How to install an induction boiler?

Despite the huge num­ber of ways to obtain heat using nat­ur­al resources, home­own­ers are increas­ing­ly turn­ing to the use of elec­tric heat­ing instal­la­tions to heat their homes.

Elec­tric­i­ty boil­ers are envi­ron­men­tal­ly friend­lysince no com­bus­tion prod­ucts are emit­ted into the atmos­phere, which appear dur­ing the com­bus­tion of oil prod­ucts, gas, coal and even fire­wood.

Anoth­er plus use of elec­tric heat­ing is the ease of main­te­nance of heat­ing sys­temsmount­ed on the basis of elec­tric boil­ers. How­ev­er, the con­ve­nience of using elec­tric­i­ty for home heat­ing is becom­ing an increas­ing­ly cost­ly way to get heat in the house — pay­ing the bill for elec­tric­i­ty con­sump­tion with each heat­ing sea­son becomes unbear­able for many.

Home­own­ers are begin­ning to look for an alter­na­tive to elec­tric boil­ers, the basis of which is a stan­dard heat­ing ele­ment.

Induc­tion elec­tric boil­ers are grad­u­al­ly gain­ing pop­u­lar­i­ty, also con­vert­ing elec­tric­i­ty into heat need­ed for space heat­ing. How­ev­er their design makes it pos­si­ble to use the ener­gy car­ri­er much more eco­nom­i­cal­lywhich sig­nif­i­cant­ly reduces the cur­rent costs of main­tain­ing the house dur­ing the heat­ing sea­son.

Ener­gy sav­ings are due to the rapid heat­ing of the heat car­ri­er of the heat­ing sys­tem. This is due to the induc­tion device, which replaced the tra­di­tion­al heat­ing ele­ment in the boil­er.

In addi­tion to reduc­ing heat­ing costs, these boil­ers have a sol­id num­ber of advan­tages over oth­er elec­tric boil­ers — high effi­cien­cy, long ser­vice life (at least 25 years) and no scale.

The internal structure of the induction heater and the principle of its operation

Winding and water heatingThe design of such a device designed to pro­duce heat ener­gy is sim­i­lar in its sim­plest form to a trans­former. Like the trans­former the induc­tion gen­er­a­tor con­sists of short-cir­cuit­ed wind­ings — pri­ma­ry and sec­ondary.

Pri­ma­ry wind­ing serves to con­vert elec­tric­i­ty into eddy cur­rents that cre­ate an elec­tro­mag­net­ic field direct­ed to the sec­ondary wind­ing. Sec­ondary wind­ing at the same time it is both the body of the induc­tor and the heat­ing ele­ment that trans­fers the received ener­gy to the heat­ing sys­tem. The coolant can be any elec­tri­cal­ly con­duc­tive liq­uid, rang­ing from ordi­nary tech­ni­cal water to oil and antifreeze.

Since a vor­tex induc­tion heater (or sim­ply wine) does not emit fuel decom­po­si­tion prod­ucts dur­ing oper­a­tion, it is the safest among var­i­ous types of heat­ing equip­ment used to pro­vide heat to build­ings for var­i­ous pur­pos­es. Such a heat­ing sys­tem guar­an­tees a favor­able com­po­si­tion of the atmos­phere, which means main­tain­ing its envi­ron­men­tal clean­li­ness.



Heat­ing sys­tem starts work­ing imme­di­ate­ly after apply­ing volt­age to the inter­nal wind­ing. The result­ing elec­tro­mag­net­ic field directs eddy cur­rents to the sur­face of the core locat­ed out­side.

Their den­si­ty almost instant­ly increas­es, heat­ing the sur­face of the core, and then the entire ele­ment. This heat serves to heat the coolant cir­cu­lat­ing in the boil­er.

It should be borne in mind that the device crash­es into the heat­ing sys­tem using two noz­zles. The low­er one serves to sup­ply the cooled coolant. It is mount­ed at the entrance to the boil­er, and through the sec­ond pipe the heat­ed coolant is sent to the heat­ing sys­tem.

The sup­ply of heat­ed coolant is car­ried out due to hydro­sta­t­ic pres­sure. Since the coolant con­stant­ly cir­cu­lates in the sys­tem, car­ry­ing out the removal of hot liq­uid into the heat­ing sys­tem, then the pos­si­bil­i­ty of over­heat­ing of the equip­ment is com­plete­ly exclud­ed.

Features of the installation of the boiler plant and its operation

Wiring diagramTo ensure con­tin­u­ous cir­cu­la­tion of the coolant, the heat­ing sys­tem equipped with an induc­tion elec­tric boil­er must be closed, with­out fail equipped with a cir­cu­la­tion pump. There are some rules for installing an induc­tion boil­er indoors.

