How we picked
This guide covers 15 propane pool heaters from a pool of 23 listings, all with titles that state propane or LP as the fuel type. The products are compared on the details stated in each listing title, including BTU output, pool type (inground or not stated), voltage, and any additional features like digital control or millivolt ignition. The ordering rule ranks picks by the number of stated details (type, btu, kw, pool, pool_gallons, voltage, inverter, wifi), then by stated BTU from largest to smallest, then by the order in the pool file. No product is ranked by price, popularity, or value. The guide includes at most 5 picks from any one brand, with Raypak holding most listings, to ensure a spread of options.
How to choose
Propane or LP: what the title names
Every pick in this guide has a title that states propane or LP as the fuel type. Propane gas heaters burn propane stored in a tank, which is a common choice for pools without a natural gas line. The title naming propane is the only evidence this guide uses; the heater's compatibility with your existing propane supply is something to confirm with the maker's manual and a licensed gas installer.
BTU figures and what they leave out
The BTU figure in a title states the heating output of the heater. Higher BTU numbers generally indicate a larger heating capacity, but this guide never matches a BTU figure to a pool size or a heating time. The title may state a BTU figure, but it does not say how quickly the heater warms a pool or what pool size it suits. Read the maker's sizing page and manual, and ask a licensed installer for advice on the right output for your pool.
Inground or above ground: what the title names
Some titles in this guide state the heater is for inground pools, while others do not name a pool type. A title that names inground pools is the only evidence this guide uses; it does not imply the heater cannot be used above ground. If a title does not state a pool type, the guide writes 'not stated by the seller'. Match the heater to your pool type by reading the maker's specifications.
Voltage and electrical connections
One pick in this guide states a 240V voltage in its title, while others do not state a voltage. Voltage is an electrical specification that affects how the heater is wired. This guide never gives wiring instructions; a licensed electrician should connect the heater according to the maker's manual. Check the voltage requirement in the title and confirm with the installer.
Who installs and wires pool heaters
Propane pool heaters require a gas supply and electrical connections. A licensed gas installer should handle the gas line, and a licensed electrician should handle the wiring, following the maker's manual. This guide does not provide installation steps. The CDC and NFPA have resources on carbon monoxide safety for gas appliances, which are linked in the sources.
Rules to check before you buy: local code, permits and utility
Local building codes, permits, and utility rules can affect where and how a propane heater is installed. This guide does not cover these requirements. Check with your local building office and your utility to understand what applies to your property. The maker's manual and a licensed installer are the best sources for installation requirements.
Questions
Does this guide cover energy use, operating cost, sizing or installation?
No. This guide compares propane pool heaters on the details stated in each listing title, such as BTU output, pool type, and voltage, along with live prices. It does not cover energy use, operating cost, sizing, or installation because the catalogue has no data for them. For those, read the maker's sizing page and manual, and ask a licensed installer for advice.
What does the BTU figure in a title mean?
The BTU figure states the heating output of the heater as listed by the seller. It is a measure of heating capacity, but it does not indicate how fast a pool heats or what pool size it suits. This guide quotes the BTU figure as stated and never matches it to a pool size. Consult the maker's sizing page for guidance.
Can you install a propane pool heater yourself?
This guide does not provide installation instructions. Propane heaters require a gas supply and electrical connections, which should be handled by licensed professionals. A licensed gas installer should connect the gas line, and a licensed electrician should handle the wiring, following the maker's manual. Always follow local codes and the manufacturer's instructions.
Why do some picks not state a pool type?
Some listing titles do not name whether the heater is for inground or above ground pools. In those cases, this guide writes 'not stated by the seller' and does not guess. The title is the only evidence used. For a heater that fits your pool type, check the maker's specifications or ask a licensed installer.
What is the difference between propane and natural gas heaters?
Propane heaters burn propane stored in a tank, while natural gas heaters use a natural gas supply from a utility line. Both are gas heaters, but they require different gas connections. This guide covers only propane heaters, as stated in the title. The EIA has pages on natural gas and propane for more on each fuel.
