Adjustment of a warm water floor

[ad_1]

Like any heat­ing sys­tem, a water heat­ed floor requires the instal­la­tion of spe­cial equip­ment that allows you to adjust the oper­a­tion of the heat­ing com­plex. Unlike the old tra­di­tion­al heat­ing meth­ods using a cen­tral­ized com­mu­ni­ca­tion sys­tem, the new equip­ment is much more effi­cient, but requires more atten­tion. The heat­ing of the coolant for a warm water floor, car­ried out by autonomous boil­ers, must always be car­ried out under the con­trol of mea­sur­ing equip­ment. Oth­er­wise, you can for­get about the com­fort­able tem­per­a­ture inside the heat­ed room, and the safe­ty of such heat­ing will be sig­nif­i­cant­ly reduced.

Issues relat­ed to the man­age­ment and adjust­ment of under­floor heat­ing are becom­ing rel­e­vant today. The rea­son for the increased inter­est of con­sumers in this top­ic is due to the fact that in most cas­es, the own­ers of new homes pre­fer a heat­ing floor as a com­plete inte­grat­ed heat­ing sys­tem. Adjust­ing the heat­ing tem­per­a­ture of a warm water floor allows you to make the heat­ing sys­tem in the house flex­i­ble and dynam­ic, adapt­ed to the real cli­mat­ic sit­u­a­tion.

The process of con­trol­ling heat­ing equip­ment in a res­i­den­tial build­ing is not asso­ci­at­ed with any spe­cial manip­u­la­tions and com­plex equip­ment. Even such a large-scale heat­ing sys­tem as warm water floors is con­trolled by reg­u­la­tors, devices that react to the slight­est tem­per­a­ture changes, in the pipeline and in the room. For under­floor heat­ing, adjust­ment con­sists in the cor­rect set­ting of devices and devices involved in the oper­a­tion of the heat­ing sys­tem. Let us con­sid­er in detail which reg­u­la­tors take place in this case, what is the prin­ci­ple of oper­a­tion of each device and how the instal­la­tion is car­ried out.

The meaning and place of regulators for water floors

Let’s imme­di­ate­ly dot all the “i” to indi­cate the impor­tance of the infor­ma­tion described in this arti­cle. Floor heat­ing is a low-tem­per­a­ture heat­ing sys­tem, which will only be effi­cient and effec­tive when it is equipped with ther­mostats. Even the sim­plest ver­sion of heat­ing with water cir­cuits laid in the floor involves the instal­la­tion of con­trol valves on both parts of the man­i­fold. By man­u­al­ly turn­ing the valve heads, you can achieve an increase or decrease in the vol­ume of hot coolant sup­plied to the water loops of under­floor heat­ing. The only dis­ad­van­tage of this method of adjust­ment is the set­ting on a whim.

By giv­ing pref­er­ence to man­u­al con­trol, you will have to focus on your own feel­ings. More­over, the desired result will not come imme­di­ate­ly. Warm floors with man­u­al con­trol — iner­tial sys­tem. Man­u­al­ly adjust­ing the tem­per­a­ture of the coolant for a water-heat­ed floor will require you to be con­stant­ly present, react­ing to cli­mate changes out­side the win­dow. Sig­nif­i­cant assis­tance in the adjust­ment process is pro­vid­ed by flow meters, small and com­pact devices that con­trol the vol­ume of flu­id sup­plied to the water cir­cuit.

On a note: Hav­ing both rotame­ters (flowme­ters) and con­trol valves at your dis­pos­al, you can achieve a com­fort­able tem­per­a­ture in one room, at a cer­tain point in the “con­stant” type.

For exam­ple: you are inter­est­ed in heat­ing the bath­room. This is a room in which there is always high humid­i­ty and a warm tiled floor will be an appro­pri­ate attribute. It is enough to adjust the devices once or twice and there will be a com­fort­able tem­per­a­ture in the bath­room, which does not depend on weath­er con­di­tions.

For ref­er­ence: Accord­ing to users, the mechan­i­cal method of adjust­ment can cause air locks in the pipes of the heat­ing cir­cuits. Air­ing occurs as a result of a sharp change in the work­ing pres­sure and tem­per­a­ture of the coolant that occurs dur­ing man­u­al con­trol.

Anoth­er thing is the automa­tion of under­floor heat­ing. In this case, you will have to spend mon­ey on the pur­chase of elec­tro-mechan­i­cal and elec­tron­ic devices. Such devices can solve sev­er­al prob­lems at once, depend­ing on the method of con­trol­ling heat­ing equip­ment. Ther­mostats and ser­vo dri­ves allow you to autonomous­ly con­trol not only the tem­per­a­ture of indoor air heat­ing, but also the degree of heat­ing of the floor sur­face. The tem­per­a­ture of the under­floor heat­ing is a deci­sive fac­tor in the effec­tive­ness of under­floor heat­ing, how the reg­u­la­tion is car­ried out, and thus the sys­tem works.

