Despite the fact that most pool heat pumps are inverter type (with really low power consumption), there is a concern about the cost of energy to maintain an adequate water temperature.

If you share this concern, don’t worry, because there are really good alternatives for heating pool water for free, homemade and without electricity.

How to heat pool water for free

Despite what it may seem, there are many ways to heat the water in your pool without having to spend a single euro. Yes, if you choose the right materials for your pool, it will heat itself.

EPS block pool

EPS (Expanded Polystyrene) is a material widely used in housing construction since the 1960s due to its insulating properties. Specifically, laboratory studies indicate that EPS retains heat up to 255% more effectively than concrete with a 65% lower temperature loss.

In the structural design of our pool we can take advantage of the properties of high density EPS blocks, which will retain the heat of the water better than other materials such as concrete, brick, steel or fiberglass. It is considered a way to heat the pool water for free because you do not have to invest afterwards, only increase the cost initially.

If you are thinking of building a pool of high density EPS blocks and want a personalized budget, contact us without obligation.

You can heat the pool water without electricity if you install it with EPS blocks.

Larger filter

Larger pool filters have a larger surface area through which the water can flow, which means that the pump will not work as hard to move the same volume of water.

In addition, a larger filter surface will retain more dirt, which will reduce the number of backwashes. By reducing the number of backwashes, we conserve our pool water longer.

Remember, every time you add new water to the pool, we do it with cold water. If, in addition, you can install cartridge filters, you will save even more water, since they do not require sand backwashing and are cleaned with a simple domestic garden hose under pressure.

How to heat pool water with the sun

It is clear that the sun is our great ally for heating (whatever it is). In the case of swimming pool water, there are also ways to use this natural resource, starting with the most logical: solar panels.

Solar panels for swimming pools

There are now tremendously efficient solar water heating panels for swimming pools, such as OKU solar collectors. Its operation is simple: the pool water is conducted at low speed through solar panels that transmit the temperature of the sun, returning to the pool with a higher temperature.

A fantastic option for heating pool water for free without electricity.

The best way to heat pool water with the sun is with solar panels.

Build the pool in a sunny area

It seems logical, but when designing the pool, in many occasions the best location is not taken into account. A sunny pool has an energy requirement between 50-60% less than one installed in a shaded area. If you have a choice, install your pool in a sunny area.

Install a “dark” pool

Pool liners with darker colors absorb the sun’s rays better, which helps to heat the pool. If you don’t mind the dark color, opt for this option and you will save money on heating.

In addition, dark pools are very elegant in certain decorating environments. Easy, isn’t it?

One of the best ways to heat pool water for free is to install a black liner.

How to heat pool water without electricity

For users who want to heat a pool without a heat pump, we also have alternatives. Here are some of them.

Thermal blanket for swimming pool

Pool covers such as thermal blankets are the simplest solution to heat the pool water with the sun without electricity(raising up to 10ºC depending on the quality of the bubble cover). In addition to heating very efficiently, it prevents water evaporation. We recommend you read our article on the advantages and benefits of solar pool covers for more information.

How to heat a swimming pool at home

When you are looking to heat a swimming pool at home you are looking to heat the pool water for free. If you do not want to invest in systems, nature is your great ally. We already saw it with the sun, but there are even more ways.

Natural insulation around the pool

When designing the area around the pool, it is important to consider functional as well as aesthetic aspects.

Building a natural parapet around the pool can reduce wind exposure and therefore reduce heat loss from the pool. Few better ways to heat pool water for free at home will you find.

In addition, this type of solution helps to reduce evaporation of already heated water, resulting in additional savings.

To heat the water in your home pool, nothing better than surrounding it with hedges and trees.

Conclusion, is it possible to heat the pool water for free?

In short, there are several ways to heat the pool water without electricity and raise its temperature at home. Some are simpler than others, but all are effective.

An easy option is to opt for a dark liner that absorbs the sun’s rays, although the pool can also be built with insulating materials such as EPS or high-density XPS.

In addition, it is important to locate the pool in a sunny area to take advantage of the sun’s energy, install solar panels or a solar cover, and use larger pool filters to reduce the need for backwashing and thus the loss of cold water.

All these options allow you to save money on heating your pool, extending the swimming season in an economical and simple way.
