Choosing the most economical way to heat your garage


Most motorists use the garage not only for its intend­ed pur­pose, but also as a place where you can take a break from house­hold chores, do a hob­by or do some house­hold chores. In order to stay com­fort­able in the garage even in win­ter, the room must be some­how heat­ed.

In order for heat­ing to be eco­nom­i­cal, it is nec­es­sary to know the fea­tures of exist­ing heat­ing meth­ods, since you can choose the best one for your­self only tak­ing into account the spe­cif­ic sit­u­a­tion and a num­ber of fac­tors: the dimen­sions of the room, its dis­tance from hous­ing, the avail­abil­i­ty of fuel con­sumed, the bud­get for pro­vid­ing heat to the garage, etc. d.

Heating Options for a Standard Single Car Garage

The most pop­u­lar and most eco­nom­i­cal way is to heat the garage with elec­tric­i­ty, espe­cial­ly if the build­ing is locat­ed at some dis­tance from the house, has small dimen­sions and is not vis­it­ed often in win­ter.

There are sev­er­al ways to heat a garage space using elec­tric­i­ty.


Mod­els of elec­tric con­vec­tors for use in garages and oth­er tech­ni­cal premis­es

A reli­able and effi­cient device, the prin­ci­ple of oper­a­tion of which is based on air con­vec­tion ini­ti­at­ed by heat­ing ele­ments — cold air enters the device from below and, heat­ing up upon con­tact with a heat­ing ele­ment, ris­es warm to the top.

Con­vec­tors are avail­able in floor, wall or uni­ver­sal ver­sions — on sup­port legs, with brack­ets for wall mount­ing or equipped with both mount­ing options. The lat­ter type is espe­cial­ly con­ve­nient, as it allows you to com­pact­ly place the heater on the wall with the pos­si­bil­i­ty of quick dis­man­tling and instal­la­tion next to the car — at the place of repair.

Advan­tages of an elec­tric con­vec­tor:

  • fast heat­ing to work­ing con­di­tion;
  • heat­ing in auto­mat­ic mode — a cer­tain tem­per­a­ture val­ue is man­u­al­ly set, upon reach­ing which the device turns off and resumes heat­ing the room only when the air cools by 1 degree;
  • safe oper­a­tion and ease of main­te­nance;
  • dura­bil­i­ty;
  • the pos­si­bil­i­ty of using in rooms with high humid­i­ty and pol­lu­tion, since the oper­at­ing ele­ments of the device are closed by a pro­tec­tive case.

Dis­ad­van­tages of the con­vec­tor:

  • high­er cost com­pared to some oth­er types of elec­tric heaters (quartz);
  • the achieve­ment of the effect of the work of the con­vec­tor in the garage occurs after at least half an hour of time;
  • increased elec­tric­i­ty con­sump­tion.

fan heater

Prin­ci­ple of oper­a­tion: a heat exchang­er (heat­ing ele­ments or a spi­ral) is heat­ed by means of elec­tric­i­ty, the air from the room is blown into the heater by a fan, passed between the heat­ing ele­ments and returned to the garage already hot.

Advan­tages of a fan heater:

  • envi­ron­men­tal friend­li­ness — the absence of any emis­sions into the sur­round­ing space dur­ing work;
  • con­ve­nience of adjust­ing the inten­si­ty of heat­ing — there are switch­es for heat­ing modes (turn­ing off part of the heat­ing ele­ments) and fan speed;
  • small dimen­sions and mobil­i­ty — can be installed any­where in the garage;
  • the pos­si­bil­i­ty of focused heat­ing of zones or objects;
  • rapid heat­ing of the room;
  • equip­ment with auto­mat­ic shut­down devices in case of over­heat­ing or cap­siz­ing;
  • the pos­si­bil­i­ty of addi­tion­al self-com­ple­tion with an electro­mechan­i­cal ther­mo­stat for auto­mat­i­cal­ly main­tain­ing the set tem­per­a­ture in the room;
  • low cost of elec­tri­cal appli­ances of small and medi­um pow­er;
  • ease of use and main­te­nance.

Like any unit The fan heater also has dis­ad­van­tages.which must be tak­en into account:

  • heat­ing-relat­ed decrease in air humid­i­ty in the room;
  • the pres­ence of a dust accu­mu­la­tion fac­tor on the heat­ing ele­ments, which is fraught with fire or, at least, an unpleas­ant smell in the garage;
  • noise caused by the oper­a­tion of the fan;
  • increased elec­tric­i­ty con­sump­tion.

Despite these short­com­ings, the use of a fan heater is the most pop­u­lar heat­ing for a garage.

heat gun

Light­weight Tim­berk heat gun with han­dle for easy porta­bil­i­ty

A com­pact and easy-to-use device that pro­vides fast and effi­cient heat­ing of the garage. It dif­fers from a fan heater by sev­er­al times high­er pow­er of heat­ing ele­ments. The device is based on elec­tric heaters and a high-per­for­mance fan, which pro­vides inten­sive air blow­ing of the heat­ing ele­ments, caus­ing the rapid dis­tri­b­u­tion of heat in the room.

