Pouring cold water over and occasionally diving into an ice-hole in some cases can be beneficial for health. But for a long time in such conditions can not swim. To fully enjoy the comfort of bathing, it's good to know how to make a water heater for the pool with your own hands. Not in all places weather conditions are such that the fluid can warm up just by being in the sun. It is in these situations that we cannot do without additional help.
On the wood
Water is the medium in where the human body relaxes and rests in the best possible way. But, in addition, it is in such conditions that there is a danger of injury that could be injured. For this reason, the heating system must meet the basic requirements:
In most cases, it does not work out that a specific mechanism meets all the points listed, but if at least 80% of them are covered, then this solution can be considered very productive.
Spiral water heater
The ideal solution is which does not consume any coolant and electrical energy. But in real conditions this is almost impossible to achieve. There are a large number of varieties of both commercial and independent developments.
Use of a gas boiler . This option can not be called economical, but thanks to him a large amount of heat can be quite quickly. The disadvantage of such a system is the need for some refinement. If you put water from the pool directly into the heater, it can clog it and lead to the formation of scale on the heat exchanger. In turn, this will result in costly repairs.
Wood-burning . This makes a small firebox through which the coil is passed. Water, passing through it, heats up and returns to the tank. In this case, you must constantly monitor the state of the system and do the loading of firewood. Also there is no possibility to carry out continuous heating. At night, the water will lose its temperature.
Heat pumps . It makes no sense to put such a unit only to heat the pool. It will be inexpedient in terms of performance and material waste. You can use it in the case when it is already built into the heating system of the whole house. The condition for its operation is the ambient temperature, which must be above + 5 ° C.
The principle of operation of the heat pump
of the heat pump . Inherently similar to instantaneous water heaters for domestic use. The principle of operation is that the fluid passes through the coil, which is in contact with the heating element. Thus, the transfer of thermal energy. Such a solution is very uneconomical in terms of energy costs. The power elements can reach and exceed 6 kW. If you apply it for a long time, then the electricity bill will block all the joy of bathing.
Electric water heater
Solar water heaters . In such decisions, the sun acts as a heater. His resource is inexhaustible, you do not need to pay for it, so this solution can be considered ideal. But do not forget that during high clouds, when the rays are scattered, the performance drops, and at night it is completely zero.
Homemade solar collector
You can install or connect to any of these options yourself. Some can be assembled with the first screw. How to do this will be discussed below.
Heating the fluid in the pool is only half the battle. Constantly it is necessary to monitor the cleanliness of the internal space, and also to ensure that the water does not bloom. Heat preservation is also one of the main tasks.
To make a productive and interesting version you need the following components:
The manufacturing sequence will be as follows:
Two layers of polycarbonate
Pipe sections with fittings and hoses
The nozzle is fixed, slots are made
Polycarbonate water heater
The essence of the operation is that cold water taken from the bottom of the pool, served in the lower part of the polycarbonate. Passing through its entire area through small channels, it warms up and returns again to the tank. With a reservoir size of 6 * 2 m, the power reaches approximately 7 kW.
Another heating mechanism is also quite simple. You will need:
The assembly of the whole structure is carried out as follows:
Water, passing through the coiled sections of the pipe, manages to warm up well and subsequently release its temperature of the liquid that is in the tank. The coils may not necessarily be arranged as described above. You can make the construction of large sizes and lay the pipe snake or other pattern, which will ensure maximum heating.
To automate the entire process, the pump can be connected to a special timer.On the device to make settings in this mode, so that it starts functioning only during the day. The supercharger will turn on independently and you will not have to worry about uncomfortable conditions.
The essence of the method, which will be described below, fundamentally resembles solar heaters. Only the main element is not a natural, but an artificial source. Consider the general scheme. Components can be easily replaced by those that are available in a particular case. You will need:
Before starting the assembly, you need to find a place in the area where you can freely make a fire. It should not be too close to the pool, because it can damage it if it is assembled from PVC film or wood.
Radiator of water heating
If desired, a pool with 11 thousand liters of water can be heated to a temperature of 27 ° C in one day. If you continue to warm up, then you get an impromptu Jacuzzi.
Before using an old battery or radiator, be sure to rinse them well. In the middle there can be a raid and rust, which will lead to damage to the impeller of the pump, and also stain water.
You can make a portable device that will be used on a permanent basis. To do this, you need a metal pipe with a diameter of 200 mm. Its height should be 80‒100 cm. A square sheet of metal measuring 30 * 30 cm is welded to the bottom. A copper tube of the desired diameter is screwed on the outside. The upper end is connected to the hose, through which water enters the pool, to the lower end - the flow. In order for the entire system to work, it is necessary to make a fire inside the cartridge and constantly place firewood. Water, rising on a snake, will warm up and then give up its temperature in a common tank. To increase the efficiency of the installation, you can find another sleeve of larger diameter and install it as a casing, then the heating will be carried out even faster.
As mentioned above, connecting directly to the boiler is fraught with costly repairs. Special heat exchangers have been developed for this case. They represent a small flask that is connected through a manifold to the heating system. In it on a snake hot water circulates. Thanks to the pump, which is installed near the pool, liquid from it is fed into this sleeve, where the exchange takes place.
The article can be used as a practical guide for assembling a specific heater or as a hint for your own designs . We are sure that you will be able to assemble a productive unit.
