Gas pool-heating is a popular choice with pool-owners, for excellent reasons, and is definitely one to consider if you already have a natural gas supply to

Basically they are the same as a central heating boiler, plus a heat-exchanger to transfer the heat into the pool-water

Gas heaters warm a pool quickly, and fairly efficiently, but it is vital that they are installed by a qualified gas engineer in accordance with the appropriate gas regulations 

Using a gas-fired heater with an electric heater running on an economy tariff at night is more economic than relying on gas alone

If in any doubt as to the competence of the installer, ask to see their up-to-date Certification.  A qualified, Professional Gas Installer will not be offended by this - they want to weed out the cowboys in their Industry

Warning: - Don't take any chances with installation because an incorrectly installed, or incorrectly vented, gas heater can release carbon monoxide (CO) and prolonged exposure to CO kills. That would be a bad start to any pool-party

Please don't be scared off by the warning above - gas heaters are very well understood technology and they work perfectly well. A correctly installed gas boiler is perfectly safe. There are millions of them working away, right this minute, in complete safety
