Heated pool. Heat pump. Equipment for swimming pools

The assortment of pools is expanding every year due to the fact that the owners of suburban areas and private houses increasingly want to install them in their yard. Even when planning a purchase you need to decide on a number of issues that relate to water heating, because you want to swim in the pool, not only in the summer heat.

There are many special devices that heat water to the set temperature value, for example, a pump for a heated pool. They differ in cost, energy efficiency, efficiency and the very principle of action.

The temperature level depends on the category of people swimming:

• About 26 ° C for the elderly;
• 28-32 ° C for children;
• 22 ° C for sports and active games.

Basic views

The heating of the pool to the optimum temperature is carried out by heating devices, the category of which determines the system of heating itself. It can be produced by heat exchange and an electric heater.

Devices based on heat exchange include the following categories:

• Devices with main sources in the form of a boiler, central water supply system;
• Mechanisms working on solar energy;
• Heat exchangers based on sources of other types (heat pump).

In the calculation of water heating, all the nuances of operation and the design of the selected option for the pool should be taken into account.

Electric heater

For a home pond with a small volume, the optimal system is the flow system. It is the simplest and most affordable method of heating, the main purpose is to continuously heat the flow of water with minimal pressure fluctuations.

The principle of operation is based on circulation through the housing, in which there are several heaters. It is made of high-quality plastic, titanium or stainless steel, and TENs themselves are made of reliable steel alloys that can withstand high temperatures. Due to the fact that the electric heater is installed behind the filter, clean water enters the pool.

A separate room is not required to use this type of equipment, since such heaters are compact enough and can fit in a small closed booth.

How to choose

When choosing a flow type device, you need to pay attention to several parameters:

• Materials used for manufacturing. Elements of stainless steel are the most durable.
• Presence of mechanisms for adjustment and protection, which prevent possible breakdowns. These include a flow sensor, a thermostat and others.
• Working pressure and total flow volume.
• Maximum temperature value. Basically electric heaters have indicators in the region of 30-45 degrees.
• Power. For some models, installation via a three-phase network is required.

It is important to take into account that the pools located in an unheated room or related to the open type have significant heat loss, respectively, the consumption of electricity increases. Flow-through systems may not be sufficient for a large volume of water, especially when the pond is located on the street. It is also not recommended to use a similar unit in a room with old wiring or limited power consumption.

With the help of small heaters with minimal power, children's pools, as well as frame and inflatable pools are often heated.

Advantages and disadvantages of flowing equipment

Among the positive moments of use it is worth noting the following:

• Automated control system;
• Small dimensions of the unit;
• The flow sensor responds to the lack of water and switches off the heating;
• It is possible to adjust the temperature with a thermostat;
• It takes a little time to heat the water.

There were some drawbacks, among them - a small capacity with significant financial expenses for electricity.

Innovative system of water heating in the pool

The sun is an eternal source of heat, optimally suitable for efficient heating of the reservoir both open and closed. It is believed that the heat from the solar direct rays is enough for the outdoor pool. But this statement works only when the reservoir is located on a sunny site. Thanks to the use of the solar system, the natural heating of the water in the pool at the cottage becomes regulated.

The solar heating device includes three main components: a control valve, a pump filter and a solar collector in the form of interconnected tubes on the screen. Heliosystems are based on a fairly simple mechanism of action. The sensors are triggered under intensive lighting, after which the automatic drain valve conducts the water flow from the reservoir through the heat exchanger of the collector. Heating occurs inside the heat exchanger due to the heat carrier, which circulates in a closed system.

Water starts to flow into the pool when the set temperature is reached. Circulation is not possible when the solar collector cools down in cloudy weather. This device is usually located in the lighted area or on the roof.

The solar system can consist of tubular vacuum collectors or flat highly selective. Its choice depends on the volume of water, location and climatic conditions.

The calculation of the area of the collectors should be based on several factors. It:

• Angle and location;
• The required outlet temperature;
• Type of pool (open or concealed) and its parameters;
• Water body attendance.

What you need to pay attention to

The positive aspects of using solar energy systems are as follows:

• Absence of costs for maintenance;
• Quick heating of the pool;
• Easy operation;
• Versatility - it is possible to use both for the pool and for ensuring the presence of hot water in a private house.

