In modern conditions, the purchase of their own device for the production and supply of heat costs customers a fairly large amount. To save money or in the absence of the opportunity to purchase a heat source in the store, there are reasonable reasons to construct a heat generator with your own hands. There are several varieties of such projects. The choice depends on the technical capabilities of the owner or the tasks that need to be solved with the help of a heat-generating system.
The benefits of homemade heat production
In general, there are two types of devices: static and rotary. If in the first embodiment there is a nozzle at the base of the design, then other machines create cavitation using a rotor. These vortex structures can be compared with each other and choose the appropriate option for assembly.
A self-constructed heat generator will help provide a comfortable temperature regime for a country house, cottage, separate cottage, apartment - in the absence of centralized heating, its defects, interruptions or accidents.
Also, such devices help offset the cost of heat, choose the best option for energy supply. They are simple in terms of design and economical, environmentally friendly.
How to make a heat generator with your own hands?
The assembly will require the following materials and tools:
- a sufficient number of pipes corresponding to the room along the length and width;
- a puncher (drill) for drilling pipes;
- pump;
- cavitator of any kind;
- pressure gauge;
- a thermometer for measuring the level of heat and a sleeve for it;
- taps for heating systems;
- an electric motor.
For different types of systems, additional components may be required. But in general, home-made heating appliances are quite accessible for everyone to design and configure.
Cavitation construction
Do-it-yourself cavitation heat generator can be made on the basis of a centrifugal pump, which is often available in the bathroom, well, cottage water supply system. The low efficiency of such a pump can be converted into energy from a cavitation heater. The transition of mechanical energy to heat. This principle is often used in industry.
Cavitation heat generator with its own hands is made on the basis of a pump that pumps pressure above the nozzle. The disadvantage of a cavitacin device is a high noise level, high power, inappropriate in small rooms, rare materials, dimensions - even a miniature model will occupy 1.5 square meters.
Wood heating
A self-made wood-burning heat generator will provide stable heating of rooms in the absence of centralized heating and the presence of a sufficient amount of wood fuel. No matter how technologies and construction methods develop, a wood stove, a fireplace will be saved during interruptions in the heat supply.
For heating on wood, a fireplace or a traditional stove is installed .
But such systems require careful adherence to safety standards. It is important to determine the installation location of the furnace - massive units can not always be placed in country houses.
Making a wood-based heat generator with your own hands is a good solution if you need independent heating of the rooms. Sometimes this is really the only option for heating.
Potapov device
Do-it-yourself Potapov heat generator can be made using the following materials:
- grinder for corners;
- welding device;
- drill and drill;
- ring keys on 12 and 13;
- various bolts, nuts, washers;
- metal corners;
- paints and primers.
A self-made Potapov heat generator allows you to generate heat on the basis of an electric motor using a pump. This is a very economical option, which is quite simple to make from ordinary parts.
The engine is selected depending on the existing voltage - 220 or 380 V.
With it, the assembly begins, fixing on the bed. A metal frame is made of a square, welding and bolts, nuts help to fix the entire structure. Holes for bolts are made, the engine is placed inside, the frame is covered with paint. Then, a centrifugal pump is selected, which will be untwisted by the engine. The pump is mounted on a frame, however, in this case, a coupling from a lathe will be required, which can be ordered at the factory. It is important to insulate the generator with a special casing of tin sheets or aluminum.
Frenett generator
Many fans of technical experiments do the Frenetta heat generator with their own hands - this unit is known for its incredibly high efficiency and a wide variety of models. However, many of these heat pumps are quite expensive.
Do-it-yourself Fresnett heat generator can be made from the following components:
- rotor;
- stator;
- paddle fan;
- shaft, etc.
The stator and rotor act as cylinders, one inside the other. Oil is poured into a large one; a small cylinder heats the entire system due to its revolutions. The fan provides hot air. This is a fairly simple model of the heat pump, which can be improved. In the future, you can replace the inner cylinder with steel discs or remove the fan.
A high level of efficiency is ensured by the circulation of the heat carrier (oil) in a closed system. There is no heat exchanger, but the heating power is quite high. This system saves costs, which usually need to be allocated to other types of heating.
Magnet generator
Magnetic heating systems are of the vortex type and operate on the basis of an induction heater. In the process of functioning, an electromagnetic field is formed, whose energy the heated objects absorb and convert into heat. The basis of such an aggregate is an induction coil - a multi-turn cylindrical coil, when passing through it an electric current creates an alternating state magnetic field.
Do-it-yourself magnetic heat generator is made of elements: nozzle and pressure gauge at the outlet, thermometer with sleeves, taps and induction elements. If you place a heated object near such an aggregate, the generated magnetic flux will permeate the heated object. The electric field lines are perpendicular to the direction of the magnetic particles and go in a closed circle.
In the process of divergence of the eddy currents of electricity, energy is transformed into heat - the object is heated.
A self-made magnetic heat generator (with an inverter) allows you to use the strength of magnetic fields to start the pump, quickly warm the room and any substances to high temperatures. Such heaters can not only heat water to the desired temperature, but also melt metals.
Diesel generator
A self- assembled diesel heat generator will help to solve the problem of heating indirectly. The entire heating process in such units is fully automated, the diesel device can be used in spray booths and industrial needs.
The main type of fuel in this case is diesel or kerosene. The device is a gun, which is formed from a body (casing), a fuel tank and an attached pump, as well as a cleaning filter and a combustion chamber. A fuel tank is placed at the bottom of the unit for convenient supply of a resource.
A self-made diesel heat generator will help to efficiently and quickly heat the room in a rather economical way.
Also
diesel fuel can serve as
fuel. Diesel units have a nozzle that atomizes the fuel as it burns out, but in some cases it can be supplied by the drip method. When counting on continuous operation, it is necessary to refuel the generator twice a day.
Design test
A self-made heat generator will work as efficiently as possible if you conduct preliminary tests of the entire system and correct possible defects:
- All surfaces must be protected with paint;
- the body must be made of thick material due to very aggressive cavitation processes;
- the inlets must be of different sizes - this way it will be possible to regulate the performance;
- The vibration damper must be changed regularly.
It is better to have a special laboratory area where generator tests will be held.
The best option - in which the water heats up more strongly for the same lengths of time, this device can be preferred and further improved.
Owner reviews
To date, a large number of home owners have already completed the development of their own units.
If you make a heat generator with your own hands, then, according to most craftsmen, you can really get an economical option for heating a room. You can literally make these units from improvised materials, which allows everyone to get their own heat source. Some models require factory parts that can be made to order in an industrial environment.
