Propane Usage Of Pool Heaters

If this is your first time using a propane pool heater, you should know its usage limit. A pool heater is among the appliances that use high capacity. It can consume approximately four propane gallons per hour. Every gallon can operate a pool heater of 100,000 BTU every hour. Meaning to says, 4 gallons of propane can run a 400,000 BTU pool heater per hour. 

The BTU stands for British Thermal Unit. This is the capacity needed to increase the water temperature to degrees Fahrenheit. About 21,000 water gallons are contained in most pools. Each water gallon amounts to 8.34 pounds. This means that about 175,000 Btu is needed to increase the pool water temperature by one degree. As such, using your pool heater with 400,000 BTU for one hour will increase the water temperature by 1.82 degrees in maximum. In other words, the four propane gallons will be used by the pool heater to raise the temperature by 1.82 degrees.

So, how much propane does a pool heater use? For every gallon of your propane gas, you will incur costs of about 2.50 dollars. So using the heater to heat the pool for one month will consume propane costing 100 dollars. But calculating the cost is much more than that. The price will also depend on the size of the tank. 

If you select two tanks of 100 gallons of propane or one tank of 250 gallons of propane, the heater should be away from the tank by 10 feet. The cost of the fundamental installation of this tank will range between 350 and 500 dollars. Aside from that, you also need to pay the rental fee every year. The total cost of the propane tank and its installation will cost you at least 2,000 dollars. 

You can also consider getting those ground tanks. However, this will cost you a bit more. Nonetheless, it will be worth it once it begins heating the pool. On average, ground tanks costs about 3,500 up to 5,500 dollars. But before you proceed with the installation, know the tank limitations first. Ensure that it is away from your property line by about 10 feet. Follow the same guideline to any objects that might ignite. Since most pools are in the backyard, it can be hard to follow this condition. 

Furthermore, the tanks need to be put away from tree roots while ensuring that your propane company can quickly reach their delivery hose. Usually, delivery hoses measure about 130 up to 150 feet. At first, you will think that you are spending more money. But this will let you purchase more gallons of propane.
