On average, natural gas burns about 1 therm per 100,000 BTUs per hour (
As long as you are willing to wait for the pool to heat, it is cheaper to turn off the heater when you aren't using the pool. BTUs are BTUs. The pool needs a certain amount to heat to a certain temp and will lose a certain amount.
The average cost to heat a pool can range anywhere from $300 to $1,000 per month, depending on the size of the pool. Don't stress though, there are plenty of ways to heat your pool for a lot less.
A 100,000 BTU heater uses 1 therm of natural gas per hour, so a 400,000 heater consumes 4 therms an hour. 4 therms an hour x $1.67 = $6.68 per hour. So the magic number based on the most common 400,000 BTU pool/ spa heater is $6.68 per hour in gas cost to run your heater.
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.
Cost of Running a Propane vs.
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.
If you want to get as much time as possible out of your pool, however, a heater is a good investment. With a pool heater, you can easily be swimming May through mid-October, giving you a good five months of use out of your pool. That's literally double the amount of time you'd get without one.
It depends on a few things to determine how long it takes a heat pump to heat a pool. However, overall a heat pump generally heats a pool after 24 to 72 hours by 20-degrees Fahrenheit. For smaller pools like a spa pool, the heat pump can heat a pool between 45 and 60 minutes.
A pool that is uncovered can lose up to 5 degrees F overnight; a good cover can cut that loss by half. Used at night or whenever your pool is not in use, the pool cover can help save fuel costs by cutting heat loss regardless of the type of heating you utilize.
So, how much electricity does a pool heat pump use? About 5 kilowatts per hour per 100,000 BTU heat pump. For a general 100,000 BTU pool heat pump, the power you`ll utilize is approximately 5,000 Watts per hour. Typically, the National average for power stands at 13 cents for every kilowatt-hour.
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.
Compass Pools estimate an average running cost of 50p per hour for a swimming pool heat pump, which will likely run at anything from 4 hours to 8 hour a days, meaning daily running costs of around £5 a day in summer and £10 a day if using year-round for heating plus chemicals.
The efficiency of the heater? Physicist: The correct answer is always to leave the heater off for as long as possible, as often as possible. The one and only gain from leaving a pool heater on is that it will be warm when you get in. The same is true of all heaters (pool, car, space, whatever).
Not only will it be tough to keep the heat in your pool on colder nights but you will also spend a fortune trying to heat your swimming pool. So unless you have money to burn, it's best not to run your heater at night on an uncovered swimming pool.
The fastest way to heat your pool is to use a gas pool heater and a solar cover. It's like heating up your coffee in the microwave and putting a lid on it. No matter how you plan to heat your pool, you should at least have a solar cover (or liquid solar cover) to help you retain the heat.
According to the World Health Organization, water temperatures ranging from 78 to 86 degrees Fahrenheit are generally comfortable and safe for those engaging in moderate physical activity in a pool.
While adding a pool heater requires an upfront investment, it helps you maximize your investment by being able to use your pool for much more of the year. Between setup and operating costs, a pool heater costs between $300 and $5,000, with the average cost around $2,000.
Pools up to 15,000 gallons should look at the Pentair 125K BTU or higher, and 20,000 gallon above ground pools should look at the Raypak 150K BTU.
We have found that turning the heater off at night allows the water to cool rapidly. The heater then has to burn at a higher rate in the morning to make up the lost heat. The higher you turn the burner the lower the heating efficiency and the greater the heat loss from the exhaust gases.
Gas pool heaters are relatively inexpensive to install, starting at $1,500. Prices for gas pool heaters can range from $1,500 to $6,000 on average, with larger pools requiring more powerful and expensive heaters.
Solar Heaters
The next cheapest way to heat a pool is through a solar heater. The cost of running a solar pool heater is essentially free, aside from occasional maintenance. The difference is that a solar heater is a lot more expensive to install – often even more expensive than a conventional heater.
Heat pump pool heaters cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters. Therefore, you'll save more money in the long run.
Yes, you can add a pool heater to an existing pool. It is not uncommon for homeowners to have the desire to heat their backyard pools later in life. You can choose from gas/propane, solar or electric heat pumps that are suitable for heating your current pool.
A pool heat pump should not be left running all the time. For one, you are wasting electricity by keeping it on when your pool is already warm enough. Also, this will lead to an increase in energy costs month after month.
