Solar pool heating is a great way to enjoy a warm, heated pool all year round. It has been proven that solar heating is more cost effective than conventional methods and it can provide up to 90% of your pool’s heat needs.

But how hot does solar water heater get? This blog post will answer this question and many others you may have about the benefits of using solar for your swimming pool or jacuzzi!

Solar pool heating success – 30 degrees temperature increase

Increase the temperature of a 45 000 gallon in ground pool by over 30 degrees using nothing but solar heating. The idea behind solar heating is pretty simple – you take the heat that the sun naturally provides and you transfer that heat directly into your pool.

In essence, it’s a low cost system that’s going to heat your pool. When you compare a solar heating system to a traditional gas or electric system, the costs are fairly minimal. There’s virtually no upkeep that you need after you install.

Solar pool heating really works well

When you compare that to a traditional gas or electric system, you have your utility bill that you have to deal with, which is going to be an ongoing cost. One of the other great things about the solar heating system is it increased the swim season for me.

Previously, my swim season was basically the summer months, where I only had a few months to swim, and even then without the solar heating system in place or any heating system in place, it was fairly difficult to go swimming.

Without a heating system my pool would be 62 to 65 degrees, which was just wasn’t realistically tolerable. Now, the swim season is essentially from the beginning to mid-April, all the way to the end of October – sometimes early November.

I’ve had the solar heating system in place for the last two years and it’s been working great for me. Let me take you over to my pool now and show you what the temperature was when I took it in early early march or mid-march and what it is now, keeping in mind that this is still early in the swim season.

It’s just past Memorial Day in May, so the swim season is just getting started. I’m not hitting peak temperatures in my pool just yet. In mid-March there was about 55 degrees, which was just not tolerable. This was before applying any heating during the off-season .

Let me show you the what the heating system looks like. It’s about 82 degrees now and I’m still expecting another five or ten degrees once the heat of the summer kicks in.

Initially, I added a solar blanket or solar pool cover. When you add a solar pool cover to cover your pool completely, the first most important thing that it does is it helps retain the heat that your system initially produces.

So if your pool heats up at night, you don’t want to lose all that heat through evaporation. You want to continue to heat your pool progressively. As it gets warmer and throughout the the summer, you want to absorb as much heat from the sun as possible and retain that in your pool.

Secondly, if you look closely at a solar pool cover you’ll see that there are these little bubbles and each of those bubbles does help transfer some of the heat from the sun directly into your pool, warming it a bit a few degrees.

It isn’t terribly critical but it does help both in taking in some heat as well as retaining the heat. The second step that I took to increase the temperature of my pool was to add a solar pool heater.

Now you’ll see a lot of these prefabricated in some of the big box stores or online retailers. They’re these wide blanket-looking plastic sheets that you connect to your system. You let the the sun beat down on it, it absorbs the heat and pushes it back into your pool.

So that was the second step that I took. You want to make sure you take a look at the reviews see what other people are saying about those. You don’t necessarily need to buy the most expensive item.

The solar blanket that I bought was mid-tier and it works pretty well . The same for the solar pool heater I got. I purchased one that had more heavily favorable reviews to help with the heating of the system.

I’ve seen a lot of people connect these directly to their to their pool pumps and that caused some issues. I connected the prefabricated heater to my pool return. I’ve got a return and I’ve some some pvc hooked up to it and you’ll also see I have an on and off switch.

The way it’s set up is it’ll return through the pool here and as it returns you can see that I have a pvc pipe that goes up. It comes comes along here and it goes up, ultimately going to the top of my deck.

I have an on and off switch here – this allows me to open it and shut it down, and divert the water straight through to the solar pool heater. When it’s night time and I’m running the pool pump, I don’t want to necessarily run that because the the ambient temperature is colder than my pool. So I can just open it up and let it function as a standard return.

The first year I had the prefabricated system, it did increase temperature in my pool but not as much as i wanted it to. I wanted it in the comfortable mid-80s, so what I did as step 3 is to add some additional heating elements.

