This problem should be solved at the project development stage. But if this was not done, there are quite a few different schemes and the corresponding equipment with which you can organize heating the water in the already built pool. Consider the features of installing different types of kits with your own hands, and what exactly to stop the selection, the reader will be able to decide for himself.
Note! It is not meaningful to develop an independent design of the equipment for two reasons. Firstly, any mistake in the calculations is fraught with big problems, so making everything from scratch requires special knowledge. Secondly, there is everything necessary for heating water, and it is difficult to name the price of a simple solar collector( for example, from 13,000 rubles).
Overview of technical devices for heating water in the pool
Heat pump
Approximate cost of such a device, sufficient for a pool of 50 "cubes" - about 100 000 rubles.
The principle of its operation is shown in the diagram:
Pros:
- Installation and maintenance do not require the involvement of specialists.
- Efficiency - high.
- En / consumption - the minimum.
- Compactness of equipment.
- Fast heating of liquid.
- Reliability.
Cons:
- Installation only in a spacious room, as it requires a high-quality blow-out of the pump.
- The high price of the device.
Heater / heater
Flow type device. Equipment for the pool for 45 - 50 m³ costs approximately 21,890 rubles.
The heating element of most devices is a heater, although spiral devices are used in some models.
Pros:
- Installation can be made by any scheme. If additional system elements are purchased, the heating process can be automated.
- Low heater cost.
Cons:
- Longevity largely depends on the quality of the water( it is recommended to install a filter for the pool).
- The complexity of the connection. In order not to overload the line, such devices are "carried" through the phases. Therefore, it is necessary to provide power 220 / 3f.
- Consumes a lot of l / energy, so operation( considering the current tariffs) is quite expensive.
- In terms of safety engineering requires increased attention.
Collectors
Flat
The cost of a panel for a pool of 30 m³ is about 22,000 rubles( its area is 5 m², without support).
Pros:
- Mounting is possible on any basis.
- Care is almost not required.
Cons:
- Heat loss is significant.
- Repair is complex and expensive.
- Complete dependence on weather( natural light).
Vacuum
The price of the kit can vary in the range of 13 600 - 215 000 rubles. It depends on the number of tubes( the cost of one - about 890 rubles).
These models of collectors are considered more convenient to operate.
Pros:
- Heat losses are negligible.
- Inertness in relation to changes in ambient air temperature.
- Possibility of self-repair.
- Efficiency - high. Heating water is provided even in cloudy weather, as the elements react to the IF radiation.
Cons:
- Installation is made at a certain angle( not less than 18 - 200).
- Need for regular cleaning of the panel( eg from snow).
- The complexity of installing the system.
- The device, with all the same parameters, costs more than a flat analog.
Heat exchanger
These devices are the class of water-flow type water heaters. The cost starts from 11 000 rubles.
For their operation, a heat generator is required which ensures the supply and circulation( by means of a pump) of hot water in the 1st circuit. This can be a boiler included in the heating system of the building, or a separate source of thermal energy, which operates only on the pool heat exchanger.
Pros:
- Small overall dimensions.
- Easy installation and maintenance.
Cons:
- Inertia. Heating the water to the required temperature is quite long.
- The price of the pool heating equipment, given the volume of the tank, is quite high. For 50 m³ it reaches 45 000 rubles.
- An external( working) heat source in the form of a boiler or another is needed. This increases the cost of operating the system, as in summer the heat generator will have to "drive" almost empty, only to ensure the heating of the pool.
What to take into account when choosing equipment for water heating
- Water in an open water body cools faster than in a closed one. Therefore, for all equal parameters, in the first case, the capacity of the equipment should be greater.
- It is believed that the water temperature in the range of +24( ± 1) ºС for bathing is the most comfortable.
