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.
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.
However, at night or on a sunless day, that water temperature can turn chilly. Fortunately, there's an easy solution: just add heat. A pool heater can be one of the best investments you make for your swimming pool. Heaters maintain your preferred pool temperature, and make the water more comfortable.
Indeed, most pool owners hire a professional to replace their pool heater. Many states require gas appliances to be installed by a licensed contractor; but buying it, placing it and plumbing it – you can do yourself.
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.
You can significantly reduce swimming pool heating costs by installing a solar pool heater. They're cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs. Actually, solar pool heating is one of the most cost-effective use of solar energy in some climates.
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 know those black trash bags? They can hold heat too. Fix one up to a hula hoop and if you want, cut one side of a pool noodle to add buoyancy and you've got yourself a super cheap pool heater.
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.
Use a gas heater
Gas pool heaters offer the fastest heating of all the options in this post. And that makes sense because just like a grill or oven, a gas heater creates heat by burning gas. But at the same time, they also have the highest monthly operating cost of all pool heating options.
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.
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.
Heat Pumps can help save you money!
This is a much more efficient way to heat your pool's water. To cool your pool's water, the process is reversed. In cooling mode, heat pumps pull heat out of the water and put it back in the air, when Mother Nature decides to turn up her thermostat.
Right now, an unglazed solar system can heat a pool to 78-85 degrees Fahrenheit without much effort. Solar pool heating panels last about 20 years, so in that scenario you could be looking at about 17 years of cost savings.
Solar pool heating systems can last 20-25 years or longer, so we also offer some extended warranty options for additional coverage.
If you are operating an Electric Pool Heat Pump it would take 2 days to reach 10 degrees and 5-6 hours of operation. If you are using solar heating it generally raises the pool water 2-4 degrees per day and cumulatively it reaches a 10-degree increase in 5-6 days and then maintains it.
Water Temperature
Using the heater only when the water dips below a certain point keeps the energy consumption down. For the average person, a pool that is 78 degrees or higher is comfortable. If you are trying to save money or energy, run your heater only when the pool water temperature dips below 78.
However, in the Northwest U.S., a pool heater might be necessary to extend the swimming season for a large above ground pool. If you only need to warm up your pool a few times a season, or the pool isn't permanently installed, using a liquid heat blanket could be sufficient.
Turning your pool into a spa is the best option. The spa uses the same plumbing and mechanical systems as your pool, so installation will not break the bank. Adding a spa will extend your pool usage beyond summer because of the high temperatures of the water. Your pool can be a hot spring this fall.
How Long Will a Concrete Pool Last? A concrete pool should last decades (we're talking 50 years or more) if it is properly maintained. While the shell of the pool can become damaged if the building was not done correctly, a well-constructed concrete swimming pool should last a lifetime.
It may be cheaper to run the pump at night, but honestly you should run it 1 hour a day per 10 degrees of temperature at least, and it should be during the day. Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up.
Since you lose more heat energy from a hot pool than from a cool pool, the most efficient thing you can do is keep the temperature as low as possible for as long as possible. The most energy efficient thing to do is always to turn off the heater.
