## How do I know what size heater I need for my pool?

To heat your pool by 20 degrees in just 12 hours (i.e. half the time), multiply the number of BTUs per hour by two. In our example this means that to heat your pool by 20 degrees in 12 hours you would need a heater with a capacity of 120,000 BTUs per hour.

**What size pool heater do I need for a 15000 gallon pool?**

Pools up to 15,000 gallons should look at the AquaPro 77K BTU or higher, and 20,000 gallon above ground pools should look at models like the TropiCal 115K BTU. Pools in very windy or colder areas, or those that don’t use a pool cover should consider installing one size larger.

### What size pool heater do I need for a 10000 gallon pool?

Heat Pump Sizing Chart – Inground Pools

---|---|---|

Up To 10,000 Gallons 12′ x 24′ | 50,000 BTU | 85,000 BTU |

Up To 15,000 Gallons 14′ x 28′ | 85,000 BTU | 110,000 BTU |

Up To 20,000 Gallons 16′ x 32′ | 85,000 BTU | 125,000 BTU |

Up To 25,000 Gallons 18′ x 36′ | 110,000 BTU | 150,000 BTU |

**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?

So, how much electricity does a pool heat pump use? About 5 kilowatts per hour per 100,000 BTU heat pump. For a general 100,000 BTU pool heat pump, the power you`ll utilize is approximately 5,000 Watts per hour. Typically, the National average for power stands at 13 cents for every kilowatt-hour.

**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).