In this case, it is worth remembering that in cloudy weather, the heat transfer coefficient decreases. Also, significant financial investments are required to purchase and install the equipment.

Heat exchange systems

The heat exchanger makes it possible to effectively heat the pool in winter and summer, with significant cost savings, by connecting the house itself to the heating system.

The device is externally similar to a large bulb, inside which is a coil with a coolant in it. The water heats up when passing around the coil. A circulating heat pump provides water from the heating common system, to regulate its operation, a solenoid valve with thermostatic control is used. It is enough to set the desired temperature level, and all the rest will be taken up by automation.

The power of the heat exchanger is the main selection criterion, it can reach up to 200 kW. The larger the volume of the pool, the more powerful the device should be.

At the first start, the required temperature is reached only after 28 hours. Gradual prolonged heating allows avoiding an instrumental collapse, which is caused by the expansion of the liquid. In the future, the device supports the set temperature regime.

The heat exchanger should be installed after the filters and pump station, but before the disinfection system to reduce the degree of chlorine impact on the equipment. Titanium heat exchangers are recommended for use in pools with sea water and at high chlorine levels.

This equipment allows you to reduce the cost of heating the pool, while its capacity is sufficient for a large volume of water. Automated processes provide ease of management.

Energy from the environment

The heat pump is used to heat water relatively recently, the principle of its operation is based on the multi-phase heat transfer due to the compression of gas and condensate from various types of heat transfer media.

In the form of an initial source, heat of thermal, groundwater can act; Energy released during the purification of flue gases; As well as industrial (domestic) wastewater. The pump can use any sources that have a temperature higher than the available water heating level.

Through the underground pipeline, the working fluid (a mixture of water and antifreeze) is transferred. At the outlet, it is heated by several degrees due to the temperature of the ground, and passes into a heat exchanger, the coolant of which receives the incoming heat.

When the heated liquid and refrigerant come in contact, instantaneous formation of steam entering the compressor and compressing up to 25 atmospheres takes place. The compression is characterized by a sharp increase in temperature, the energy of which provides heat to the house or a heated outdoor pool in the form of a pump.

The operation of cyclic operation takes a significant amount of energy, however the capacity of this equipment is sufficient for the full heating of a large volume of water or a country house.

Advantages of heat pumps

Despite the low prevalence due to their high cost, such devices have the following advantages:

• The possibility of using free alternative heat sources ;
• High power;
• Quick heating of the pool and rooms.

Heating with liquid fuel

The fuel heater is an equipment based on the use of propane or liquid fuel. They are characterized by sufficient economy and efficiency, provided that they are used both for heating the building and for the pool.

To operate a fuel type heater, you must obtain permission to install the equipment in advance, register it and arrange all the documentation in accordance with the established rules. It is also necessary to install a chimney and a fire-fighting system, and during operation constantly monitor the fuel reserves.

Among the positive aspects of use is the automation of the system, the possibility of multifunctional use and economical consumption.

Characteristics of fuel heaters

Gas standard devices are mounted behind the pump filter through the circulation line. Such water heaters can have different capacities depending on the purpose. The system is regulated by the amount of water flowing (reducing the amount of water causes the gas supply to stop).

The gas-type units operate on propane, have a circulation pump and an integrated filter.

Devices that use liquid fuel are usually equipped with a water pump or must be connected to a circulation line.

How to improve efficiency

Any heating system will work more efficiently and much faster to heat up the Intex pool and other types of reservoirs if the possible heat losses are reduced in advance. The sunny area will be the best option for the location of the outdoor pool. It is advisable that the crown of the surrounding trees be at a distance of about five meters from the water. In this case, more heat will remain, and bathing will become more comfortable if the place is protected from the wind. At night, it is recommended to cover the outdoor pool with a special film to reduce evaporation and reduce heat loss.

The design features of the reservoir directly affect the cost of the heating system, its power and type. To install the equipment it is better to turn to professionals, they will be able to guarantee the safe and trouble-free operation of heating elements.

Inflatable Heated Pool

The inflatable pool is the fastest method of organizing a family vacation on the water. Due to the ease of installation, safety for small children and low cost, it has gained popularity all over the world. Used as the main material for the production of polyvinyl chloride rubber. It has excellent damping characteristics, resistance to moisture and ultraviolet radiation.
