How do I know what size pool heater I need?
The pool’s surface area divided by three gives you the minimal BTU size recommended for that particular surface area. Continuing the example above with the 15 x 30 pool, after dividing by 3, you get 150. Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs.
How many BTUs do I need for a 20000 gallon pool?
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.
How many BTU do I need to heat my inground 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.
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.
Are pool heaters expensive to run?
The size of your pool also matters, with larger pools costing more to heat than smaller ones. On average, however, a gas heater costs around $200 to $400 a month to run. Electric heat pumps cost less, coming in at about $100 to $200 a month.
What is the cheapest way to heat a pool?
Here are the seven cheapest ways to heat your pool this off-season.
- Use a Solar Cover.
- Invest in Solar Sun Rings.
- Try Out a Liquid Solar Pool Cover.
- Build a Windproof Pool Enclosure.
- Use the Black Hose Trick.
- Snag a Pool Heat Pump.
- Combine a Solar Cover and Pool Heat Pump.
What is the average life of a pool heater?
You can expect a gas or heat pump pool heater to last 8 to 11 years, with an average of 10 years. Regular usage and maintenance is key to a longer lifespan.
What is the best heater for a pool?

- Pentair 460737 MasterTemp: Best propane pool heater. (Image credit: Pentair )
- EcoSmart Smart Pool 18: Best electric pool heater.
- Hayward HeatPro HP21404T: Most economical pool heater.
- Hayward H-Series H250FDN: Best natural gas pool heater.

Should I run pool heater overnight?
Conclusion. It is not advisable to heat your pool at night because of the time and energy it will consume. You’re advised to heat your pool during the day for more efficiency, and if you can, buy a solar blanket to retain the temperature of your pool.
Should I oversize my pool heat pump?
Generally speaking, you should oversize the heat pump as much as possible. You’ll never regret going too big, as doing so means warming the pool at a faster rate without running the heater as much.
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 do I choose a pool heater?
Choosing the perfect pool heater will depend on where you live and what type of heat source is available to your home.
- If you live in the north with access to natural gas, choose a gas heater.
- If you live in the north with no natural gas, invest in a heat pump.
