A pool heater can be undersized: if it cannot replace the heat lost through evaporative cooling, the pool’s temperature will fall below the ideal. However, there is no such thing as oversizing a pool heater. The larger the heater’s output, the faster it heats the water in the pool, and it will not begin short-cycling.