Con­nec­tion of heat guns of increased pow­er requires a three-phase pow­er sup­ply with a volt­age of 380 V, less pow­er­ful units are designed for 220 V.

In garages of a small area, the use of heat guns cre­ates dust in the air, so they can be effec­tive­ly used there only if the room is kept clean at all times, includ­ing through high-qual­i­ty fin­ish­ing of build­ing envelopes.

Infrared heater

Infrared heaters in var­i­ous designs: tri­pod, wall and ceil­ing

The oper­a­tion of the device is based on the emis­sion of infrared rays, which, reach­ing the sur­face of objects in the path of prop­a­ga­tion, heat them, and those, in turn, give off heat to the room. Such devices are some­times referred to as UFO heaters, but UFO, the com­mon Cyril­lic abbre­vi­a­tion of the same name, has noth­ing to do with ultra­vi­o­let radi­a­tion.

UFO heaters are avail­able in var­i­ous sizes and capac­i­ties, they can be on a leg or designed to be mount­ed on a ver­ti­cal or hor­i­zon­tal base (wall, ceil­ing). Pro­vid­ed that the hous­ing is water­proof or placed under a canopy, infrared heaters can also be used in front of the garage on the street.

Advan­tages of IR heaters:

  • eco­nom­i­cal con­sump­tion of elec­tric­i­ty;
  • ease of oper­a­tion and instal­la­tion;
  • reli­a­bil­i­ty, safe­ty and envi­ron­men­tal friend­li­ness.

The dis­ad­van­tage of infrared heaters when used in a lim­it­ed garage space is the effect of IR rays on a small area, which caus­es less heat trans­fer from objects into the air. But when focus­ing radi­a­tion in the direc­tion of the actu­al zone, these heaters are quite effec­tive.

Impor­tant! Sig­nif­i­cant heat­ing of the body of UFO heaters dur­ing oper­a­tion requires cau­tion in han­dling the device in a cramped garage.

Water heating of a large capital garage


The most famil­iar to con­sumers is a water heat­ing sys­tem, the use of which in spa­cious garages is jus­ti­fied by many fac­tors, includ­ing the pos­si­bil­i­ty of do-it-your­self instal­la­tion. If the cost of pur­chas­ing a heat­ing boil­er, radi­a­tors and oth­er com­po­nents of the garage own­er does not both­er, then water heat­ing is the best way to heat a large garage.

The oper­a­tion of a garage water heat­ing sys­tem requires com­pli­ance with the fol­low­ing rules:

  • equip enclos­ing struc­tures, includ­ing gates, with insu­la­tion — this will give up to 40% ener­gy sav­ings;
  • use non-freez­ing liq­uid as a coolant — this will elim­i­nate the need to drain water dur­ing a long absence of the own­er;
  • to avoid dam­age, use heat­ing radi­a­tors for indus­tri­al use, anti-van­dal design.

If the dis­tance of the garage is not more than 20 m from the house, you can con­nect it to the home heat­ing sys­tem (in the case of autonomous heat­ing — with suf­fi­cient pow­er of the heat­ing boil­er). But heat­ing a garage of a large area will require a sig­nif­i­cant addi­tion­al con­sump­tion of coolant, that is, the instal­la­tion of a com­mon high-pow­er boil­er, the oper­a­tion of which in the sum­mer will not be eco­nom­i­cal­ly jus­ti­fied. There­fore, in a spa­cious garage, it is more expe­di­ent to arrange an autonomous heat­ing sys­tem and install an indi­vid­ual boil­er. After mak­ing such a deci­sion, it is nec­es­sary to deter­mine the opti­mal fuel for spe­cif­ic con­di­tions, under which the heat­ing boil­er will be pur­chased.


In terms of the cost of an ener­gy car­ri­er (nat­ur­al gas), this is the most eco­nom­i­cal way to heat a garage, but it comes with hid­den costs:

  • reg­is­tra­tion of design and per­mit doc­u­men­ta­tion;
  • pay­ment for the work of licensed spe­cial­ists in the instal­la­tion of gas equip­ment;
  • costs for ven­ti­la­tion and removal of com­bus­tion prod­ucts;
  • costs for main­te­nance work on the boil­er;
  • pos­si­bly the nec­es­sary con­struc­tion and sub­se­quent main­te­nance of the chim­ney.

Alter­na­tive­ly, infrared gas heaters, heat­ing pan­els, con­vec­tors that con­sume liq­ue­fied propane and butane in cylin­ders can be used to heat the garage — this elim­i­nates the need to go to the author­i­ties, but adds the prob­lem of pro­vid­ing fuel.

Fea­tures of gas heat­ing:

  • advan­tages — a high lev­el of automa­tion of the heat­ing sys­tem, when using nat­ur­al gas — the con­stant avail­abil­i­ty of an ener­gy car­ri­er in the main, effi­cien­cy and high effi­cien­cy of gas equip­ment;
  • dis­ad­van­tages — the pres­ence of a risk fac­tor for explo­sion, fire or car­bon monox­ide poi­son­ing.

