# Pool heater

A pool heater is equipment that warms pool water, usually gas or a heat pump.

A heater extends your swim season. In North Texas, spring and fall water can be cool, even when days are warm. A heater lets you swim sooner and longer.

The two main types are the [gas heater](https://marinapool.multisites.ai/glossary/gas-heater) and the [heat pump](https://marinapool.multisites.ai/glossary/heat-pump). A heater needs steady flow, clean water, and a balanced chemistry. Gas work and wiring are jobs for a qualified pro. Common faults include a failed [igniter](https://marinapool.multisites.ai/glossary/igniter), a bad [pressure switch](https://marinapool.multisites.ai/glossary/pressure-switch), and scaled [heat exchanger](https://marinapool.multisites.ai/glossary/heat-exchanger). Marina Pool Services repairs pool heaters.
