Heating the garage with an electric boiler


A warm garage in the cold sea­son is a great solu­tion. One of the options can be safe­ly called an elec­tric boil­er for par­tial or com­plete heat­ing of the garage. The fact is that the ener­gy source used in most cas­es is already con­nect­ed to the room for the car. So there is no need to think about the pos­si­ble stor­age of fuel. In addi­tion, you do not need to con­stant­ly mon­i­tor the work — automa­tion will per­fect­ly cope with this.

Principle of operation

By and large, heat­ing for a garage looks exact­ly the same as for any oth­er room. Only few­er pipes and radi­a­tors are used. The process is as fol­lows: the coolant is heat­ed in the instal­la­tion, enters the radi­a­tors with the help of pipes. Hav­ing passed the entire heat­ing cir­cuit, the liq­uid is again in the boil­er.


What units are suitable for the garage?

There are many mod­els on the mar­ket. To weed out the unnec­es­sary and stop at one or at least a few, you need to find out for your­self a few key points:

  • how often or for how long the sys­tem will run;
  • Should this process be auto­mat­ed?
  • a work­shop or even some kind of pro­duc­tion will be addi­tion­al­ly locat­ed in the garage;
  • Do you need con­stant hot water?

It is quite obvi­ous that, hav­ing clar­i­fied all the points, it will be pos­si­ble to choose exact­ly the right equip­ment.

So, for exam­ple, if you need peri­od­ic heat­ing and hot water, you can find inex­pen­sive elec­tric heat­ing ele­ments. They will cost less than oth­ers. True, in this case it will be nec­es­sary to con­stant­ly man­age the sys­tem your­self. In addi­tion, you will need to mon­i­tor the flu­id lev­el. In this case, the room will warm up as quick­ly as pos­si­ble.

One or two loops?

If a small struc­ture is planned to be used not only for a car, it is bet­ter to think about more com­plex equip­ment. As for res­i­den­tial build­ings, elec­tric boil­ers can be sin­gle- and dou­ble-cir­cuit. The use of the lat­ter will be jus­ti­fied if there is a con­stant need for hot water. This view has both pos­i­tive and neg­a­tive sides:

  1. Heat­ing a garage with an elec­tric boil­er will cost an aver­age of 30% less if it is car­ried out by a sin­gle-cir­cuit unit. Oth­er­wise, the own­er of the premis­es will pay rel­a­tive­ly large amounts for use.
  2. If, nev­er­the­less, there is a need for water for house­hold needs, it is pos­si­ble to addi­tion­al­ly con­nect an indi­rect heat­ing boil­er to a sin­gle-cir­cuit appa­ra­tus. In this case, it will only work togeth­er with space heat­ing.
  3. You can also install a dou­ble-cir­cuit boil­er. It will be more prof­itable than a sin­gle-cir­cuit one togeth­er with an ordi­nary boil­er.
  4. Equip­ment for two cir­cuits is more expen­sive and has a short­er ser­vice life than a sim­ple instal­la­tion.

To choose exact­ly what you need, you need to accu­rate­ly under­stand the func­tions of the room and the plan of oper­a­tion of the unit.



Installing a boil­er in a garage that runs on elec­tric­i­ty is exact­ly the same as in any oth­er build­ing. It is nec­es­sary to place all the radi­a­tors over the area and con­nect them to the sys­tem. After that, install the boil­er itself in a suit­able place. In addi­tion, it is def­i­nite­ly worth intro­duc­ing a water fil­ter, a pump, an expan­sion tank, pres­sure and volt­age fus­es into the heat­ing (if this is not pro­vid­ed for in the unit itself).


  1. Envi­ron­men­tal friend­li­ness. Such types of instal­la­tions do not harm the envi­ron­ment and humans.
  2. Flames are not used. There is no need to install a chim­ney.
  3. Com­pared to oth­er types of boil­ers, the ini­tial cost is low­er than oth­ers.
  4. It is pos­si­ble to set up the equip­ment for the week ahead.


  1. The cost of oper­at­ing costs is high­er than with any oth­er units.
  2. Depen­dence on elec­tric­i­ty. As a result of inter­rup­tions, water can freeze, which will lead not only to rup­ture of pipes, but also to fail­ure of the appa­ra­tus.

Heat­ing the garage with an elec­tric boil­er is per­fect if it is already con­nect­ed to cur­rent. And at the same time, the own­er of the premis­es wants to get “com­fort­able” heat­ing. After all, it is almost impos­si­ble to set the desired tem­per­a­ture using a con­vec­tor or an oil cool­er, espe­cial­ly in a garage.

In addi­tion, many do not choose instal­la­tions on oth­er types of ener­gy car­ri­ers, as they do not want to some­how harm their health and pol­lute the envi­ron­ment.

Well, the use of such equip­ment has its advan­tages and dis­ad­van­tages com­pared to oth­er types of heat­ing. Before choos­ing an instal­la­tion, you def­i­nite­ly need to think about the pur­pos­es for which this is being done, and whether there is a need for it.
