Which heater to choose for the garage?

[ad_1]

In most regions of Europe, the ques­tion of the need to equip a garage with heat­ing does not cause dis­putes — the air tem­per­a­ture in win­ter even in the south­ern regions drops below zero, not to men­tion the north of the coun­try. There­fore, the prob­lem of heat­ing garage box­es is dis­cussed only from the per­spec­tive of the econ­o­my and effi­cien­cy of a par­tic­u­lar heat­ing unit in rela­tion to spe­cif­ic con­di­tions.

Con­sid­er sev­er­al types of heaters pop­u­lar among motorists for heat­ing. indi­vid­ual garage and com­pare their char­ac­ter­is­tics.

Justification for arranging a garage with heating

The main pur­pose of a garage box is to store a car, but this room has many addi­tion­al func­tions that depend on the inter­ests of the own­er and are also not sec­ondary.

Argu­ments in favor of equip­ping a garage with heat­ing:

  • reduc­tion of damp­ness in a room peri­od­i­cal­ly heat­ed in win­ter — the car body cor­rodes less, the box can be used to store uten­sils and dry mate­ri­als, the fin­ish­ing of enclos­ing struc­tures lasts longer, the safe­ty of elec­tri­cal wiring is high­er;
  • facil­i­tat­ing engine start in win­ter;
  • the pos­si­bil­i­ty of per­form­ing repair, pre­ven­tive or main­te­nance work, regard­less of the out­side air tem­per­a­ture.

Impor­tant! Effi­cient, eco­nom­i­cal garage heat­ing is not real­is­tic with­out equip­ping its enclos­ing struc­tures with ther­mal insu­la­tion.

What the Law says about heating garage buildings

*

Hav­ing decid­ed to equip the garage with heat­ing, you should be aware that not only the result, but also the pro­ce­dure for your actions must com­ply with the cur­rent leg­is­la­tion of the EU.

The main leg­isla­tive act reg­u­lat­ing fire-fight­ing mea­sures in the EU today is the Decree of the Gov­ern­ment of the EU. “On the fire regime” No. 390 dat­ed April 25, 2012 (as amend­ed on Novem­ber 18, 2017).

Con­se­quences of non-com­pli­ance with fire safe­ty stan­dards in garage struc­tures

How­ev­er, there are oth­er fire safe­ty instruc­tions that con­tain more detailed require­ments for the pre­ven­tion of fires in garage build­ings for col­lec­tive and indi­vid­ual use, which are manda­to­ry. For exam­ple, the 2018 “Instruc­tion on Safe­ty for Garages” on 22 pages.

If a garage for indi­vid­ual use that is not adja­cent to build­ings of an iden­ti­cal pur­pose, then its heat­ing is equipped accord­ing to a project devel­oped by a design orga­ni­za­tion licensed for this type of activ­i­ty.

If the struc­ture is part of the coop­er­a­tive, the arrange­ment of this room with heat­ing is car­ried out after agree­ment with the chair­man — in accor­dance with the instruc­tions he has on fire safe­ty mea­sures, con­tain­ing cal­cu­la­tions and rules for a par­tic­u­lar orga­ni­za­tion.

Impor­tant! There is no uni­ver­sal fire safe­ty instruc­tion that thor­ough­ly takes into account the specifics of heat­ing any object.

Thus, all inde­pen­dent actions of garage own­ers for the instal­la­tion and use of heat­ing devices are car­ried out by them at their own per­il and risk.

Diesel heaters

*

Diesel fuel is an ener­gy car­ri­er that is avail­able both in terms of the avail­abil­i­ty of fuel and lubri­cants on the mar­ket and in terms of price. In addi­tion, the volatil­i­ty of diesel fuel is low­er than that of kerosene, mak­ing it safer for domes­tic use. There­fore, as heaters for the garage, diesel fuel heat gen­er­a­tors con­sis­tent­ly occu­py lead­ing posi­tions.

A gen­er­al­ized descrip­tion of the “diesel heaters” group will not give the desired idea about these units, the types of which dif­fer in design and tech­ni­cal char­ac­ter­is­tics. For these rea­sons, we will con­sid­er one mod­el of each type of diesel fuel heaters that are pop­u­lar with garage own­ers.

Diesel heat gun of indi­rect heat­ing BALLU BHDN-20 of the TUNDRA series

Solar heaters of indi­rect heat­ing dif­fer from direct-act­ing units in that their com­bus­tion cham­ber is iso­lat­ed from the air of the heat­ed room, and the prod­ucts of com­bus­tion of diesel fuel dur­ing the oper­a­tion of the device are removed through the chim­ney to the out­side.

This design fea­ture is espe­cial­ly impor­tant for a garage — a room of lim­it­ed vol­ume, the con­tent of car­bon monox­ide in which, when heat­ed with a direct heat­ing diesel gun, will reach dan­ger­ous val­ues ​​in a mat­ter of min­utes.

