Everyone would like to be able to enjoy a swim in a heated pool when the temperatures are no longer so good. However, the heating of the pool requires a prior study by a professional so that the temperature of the water is as we had desired.
In fact, carrying out a thermal study is essential to be able to correctly choose a heat pump for your pool. Ideally, the heat pump should never be too big or too small for the customer’s needs.
In order to make a correct choice, you must, as a user, ask yourself a series of questions. Keep in mind that each case is different and the heat pump chosen by your neighbor or your best friend will probably not be the one you need. Now you will understand why. Take note.

How to choose the ideal heat pump for the pool?
Aspect 1: Use of the pool
You must ask yourself what exactly you are looking for with the heating of the pool. Generally, there are two types of users:
- those who want to use the heated pool all year round and
- those who only want to extend the bathing season.
In other words, let’s say you live in Madrid and your bathing season is generally from June to September. Well, if you are the second type of user, it is possible that what you are looking for with the heating of the pool is to bathe from April to October, for example.
Aspect 2: Geographic area
You have to analyze, for your specific geographical area, what is the lowest temperature.
For example, if in the previous point you are user 1 (you want to swim in the heated pool all year round), determine what is the lowest temperature that usually exists in your geographical area throughout the year.
If, on the other hand, according to the previous question you are a user 2 (you want to extend the season, before and after the summer), ask yourself what the lowest temperature is, for example from April to October in your area of residence.
Aspect 3: Desired temperature
It may seem obvious, but not all people enjoy the temperature of the water in the same way. Think and determine what is the ideal water temperature for you: 20 degrees? 25 degrees? 30 degrees? There is no correct answer, as it is a very personal choice.
Keep in mind that the water always tends to reach the temperature of the air, so that the greater the difference in temperature between the heated water and the outside air temperature, the greater the heating power you will need to maintain the temperature of your pool.
Once the user answers these 3 basic aspects about the heating of his pool, now it is the turn of the builder or pool owner, who must study a series of factors.
Factors to take into account in the Thermal Study
Factor 1: Pool Situation
It is vitally important to analyze at what exact point the pool is located: Is it sheltered from the wind by surrounding vegetation or by the construction of the house itself?
You should know that pools that are more sheltered do not receive as much wind blowing, so they lose less heat. (Now you will understand why you and your neighbor, living in the same geographical area, may need different heat pumps, if one has the pool surrounded by vegetation and the other far from the house, in the middle of a lonely piece of land).
Factor 2: Auto Cover
Pools that have an automatic cover have the advantage that their water will lose less heat. Consequently, it is a good idea to choose to add an automatic cover if we know that in the long run we want to heat the pool.
Factor 3: Pool Design
If the design of the pool includes an overflow, either lateral or perimeter, it must be considered that the temperature of the water will lose more heat easily. Why? Because when the water overflows and falls into the channel, it ends up cooling and inevitably losing heat.
Factor 4: Pool Dimensions
A widespread error is to consider that it is the m3 of water that must be taken into account when choosing a heat pump. This belief is not entirely correct.
What you should consider is the surface area of your pool’s water sheet, since the larger the surface, the greater the heat loss.
For example, the water in a pool with many m3 of water, a lot of depth and little surface area, will lose less temperature than a pool with a few m3 of water, less depth and a larger surface area.
How to choose the heat pump for my pool?
The principle by which heat pumps work is to obtain heat from the ambient air to transmit it to the water. So the colder the air is, the worse performance the heat pump will have.
In the market you will find a wide variety of heat pumps. Standard or more commercial heat pumps work up to 5º and are very inefficient.
From Godo Pools we recommend installing an inverter-type heat pump with an operating capacity of up to -15º. Although a priori it may seem that you do not need it, because perhaps in your geographical area the temperature will never be so low, they are super efficient heat pumps that always offer the best results.
You should also bear in mind that heat pumps for swimming pools work by thermal sensation. That is to say: 10º with high humidity will feel much colder and 30º with low humidity will feel like less heat.
Finally, if you have doubts when choosing a heat pump, remember that to know the degree of efficiency of a pump you have to compare the COP: capacity of the heat pump to produce heat in relation to what it consumes.
For example: A pump with a COP 5, will produce 5kw of heat for every 1kw of electricity it consumes. So we could say that it produces 5 times more than it consumes.
Taking all these factors into account and correctly comparing the degree of efficiency of heat pumps, we are sure that you will be able to correctly choose the ideal heat pump for your pool without making a mistake.
And remember, the most important thing is that no two cases are the same and the thermal study for your pool must be completely personalized.
