chicago-park-district-pool-3It’s depressing, but the swimming season is coming to an end. Depends on where you live, you may have months longer, but for us in Chicago, that is not the case.

If we want to swim past August or early September, we have two options – take advantage of an indoor pool at the park district, or invest in a pool heater.

OK, so it’s not that easy – you still have to figure out what in-ground pool heater is the best for your pool and for your lifestyle.

Let’s slow down a bit – there are three different pool heater types out there. Between Heat Pumps, Solar Heaters and Gas Pool Heaters, there’s a lot of homework to do, but luckily you’ve found this article.

Electric Pool Heat Pumps

Heat Pumps have a lower operating cost and emit no exhaust, as compared to natural or propane gas heaters. They need at least 45° outside air temp to produce heat, and are more expensive to buy than a gas heater. while the long-term cost is less than using gas.

Pool heat pumps are up to 97% efficient and run silent with the exception of the fan motor. They require no gas, which makes them safer to operate. Although they use very little power, heat pumps do need a lot of power, which may require the services of a local electrician.

Gas Pool Heaters

Pool heaters are available for propane and natural gas. Natural gas heaters connect to a home gas meter for the gas supply, while a propane heater runs on LPG from a storage tank; refilled regularly by a local propane delivery service.

Gas heaters can be either millivolt, or electronic ignition. Millivolt heaters have a standing pilot, but electronic heaters use a spark to light the pilot when needed.  Electronic heaters also have digital controls and diagnostics. Most (85%) gas heaters sold are electronic, but some people prefer the more mechanical millivolt control system.

The biggest benefit of gas heaters is speed of heating; they consistently raise the temperature about 1° per hour. Heat pumps and solar heaters take much longer to heat up, adding up to 5° per day, depending on the weather.

Solar Pool Heaters

Finally, solar pool heaters – harnessing the power of the sun, these heaters are great for both inground and above-ground pools. Economical and Eco-friendly!

Solar systems don’t require a professional to install gas or power, they are completely DIY. You can mount the panels toward the sun, or just lay them on the ground in a sunny spot near the pool filter.

Another type of solar heater is even easier to install – floating solar blankets, squares or rings are dual purpose, adding heat from the sun, and also helping retain the heat in the pool.

The 4×10 foot option can be mounted vertically or horizontally, while the 4×20 foot panel can only be mounted from horizontal position.

Purchase the optional bypass kit to turn off the solar heater during rainy weather.

Pool Heater Installation

Heat pumps and solar heaters must be installed outside, preferably in a dry, sunny area. Gas heaters can only be installed indoors or under a shelter if they are properly vented. For safety, it’s best to also install gas pool heaters outside.

Gas heaters should have the gas hook-up done by a qualified gas tech, and heat pumps should be wired and bonded by an electrician. The placement and plumbing for either is easily done by any handy pool owner. Solar heater systems can be completely DIY installed.

diving-man-from-clipartlogoJust because the temperature drops, or the sun starts to go down doesn’t mean you have to stop enjoying your pool. You can adjust to the weather accordingly with several heating options – from heaters to solar rings.

Depending on where you reside, and how large of a pool heater you install, you can add another 4-8 weeks onto each end of your swimming season.

Wherever you are, even here in the frozen north, you have options, and don’t have to worry about being restricted to just one pool heating solution.
