How much does it cost to heat a 12000 gallon pool?
80 cents. To heat an average pool (10-12K Gallon) with no solar cover, typically expect 1 to 1.5 degrees of change per hour By adding a solar blanket to your pool during heating you will greatly increase the efficiency of the heating process and keep evaporative heat loss to a minimum.
How much BTU does it take to heat a 20 gallon pool?
Now, divide this Btu total by 24 (hours) to determine the Btu/hour required to heat the water: This means that it would take 207,500 Btu per hour in order to raise this 20,000 gallon pool from 50 degrees up to 80 degrees in a 24 hour period of time.
How long does a gas pool heater take to heat?
The 175,000-Btu heater would take 28.45 hours to accomplish what the 207,500 Btu heater can do in only 24 hours. This is actually how a solar heater (or an electric heat pump) works to heat a pool. Unlike gas heaters, they have much lower Btu output potential, nowhere near to 200,000 Btu per hour.
Which is the least efficient pool heater to use?
Solar pool heaters produce the lowest Btu output of any type of pool heater. However, solar heating also has the lowest cost per Btu since they heat water using the warmth of the sun. Note: Using a heating element to heat water, like you would find with an electric kettle or a traditional hot tub heater, is the least-efficient method.
How much does a solar pool heater cost?
These models generally cost about $1,000 more than the plain heating models. A heat pump with capacity of 130,000 BTU/hour will take about 48 hours to heat the 30,000 gallon (20′ x 40′) pool in the examples above and would need a cover to be able to maintain the temperature. Solar pool heaters are a different kettle of fish.
How to calculate the BTU of a pool boiler?
Finally, subtract (b) from (a) which will tell you how much you want to be able to heat the pool. You can now calculate your ideal theoretical BTU rating as follows (assuming (a) an average 3.5 mph wind speed at the pool surface, and (b) a 0.5 to 0.7 ºC temperature rise per hour).
Do you need a boiler for a swimming pool?
In the same way, going for the biggest gas boiler with a virtual computer attached is seldom necessary for the average home-size swimming pool. However you may like to go one size up from what the BTU calculation says to have a margin of error for cold snaps There You Go Baffling Me with Science. What’s a BTU?
How many BTUs does a pool heater need?
A BTU or British Thermal Unit is the standard for measuring heating capacity and most pool heaters will be described in terms of their BTU output. What we will do first is work out the number of BTUs you will need to increase the water temperature of your pool by 1⁰F in one day.
These models generally cost about $1,000 more than the plain heating models. A heat pump with capacity of 130,000 BTU/hour will take about 48 hours to heat the 30,000 gallon (20′ x 40′) pool in the examples above and would need a cover to be able to maintain the temperature.
