How much natural gas does a pool heater use?
Natural Gas Pool Heaters Natural gas heaters (also known as NG heaters) use about 1 therm per hour per 100,000 BTU’s. For a typical size 400,000 BTU pool heater, that’s 4 therms per hour.
How much gas does a 400k BTU pool heater use?
Here’s why: the average propane pool heater burns about 1 gallon of propane per hour per 100,000 Btus. Since a propane pool heater for a standard-sized pool (~21,000 gallons) outputs 400,000 Btus, you will burn about four gallons of propane per hour.
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.
What size gas line do you need for a pool heater?
| Distance from outlet of | H150 | H250 |
|---|---|---|
| gas valve inlet | Pipe | Pipe |
| 0 to 50 ft. | 3/4″ | 1″ |
| 50 to 100 ft. | 3/4″ | 1″ |
| 100 to 200 ft. | 1″ | 1 1/4″ |
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.
Can you heat a pool with natural gas?
Natural gas heaters will heat your pool faster than electric or solar heaters, and unlike the latter they don’t require clear skies to run. Whether it’s day or night, natural gas heaters will heat your pool to the perfect temperature.
How many kwh does it take to heat a pool?
You can figure about 5,000 watts or 5 kilowatts per hour per 100,000 BTU’s for a heat pump. For a typical 100,000 BTU heat pump, that’s 5 kilowatts per hour.
How many BTUs do I need for a 15000 gallon pool?
Heat Pump Sizing Chart – Inground Pools
| Pool Size (Feet) | Summer 4 BTU’s | Spring & Fall 5 BTU’s |
|---|---|---|
| Up To 15,000 Gallons 14′ x 28′ | 85,000 BTU | 85,000 BTU |
| Up To 20,000 Gallons 16′ x 32′ | 85,000 BTU | 110,000 BTU |
| Up To 25,000 Gallons 18′ x 36′ | 110,000 BTU | 125,000 BTU |
| Up To 30,000 Gallons 20′ x 40′ | 125,000 BTU | 150,000 BTU |
How many BTUs do I need for a 10000 gallon pool?
Sizing a gas heater for inground pools is done by first matching pool heater BTU output to pool size in gallons. 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.
How much does it cost to install a gas line for a pool heater?
Depending on the type of pool heater you choose, you may have to install some necessary hookups. Gas heaters may require a new gas line, which will cost $350 to $800.
How do I calculate the gallons in my pool?
Length x width x average depth x 7.5 = volume (in gallons) Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic meters. If you’d like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
What size heater do I need for 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 many BTUs does a gas pool heater use?
When it comes to gas pool heaters, this is mostly true. However, it really depends on your pool size, and budget. Generally speaking, the amount of BTUs required to heat pool water will be the same, no matter the size of the heater.
How much heat should a pool heater increase per hour?
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. Consult with a certified pool installer to verify the minimum heater size required.
How do you heat a pool with a 12 degree heater?
For this example we’ll use 73°F. Subtract this temperature from your desired temperature of 85°F. Next, divide the 12°F by 8, which is the number of hours required to fully heat the pool. So, the heater has to raise the water temperature 1.5° per hour in order to heat the pool in 8 hours.
What is the formula for sizing a gas heater?
The formula for sizing a gas heater determines the heater’s British thermal unit output per hour required to heat the pool to the desired temperature in 24 hours. Figure the surface area of a typical rectangular residential pool by multiplying the length in feet times the width in feet.
