Heat meters for heating in an apartment: types, installation


Heat meter

No one doubts the need to install water and elec­tric­i­ty meters.

And the point is not only in leg­is­la­tion, but also in real sav­ings and the desire to pay for what was used.

Every year more and more apart­ment own­ers come to the idea of ​​installing a heat meter, because the heat­ing fee affects the fam­i­ly bud­get.

Working principle and advantages

An apart­ment heat meter is a small device that is built into a heat­ing pipe and records only the heat that was actu­al­ly con­sumed.

The device reg­is­ters 3 indi­ca­tors:

  • coolant vol­ume (hot water) that the con­sumer received;
  • inlet tem­per­a­ture to the inter­nal heat­ing sys­tem;
  • tem­per­a­ture coolant at the exit from the apart­ment.

Based on these data, the heat meter gives the main val­ue — heat con­sump­tion. It is mea­sured in gigacalo­ries spent in the billing peri­od: a month, a year or even a day.

As a result, the con­sumer does not pay for heat loss­es at the time of trans­porta­tion along the high­ways to the house and apart­ment.

The most prof­itable option is to install a meter togeth­er with a ther­mo­stat. In this case, you will not have to pay for excess heat, which the res­i­dents do not need, which often hap­pens, for exam­ple, dur­ing thaws.

Use of heat meters allows you to save up to 50% on heat­ingwhich is a sig­nif­i­cant amount.

But for a real effect, you must install the device cor­rect­ly.

Heat meter mounting options and possible difficulties

Heat meter for heating batteryHeat­ing sys­tems of all apart­ments can be clas­si­fied into 2 groups:

  • ver­ti­cal type in which almost every radi­a­tor has its own ris­er;
  • hor­i­zon­tal an option that has one com­mon ris­er, from which a net­work of hor­i­zon­tal pipelines diverges to the bat­ter­ies.

The first type is typ­i­cal for hous­es of old con­struc­tion. In such a sys­tem, the instal­la­tion of a heat meter is com­plex and expen­sive. After all, you will have to install such a con­trol device for each ris­er, which is unprof­itable and pro­hib­it­ed in mul­ti-storey and apart­ment build­ings by Order of the Min­istry of Region­al Devel­op­ment of Europe dat­ed Decem­ber 29, 2011 No. 627.

In this case, you can install a heat­ing cost dis­trib­u­tor on each radi­a­tor. The prin­ci­ple of their oper­a­tion is to mea­sure the dif­fer­ence between the tem­per­a­tures of the bat­tery and the room. Indi­ca­tions for the apart­ment are sum­ma­rized. You can also col­lec­tive­ly install a com­mon house meter with the whole house. The cost of it will be divid­ed among the res­i­dents, so it will be insignif­i­cant, as well as the eco­nom­ic effect.

The sit­u­a­tion is much sim­pler with a hor­i­zon­tal heat­ing sys­tem.char­ac­ter­is­tic of new high-rise build­ings. In this case, the heat meter is mount­ed in a pipe that sup­plies heat to the apart­ment. Less often, the sen­sor is placed on the return pipeline.

If your apart­ment has a sec­ond type of heat­ing sys­tem, then the heat meter will help save mon­ey and pay off quick­ly enough. It remains only to decide on the type of device.

Heat meters for heating in an apartment: types of devices

When choos­ing a heat meter, it is nec­es­sary to focus not only on the price, but also on the con­di­tions in which the device will oper­ate. Accord­ing to the prin­ci­ple of oper­a­tion, sev­er­al types of heat meter­ing devices are dis­tin­guished.

Mechanical meters for heating batteries

Mechanical counter per batteryDevices with a mechan­i­cal prin­ci­ple of oper­a­tion are also called tacho­me­t­ric. They can be of three types:

  • screw;
  • tur­bine;
  • wedge-shaped.

In cen­tral­ized heat­ing sys­tems, hot water is used as a heat car­ri­er. It is its quan­ti­ty that entered the in-house heat­ing sys­tem that takes into account the mech­a­nism itself.

For all heat meters of this type there are sev­er­al com­mon dis­ad­van­tages:

  • they are short-lived;
  • not par­tic­u­lar­ly accu­rate at low coolant flow;
  • sen­si­tive to the pres­ence of sus­pen­sions in the water, which is solved with a sim­ple strain­er;
  • not suit­able for hard water.

By cost tacho­me­t­ric devices the cheap­est. One of the most pop­u­lar is the ELF device, man­u­fac­tured in Poland. It con­sists of a tem­per­a­ture sen­sor, a tacho­me­t­ric meter and an elec­tric cal­cu­la­tor. On aver­age, the coun­ters of this com­pa­ny cost 80–90$.

Also, often for apart­ments they buy the ST-10 device, which, depend­ing on the desire of the con­sumer, can be equipped with a tacho­me­t­ric, ultra­son­ic or elec­tro­mag­net­ic flow meter. In addi­tion, the counter includes a cal­cu­la­tor and a ther­mo­cou­ple. Such devices cost about 90–100$.

