Pool Heaters Long Island
Gas heaters and heat pumps from trusted brands, sized right for your pool and installed by a team that has been doing this on Long Island for over 25 years.
The Right Pool Heater Makes All the Difference
Most Long Island pools sit unused from mid-September through May. That is roughly eight months where your backyard investment does nothing. A properly sized pool heater changes that math completely.
We install and service gas heaters and heat pumps from Pentair and Raypak across Nassau and Suffolk County. Every unit we sell gets matched to your pool size, your usage habits, and how early in the spring you want to start swimming. There is no guessing involved.
Homeowners in Bay Shore, West Islip, Babylon, and Deer Park already know what a difference the right heater makes. Open in April. Swim through October. That is a full seven months instead of three.
Pool Heater Brands We Carry
We work with two manufacturers we trust. Both have proven track records in Long Island weather conditions and both carry parts availability that keeps your heater running for years.
Pentair Max-E-Therm
The Max-E-Therm is one of the most popular gas pool heaters on Long Island for good reason. It fires up fast, heats water quickly, and runs quietly. Available in 200K, 333K, and 400K BTU models so we can match the right size to your pool volume. Low-NOx emissions meet current air quality standards, and the compact design fits into tight equipment pads that are common on Suffolk County properties.
Raypak Heaters & Heat Pumps
Raypak builds gas heaters and heat pumps designed for real-world conditions. Their gas units handle wind, rain, and cold starts without the issues cheaper models have. The heat pump line comes standard with titanium heat exchangers that resist corrosion from salt systems and chemically treated water. If you run a saltwater chlorine generator, that titanium exchanger matters.
Getting the Right Size Heater for Your Pool
An undersized heater runs constantly and never gets the water warm enough. An oversized unit wastes money upfront and cycles on and off too frequently, which shortens its life. Getting the size right is the single most important decision in the whole process.
When we come out to look at your setup, we measure your pool volume and factor in everything that affects heat loss on your specific property.
- Total pool volume and surface area
- How many degrees you want the water raised above ambient temperature
- Wind exposure on your property
- Whether you use a solar cover or safety cover
- Shade from trees, fences, or structures around the pool
- Your gas line size and supply capacity
We have been sizing heaters for Long Island pools for 25 years. Homes along the Great South Bay in Lindenhurst and Copiague get more wind exposure than a fenced-in yard in North Babylon or Brentwood. That stuff matters and it changes the recommendation.
Choosing the Right Heater Type
There are two main types of pool heaters we install on Long Island. Each one works differently and fits different situations.
Gas Pool Heaters
Gas heaters burn natural gas or propane to heat water fast. They work in any weather, any temperature, and raise your pool 20 to 30 degrees in a matter of hours. Best for homeowners who heat on demand or want to swim early spring and late fall when air temps are still in the 50s and 60s. Most Long Island homes already have natural gas, which keeps operating costs reasonable.
Heat Pump Pool Heaters
Heat pumps pull warmth from the outside air and transfer it into the water. They cost less to run than gas heaters month over month. The tradeoff is speed. They heat gradually, so they work best when you run them consistently through the season rather than turning them on the night before a pool party. Once air temps stay above 50°F, a heat pump keeps your pool comfortable at a fraction of the gas cost.
Which One Is Right for You?
If you swim every weekend from May through September, a heat pump will save you money over the season. If you heat the pool a few times a month or want to push into October and November, gas is the better call. Some homeowners run both. We will tell you what makes sense for your pool and your budget when we come out to look at the setup.
Why Long Island Homeowners Buy Heaters From Us
25+ Years on Long Island
We have been installing pool heaters in Nassau and Suffolk County since before most of the companies you see online existed. We know Long Island pools because we work on them every day.
We Size It Right
Every heater we sell gets sized on-site for your pool. We measure your volume, check your gas line, and account for wind and shade. No guessing. No call-center recommendations based on a form you filled out online.
Installation and Service
We do not just sell you a heater and leave. We install it, test it, and come back to service it when you need pool heater installation or repairs. One company for the whole relationship.
How Long Pool Heaters Last on Long Island
A gas pool heater typically lasts 8 to 12 years on Long Island. Heat pumps often go 10 to 15 years with proper maintenance. The salt air in coastal areas like Amityville, Copiague, and Lindenhurst can shorten that if the unit is not built with corrosion-resistant materials.
That is one reason we carry Raypak heat pumps with titanium exchangers. Titanium does not corrode the way copper-nickel does in salt-heavy environments. For homeowners running saltwater pool systems, that is a real difference in equipment life.
Keeping Your Heater Running Right
Pool heaters need regular attention to perform well. We check heater operation during our weekly pool maintenance visits and flag problems before they become expensive repairs.
Common maintenance items include cleaning the burner tray and orifices on gas units, checking ignition systems, verifying thermostat calibration, and clearing debris from heat pump coils. A heater that gets serviced annually runs more efficiently and lasts longer than one that gets ignored until it stops working.
If your current heater is struggling to keep up, making strange noises, or shutting off mid-cycle, call us. We handle pool repair for all the brands we sell and most of the ones we do not.
