How do you size a pool heater?
Here are the steps to determine heater size:
- Determine the desired temperature of the pool water.
- Determine the average air temperature for the coldest month of pool use.
- Subtract the average coldest month temperature from the desired temperature.
- Calculate the pool surface area (length x width)
How fast will a pool heater heat a pool?
It depends on a few things to determine how long it takes a heat pump to heat a pool. However, overall a heat pump generally heats a pool after 24 to 72 hours by 20-degrees Fahrenheit. For smaller pools like a spa pool, the heat pump can heat a pool between 45 and 60 minutes.
How many BTUs does it take to heat a 30000 gallon pool?
Or approximately 100K BTU’s for every 10,000 gallons of pool water. For inground pools less than 20,000 gallons, small gas heaters like the Raypak 206K BTU output are suitable. Pools up to 30,000 gallons should look at the Pentair 300K BTU or higher, and pools over 50,000 gallons should look at the Hayward 500K BTU.
Is a higher BTU furnace better?
A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
Are gas pool heaters expensive to run?
A typical gas pool heater can easily cost $100 a week or more to run, doubling the cost of a pool without a heater. The bigger the pool, the more it costs to heat it.

How many BTUs do I need for a 20000 gallon pool?
That means that if you have a swimming pool that holds 20,000 gallons, it requires 166,000 BTUs to increase by one degree. Then divide this number by 24 to find how many BTUs you need to raise the temperature by one degree over 24 hours.
How much does it cost to heat a pool per month?

Can I leave my pool heater on all night?
We have found that turning the heater off at night allows the water to cool rapidly. The heater then has to burn at a higher rate in the morning to make up the lost heat. The higher you turn the burner the lower the heating efficiency and the greater the heat loss from the exhaust gases.
Should I run pool heater overnight?
This is because the heat pump converts the warmer ambient air and transfers that to your pool. As far as energy efficiency goes, you’d want to run it during the day. Now, if you’re looking to swim in the morning, and you want it at 85 degrees in the morning, you’re probably going to have to run it at night.
