terms and types of work performance

Every­one knows that the effi­cient oper­a­tion of a heat­ing sys­tem (CO) depends on cor­rect­ly per­formed cal­cu­la­tions, well-cho­sen ele­ments and pro­fes­sion­al instal­la­tion. Soon­er or lat­er, process­es occur in any heat­ing sys­tem that sig­nif­i­cant­ly reduce its per­for­mance. Reg­u­lar “heal­ing”, pre­ven­tive mea­sures are required to main­tain the effi­cien­cy of the CO. This pub­li­ca­tion will address issues relat­ed to the main­te­nance of heat­ing sys­tems in a pri­vate house.


Inde­pen­dent or con­tract?

Each own­er of an autonomous heat­ing sys­tem is faced with the deci­sion of the ques­tion, who will do pre­ven­tive main­te­nance, car­ry out reg­u­lar main­te­nance, cur­rent or urgent repairs of the heat­ing sys­tem? There are only two options: the own­er or the ser­vice orga­ni­za­tion. In the case of inde­pen­dent work, the own­er of the heat­ing sys­tem must have the appro­pri­ate knowl­edge, know the types and terms of work. In the sec­ond case, the own­er must be able to finance the per­for­mance of the main­te­nance.

It is impor­tant to under­stand that the cost of per­form­ing work depends entire­ly on the design fea­tures and scheme of the CO, the “ser­vice pack­age” pro­vid­ed by the ser­vice orga­ni­za­tion, the com­plex­i­ty of the ele­ments used in the heat­ing sys­tem.

What and when to do

Water system maintenance schedule

The main­te­nance sched­ule for the heat­ing sys­tem includes the fol­low­ing activ­i­ties:

  • Peri­od­ic visu­al inspec­tion. These mea­sures relate to the state of the heat gen­er­a­tor, the col­lec­tor, the tight­ness of the pipeline and its con­nec­tion points, the fail­ure of shut-off valves, and the clean­ing of fil­ters. These activ­i­ties are car­ried out at least once a month.
  • Check­ing the con­di­tion of pump­ing equip­ment, the cor­rect­ness of read­ings of mea­sur­ing equip­ment (pres­sure gauges, ther­mome­ters) — once a week.
  • Main­te­nance of heat­ing devices is car­ried out before each heat­ing sea­son.
  • Air is removed after chang­ing the coolant, replac­ing CO ele­ments or elim­i­nat­ing emer­gency sit­u­a­tions.
  • Check­ing the work, as well as ser­vic­ing the heat­ing boil­er and automa­tion (smoke and car­bon monox­ide sen­sors) is car­ried out dur­ing the peri­od of com­plete main­te­nance of the heat­ing sys­tem (1 time per year) or in case of emer­gen­cies.

Impor­tant! All mea­sur­ing equip­ment requires manda­to­ry ver­i­fi­ca­tion, which is car­ried out by stan­dard­iza­tion and metrol­o­gy orga­ni­za­tions.

Why is this work required? Any leaks affect the pres­sure in CO (usu­al­ly 1.5 — 2 kg / cm2). The pres­ence of air pock­ets or dirty radi­a­tors reduce the effi­cien­cy of their heat trans­fer.

Any coolant con­tains sol­id par­ti­cles that are formed dur­ing the oper­a­tion of heat­ing sys­tems or enter it when fed from the water sup­ply. Such inclu­sions set­tle on the walls of the CO ele­ments, reduc­ing the flow area, hin­der the cor­rect oper­a­tion of the valves and lead to abra­sive wear of the equip­ment. The prob­lem is solved by fil­ters installed on var­i­ous sec­tions of the pipeline. That is why clean­ing the fil­ter ele­ments is the most impor­tant event in the main­te­nance of CO.

Con­clu­sion: main­te­nance of the heat­ing sys­tem is a rather com­pli­cat­ed process that requires cer­tain tech­ni­cal knowl­edge and time. The deci­sion on whether to car­ry out these works inde­pen­dent­ly or con­clude an agree­ment with a con­trac­tor can only be made after a thor­ough analy­sis of all the pros and cons.

