We make steam heating in the garage with our own hands

[ad_1]

You can make steam heat­ing in the garage with your own hands quite quick­ly, because such a sys­tem has minor dif­fer­ences from liq­uid heat­ing cir­cuits, which are now the most com­mon. Both struc­tures are based on the boil­er and pip­ing design. The only dif­fer­ence is the coolant used. For steam heat­ing, this is super­heat­ed steam.

Principle of operation

Steam heat­ing is the heat­ing of a room with steam, which appears when water boils in a boil­er. After that, it enters the radi­a­tors through pipes.

The steam heat­ing sys­tem includes:

  • boil­er;
  • pipes;
  • radi­a­tors;
  • fire­box;
  • cir­cu­lar pump;
  • shut-off valves — exhaust valve and valves (steam ver­sion).

Atten­tion: The heat­ing sys­tem can be open or closed. In the first case, a pump is used to return the con­den­sate to the boil­er. If it is closed, the con­den­sate returns to the boil­er on its own, due to the pres­ence of a slight tech­no­log­i­cal slope of the pipes and under the influ­ence of grav­i­ty.

Accord­ing to the dis­tri­b­u­tion of pipes, the sys­tem can be one- or two-pipe. In the lat­ter case, steam pass­es through one pipe, and the result­ing con­den­sate returns to the tank through anoth­er. In this case, both pipes are closed in one cycle.

If the wiring is sin­gle-pipe, then steam and con­den­sate move along one pipe, while cre­at­ing extra­ne­ous sounds in the com­plex.

If a two-pipe sys­tem is usu­al­ly used to heat pri­vate hous­es, then its sin­gle-pipe coun­ter­part can also be used to heat a garage. After all, the dimen­sions of the garage are most often small, and the pro­duc­tiv­i­ty and pow­er of the boil­er is quite enough for its high-qual­i­ty heat­ing even in severe frosts. Although it is not for­bid­den to install a two-pipe sys­tem in the garage. Which one is more prefer­able is up to the own­er of the garage to decide.

Fuel and boiler

Atten­tion: For a steam heat­ing boil­er, liq­uid (diesel oil, fuel oil) or sol­id (coal, fire­wood) fuel can be used. Nat­ur­al gas can also be used, but is rarely used to heat a garage.

*
Boil­ers for steam heat­ing are of two types:

  1. Gas-pipe — low-pow­er, explo­sive with a sig­nif­i­cant increase in pow­er.
  2. Water tubes — with a large pow­er poten­tial, more mod­ern and, as a result, safer.

What­ev­er boil­er is used, its device is the same. It con­sists of a fur­nace, burn­er, drum and ash pan.

Calculation and installation

Hav­ing decid­ed to install steam heat­ing in the garage, you should care­ful­ly approach the design stage. The fol­low­ing cal­cu­la­tions must be made:

  1. Hydraulic. It allows you to set the char­ac­ter­is­tics of the con­den­sate and steam pipes.
  2. Ther­mal. It makes it pos­si­ble to cal­cu­late the geo­met­ric and oth­er char­ac­ter­is­tics of the bat­ter­ies.

You should care­ful­ly con­sid­er the choice of the boil­er and oth­er addi­tion­al equip­ment that will be required for steam heat­ing of the garage.

The instal­la­tion of a steam heat­ing sys­tem in a garage is sim­i­lar in tech­nol­o­gy to the arrange­ment of a room with a water heat­ing sys­tem, how­ev­er, due to the fact that steam is an aggres­sive heat car­ri­er of high tem­per­a­ture, the require­ments for mate­ri­als, assem­bly qual­i­ty and ensur­ing the safe oper­a­tion of the steam cir­cuit are espe­cial­ly high. There­fore, the char­ac­ter­is­tics of shut-off valves must meet the require­ments for oper­a­tion on steam pipelines, seal­ing fit­tings (sealants, gas­kets) must be steam and heat resis­tant, and the num­ber of mount­ing joints must be min­i­mal.

Despite the fact that the steam heat­ing sys­tem is con­sid­ered obso­lete, it is great for heat­ing the garage — if it is prop­er­ly cal­cu­lat­ed and installed, steam heat­ing is effec­tive even in severe frost, the room tem­per­a­ture can be adjust­ed, and the mech­a­nisms do not require spe­cial care.

Scheme

To achieve high-qual­i­ty garage heat­ing using steam heat­ing, you should choose the right equip­ment and mate­ri­als. Much depends on the cor­rect instal­la­tion of the sys­tem. It is for this that it is rec­om­mend­ed to draw up a project in advance. With it, you can find out which of their water heat­ing schemes will be most suit­able for your garage. Also, thanks to the project, it is pos­si­ble to deter­mine the length and posi­tion of all con­tours, includ­ing their branch­es, turns, etc. It is also indis­pens­able for choos­ing the place of instal­la­tion of the boil­er and radi­a­tors.

The choice of the opti­mal scheme is required to deter­mine the required steam pres­sure when heat­ing a par­tic­u­lar garage. It can be of four cat­e­gories, but since the area of ​​u200bu200bthe garage is usu­al­ly small, you can opt for ultra-low (vac­u­um-steam).

It can also be used to set how mois­ture will be returned back to the boil­er. There are two options — open and closed. In the first case, the return occurs due to the pres­ence of a pump that pumps it through a spe­cial tank. The closed method con­sists in the return of mois­ture by grav­i­ty, due to the pres­ence of high pres­sure.

