about how to heat the water in the basin need to think at the stage of its design, for all the technological elements of the system are interrelated.Experts recommend installing heaters in combination with other equipment for the pool, but even if such works were not carried out, the heating system can be build later.

It should be noted that the temperature of water in swimming pools for adults should not be lower than 24-26 degrees, and for the children of this parameter is even higher - at least 30 degrees.


method of heating water in artificial reservoir ↑

There are four ways to heat the water in the pool:

  1. Flow heaters
  2. Heat
  3. Solar collectors
  4. Heat pumps

choice of equipment depends on several factors:

  • volume pool
  • water for heating
  • regular communication features in the house
  • on the preferences of the customer.

So, to find out what is the best type of heating equipment will fit harmoniously in your pool, analyze each "to pieces."

Flow heaters for small pools ↑

Flow heaters - the most simple and relatively inexpensive way to heat the water in the pool.They are intended for heating a continuous stream of fluid with the minimum pressure drop.This type of heating equipment is compact, so it does not require the installation of a large technical room.A small covered booth will be just right.

housing electric heaters made from high-quality plastic, titanium or stainless steel, and the heating elements themselves - stainless steel alloy that can withstand relatively high temperatures.

Choosing a flow heater, be aware that its power should correspond to the volume of water in the pool is small and shallow pool, located in a heated room, it does not require the purchase of a large and powerful machine, for it will be enough and 3 kW.

Although when it comes to power, the flow-through heaters can not boast of this parameter - the maximum that they can squeeze out of yourself - it is 18 kW, which is not enough for a large outdoor pools.So, if your pool has a volume of more than 36 cubic meters.meters and it is located in the street, the purchase of such equipment would be an unjustified waste of money, because even the most powerful of the range of electric heaters can not cope with its task.

In addition, the house can be a limitation on the power or wiring does not meet all the requirements to establish such a unit then also makes no sense.

Benefits flow of electric heaters:

  • rapid heating of the pool
  • possible to adjust the temperature by thermostats
  • availability of some models of the flow sensor, the trip display in the absence ofwater circulation
  • automated monitoring system
  • small size


  • low power
  • large energy bills
  • inability to install in homes with limited power

exchangers - simple economical equipment ↑

exchangers (in principle, it is evident from their names), unlike electric heaters do not consume electricity.Their work - heating the pool water by connecting to a shared heating system at home.

This machine is a flask inside it coil through which hot water is moving.This water is supplied to the heater of the heating system by means of a circulating pump whose operation is governed by the special valve.In turn, the valve is controlled by a thermostat.The very same coil is washed with cold water from the basin.In principle, everything is very simple and clear.

master of all this equipment is only set on the thermostat the desired temperature to him, all the rest of it will make automatic.

heat exchanger capacity can vary from 13 to 200 kW, which is significantly greater than that of electric heaters.Power selection in this case depends on the amount of water in the pool, because the longer it is, the longer should operate the heater.

first warm water with heat exchanger lasts for about 28 hours at the maximum possible for him to power.This is in order to avoid collapse of the instrument (structural changes in the heater housing and its internal components) which may occur due to too fast heating water.

After the first start of the unit will only maintain the required temperature, it saves money.

As a rule, the heat exchanger is disposed between the pumping stations and disinfection system to avoid damage due to the presence of chlorine in the water.If too much water is chlorinated, it is recommended to install titanium heat exchangers.

advantages of heat exchangers:

  • significant savings
  • ease of management
  • high power


  • long water heating

Solar (geliosistemy) ↑

sun - an inexhaustible source of energy, only tamed him recently and immediately found application - began to heat homes, apartments, warehouses, and finally got to the pool.

course, the water in the basin can heat itself under the rays of the scorching sun, but what if your pool is under cover or indoors?Then the sun comes to you!

Solar collectors and solar modules are of cones, tubes or screens that take up the rays.Each module is individually able to heat up to 30 cubic meters.meters of water, then the greater the volume of your pool, the more you need the modules.

The principle of the collector: the sun's rays falling on the collector, which usually is black, it is completely absorbed.The coolant, inside the reservoir, heated to 140 degrees, and then starts the circulation pump, which is located in the storage tank.Naturally the water is almost instantly becomes hot and can be used for swimming pools and for heating and hot water at home.

Any such reservoir models, which are integrated in the sensors and automatic three-way valve, through which water is automatically routed to the heat exchanger.Upon reaching the desired temperature, the water will pass heat exchanger, gradually cooling down.And having reached the minimum value (which is set by the owner of the pool), the water will flow back to the heat exchanger and the system will start anew.

solar collector

Advantages of solar collectors:

  • rapid heating of water
  • convenient system control
  • multivariate uses: space heating, water heating in a pool, to supply the house with hot water


  • in cloudy weather collector efficiency is reduced, thereby reducing the heat transfer coefficient

Heat Pumps: Power and speed ↑

Heat pumps - a new and rather unpopular (yet) for the Russian method of heating waterpool.The lack of interest from buyers is easily explained - the high price of this type of heater.

heat pump operation on the principle of a multi-stage transfer of heat from different heat transfer via condensation, compression of different gases, etc.

As an initial heat source can be used for household and industrial waste water after treatment, warm thermal water and groundwater, the water of lakes, rivers, the heat that is released during flue gas cleaning and in general any sources of heat, the temperature of which at least one or two degrees abovethan the water in the pool.

principle: on the outer pipe located under the ground, with the help of the circulation pump is pumped hydraulic fluid, for example, a mixture of water and antifreeze.At the exit of the liquid tube through the soil temperature becomes a few degrees warmer.Thereafter, the mixture is sent to a heat exchanger (evaporator), where it gives up its heat to the refrigerant, which immediately begins to boil (it is enough to barely lukewarm water) and is converted into steam.This steam enters the compressor, which compresses it to 20-25 atmospheres.During this process, there is a sharp increase in temperature to 55 degrees.

It is this energy and sent to the future for heating homes or heating water in the pool.

This system works in a vicious circle: when the hydraulic fluid and coolant To fulfill its mission, they passed through the cooling stage, meet again,to start the cycle over again.Thus, it appears that the bulk of the energy is spent on the work of the compressor.

heat pump can not only heat the swimming pools, but also provide a warm holiday huge area of ​​300 square meters.meters.

advantages of heat pumps:

  • high power
  • rapid heating of water and space heating
  • use of free energy sources (geothermal, water. Sewage, etc.)


  • high cost

Well, as heated swimming pool, and with the help of which you can do, now you know.It remains only to weigh the "pros" and "cons" and make the right choice.Good luck in the construction and repair!
