Antifreeze for heating system


A coun­try house, cot­tage or cot­tage will become warm and cozy when they have a nor­mal, full-fledged heat­ing sys­tem. Due to the fact that equip­ment for water heat­ing is wide­ly rep­re­sent­ed on the mar­ket today, there is no dif­fi­cul­ty in installing and orga­niz­ing an autonomous heat­ing sys­tem for your own home! There remains an impor­tant ques­tion that own­ers of sub­ur­ban hous­ing often face, how to increase the dura­bil­i­ty of a work­ing water boil­er, pipelines and radi­a­tors! What hap­pens if antifreeze is poured into the heat­ing sys­tem of a house?

The topic of antifreeze when it comes to the efficiency of a hot water heating system?

Tra­di­tion­al­ly, it is con­sid­ered that it is bet­ter to fill a water heat­ing com­plex with water, which is the most com­mon and afford­able coolant. It takes into account the fact that water can be found every­where and always. Water has ide­al phys­i­cal prop­er­ties, among which heat capac­i­ty, heat trans­fer and vis­cos­i­ty are the main ones. Despite the appar­ent advan­tages, water has a sig­nif­i­cant and sig­nif­i­cant draw­back — it freezes at low tem­per­a­tures. Dur­ing the heat­ing sea­son, this is fraught with big trou­bles. If you do not adhere to the oper­at­ing con­di­tions of the water boil­er and the entire heat­ing sys­tem in the win­ter, freez­ing of the coolant threat­ens with cat­a­stroph­ic con­se­quences. For our cli­mate, severe frosts are not uncom­mon, as a result, frozen water in the heat­ing sys­tem of the house breaks pipelines and dis­ables radi­a­tors.

It should be remem­bered: The pres­ence of water as a heat car­ri­er in the heat­ing sys­tem of a coun­try house requires a con­stant­ly oper­at­ing boil­er to main­tain a pos­i­tive tem­per­a­ture in the sys­tem. Heat­ing must be con­stant, even in the absence of house­hold needs, which leads to sig­nif­i­cant fuel over­runs and finan­cial costs.

A com­fort­able coun­try house, equipped with a water heat­ing com­plex, needs con­stant super­vi­sion. An unex­pect­ed fail­ure of the boil­er automa­tion, pow­er out­ages will cause a com­plete defrost­ing of the entire sys­tem. The con­se­quences can be the sad­dest. Not only will we have to change most of the pipes and radi­a­tors, but in some cas­es also elim­i­nate the con­se­quences of the flood.
A warm house after such an emer­gency is ready to turn into a cold and frozen room, unsuit­able for liv­ing. Antifreeze for home heat­ing will help solve the prob­lem, a sub­stance that suc­cess­ful­ly resists low tem­per­a­tures and does not lose its basic phys­i­cal prop­er­ties. How to pour antifreeze into the sys­tem, in what pro­por­tion to add it to water or use a con­cen­trate, can be found on the web­sites of numer­ous com­pa­nies involved in equip­ment and instal­la­tion of autonomous heat­ing.

The heat­ing sys­tem in this case will remain func­tion­al through­out the entire peri­od of oper­a­tion, ensur­ing that your warm home will be reli­ably pro­tect­ed from frost. Prop­er­ly select­ed coolant will pro­vide high per­for­mance and tech­no­log­i­cal char­ac­ter­is­tics of the water boil­er. In each indi­vid­ual case, it is nec­es­sary to choose a spe­cif­ic brand of antifreeze, which includes the nec­es­sary com­po­nents and addi­tives that ensure reli­able heat­ing oper­a­tion. Switch­ing to non-freez­ing liq­uid in the heat­ing sys­tem as a coolant is the right step and quite jus­ti­fied.

If you decide to increase the pro­tec­tion of your autonomous heat­ing sys­tem with antifreeze, you need to care­ful­ly and bal­anced­ly approach this issue.

