What is the heater for the pool
For heating water in the pool, boilers on wood or other solid fuel can be used.
This method is effective and economical. the average efficiency of a solid fuel boiler is about 70%, and the cost of firewood is the lowest compared to other types of fuel.
Firewood for heating water is better to use dry and finely chopped. However, not only firewood is suitable for such a boiler, you can burn fuel on the basis of TOA, coal, as well as various combustible garbage, which periodically accumulates on a private site.
How to heat a lot of water for the pool
In practice, water heating in the pool is carried out by different methods:
-
With the help of a flow method. To heat a large amount of water, its circulation is organized through the heating device. The liquid is taken from the bottom of the pool, filtered and passed through the heater. Warm water under pressure is injected down the pool from the opposite side of the fence hole.
In different cases, electricity, the energy of the sun, the burning of gas, oil products and wood stoves helps to heat the pool in different cases.
Types of water heaters
Spiral water heater
An ideal option is a solution in which no coolants and electric energy are consumed. But in real conditions this is almost impossible to achieve. There are a large number of varieties of both commercial and independent developments.
Using a gas boiler. This option cannot be called economical, but thanks to it, a large volume can be heated quickly enough. The disadvantage of such a system is the need for a certain refinement. If you let water from the pool directly into the heating device, this can clog it and lead to the formation of scale on the heat exchanger. In turn, this will result in expensive repairs.

Wood
Drovyanaya water heater. In this case, a small firebox is made through which the coil is passed. Water passing through it heats up and returns back to the container. In this case, it is necessary to constantly monitor the state of the system and load firewood. There is also no way to carry out continuous heating. At night, water will lose its temperature.
Heat pump
Thermal pumps. It makes no sense to put such an unit only for heating the pool. This will be inappropriate in terms of performance and material embezzlement. You can use it when it is already built into the heating system of the whole house. The condition of its functioning is the ambient temperature, which should be above 5 ° C.
The principle of operation of the thermal pump
Electric heaters. In essence, they look like running water heaters for household use. The principle of operation is that the fluid passes along the coil, which is in contact with the heater. Thus, thermal energy is transmitted. This solution is very uneconomical in terms of energy consumption. The power of elements can reach and exceed 6 kW. If you use it for a long time, then the expense for electricity will block all the joy of bathing.
Electric water heater
Solar water heaters. In such decisions, the sun acts as a heater. Its resource is inexhaustible, you do not need to pay for it, so such a solution can be considered ideal. But do not forget that during high clouds, when the rays are scattered, performance falls, and at night it is completely zero.
The solar collector is homemade

Installation or connection to any of the listed options can be carried out independently. Some can be assembled from the first screw. About how to do this will be further.
Fluid heating in the pool is only half the case. It is constantly necessary to monitor the purity of the internal space, and then so that the water does not bloom. Conducting heat is also one of the main tasks.
Popular models
The assortment of the models of wood furnaces is very diverse. Today, many companies that are engaged in the manufacture of frame pools also produce heaters for them. The most famous manufacturers of pools for pools are:
Most often, the consumer buys Buderus products. This is a German brand that has been manufacturing heating devices for many years. As for the wood boilers for heating water in the pool, I would like to note the following models: S111–32D, S111–45D, S171–22W, S17–50W.
Fans of swimming even in the cold: a wood.like pool oven. How to build yourself?
Fans of accepting water procedures in the cold season involuntarily have to choose reservoirs with cool or completely icy water.
But not everyone can withstand bathing in an ice hole or an unheated font with a temperature of 12-15 degrees.
Therefore, the task arises to heat the water. Of course, to heat the whole lake or the river will not be able to. But a bath font or a small pool will not heat difficulties.

Wood burning stove
Fuel stoves can cope with any volume of heated water in the pool, they are easy to operate and economical.
You can choose the right stove for heating the pool by determining the task that is facing the equipment:
- Heating of year.round pools with a large volume of water, maintaining a constant temperature. Massive brick furnaces with a heat exchanger, prolonged combustion boilers of the strip type, pyrolysis boilers with mine structure are perfect for solving this problem.
The advantages of such furnaces are the ability to maintain the same temperature in the heat exchanger for a long time and adjust the heating rate, a large battery life without loading, the ability to heat the pool using indirect heating. Minus. relative high cost of equipment, complex plumbing strapping.
- Rapid heating of the seasonal indoor pool and maintaining the required temperature. The main requirement for equipment is high power. It can be calculated by knowing the volume of the pool, the difference in water temperature, heat loss. To heat 1 liter of water by one degree in 1 hour, you need 0.001 kW. Heating 1 thousand. liters in 1 hour will require a power of 1 kW.
Given the heat loss, you need to multiply this indicator by 1.2-1.3. Thus, the boiler for 25 kW will heat 1 cubic meter for 1 degree in 15-20 minutes. The water heater must be arranged stationary, it is better to use a flow heating scheme.
- Rapid heating of a small street pool at low ambient temperature. The main requirement for a boiler for this mode of operation is high power and mobility. Small weight and compactness of the furnace will be a pleasant addition.
The optimal choice of material for the heater
To choose the right material for the heater for the pool, you need to take into account the following factors:
The possibility of transportation. The brick device due to large weight is better to have stationary, on a good foundation.

