How do I calculate BTU for pool heater?

Multiply the surface area of the pool by the temperature rise. Multiply that result by 12 to arrive at the required Btu-per-hour output of the heater. This figure represents the heater output necessary to heat the pool to the desired temperature in 24 hours, based on an average wind velocity of 3.5 mph.

## How many kW Do I need to heat my pool?

kW power heat pump The heat pump should be able to heat the water by approx. 0.20 – 0.25 degrees per hour. It takes 1.16 Wh to heat one litre of water one degree, which means 11.6 kWh for a 10m³ pool. In other words, one kilowatt hour heats 862 litre of water by one degree Celsius.

How long does it take to heat a 20000 gallon pool?

You have a 20,000-gallon pool and use a 125,000 BTU heater. Your water is currently 70 degrees F but you would like it to be a minimum of 80 degrees F. How long will it take before the pool water reaches 80 degrees F? 10 x 1.33= 13.34 hours of heating before the pool reaches 80 degrees F.

### How many BTUs do I need for a 20000 gallon pool?

166,000 BTUs
Pool heaters measure their power in BTU (British thermal units). One BTU raises the temperature of one pound of water by one degree Fahrenheit. There are 8.33 pounds of water per gallon. That means that if you have a swimming pool that holds 20,000 gallons, it requires 166,000 BTUs to increase by one degree.

How much gas does a 400k BTU pool heater use?

4 gallons an hour
For a typical size 400,000 BTU heater, that equals 4 gallons an hour.

## Does a pool heater use a lot of electricity?

What size heat pump do I need for a 50000 Litre pool?

18KW
Find the volume of your pool, and pick a heat pump model with heating increase of 0.25 and above. The higher the number, the faster your pool heats up. For example, if you have an 50,000L pool then the minimum recommended size would be the 18KW model (0.27c per hour).