Antifreeze as a coolant. Main properties and characteristics


For water heat­ing in a pri­vate house, the main aspect is the com­pli­ance of the coolant with the basic require­ments. The sub­stance poured into the sys­tem must:

  • ful­ly ensure effi­cient heat trans­fer;
  • for a long time not to lose their basic phys­i­cal and chem­i­cal prop­er­ties;
  • not form scale and oth­er by-prod­ucts of oper­a­tion as a result of heat­ing;
  • with­stand low tem­per­a­tures, pre­vent­ing freez­ing.

Eval­u­at­ing water as a coolant, judg­ing by the char­ac­ter­is­tics described above, the con­clu­sion sug­gests itself — ordi­nary water is not very suit­able for these pur­pos­es. A warm house with such a coolant becomes unre­li­able. Despite the fact that water has a high heat capac­i­ty and good flu­id­i­ty, water has a high cor­ro­sive effect and quick­ly los­es its basic phys­i­cal prop­er­ties under the influ­ence of low tem­per­a­ture. For heat­ing, the qual­i­ty and com­po­si­tion of water is of great impor­tance. A large per­cent­age of cal­ci­um and mag­ne­sium con­tent in water caus­es scale for­ma­tion as a result of pro­longed heat­ing to tem­per­a­tures above 800C. If the water qual­i­ty is poor, the water boil­er, the pipes in the sys­tem are cov­ered with scale from the inside, which sig­nif­i­cant­ly affects the qual­i­ty of heat­ing. Antifreeze for the heat­ing sys­tem of a coun­try house in this case com­pares favor­ably with water, sig­nif­i­cant­ly increas­ing the oper­a­tional capa­bil­i­ties of an autonomous heat­ing sys­tem.

Antifreeze is known to most of us thanks to its use in auto­mo­tive tech­nol­o­gy. The name already says that the main qual­i­ty of this sub­stance is the absence of a reac­tion to the effects of low tem­per­a­tures. The freez­ing point of this liq­uid can reach ‑650C. Only when the tem­per­a­ture drops below ‑700With comes the process of crys­tal­liza­tion of the sub­stance. The rea­son for this behav­ior of the liq­uid is the high con­cen­tra­tion of active com­po­nents in the sub­stance itself.

Due to its prop­er­ties and good inter­ac­tion with water, antifreeze can be added to the water heat­ing sys­tem, there­by adjust­ing the freez­ing tem­per­a­ture of the entire coolant. The non-freez­ing com­po­si­tion added to the water in a ratio of 50/50 pro­vides it with the nec­es­sary flu­id­i­ty even at a tem­per­a­ture of ‑400C. The boil­er and the pip­ing sys­tem in this case are reli­ably and well pro­tect­ed from freez­ing dur­ing a rapid decrease in the tem­per­a­ture of the atmos­pher­ic air. The high­er the per­cent­age of antifreeze in water, the low­er the freez­ing point of the coolant and, accord­ing­ly, the high­er the boil­ing point.

Today, antifreeze of var­i­ous brands is quite wide­ly rep­re­sent­ed on the mar­ket. The main qual­i­ties and char­ac­ter­is­tics depend on the type of addi­tives used in the flu­id. Each addi­tive endows the sub­stance with cer­tain prop­er­ties, allows it to bet­ter per­form the tasks assigned to it. For exam­ple, to improve the effi­cien­cy of autonomous heat­ing, addi­tives are often used that pro­vide:

  • pro­tec­tion of met­al com­po­nents from cor­ro­sion;
  • dis­so­lu­tion and removal of by-prod­ucts of heat­ing the coolant;
  • pro­tec­tion of var­i­ous kinds of syn­thet­ic gas­kets and seals from pre­ma­ture destruc­tion.

Water heat­ing in a house based on antifreeze is an effec­tive tool to ensure the safe­ty of heat­ing dur­ing the cold peri­od, to increase the life of the main ele­ments of the heat­ing sys­tem. A heat­ing com­plex filled with a coolant with the addi­tion of antifreeze will make a warm house reli­able and com­fort­able.

Impor­tant! Hav­ing giv­en pref­er­ence to antifreeze as a coolant for home heat­ing, it is nec­es­sary to use a sub­stance that meets the tech­no­log­i­cal require­ments of a water boil­er and oth­er para­me­ters of the main ele­ments of the heat­ing sys­tem.


