The Pentair 462042 UltraTemp ETi Hybrid Pool & Spa Heater is two heaters in one cabinet: a 108,000 BTU heat pump running at a COP of 5.8, plus a 110,000 BTU propane gas heater.
The logic is straightforward. A heat pump is dramatically cheaper to run but slow, and it loses output as ambient temperature drops. A gas heater is fast and weather-independent but expensive per BTU. The hybrid runs on the heat pump for everyday temperature maintenance - where the 5.8 COP does its work - and fires the gas section when you want fast heat-up or when the weather turns.
Combined, the two sections deliver roughly 218,000 BTU. Ratings across conditions are 108,000 BTU at COP 5.8 (80/80/80), 100,000 at 5.6 (80/63/80), and 70,000 at 4.0 (50/63/80), so the system degrades gracefully as air temperature falls rather than failing to keep up.
