Heating of water in the pool: heating devices and characteristics

Morning bathing in the pool is not the most pleasant procedure, although the temptation is great. In order to bring only cheerfulness and energy, it was not only useful, but also pleasant, it is necessary to provide heating of water in the pool.

A comfortable stay can guarantee water heated to 23-24 degrees, and if it comes to children, then up to 30 degrees.

How to heat the water in the pool with an electric heater?

The simplest and most popular method does not require complicated technical solutions. In this case, the heating of the water in the pool is ensured by an electric heating element. Usually these are simple heaters, for the production of which an anticorrosive alloy is used. Their main difference is in power, which varies from 3 to 18 kW.

Heating the water in the pool with an electric heater is quite expensive. It is advisable to use this system only if a small bathtub is installed. Each heater is equipped with a temperature sensor, which is very simple to handle and provides autonomous heating of water. The main tasks of the thermostat include switching on and off the heater, as well as maintaining the set parameters.

Instantaneous Heater

Flowing water heaters can be called quite inexpensive and very effective way of heating water in a wireframe or inflatable pool. These devices are designed to heat a continuous flow, the pressure of which must be uninterrupted.

The instantaneous water heater includes:

• A body made of high-quality non-flammable plastic;
• TENs, which usually use high-grade stainless steel, which is not afraid of either high voltage or high temperatures.

When choosing any heater, consider the volume of the pool for which it is installed. So, if the pond is small, then the optimum power value is 5-7 kW.

By the way, a flow heater is not recommended for use in the presence of a large swimming pool, the area of which is 35 square meters.

Among the main advantages of such devices are:

• Small time for heating;
• Convenient temperature adjustment;
• Automation of the heating process;
• Compact size.

Boiler or pool oven

Quite unusual, but still realistic is the heating of water in the pool by firewood. A boiler or oven is recommended to be used only if it is a compact stationary structure or a summer bath for 1-2 people. For the operation of such a system, gas or diesel fuel is also suitable, but firewood is considered to be the simplest and most economical option.

Installation of a gas boiler must necessarily be preceded by obtaining a permit in the appropriate authority. But if there is no such paper, and payment for the services of a professional installer does not fit into the family budget, then a simple and efficient wood-burning stove with a coil can solve the problem.

About natural energy sources

How to warm up the water in the pool in the country and do not spend money on fuel? You can use the sun and underground heat or wind energy.

Each of the above system is quite practical. The only drawback is high operating costs. Regular water heating in the frame pool significantly "beats" on the family budget. Of course, there is no need to pay for energy received from the external environment, but for its correct conversion it will take a heater, the installation of which will require not only physical efforts, but also significant expenses.

Geothermal heat pump

This device is able to draw energy from a deep layer of the earth or an underground reservoir. First, you need to drill a well, and then lower it to its bottom with a special probe that will circulate the coolant. The principle of operation is quite simple: the pool heating pump lifts the coolant upwards, takes heat and directs it to the heat exchanger.

solar collector

This technology does not involve serious financial and labor costs, but simply and quickly heats the water to the desired degree. In this case, the solar collector is suitable for both a pool located in the open air and a covered structure.

The structure of the heating system includes glass tubes, connected by a single heat exchange circuit. The tubes are heated under the influence of hot sunlight and transfer heat to the heat exchanger, and it - into the water.

Heat pump for water heating

The heat pump takes heat from an external heat source, converts it and transfers it to a heated environment. Heating of water in the pool is usually carried out with the help of devices such as "air-to-water" (air serves as a source of heat, and water for consumers).

Externally, the device is similar to air conditioning. Such devices require only connection, setting mode and the desired temperature. For control, you can use a remote control or a panel located on the body.

For operation, the heat pump requires a 220 V network. At the same time, the consumption directly depends on the power of the device. The cost of the device is quite high - about 130-180 thousand rubles.

How to keep warm warm water?

How to warm up the water in the pool at the cottage and save the result? After all, whichever super-powerful and practical installation for heating water is used, without the presence of a system of saving the temperature, it is impossible to achieve the desired comfort and economy. Therefore, it is first necessary to calculate the heating of water in the basin and analyze the heat losses.

In order to take into account all the indicators, attention must be paid to radiation, convection, conduction and evaporation of water from the surface of the basin. The most primitive method of reducing heat loss is selecting the right coating (coverlet), if it is an outdoor pool. The material can be a floating polymer coating or special blinds. This method saves at least 50% heat.

In addition, you can use a similar, but much more effective coating to keep the heat in the water - it's a transparent cover for the sun's rays. During a cold time, an outdoor pool should be protected by a thermal insulation coating.

Fashionable novelty or long-awaited savings?

This type of equipment is ideal for an outdoor pool or pond. Includes a tank for heat distribution and a solar collector. The latter should be installed on the southern open surface or on the roof of the house.

The collector consists of:

• A generator of solar energy;
• Inverter, the main task of which is the conversion of solar energy into electricity or heat;
• A system that allows to derive the converted energy for heating the water in the basin.

Also you can not do without a tank-expander, which takes out hot water and distributes it in the pool.

Heating in the solar system can be made both in a passive way (hot water transmits cold heat), and due to the circulation provided by the pump unit.

The cost of a solar heater can not be called small, but during its use, you can more than make up the amount spent, since you will not need to spend electricity or any fuel. To heat the pool in 30 m ^3, a collector is required, including at least 120 vacuum tubes or several collectors equipped with 10-12 tubes.

Buy this installation can be about 15-15.5 thousand dollars.

Helpful Tips

The simplest way to solve the problem of how to heat water in the pool is a flowing electric heater. After installing this device, water not only heats up quickly, but also retains heat for a long time. After all, the process is carried out continuously.

If you plan to install yourself, you need to remember the thermostat, as this will help to organize the control and regulation of the comfort temperature in the pool. A simple formula makes it possible to calculate the optimum power of the device necessary to heat a certain volume of water.

Other systems, such as a heat exchanger or a heat generator, require professional experience for both installation and operation of the devices. But they are low-cost options, so they are very popular.

Equally well-known method of water heating in the pool is the installation of solar batteries equipped with one-, two- and three-way valves. Currently, this option can be called the most economical and safe.

In this matter, the abundance of options does not complicate the choice, but allows you to classify and systematize it.