How to choose antifreeze for your home heating system

Cur­rent­ly, domes­tic indus­try and for­eign man­u­fac­tur­ers pro­duce var­i­ous types of antifreeze. The main dif­fer­ence in each brand is the base com­po­nent. For heat­ing, the best option is antifreeze, which is based on a saline solu­tion, an alco­hol base. There are more expen­sive brands that use propy­lene gly­col or eth­yl­ene gly­col. When choos­ing the most accept­able brand, it is impor­tant to pay atten­tion to the addi­tive that is part of the liq­uid. It is nec­es­sary to choose a liq­uid, tak­ing into account the para­me­ters of the water boil­er, in the user instruc­tions of which the man­u­fac­tur­er usu­al­ly indi­cates the exist­ing restric­tions and require­ments for the brand of antifreeze.

This type of antifreeze is avail­able as a con­cen­trate or as a ready-to-use solu­tion. As a rule, these antifreezes are called house­hold.

At the house­hold lev­el, propy­lene gly­col-based antifreezes are suc­cess­ful­ly used. Accord­ing to its phys­i­cal prop­er­ties, this sub­stance has the char­ac­ter­is­tics nec­es­sary for an ide­al coolant. The only draw­back is the rel­a­tive high cost of this brand of antifreeze. The pri­or­i­ty advan­tage of propy­lene gly­col antifreeze is the envi­ron­men­tal safe­ty of the main com­po­nents and harm­less­ness to the human body.

A cheap­er option would be to use eth­yl­ene gly­col-based antifreeze. The sub­stance does not freeze at ‑600C. These grades meet all the nec­es­sary tech­ni­cal require­ments for coolants, includ­ing flu­id­i­ty and good heat trans­fer. Nev­er­the­less, heat­ing a coun­try house with antifreeze on eth­yl­ene gly­col has lost its rel­e­vance today due to the tox­i­c­i­ty of eth­yl­ene gly­col. The low cost and rather high tech­no­log­i­cal char­ac­ter­is­tics of the sub­stance, in com­par­i­son with the threat to health safe­ty, are no longer a pri­or­i­ty. Which antifreeze to give pref­er­ence to, you choose. In any case, the choice is asso­ci­at­ed with the need to com­pare a num­ber of tech­ni­cal para­me­ters.

There are also antifreezes on sale based on a solu­tion of bischof­ite and glyc­erin, which have an absolute­ly neu­tral state with respect to the exter­nal envi­ron­ment and are not aggres­sive.

Hav­ing famil­iar­ized your­self with the advan­tages of antifreeze for an autonomous heat­ing sys­tem, you should not rush head­long into the store and make a pre­ma­ture pur­chase. With all the appar­ent advan­tages of using antifreeze, there are a num­ber of neg­a­tive points that must be con­sid­ered.

Before pour­ing antifreeze into the heat­ing sys­tem, you must remem­ber! You should nev­er pour pure antifreeze into the heat­ing sys­tem, which only con­tains propy­lene gly­col dis­solved in water. The absence of addi­tives in the liq­uid will cre­ate addi­tion­al dif­fi­cul­ties for you in the future.

Neglect of safe­ty mea­sures and tech­ni­cal instruc­tions will lead to the fact that the pip­ing sys­tem at the joints may leak. Rub­ber exposed to pure propy­lene gly­col tends to warp. Addi­tives pre­vent the occur­rence of chem­i­cal process­es, the result of which is dam­age to the con­nect­ing seals. With the help of addi­tives, you can also avoid the rapid for­ma­tion of scale and foam in the sys­tem.

Com­pe­tent and ratio­nal use of antifreezes in the oper­a­tion of autonomous heat­ing sys­tems will allow you to for­get about defrost­ing bat­ter­ies for­ev­er. With the use of addi­tives, as part of antifreeze, you will sig­nif­i­cant­ly increase the life of the water boil­er and all oth­er com­po­nents of the heat­ing sys­tem of a pri­vate house.
