Fast, Powerful Heating with Gas and Propane Pool Heaters
When you need to heat your pool quickly, especially in cooler weather, gas and propane pool heaters are the most effective solution. These high-performance systems deliver rapid temperature increases, making them ideal for both inground and above ground pools, and for pool owners who want on-demand heating without waiting hours or days.
Whether you're looking for a compact propane heater for a weekend swim or a high-BTU natural gas model for a large inground pool, Doheny’s carries a wide range of options to suit your needs.
Why Choose a Gas Pool Heater?
Gas pool heaters are known for their speed, reliability, and cold-weather performance. Unlike heat pumps or solar systems, gas heaters don’t rely on air temperature or sunlight—they generate heat by burning fuel, which means they work efficiently in any climate. Today’s advanced gas heaters are designed to minimize nitrogen oxide (NOx) emissions, helping reduce air pollution while still delivering powerful, consistent heating performance.
Key Benefits:
- Fast Heating: Raise water temperature by 1–3°F per hour
- All-Weather Performance: Works even in cold or cloudy conditions
- On-Demand Use: Perfect for occasional swimmers, weekend, or evening use
- Compact Options: Available for both above ground and inground pools
Natural Gas vs. Propane Pool Heaters
Both fuel types offer powerful heating, but there are some key differences:
| Feature | Natural Gas | Propane |
|---|---|---|
| Fuel Source | Requires a gas line | Uses refillable tanks |
| Installation | Permanent setup | More flexible placement |
| Best For | Homes with existing gas service | Homes with existing propane tanks or no access to natural gas |
If you already have a natural gas line, a gas heater is usually the most cost-effective choice. If not, propane offers flexibility and portability, especially for above ground or seasonal pools.
Choosing the Right Size Gas Heater
The size of your pool and your desired heating speed will determine the BTU rating you need. Here’s a general guide:
| Pool Volume | Recommended BTU |
|---|---|
| Up to 10,000 gallons | 100,000–150,000 BTU |
| 10,000–20,000 gallons | 150,000–250,000 BTU |
| 20,000–30,000 gallons | 250,000–350,000 BTU |
| 30,000+ gallons | 350,000–400,000+ BTU |
Tip: If you want faster heating or live in a colder climate, consider sizing up.
Installation & Safety Considerations
Gas and propane heaters are powerful appliances and should be installed with care. Here are a few things to keep in mind:
- Ventilation: Ensure proper airflow and clearance around the unit
- Fuel Access: Natural gas line, electrical line, or propane tank must be safely connected
- Maintenance: Regular maintenance, including inspection of burners and heat exchangers, is essential to ensure optimal performance and extend the heater's lifespan.
Frequently Asked Questions
How fast can a gas pool heater warm my pool?
Gas heaters can raise water temperature by 1–3°F per hour, depending on pool size and heater capacity.
Can I install a gas pool heater myself?
Gas and propane heaters are powerful appliances and should be installed with care. While it is easier to replace an already-existing gas heater, connections to the gas and electrical lines still need to be thoroughly checked by a gas company. Professional installation is recommended for new systems.
Are gas pool heaters energy-efficient?
Modern gas heaters are more efficient than older models. Look for units labeled with 'low NOx emissions' for improved energy efficiency for better performance and reduced environmental impact.