The boil­er must be mount­ed at a dis­tance of at least 30 cm from the wall sur­faces. From the floor and from the ceil­ing, the dis­tance should be more than 80 cm. In order to be able to mon­i­tor the oper­a­tion of the sys­tem and ensure its safe­ty, a pres­sure gauge, a blast valve, and an auto­mat­ic device designed to remove air should be installed imme­di­ate­ly behind the coolant out­let pipe.

Before start­ing work, be sure to check the pres­ence of coolant in the sys­tem. The sup­ply of elec­tric­i­ty in its absence guar­an­tees the fail­ure of the equip­ment. You can install such a boil­er in any room of the build­ing, tak­ing into account its instal­la­tion at the above dis­tance from its walls, ceil­ing and floor.

Many con­sumers who used plas­tic pipes when installing the sys­tem are con­cerned about the ques­tion: Can an inno­v­a­tive boil­er be con­nect­ed to them? Such a prob­lem does not exist, plas­tic pipes for heat­ing sys­tems are designed for the use of any heat­ing equip­ment.

Induction boiler price and installation cost

The choice of the pow­er of the induc­tion boil­er, as well as any heat­ing equip­ment. deter­mined by the size of the heat­ed area of ​​the build­ing. The cost of the equip­ment also depends on the pow­er. The most inex­pen­sive VIN boil­er avail­able for sale costs about 300 $. The cost of instal­la­tion starts from 60 $.

The pow­er of such a heater is 6 kW, which is quite enough to heat a small coun­try house. It has two heat­ing sec­tions, 3 kW each, which is very con­ve­nient when the out­side air tem­per­a­ture ris­es. This design of heat­ing equip­ment can sig­nif­i­cant­ly reduce the con­sump­tion of elec­tric­i­ty for heat­ing the house.

Review:

For a long time I chose the VIN boil­er and bought a SAV. At 5 kW. Since there was a task to heat the coun­try house. The device does its job well. The only neg­a­tive is that the machine often knocks out and refus­es to work through the RCD. I will build a more pow­er­ful pow­er sup­ply line. Per­haps this will solve the prob­lem.

Do-it-yourself induction electric boiler

How to make an induction boiler yourself?The sim­plic­i­ty of the design allows home crafts­men to make an induc­tion wine heat­ing boil­er on their own. In the man­u­fac­ture of the sim­plest ver­sion of such a heater you will need to pur­chase a high-fre­quen­cy weld­ing invert­er.

It is desir­able that it be equipped with a device for smooth­ly adjust­ing the cur­rent. The pow­er of the struc­ture depends on the mag­ni­tude of the weld­ing cur­rent (at least 15 amperes).

You should also pre­pare the fol­low­ing mate­ri­als:

  • thick-walled plas­tic pipe, the inner diam­e­ter of which is slight­ly less than 5 cm;
  • stain­less steel wire 7 mm;
  • adapters for con­nec­tion to the heat­ing sys­tem;
  • enam­elled cop­per wire;
  • fine met­al mesh.

The wire is cut into pieces about 5 cm. Then a plas­tic pipe is tak­en, at the bot­tom of which a met­al mesh is fixed, and then an adapter is attached to the base. This pipe will simul­ta­ne­ous­ly per­form two func­tions — it will become a sec­tion of the heat­ing sys­tem pipeline and the basis of an induc­tion coil.

The inside of the pipe is com­plete­ly filled with wire scraps.. They will serve as a mate­r­i­al heat­ed by an elec­tro­mag­net­ic field, and a fixed met­al mesh will pre­vent them from falling into the pipeline. Then an adapter is also installed on the top of the plas­tic pipe.

The next stage of work will be the man­u­fac­ture of the coil. Around the base of a plas­tic pipe filled with wire scraps, 90 turns of pre­pared cop­per wire are care­ful­ly wound. The wire should be locat­ed in the mid­dle of the pipe.

The fin­ished device is installed using adapters in the gap of the pipeline of the heat­ing sys­tem. Instal­la­tion is strict­ly ver­ti­cal.

After instal­la­tion, the coil should be con­nect­ed to a high-fre­quen­cy invert­er, and the heat­ing sys­tem should be filled with coolant. The heat­ing device must be con­nect­ed to earth. Now you can start using the heat­ing device made by your­self.

To pre­vent heat loss and a more aes­thet­ic appear­ance, a heat-insu­lat­ing cas­ing should be made.

If we cal­cu­late the funds spent on the pur­chase of com­po­nents for the man­u­fac­ture of a home-made VIN boil­er, then it is obvi­ous that its cost will be much less than the fin­ished prod­uct pur­chased in the store.

A study of con­sumer demand in the boil­er equip­ment mar­ket shows that most of the buy­ers who use elec­tric­i­ty for heat­ing their homes pre­fer mod­ern fac­to­ry-made induc­tion boil­ers equipped with var­i­ous secu­ri­ty sys­tems, pow­er­ful and eco­nom­i­cal. Such heat­ing equip­ment of a new gen­er­a­tion is becom­ing more pop­u­lar every year.