If the pool is collapsible and mounted in different places, then it is better to use the metal structure.
Brick boiler is durable and looks good. A brick furnace can also perform a number of other functions: heat the room, cook food. In the presence of skills, such a device can be made independently, which will significantly reduce the cost of the entire heating system.
Homemade metal structure is chosen if the budget is limited.
The boiler scheme
Various types of structures are used to heat water in the pool. Devices consist of a furnace, heat exchanger, case and chimney.
Metal units are mobile, have a large efficiency, do not require a thorough foundation.
The simplest home.made device for heating water in the pool is a metal cylinder, inside of which a heat exchanger is laid along the walls: a stainless steel coil of a coil. Firewoods are burned inside, water is supplied with a pump or flows into the pool located nearby.
For the manufacture of a pool heater, a similar coil is necessary: this is a heat exchanger by which the coolant will circulate.
It is more difficult to make a metal bourgeois with a built.in heat exchanger, but it is more effective. The firebox is located under a heat exchanger, in the role of which a grid of cooked pipes, a coil, ribs of cast.iron batteries, car radiators with sparse records can act. Hot gases passing through the heat exchanger warm the circulating liquid.
In the boilers based on a prolonged burning stove “Bulerian” all fuel goes to heating passing water. Homemade craftsmen have long learned how to make such devices from profile pipes and sheet metal.
DIY boiler building
When working with metal, it is important to observe the simplest safety rules.
Choosing a project
For a home master, a real challenge will be an independent manufacture of a “Buleryan” type heater, however, in the presence of patience and metal welding skills, this task is an execution.
To create a device for heating water, you will need a square profile pipe with a wall thickness of 4 mm. During operation, a welding machine, a corner grinder, clamps and other locksmithing devices are used.
In addition to a square pipe, you will need several sheets of iron for the second chamber and doors, a valve, a pipe for an expansion tank, plumbing threads for the output and input of the coolant.
Welding of a hot water stove on firewood
First of all, collectors are welded: lower and upper. The lower one has the form of a “box”, the whole structure will stand on it, the upper one will be of an arbitrary shape, and performs the function of an expansion tank.
The heat exchanger consists of M-shaped square or curved in the form of a clamp of round pipes. Their bottom is connected to the collector, the top. with an expansion tank. The gaps between the pipes are brewed tightly with sheet metal.
The heights of the resulting tunnel are installed at 2-3 of the secondary cash camera. Hot gases rise along a hot shelf. It is better to make it from metal 5-7 mm thick, and the ducts are brought up by the beginning of the shelf.
Heating with a heat exchanger
If a winter pool is installed or with a large reservoir, then heating is mounted based on the heat exchanger. It is connected directly to the heating system of a house, for example from a gas boiler. Made in the form of a coil in a flask, according to which hot water flows.
The coolant moves due to the circulation pump. The liquid enters the flask, where it warms up from the coil. With each new circle, it heats up more and more. After returning to the bowl. The process is automatic, does not require special control. The user only sets the temperature on the thermostat.
The heater is selected based on the dimensions of the pool. On the first day they are included in maximum power, then maintain the optimum temperature. At the same time, sharp differences cannot be allowed.
We offer to familiarize yourself: what to do if the water in the bath is constantly freezing?
WOOD BURNING POOL HEATER HOMEMADE
The heat exchanger is installed between the pump and the disinfection system. Chlorine will not fall into the apparatus, which will increase its service life
This is how one of the heat exchangers for the pool is a metal cylinder, according to which hot water flows. It is connected to a hot water source. Often it is a heating circuit of hot water of the boiler or a flowing water heater. There may be other sources. Who to adapt.
Here the question immediately arises: why is the heat exchanger itself? After all, you can take water directly from the pool, serve to the heater and heated. In principle, such a scheme is possible, but the problem is that the water in the pool contains many different impurities: from chlorine and chemistry, to different tiny suspended particles. So with such a scheme, the heat exchanger will quickly clog.
Another point-in the reservoir in non-open air, a fairly large amount of oxygen is contained, due to which the heat exchanger in the boiler or a fuel heater will quickly oxidize and fails and fails. That is why a loop with a special heat exchanger for the pool and drive a small volume of coolant.
One of the types of heat exchangers is the coil. It can be made independently, and also connected with your own hands to the system. For those who made heating in the house, this is not a problem. But coils are effective only on small volumes. They will warm the small pool for children in a small interval, and with a dozen cubes, they will not cope for sure.
Water heating scheme in the pool
The power of the spiral.
For heating water in the pool, a large amount of thermal energy is required. Among the possible methods of heating, we offer the most economical and effective. heating the pool with wood. The power of water heaters varies from 18 to 55 kW, this depends on the number of turns. To heat water in a small pool, you will have enough BASIS 18 kW heater. For owners of the pools of impressive sizes, a volcano 50 capacity of 55 kW will be required.
Heating the pool with wood is the most economical way of heating water, because the consumption of dry birch wood for the most powerful Volcano 50 model is only 20 kg/hour. Efficiency = 70% all water heaters undergo testing for tightness with pressure of 15 atm. Electric welding pipes are torn with a load of 170 atmospheres.

We personally measured the power of our heater for the pools, and we can guarantee this result, the above capacities can increase or decrease, it all depends on the intensity of combustion, rock and moisture content, we give average stable indicators when the firebox is birch logs.
Look
Black steel spirals are subject to corrosion and aggressive environments, so their service life is much less than in a stainless steel spiral and is an average of 5-7 years.
