Morning swimming in the pool is not the most pleasant procedure, although the temptation is great. In order for it to bring only vivacity and energy, it was not only useful, but also pleasant, it was necessary to ensure the heating of water in the pool.
A comfortable stay can be guaranteed by water heated to 23-24 degrees, and if we are talking about children, then up to 30 degrees.
How to heat pool water with an electric heater?
The simplest and most popular method does not require complex technical solutions. In this case, heating the water in the pool provides an electric heating element. Usually these are simple heating elements, for the manufacture of which an anti-corrosion alloy is used. Their main difference is in power, which varies from 3 to 18 kW.
Heated water in the pool with an electric heater is quite an expensive pleasure. It is advisable to use such a system only if a small bathing capacity is installed. Each heater is equipped with a temperature sensor, which is very easy to use and provides autonomous heating of water. The main tasks of the thermostat include turning on and off the heater, as well as maintaining the specified parameters.
Flow heater
Instantaneous water heaters can be called a fairly inexpensive and very effective way of heating water in a frame or inflatable pool. These devices are designed to heat a continuous flow, the pressure of which must be uninterrupted.
Instantaneous water heater includes:
- the case made of high-quality non-flammable plastic;
- TENY, for the production of which stainless steel of high quality is usually used, which is not afraid of either high voltage or high temperatures.
When choosing any heater, the volume of the pool for which it is installed should be taken into account. So, if the reservoir is small, then the optimal value of power is 5-7 kW.
By the way, it is not recommended to use a flow heater in the presence of a large pool, whose area is 35 square meters.
Among the main advantages of such devices can be identified:
- a short period of time for heating;
- convenient temperature control;
- automation of the heating process;
- compact sizes.
Pool boiler or stove
Quite unusual, but still real is the heating of the water in the pool with firewood. A boiler or stove is recommended to be used only if it is a compact stationary design 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 the most simple and economical option.
The installation of a gas boiler must be preceded by a permit in the appropriate authority. But if there is no such paper, and the payment for the services of a professional installer does not fit into the family budget, then a simple and effective wood stove with a coil can solve the problem.
About natural energy sources
How to heat water in the pool in the country and at the same time not to spend money on fuel? You can use solar and underground heat or wind power.
Each of the above systems is quite practical. The only drawback is the high operating costs. Regular heating of water in the frame pool significantly “hits” the family budget. Of course, you don’t have to pay for the energy received from the external environment, but for its correct conversion you will need a heater, the installation of which will require not only physical effort, but also significant costs.
Geothermal heat pump
This device is able to draw energy from the deep layer of the earth or underground reservoir. First, you need to drill the well, and then lower a special probe to its bottom, along which the coolant will be circulated. The principle of operation is quite simple: a pool water heating pump raises the heat carrier up, takes heat and directs it to the heat exchanger.
solar collector
Such technology does not involve serious financial and labor costs, but simply and quickly heats the water to the desired degree. At the same time, the solar collector is suitable both for the pool located in the fresh air, and for the indoor structure.
The heating system includes glass tubes connected by a single heat exchange circuit. The tubes heat up under the influence of hot sunlight and transfer heat to the heat exchanger, and it to the water.
Heat pump for water heating
A heat pump removes heat from an external heat source, converts it and transfers it to a heated medium. Heated water in the pool is usually carried out using devices such as "air-water" (air serves as a source of heat, and water as a consumer).
Externally, the device is similar to air conditioning. Such devices require only connection, setting the mode and the desired temperature. For control, you can use the remote control or panel located on the body.
For operation, the heat pump requires a 220 V network. Moreover, the consumption directly depends on the power of the device. The cost of the device is quite large - about 130-180 thousand rubles.
How to keep warm heated water?
How to heat the pool water in the country and save the result? After all, no matter what the heavy-duty and practical installation for heating water is used, it is impossible to achieve the desired comfort and economy without a temperature saving system. Therefore, first you need to calculate the water heating in the pool and analyze the heat loss.
To take into account all indicators, you need to pay attention to radiation, convection, conduction and evaporation of water from the surface of the pool. The most primitive method of reducing heat loss is the selection of the correct coating (bedspreads), if we are talking about an externally built-in pool. As a material, you can use a floating polymer coating or special blinds. This method saves at least 50% of the heat.
In addition, you can use a similar, but much more effective coating to maintain heat in the water - this is a transparent cover for sunlight. During cold weather, an outdoor pool must be protected with a heat-insulating coating.
Fashionable novelty or long-awaited savings?
This type of equipment is considered ideal for an outdoor pool or pond. It includes a heating distribution tank 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:
- solar energy generator;
- an inverter whose main task is the conversion of solar energy into electricity or heat;
- a system that allows you to remove the converted energy for heating water in the pool.
Also, you can not do without a tank expander, which removes hot water and distributes it in the pool.
Heating in the solar system can be carried out both in a passive way (hot water transfers heat to the cold), and due to the circulation provided by the pump unit.
The cost of a solar heater cannot be called small, but during its use you can more than make up for the amount spent, since you will not need to spend electricity or any fuel. To heat a pool of 30 m 3, a collector is required that includes at least 120 vacuum tubes or several collectors equipped with 10-12 tubes.
You can buy such an installation for about 15-15.5 thousand dollars.
Useful Tips
The easiest way to resolve the issue of how to heat water in the pool is a flow-through heater. After installing this appliance, the water not only quickly heats up, but also retains heat for a long time. After all, the process is ongoing.
If you plan to install it yourself, then you need to remember about the thermostat, as this will help to organize control and adjustment of comfortable temperature in the pool. A simple formula allows you to calculate the optimal power of the device needed to heat a certain amount of water.
Other systems, such as a heat exchanger or heat generator, require professional experience for both installation and operation. But they belong to low-cost options, so they are very popular.
An equally well-known method of heating water in the pool is the installation of solar panels 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.
