Pool Heater Installation Long Island
Gas heaters, heat pumps, and hybrid systems sized and installed for your pool. Swim from April through October instead of just July and August. Serving Nassau and Suffolk County for over 25 years.
Swim Four Extra Months Every Year
Without a heater, most Long Island pools are comfortable from late June through early September. That is about 10 weeks. With the right heater sized for your pool, you swim from mid-April through late October. That is 28 weeks. Nearly three times the season for the same pool sitting in the same backyard.
We install gas heaters from Raypak and Hayward and heat pumps from AquaCal and Hayward. Every installation starts with a pool volume calculation and an honest conversation about how you actually use your pool. Weekend swimmer? Gas heater. Daily laps? Heat pump. We match the system to your habits, not the other way around.
Our crew handles the full installation. Gas line connection, electrical hookup, plumbing integration, venting, and code compliance. When we leave, the heater is running and the water is warming up.
Gas Heaters vs Heat Pumps
Two systems, two different strengths. Here is how they compare for Long Island pools.
Gas Heaters
Fast heat, any weather
- ✓ Heats pool from cold to 82°F in a few hours
- ✓ Works in any temperature, any weather
- ✓ 250,000 to 400,000 BTU for residential pools
- ✓ Best for weekend swimmers and on-demand use
- ✓ Lower upfront cost, higher monthly gas bills
- ✓ Extends season April through October
- ✓ Brands: Raypak, Hayward, Pentair
Heat Pumps
Low cost, daily efficiency
- ✓ Heats pool gradually over 24 to 48 hours
- ✓ Runs on electricity, 500% to 600% efficient
- ✓ Monthly operating cost a fraction of gas
- ✓ Best for daily swimmers who maintain temp
- ✓ Higher upfront cost, much lower monthly bills
- ✓ Best performance May through September
- ✓ Brands: AquaCal, Hayward, Pentair
Hybrid Setup
Best of both systems
- ✓ Gas heater for spring and fall shoulder seasons
- ✓ Heat pump for efficient daily summer heating
- ✓ Longest possible swim season on Long Island
- ✓ Lower monthly costs than gas-only operation
- ✓ Faster recovery than heat pump-only setup
- ✓ Best for families who swim often year-round
- ✓ We size and plumb both systems together
Why Sizing Matters More Than Brand
An undersized heater runs constantly and never gets the pool warm enough. An oversized heater wastes money upfront and cycles on and off too frequently, which shortens its lifespan. Getting the size right is the single biggest factor in whether you are happy with your heater five years from now.
We calculate your pool volume, factor in surface area and sun exposure, and determine the BTU output or heat pump tonnage your pool actually needs. For gas heaters, we also check your gas line capacity. An undersized gas line cannot deliver enough fuel to run the heater at full output. If the line needs upgrading, we coordinate that before the heater goes in.
We also evaluate your equipment pad layout. The heater needs proper clearance from walls, fences, and other equipment for ventilation and code compliance. If your current pad is tight, we plan the layout before installation day so there are no surprises.
Why Long Island Homeowners Choose Majestic for Heater Installation
25+ Years Installing Heaters
Raypak, Hayward, Pentair, AquaCal. We have installed every major brand across hundreds of Long Island pools. We know which models hold up, which ones have parts availability issues, and which ones fit specific equipment pad layouts.
Full Installation, Not Just a Drop-Off
We handle gas line connection, electrical work, plumbing integration, venting, and code compliance. When we leave, the heater is running, tested, and warming the water. Not sitting on your pad waiting for three other contractors.
We Service What We Install
If your heater needs repair down the road, you call the same company that installed it. Our techs already know your system, your plumbing layout, and your equipment history. No starting over with a stranger.
Raypak, Hayward, Pentair, and AquaCal
Those are the four brands we install and recommend. They are the same brands we see holding up 10 to 15 years on Long Island equipment pads. Parts are available, our techs know every model inside and out, and the warranty support is solid.
We do not push the most expensive unit on the shelf. We match the heater to your pool size, your swimming habits, and your budget. A 266,000 BTU Raypak gas heater is the right call for most residential pools on Long Island. If you need more output for a larger pool or an attached spa, we size up accordingly. No guessing.
Your Heater Lasts Longer With Proper Maintenance
Pool heaters on Long Island take a beating from salt air, humidity, and six months of sitting idle over winter. Corrosion is the number one killer. A heater that gets properly winterized during closing and inspected during pool opening lasts years longer than one that gets ignored.
Our weekly maintenance techs check heater operation on every visit. They catch ignitor issues, pressure switch problems, and error codes before they turn into full failures. That is the difference between a $150 part swap and a $2,500 replacement.
