For a 50,000-litre pool (approximately 13,200 gallons), you typically need a pool heater with a capacity of around 250,000 to 300,000 BTU (British Thermal Units) for gas heaters, or a 15-20 kW electric or heat pump heater. The exact size depends on how quickly you want to heat the pool and your local climate.