Choos­ing a con­trac­tor

Heating Service Contractor

Tip: If the own­er decides to involve a third-par­ty com­pa­ny to car­ry out pro­fes­sion­al main­te­nance of the heat­ing and water sup­ply sys­tems of a pri­vate house, then the best option would be to choose the same orga­ni­za­tion that car­ried out the instal­la­tion and com­mis­sion­ing of the CO.

If you have to choose a third-par­ty orga­ni­za­tion, then you should be guid­ed by a few sim­ple rules:

  1. A good, and most impor­tant­ly, respon­si­ble con­trac­tor should not be new to the mar­ket for these ser­vices.
  2. The specifics of work­ing with clients requires the pres­ence of feed­back on the com­pa­ny’s activ­i­ties. The main thing is to deter­mine how they cor­re­spond to real­i­ty. It is quite sim­ple to do this: cus­tom reviews will be 100% pos­i­tive, which is almost impos­si­ble in real life.

A very impor­tant point is the con­clu­sion of a heat sup­ply agree­ment between the cus­tomer and the con­trac­tor, which should pro­vide not only a cer­tain “pack­age” of ser­vices and the tim­ing of their imple­men­ta­tion, but also lia­bil­i­ty in case of untime­ly or incom­plete ful­fill­ment of their oblig­a­tions.

Par­tic­u­lar atten­tion should be paid to the claus­es of the con­tract ded­i­cat­ed to the main­te­nance of the boil­er plant and automa­tion. The manda­to­ry list of activ­i­ties should include the fol­low­ing types of work:

  • Burn­er adjust­ment, main­te­nance, clean­ing and adjust­ment of devices respon­si­ble for prepar­ing the gas-air mix­ture.
  • Check­ing the qual­i­ty of draft and the con­di­tion of the chim­ney.
  • Test­ing, adjust­ment (if nec­es­sary, repair or replace­ment) of devices that are part of the automa­tion and safe­ty group of the boil­er.

Tip: an impor­tant fac­tor in choos­ing a respon­si­ble con­trac­tor is the time at which the team can start per­form­ing work after receiv­ing an appli­ca­tion from the cus­tomer. It is high­ly desir­able that this clause be spelled out in the con­tract.

As not­ed above, the cost of ser­vic­ing a CO depends on its com­plex­i­ty, degree of automa­tion, and ser­vice pack­age.

  • Annu­al main­te­nance with a list of com­mis­sion­ing works — from 8 0 to 150$.
  • One-time repair of a boil­er plant from 1.50 $.
  • Chim­ney clean­ing — from 1 0 to 30$.
  • Elim­i­na­tion of CO tight­ness prob­lems — from 1.20 $.
  • Main­te­nance of heat­ing devices — from 30 $.

You should be aware that after per­form­ing work relat­ed to the main­te­nance of CO, the cus­tomer signs the act of accep­tance of the heat­ing sys­tem.

Based on the fore­go­ing, the cost of CO main­te­nance can be quite impres­sive for the fam­i­ly bud­get. That is why most own­ers per­form some types of work on their own, which is reflect­ed in the con­tract.

Maintenance of the heating system yourself

So, what can you do your­self with­out over­pay­ing for it to spe­cial­ists?

  1. The first is the main­te­nance of radi­a­tors, which includes: mon­i­tor­ing the tight­ness of con­nec­tions, heat dis­tri­b­u­tion over the bat­tery area and check­ing the per­for­mance of shut­off valves. If uneven heat­ing of the radi­a­tor is detect­ed, it is rec­om­mend­ed to remove air locks using Mayevsky cranes.
  2. Elim­i­na­tion of leaks.

These works are per­formed in the fol­low­ing sequence:

  • The move­ment of the coolant in the emer­gency sec­tion is blocked.
  • A frag­ment of neo­prene rub­ber is applied to the dam­aged area, after which the leak site is screed­ed with a pipe clamp.
  • After car­ry­ing out these oper­a­tions, bleed the air that has entered the sys­tem with an air vent on the safe­ty group and through the Mayevsky taps.

Advice: after the leak is elim­i­nat­ed and air is released from the CO, it is nec­es­sary to add the coolant to the sys­tem to the required vol­ume.