Atten­tion: Thanks to the scheme, you can also find out the most suit­able cir­cuit, which can be sin­gle or dou­ble. For steam heat­ing, both options can be used. If the cir­cuit is sin­gle, in order to achieve the move­ment of steam and con­den­sate in the same direc­tion, it should be that there are the nec­es­sary angles and slopes. If the cir­cuit is dou­ble, the move­ment of the coolant and con­den­sate occurs through dif­fer­ent pipes.

Steam heat­ing for a garage must have a prop­er­ly drawn up dia­gram in order to deter­mine the required equip­ment para­me­ters. First of all, the pow­er of the boil­er. But, as already men­tioned, the area of ​​u200bu200bthe room is usu­al­ly small and there is no need to pur­chase a pow­er­ful boil­er to heat it.

When choos­ing, you should also con­sid­er the type of fuel that you intend to use for heat­ing. It should have a rea­son­able cost and be avail­able in the area where you live and, accord­ing­ly, your garage is locat­ed.

The mate­r­i­al of the pipes and their geo­met­ric char­ac­ter­is­tics should be tak­en into account. They must be select­ed to with­stand the pres­sure and steam in the sys­tem for the expect­ed life of the sys­tem. It is best to choose a pipe made of alloy steel, cop­per or rolled prod­ucts. Despite the fact that their cost can­not be called cheap, in this case, one should pay atten­tion to their reli­a­bil­i­ty. The effi­cien­cy and dura­bil­i­ty of steam heat­ing in the garage also depends on the mate­r­i­al from which the radi­a­tors are made and their dimen­sions.

Mounting

The instal­la­tion of a steam heat­ing sys­tem depends on the cho­sen scheme. You should also read all the rec­om­men­da­tions of the man­u­fac­tur­ers of the equip­ment used.

Atten­tion: It is nec­es­sary to take into account the dis­tance from the boil­er to the ceil­ing and walls of the garage. The lat­ter must be fire resis­tant. The room in which steam heat­ing will be installed must have a good ven­ti­la­tion sys­tem.

Heat­ing instal­la­tion includes the fol­low­ing steps:

  1. Site prepa­ra­tion for instal­la­tion.
  2. Boil­er and radi­a­tor instal­la­tion.
  3. Boil­er and radi­a­tor pip­ing.
  4. Tri­al run and check of cor­rect oper­a­tion.

By installing a steam heat­ing sys­tem in the garage, you will be able to feel com­fort­able in it while doing, for exam­ple, repair­ing your car. It will be warm even in the most severe frosts. The main thing is that it is designed and installed cor­rect­ly.

Before you start heat­ing the garage with this sys­tem, you should test it. This is nec­es­sary to check the tight­ness of the cir­cuit, because you should know in advance whether it can with­stand the oper­at­ing pres­sure. Also, dur­ing the tests, you can find out whether steam is even­ly sup­plied and whether it enters the con­den­sate pipe (if the wiring is two-pipe).

We rec­om­mend that you famil­iar­ize your­self with the link with the main arti­cle on the imple­men­ta­tion of heat­ing in the garage on your own.

What is a steam heating system

The com­po­si­tion of the sys­tem is quite sim­ple. It includes a device for gen­er­at­ing steam. A boil­er is usu­al­ly used as it. Radi­a­tors sim­i­lar to those used in water heat­ing sys­tems. You can not do with­out con­nect­ing ele­ments. These are fit­tings, pipes, etc. If the cir­cu­la­tion of the coolant in a nat­ur­al way in the sys­tem is not pos­si­ble, you will need to install a pump.

The prin­ci­ple of oper­a­tion of steam heat­ing with a pump is as fol­lows:

  1. In the heat exchange cir­cuit of the boil­er with burn­ing fuel, the water turns into steam, which moves through the pipes.
  2. The process of mois­ture con­den­sa­tion occurs in radi­a­tors. It is accom­pa­nied by a sig­nif­i­cant increase in tem­per­a­ture.
  3. Mois­ture flows first into the col­lec­tion tank, and then back into the tank. At the last stage, the “help” of the pump is need­ed.

Atten­tion: The steam heat­ing sys­tem can also be used with­out a pump. This is pos­si­ble if there is the nec­es­sary slope and the cor­rect loca­tion of all com­po­nents and con­nect­ing ele­ments.

Such a struc­ture has both pos­i­tive and neg­a­tive sides. Among the pos­i­tive ones can be dis­tin­guished:

  1. High speed of achiev­ing the effect — after start­ing the boil­er, the radi­a­tors will become hot quick­ly enough.
  2. High effi­cien­cy. It is almost 100%. Heat loss is min­i­mal, and its return is max­i­mum.
  3. The dimen­sions of the entire sys­tem are quite small. It can be eas­i­ly installed in the garage.
  4. It has good freeze resis­tance. If this hap­pened, when it is defrost­ed, there should not be any dam­age.

The dis­ad­van­tages of this struc­ture include:

  1. The sur­faces of radi­a­tors and pipes are so hot that, if touched, they can cause burns.
  2. Since such a sys­tem oper­ates in rather “hard” con­di­tions, this neg­a­tive­ly affects the dura­tion of its oper­a­tion.
  3. It is not pos­si­ble to reg­u­late the tem­per­a­ture of indi­vid­ual radi­a­tors.

As you can see, there are many advan­tages and dis­ad­van­tages of a steam heat­ing sys­tem with­out using a pump. And only you can choose which type of steam heat­ing will be the most ratio­nal.