A more com­plete pic­ture of liq­uid-fuel heat guns of indi­rect heat­ing will help a video demon­strat­ing the diesel heater for the Auro­ra TK-55 ID garage — a unit iden­ti­cal to the Bal­lu BHDN-20 described above:


Liq­uid fuel heaters of the com­pa­ny “SolaroGaz”

The line of heaters of this man­u­fac­tur­er is rep­re­sent­ed by five main mod­els, dif­fer­ing in pow­er (1.8 — 2.5 kW) and slight­ly con­struc­tive (reflec­tor geom­e­try, mate­r­i­al of man­u­fac­ture of the fur­nace).

The dimen­sions of these com­pact units are in the range of 30–40 cm, which does not require much space when placed and allows you to trans­port heaters in the trunk of any car. Heaters of the “SolaroGaz” line with a mod­est size allow you to main­tain a com­fort­able tem­per­a­ture in rooms with an area of ​​​​20–25 m2con­sum­ing an aver­age of only 0.2 liters of fuel per hour.

Liq­uid-fuel mini-heaters pro­duced by “SolaroGaz”

The vol­ume of fuel tanks of heaters, depend­ing on the mod­el, is dif­fer­ent (2.5 — 3.5 l), but on aver­age ensures con­tin­u­ous oper­a­tion of the device for 10 hours, and in econ­o­my mode up to 18 hours.

The unit is start­ed in the fol­low­ing sequence:

  • raise the divider with the emit­ter grid;
  • using the reg­u­la­tor, open the fuel sup­ply;
  • set fire to the wick with a lit match;
  • low­er the spread­er.

Advan­tages:

  • ver­sa­til­i­ty (two types of fuel used);
  • func­tion­al­i­ty (heat­ing and cook­ing);
  • com­pact­ness and low weight with suf­fi­cient pow­er;
  • effi­cien­cy — low fuel con­sump­tion;
  • ease of use;
  • afford­able cost (3–50 $).

Flaws:

  • fac­tors of open fire, includ­ing the need for peri­od­ic ven­ti­la­tion of the premis­es;
  • rel­a­tive­ly slow exit to the oper­at­ing mode;
  • when using diesel fuel, the release of odor dur­ing igni­tion and shut­down.

Impor­tant! It is for­bid­den to work with volatile fuels and lubri­cants in a garage with a liq­uid-fuel infrared heater run­ning, as well as to direct the heat rays of the burn­er direct­ly towards com­bustible mate­ri­als, gas cylin­ders, gas pipelines, elec­tri­cal wiring, etc. is pro­hib­it­ed.

Gas heat generators

As equip­ment for heat­ing a garage, gas heaters are some­what infe­ri­or in pop­u­lar­i­ty to diesel heaters, since con­nect­ing a garage build­ing to a nat­ur­al gas line requires project devel­op­ment, and using bot­tled propane or butane is much more expen­sive. How­ev­er, in regions with an aver­age length of the heat­ing sea­son, gas heaters apply in garage build­ings quite often.

Heat­ing the garage with a propane gas heater

Gas heaters are divid­ed into infrared and con­vec­tion action. In both types of units, heat is gen­er­at­ed by burn­ing gas, but the devices dif­fer in the way they trans­fer heat ener­gy.

From the per­spec­tive of ease of use in the garage, con­sid­er sam­ples of com­pact units.

Infrared gas heater BALLU BIGH‑3 —

An exam­ple of a mod­ern ener­gy-sav­ing heat­ing device that has the func­tion­al­i­ty and effi­cien­cy required for a garage.

The device is con­nect­ed through a reduc­er to a cylin­der with propane or butane and is sent to the actu­al area.

After igni­tion of the burn­er, the ceram­ic pan­el, which emits infrared waves, is heat­ed. Infrared radi­a­tion heats the sur­faces of objects locat­ed on the path of prop­a­ga­tion, and then the heat­ed inte­ri­or gives off heat to the air of the room.

*

The mod­el is con­ve­nient for local direc­tion­al heat­ing of zones and objects, which is con­ve­nient when repair­ing a car in a garage. In addi­tion, the adjustable stand allows you to direct the radi­a­tion upwards and use the device for heat­ing water or cook­ing.

Main char­ac­ter­is­tics:

  • igni­tion — man­u­al;
  • fuel — propane, butane;
  • heat dis­si­pa­tion pow­er — 3 kW (max);
  • heat­ed area — up to 30 m2;
  • fuel con­sump­tion — up to 200 ml / h;
  • heater dimen­sions — 22.5x21.5x22.1 cm;
  • loaded weight — 2.2 kg.

Advan­tages of the mod­el:

  • com­pact­ness;
  • prof­itabil­i­ty;
  • high-qual­i­ty paint and var­nish cov­er­ing of the case;
  • ceram­ic emit­ter of class A pro­tect­ed design.

Impor­tant! The sell­ers of BALLU BIGH‑3 present the heat­ing pan­el as not sub­ject to defor­ma­tion from con­tact with water, how­ev­er, the degree of this resis­tance is uncer­tain, there­fore, in a garage envi­ron­ment where a car wash is prac­ticed, this IR heater should not come into con­tact with mois­ture.

