How many BTUs do I need to heat my above ground pool?
Heat Pump Sizing Chart – Above Ground Pools
| Pool Size (Feet) | Summer 4 BTU’s | Extended 6 BTU’s |
|---|---|---|
| Up To 10,000 Gallons Up To 21′ Round or 15′ x 26′ Oval | 50,000 BTU | 65,000 BTU |
| Up To 13,000 Gallons Up To 24′ Round or 15′ x 30′ Oval | 50,000 BTU | 85,000 BTU |
| Up To 17,000 Gallons Up To 27′ Round or 18′ x 33′ Oval | 65,000 BTU | 110,000 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 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.
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 do I calculate pool heat?
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 much does it cost to heat an above ground pool?
The Average Cost of Running a Pool Heater
| Type of Heater | Cost Per Year | Cost Per Month |
|---|---|---|
| Heat Pump | $700 to $2,400 | $120 to $200 |
| Electric Resistance | $2,100 to $7,200 | $175 to $600 |
| Propane | $2,500 to $10,200 | $200 to $850 |
| Natural Gas | $1,400 to $4,800 | $200 to $400 |
How do you calculate heater capacity?
Heat Capacity of an object can be calculated by dividing the amount of heat energy supplied (E) by the corresponding change in temperature (T). Our equation is: Heat Capacity = E / T.
How much does it cost to heat a pool one time?
On average, natural gas burns about 1 therm per 100,000 BTUs per hour (British Thermal Units). Meaning, an average pool heater between 300,000 and 400,000 BTUs will cost anywhere from $3.30 to $4.40 per hour to heat your pool.
How much should I increase the heat in my Pool?
Please note that heat rise varies when dealing with different heaters. The usual recommendation is an increase of 1 to 1 and a half degree per hour. NOTE: Calculations are rough estimates as to which size pool heater you may need.
How to calculate the efficiency of a pool heater?
The usual equation for a rectangular pool is Length x Width x 1.6 equals total square feet Pool heater efficiency is expressed as a percentage, provided by the manufacturer, that represents the amount of energy a pool heater transfers to the water for each unit of energy (BTU) used to generate that heat.
How much energy does a pool heat pump use?
You probably read this quite often on the sides of pool heat pumps and typical air conditioning systems. While conventional heaters only achieve efficiencies of about 75%, a heat pump delivers on average about 5 times the heat absorbed. Nearly 80% of the energy needed to heat the pool comes from the ambient air.
How to calculate the size of a swimming pool?
Used to determine the approximate square feet of surface in the pool’s interior. The usual equation for a rectangular pool is Length x Width x 1.6 equals total square feet