Rather than use the prefabricated heater, I used copper, so you’ll see here I added right after the the prefab heater – it goes through some copper piping. I have added about 35 feet of copper piping that absorbs the temperature of the sun, just like a solar pool should.

From there it shoots that back into my pool. That’s how I was able to get the 30 degree increase in my pool temperature. I’m not a licensed plumber. I was fairly new to pvc gluing when I started this project but I was able to manage.

These three steps – the solar blanket, the prefabricated heater, as well as the the addition of the copper heating – with these three three steps I was able to increase the temperature of my pool by over 30 degrees.

Is solar pool heating worth it?

Solar pool heating is worth it because of its many benefits. First, solar water heaters are made from all natural materials which means they do not contain any harmful chemicals that can leach into the environment and contaminate groundwater like some other sources such as propane or gas-fired hot tubs with conventional systems would emit gases containing volatile organic compounds (VOC).

What is solar pool heating?

Solar pool heating is a system that heats the water in your swimming pools or jacuzzi by using solar energy. This type of heater makes use primarily on sunlight to heat up and maintain temperatures, which can reduce electricity consumption from other sources such as natural gas-fired hot tubs with conventional systems because it does not require any fuel input like fossil fuels for example would need.

The sun’s rays are focused onto tubes containing fluid (typically an antifreeze mixture) where they then absorb this thermal radiation before being converted into usable warmth at night – even when there isn’t enough power available through sunshine during cloudy weather days; therefore increasing its efficiency levels significantly over those found among traditional furnaces fueled solely off oil/gas coils too.

How effective is solar pool heating?

Solar pool heating is extremely effective in hot climates with limited cloud cover. The heat it can generate and maintain on a daily basis will be far greater than what you could get from the same surface area covered by solar panels because pools have large surfaces that absorb more sunlight energy over long periods of time.

This translates to higher levels of thermal radiation being emitted back into them as well! So this means there’s no need for any type or form fuel input whatsoever – even when cloudy conditions are present; therefore increasing its efficiency significantly above those found among traditional furnaces fueled solely off oil/gas coils too (which require constant monitoring) due to their lack luster performance capacities during these types weather outlooks instead.

How much does a solar pool heater cost?

How do solar pool heating systems work?

Most solar pool heating systems consist of a series or loops and tubes made from plastic, copper piping that are either laid on top the ground around your swimming pools perimeter lines (on gravel) with some an access point to be able remove them during cold weather periods.

These pipes can also go underground in order for you place these coils beneath any surface types as well; this is most commonly done by those who have above-ground type ponds/pools where they want their thermal energy capture levels increased considerably.

Does solar pool heating work in winter?

We all know how wonderful it feels to jump into a pool on a hot summer day. But what about when the winter weather sets in? When you have an outdoor pool, the best way to keep warm is with solar heating. Solar energy can be used year-round, and doesn’t require any additional heating costs.

There are three main types of heaters for pools – gas heaters, electric heaters and solar panels. All of these methods will work if they’re properly maintained so that your water stays at the right temperature throughout the seasons.

Do it yourself solar pool heating?

One popular do-it yourself project is to use a pool cover. This won’t heat the water itself, but it will trap in any existing warmth and stop cold air from sinking into your swimming space.

There are also other ways of blocking out that chilly breeze without using chemicals or electricity – for example installing blackout curtains on windows near pools can make them more energy efficient when exposed sunlight cannot reach through glass panes directly onto their surface area.

How to install solar pool heating?

Solar pool heating can be installed at your home in a number of different ways: from an above-ground panel to the ground or below, for example. The type you choose will depend on how much space is available and what kind(s) work best with where they’re placed.

Installing solar panels requires that there’s enough open area around them so as not block its exposure – this might mean getting creative about placement.

How to use solar to heat a pool?

Solar pool heating is done through a combination of solar radiation and convection – which can be achieved by using the sun’s power to transfer heat from one place (such as your roof) without transferring it directly onto whatever surface you’re wanting heated.