When using gas heat­ing, the own­er of the build­ing must espe­cial­ly strict­ly observe the safe­ty require­ments in his garage.

A good option for a garage is a steam-drop type con­dens­ing auto­mat­ic unit, which is up to 15% more eco­nom­i­cal than oth­er mod­els, as it is able to work effi­cient­ly at low gas pres­sure. In the heat exchang­er of such a boil­er, water from being heat­ed by a gas burn­er turns into steam, and then again con­dens­es into a liq­uid state, which is accom­pa­nied by the release of heat. Such boil­ers are pro­duced in floor and wall ver­sions. For a garage, the sec­ond option is prefer­able, exclud­ing the pos­si­bil­i­ty of tip­ping over when per­form­ing some work.



Heat­ing with an elec­tric boil­er is a rather expen­sive solu­tion to the heat­ing prob­lem for a garage. If there is no alter­na­tive type of fuel, then it is bet­ter to use elec­tri­cal appli­ances (con­vec­tors, fans, heat guns, UFO heaters — described in detail above).

When using elec­tric heat­ing equip­ment indoors with an open arrange­ment of heat­ing ele­ments (coils, heat­ing ele­ments), it is nec­es­sary to remove flam­ma­ble and com­bustible mate­ri­als (fuels and lubri­cants, sol­vents, paints, tow, etc.) from the garage.

We also rec­om­mend — We make steam heat­ing in the garage with our own hands.

Today, sol­id fuel boil­ers are in demand by home­own­ers and indus­tri­al build­ings along with gas equip­ment. The fuel is coal, saw­dust, fire­wood. This is a fair­ly eco­nom­i­cal heat­ing, well pro­vid­ing the room with heat.

Dis­ad­van­tages of heat­ing a garage with a sol­id fuel boil­er:

  • the need for smoke removal;
  • the need to allo­cate a sig­nif­i­cant area for arrang­ing a place to store fuel, which is not always pos­si­ble in a garage;
  • the dan­ger of being in the garage of every­thing that can ignite from a spark when the fire­box door is opened;
  • the need for reg­u­lar clean­ing of the fur­nace from ash, and pipes — from soot.

The most advanced and there­fore eco­nom­i­cal type of sol­id fuel boil­er is a pyrol­y­sis-type unit, where the fuel, under the influ­ence of high tem­per­a­tures, decom­pos­es into two com­po­nents — pyrol­y­sis gas and ash, each of which is burned almost with­out residue in a sep­a­rate cham­ber.

In most mod­els of pyrol­y­sis boil­ers, only wood, pel­lets and waste (not bulk) from the wood­work­ing indus­try are used as fuel. How­ev­er, uni­ver­sal units are also pro­duced, also designed for the use of coal and peat bri­quettes. The only com­mon con­di­tion for all mod­els is that in order for the boil­er to enter the pyrol­y­sis mode, the mois­ture con­tent of the fuel should not exceed 20%, oth­er­wise it will work like a con­ven­tion­al sol­id fuel heater.

How­ev­er, pyrol­y­sis-type boil­ers are expen­sive equip­ment, and there­fore not every con­sumer can afford to use them to heat a garage — it is real­ly eco­nom­i­cal to heat a garage with your own hands only when all com­po­nents of the process do not require sig­nif­i­cant costs.

It is not dif­fi­cult to build a stove by watch­ing the cor­re­spond­ing video.


Mining as a type of fuel

There are spe­cial fur­naces that use used engine oil as fuel, the con­sump­tion of which is up to 1 liter per hour.

The dis­ad­van­tage of this heat­ing method is the need to clean the oil in spe­cial instal­la­tions (you can make it your­self), since burn­ing used lubri­cat­ing flu­ids with­out first adapt­ing the fuel to the process is fraught with fail­ure of the fur­nace.

Air heating system for garage

Air heat­ing is not as pop­u­lar with garage own­ers as water heat­ing, but with its help you can not only heat, but also ven­ti­late the room.

The method con­sists in equip­ping the garage with an air duct with deflec­tors through which air is sup­plied, which is blown by a fan of a heat gun or fan heater and addi­tion­al­ly passed through an air fil­ter.

The main advan­tage of air heat­ing for a garage is the rapid simul­ta­ne­ous dry­ing of the entire vol­ume, which pre­vents the aggres­sive effect of mois­ture on the car and oth­er fur­nish­ings.


To reduce heat­ing costs, the own­er is rec­om­mend­ed to insu­late the out­side walls and ceil­ing in the garage, hav­ing pre­vi­ous­ly sealed all the cracks and holes. For ther­mal insu­la­tion of walls, you can use foam sheets, for the ceil­ing and floor — expand­ed clay. The use of min­er­al wool boards will require sub­se­quent water­proof­ing

A prop­er­ly select­ed garage heat­ing sys­tem will not only pro­vide a com­fort­able tem­per­a­ture in the room, pro­tect the build­ing enve­lope from damp­ness, but also pre­vent the devel­op­ment of cor­ro­sion on the met­al parts of the car, which is detri­men­tal to equip­ment.
