How many kW Do I need to heat my pool?
Heat pumps will use around 5,000 watts or 5 kilowatts per hour per 100,000 BTU’s. For a typical size 100,000 BTU heat pump, that’s 5 kilowatts per hour.
How many BTUs do I need for a 20000 gallon pool?
166,000 Btu
20,000 gallons x 8.3 lbs / gallon = 166,000 lbs of water that needs to be heated. Since it takes one Btu to heat one pound of water by a single degree, we now know that raising this entire 20,000-gallon pool by one degree will require 166,000 Btu of heat energy.

Can you oversize a pool heater?
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.
