaters can warm faster, but cost more to run. We’ll recommend a BTU range (or heat pump tonnage) that matches your goals,
then explain what warm-up time looks like in typical spring/fall weather.
Gas heater vs. heat pump — which is better for Long Island?
Gas heaters usually heat faster and are great for weekend swims or attached spas. Heat pumps are typically more efficient
when air temps are warm enough, but they heat slower. The “better” choice depends on your swim habits, utility rates, and expectations.
We’ll tell you straight if a heat pump will feel too slow for how you use the pool.
Do you install bypass and unions on heater plumbing?
Yes whenever appropriate. A proper layout usually includes unions for service, shutoffs, and often a bypass so flow can be tuned
and the heater can be isolated if needed. This keeps your equipment pad in clean and service-friendly instead of “cut-and-replace.”
What’s a realistic warm-up time after a new heater install?
It depends on heater type and conditions. Gas heaters can often raise water temperature a few degrees per hour in normal conditions,
while heat pumps are slower but steady. Wind and uncovered nights can erase gains fast—so pairing the heater with a cover is usually the biggest
“cheat code” for faster heat and lower cost.
Can you coordinate with my gas plumber or electrician?
Yes. We handle the pool-side heater setup and plumbing, and we’ll coordinate timing so the licensed gas and/or electrical work connects cleanly.
If you don’t already have someone, we can point you toward local options.
What maintenance will my heater need?
For gas heaters: keep airflow clear, maintain proper water chemistry, and address scale early. For heat pumps: keep coils clear and ensure drainage.
We’ll show you the simple seasonal checks and how to protect the unit during closing so it lasts longer in .