Gas con­vec­tors they work accord­ing to a dif­fer­ent prin­ci­ple — the gas burn­ing in the device heats the met­al heat exchang­er plate, which, in con­tact with the room air, ini­ti­ates the for­ma­tion of con­vec­tive flows. The com­bus­tion of gas takes place in the body of the unit iso­lat­ed from the heat­ed vol­ume, and the com­bus­tion prod­ucts are dis­charged out­side through a coax­i­al or ordi­nary chim­ney.

Due to the removal of com­bus­tion prod­ucts to the street, heat loss­es dur­ing heat­ing by such a device are sig­nif­i­cant, there­fore, the heat exchang­ers of con­vec­tors, to ensure suf­fi­cient heat trans­fer, are made much larg­er than the heat­ing pan­els of infrared gas heaters.

Cylin­der-oper­at­ed con­vec­tor heater

The oper­a­tion of gas con­vec­tors requires a sig­nif­i­cant gas flow, so they are rarely used to heat garages. In addi­tion, these heaters enter the oper­at­ing mode slow­ly, and in the garage, the effect of the unit should be fast.

Impor­tant! When equip­ping a garage with a gas con­vec­tor with an open com­bus­tion cham­ber, the room must be pro­vid­ed with ven­ti­la­tion with three air exchanges per hour.

Electric heaters

For garage heat­ing, elec­tric heat gen­er­a­tors are the safest to oper­ate. In addi­tion, the vast major­i­ty of garage build­ings are ini­tial­ly elec­tri­fied, and the use of elec­tric heaters does not require addi­tion­al mea­sures — chim­ney, ven­ti­la­tion, fuel prob­lems, etc.

Elec­tric heater based on heat­ing ele­ments

With a rel­a­tive­ly short stay of a per­son in the garage, the cost of elec­tric­i­ty for heat­ing will not be sig­nif­i­cant, although elec­tric­i­ty is not a cheap ener­gy car­ri­er.

In con­nec­tion with the above fac­tors, an elec­tric heater in a garage build­ing is a com­mon unit.

Reli­able old-style elec­tric heat gen­er­a­tor

The heat­ing device that we choose for the garage must cor­re­spond to the capac­i­ty in which the room is used.

If the oper­at­ing mode is half an hour vis­its every few days, then a rea­son­able solu­tion would be to pur­chase a small spi­ral or heat­ing ele­ment with a fan. An elec­tric tri­pod-mount­ed IR heater will also be effec­tive.

When the garage is used as a full-fledged repair shop, it is nec­es­sary to con­sid­er more iner­tial, but at the same time ener­gy-sav­ing types of heat­ing units. A ratio­nal solu­tion is a home-made reg­is­ter made of steel pipes with a heat­ing ele­ment embed­ded in the low­er part, filled with antifreeze or trans­former oil.

Hand­made elec­tric heat­ing reg­is­ters

Impor­tant! Accord­ing to the safe­ty require­ments for the oper­a­tion of elec­tri­cal appli­ances, all elec­tri­cal equip­ment in the garage must be ground­ed — to the ground loop or through the third core on the sup­ply cable.

Conclusion

In today’s vari­ety of types of heat­ing equip­ment offered by domes­tic and for­eign man­u­fac­tur­ers, it is not dif­fi­cult to choose a heater for a garage.

How­ev­er, when pur­chas­ing a device with ref­er­ence to the exist­ing con­di­tions, first of all, it is nec­es­sary to focus on the safe­ty of oper­a­tion — choose a design with sev­er­al lev­els of pro­tec­tion and fol­low the safe­ty rules. The sever­i­ty of the con­se­quences of friv­o­li­ty in this direc­tion is unpre­dictable, espe­cial­ly in garage coop­er­a­tives.

The main essence of the article

  1. The pos­si­bil­i­ty of heat­ing the garage space is a guar­an­tor of the long-term safe­ty of the car and stored uten­sils, com­fort­able con­di­tions for the pro­duc­tion of repair work.
  2. Ensur­ing com­fort in the garage should not be con­trary to fire safe­ty rules. The use of any home­made heaters in garages is pro­hib­it­ed.
  3. Liq­uid fuel heaters are pop­u­lar among garage own­ers, but oper­at­ing units, even indus­tri­al ones, in a cramped room is asso­ci­at­ed with an increased risk.
  4. Gas heat­ing units in the process of oper­a­tion almost do not leave harm­ful sub­stances after com­bus­tion, but gas is a fuel of increased dan­ger. Instal­la­tion, oper­a­tion of gas-fired units require design cal­cu­la­tions and coor­di­na­tion with licens­ing author­i­ties.
  5. Elec­tric heaters are the safest devices for garage con­di­tions, so the appar­ent high cost of elec­tric­i­ty will ensure the cost-effec­tive­ness of heat­ing with elec­tric­i­ty in the long run.