Electromagnetic heat meters

Electromagnetic heat meterWhen water pass­es through a mag­net­ic field, an elec­tric cur­rent is gen­er­at­ed. This phe­nom­e­non under­lies the oper­a­tion of elec­tro­mag­net­ic heat meters. Such devices work with high accu­ra­cy when prop­er­ly con­nect­ed.

Fail­ures can occur for sev­er­al rea­sons:

  • for­ma­tion of an oxi­da­tion film on the con­tact sur­face;
  • impu­ri­ties in water;
  • exter­nal elec­tro­mag­net­ic field.
  • Their dis­ad­van­tage is the high price.

In addi­tion to ST-10 meters with a VSE-BI flow meter, the VOICE ТСР‑M devices in the ver­sion ТСР-033 or ТСР-034 with a VOICE ER flow meter oper­ate on the elec­tro­mag­net­ic prin­ci­ple. The cost of this device is at least 320 $.

Vortex counters for heat

Vortex counterIn these devices, the flow rate is tak­en into account on the basis of the analy­sis of vor­tices that are formed when water and even steam pass through obsta­cles. Indi­ca­tions can be dis­tort­ed:

  • air bub­bles;
  • large sus­pen­sions;
  • rec­on­cil­i­a­tion errors.

It is rec­om­mend­ed to install a mesh fil­ter. Water hard­ness and limescale in the sys­tem do not affect the qual­i­ty of work. The most pop­u­lar vor­tex counter is the Com­pact T‑21. It costs from 90 $.

Ultrasonic devices and prices

The prin­ci­ple of oper­a­tion of this device is based on mea­sur­ing the speed of pas­sage of ultra­sound through a liq­uid stream.

There are 4 types of ultra­son­ic devices:Ultrasonic metering device

  • tem­po­rary;
  • fre­quen­cy;
  • cor­re­la­tion;
  • Doppler.

Sev­er­al dis­tort the tes­ti­mo­ny can:

  • scale in water;
  • scale in the coolant;
  • air bub­bles.

But these are by far the most durable, accu­rate and reli­able sys­tems. The fol­low­ing ultra­son­ic meters are wide­ly used in apart­ments:

  • Mul­ti­cal 402 an aver­age cost of 500 euros;
  • Ultra­heat T230the price of which is at least 15,5 dol­lars;
  • Ther­mal ener­gy meter Individual‑1 for ver­ti­cal heat­ing dis­tri­b­u­tion - from 15$.

It is pos­si­ble to deter­mine the type of device only after con­sult­ing with spe­cial­ists. Any of the meters must be pro­vid­ed with spe­cial doc­u­men­ta­tion.

Registration, verification and transfer of testimony

How to install a heat meter?The instal­la­tion of a heat meter­ing device can only be car­ried out by spe­cial­ists from an orga­ni­za­tion that has spe­cial doc­u­men­ta­tion autho­riz­ing such activ­i­ties. The entire instal­la­tion process is car­ried out in sev­er­al steps.

Step 1. Draw­ing up project doc­u­men­ta­tion.

Step 2 Sub­mis­sion of the project to the orga­ni­za­tion sup­ply­ing your home with heat.

Step 3 Instal­la­tion of the counter and its sub­se­quent reg­is­tra­tion.

Step 4 Final adjust­ment of the oper­a­tion of the device and its trans­fer to the oper­a­tion of a com­pa­ny engaged in the super­vi­sion of such devices.

After that, the counter can be used. Its oper­a­tion includes trans­mis­sion of tes­ti­mo­ny. This pro­ce­dure can be car­ried out in sev­er­al ways:

  • to the e‑mail of the man­ag­ing orga­ni­za­tion;
  • by phone;
  • an entry in the receipt with an inde­pen­dent cal­cu­la­tion of the amount of pay­ment.

The cost of installing a heat meterMain­te­nance of the device con­sists in time­ly ver­i­fi­ca­tion. The new meter is ver­i­fied at the fac­to­ry, and the con­sumer receives it with a record, a stick­er and a stamp in the pass­port and on the device itself.

The reg­u­lat­ed time between ver­i­fi­ca­tions is 3–5 years. The device is re-ver­i­fied at a branch of Ros­test, at a spe­cial orga­ni­za­tion or at the man­u­fac­tur­ing plant itself.

The price of installing a heat meter for heating in an apartment

If you decide to install a heat meter, you must choose the right com­pa­ny to which you entrust this impor­tant event.

A reli­able com­pa­ny can be deter­mined by sev­er­al para­me­ters:

  • cer­ti­fi­ca­tion and admis­sion to such work;
  • free vis­it of a spe­cial­ist for con­sul­ta­tion;
  • pro­vid­ing guar­an­tees for work;
  • ser­vice main­te­nance.

The instal­la­tion price is on aver­age 50 dol­lars.