Ther­mostats are lock­ing devices, while ser­vos per­form spe­cif­ic actions. Ther­mostats can be installed sep­a­rate­ly in each room, on the main units and assem­blies of ser­vice equip­ment. Ser­vo dri­ves are indi­vid­ual devices designed to serve one water heat­ing cir­cuit. Com­pat­i­ble with ther­mostats, ser­vo dri­ves, on com­mand, reg­u­late the sup­ply of coolant to the pipeline.

Temperature controllers — types of devices

The water floor is a rather sen­si­tive sys­tem. The degree of heat­ing of the heat car­ri­er, the rate of water sup­ply to the heat­ing cir­cuit and the inten­si­ty of the cir­cu­la­tion of the heat car­ri­er are the para­me­ters that deter­mine the heat­ing effi­cien­cy.

From a tech­ni­cal point of view, tem­per­a­ture con­trollers are devices that ensure the per­for­mance of cer­tain mechan­i­cal actions as a result of a reac­tion to changes in the spec­i­fied tem­per­a­ture para­me­ters. Tem­per­a­ture con­trollers solve the fol­low­ing tasks:

  • auto­mat­ed switch­ing on and off of the heat­ing sys­tem;
  • con­trol and main­te­nance of the set tem­per­a­ture inside the room;
  • pro­gram­ma­ble devices pro­vide the inclu­sion of heat­ing at a cer­tain time;
  • con­trol over the degree of heat­ing of the coolant pro­vides ener­gy sav­ings.

On a note: in prac­tice, it has been noticed more than once that installing and con­fig­ur­ing a ther­mo­stat in a room for under­floor heat­ing allows you to save up to 20–30% of the blue fuel con­sumed for the oper­a­tion of an autonomous boil­er.

In prac­tice, the fol­low­ing mod­els of reg­u­la­tors are used:

mechan­i­cal devices. This cat­e­go­ry of devices belongs to bud­get options. A dis­tinc­tive fea­ture of mechan­i­cal reg­u­la­tors is their reli­a­bil­i­ty and easy main­te­nance. Adjust­ment is car­ried out by sim­ply turn­ing the dial, which is set to a cer­tain scale val­ue. In some cas­es, the front of the device has a mechan­i­cal lever that oper­ates on the open / closed prin­ci­ple. In addi­tion to mon­i­tor­ing the tem­per­a­ture of the coolant in the sup­ply pipe, such devices are not designed to per­form oth­er func­tions.

Elec­tron­ic devices have the same func­tions, only dif­fer in the way they are imple­ment­ed. The device is equipped with a screen and has but­tons with which the adjust­ment is car­ried out. The instru­ment dis­plays real-time para­me­ters and pro­gram­ma­ble data. Push-but­ton con­trol allows you to set the spec­i­fied para­me­ters and car­ry out a grad­ual change in tem­per­a­ture.

On a note: elec­tron­ic devices for adjust­ing under­floor heat­ing cost three to five times more than mechan­i­cal devices.

Among elec­tron­ic con­trol devices, pro­gram­ma­ble devices occu­py a spe­cial place. The pres­ence of soft­ware cre­ates the con­di­tions for main­tain­ing the tem­per­a­ture of floor heat­ing, the tem­per­a­ture regime inside the room in real time and not only. The spec­i­fied tem­per­a­ture para­me­ters and time allow you to change the tem­per­a­ture of under­floor heat­ing over time, adjust the oper­a­tion of all units and assem­blies of the under­floor heat­ing, depend­ing on cli­mat­ic con­di­tions.

Such func­tions are very con­ve­nient, free­ing up a lot of time for the inhab­i­tants of the house. With the help of pro­gram­ma­ble devices, you can ensure the oper­a­tion of the heat­ing sys­tem in your absence, main­tain­ing a sta­ble and com­fort­able tem­per­a­ture in the house. Sav­ing ener­gy resources when using pro­gram­ma­ble elec­tron­ic con­trollers is 25–30%. In mod­ern con­di­tions, when com­fort­able hous­ing is gain­ing pop­u­lar­i­ty, pro­gram­ma­ble con­trollers are becom­ing in demand. Such sys­tems can be con­trolled via mobile devices, remote­ly. Solv­ing sev­er­al tasks in a com­plex at once, adjust­ing the tem­per­a­ture of heat­ing the floor sur­face and con­trol­ling the air tem­per­a­ture inside the room, elec­tron­ic pro­gram­ma­ble devices are ben­e­fi­cial in all options. Even tak­ing into account the fact that the cost of these devices is quite high.

Eval­u­at­ing the types used in the adjust­ment of under­floor heat­ing, appli­ances, we can draw some con­clu­sions. In each indi­vid­ual case, one should start from what tasks the reg­u­la­tor should solve.

The principle of operation of regulators

*

The most wide­ly used electro­mechan­i­cal devices. These devices suc­cess­ful­ly com­bine elec­tron­ics and mechan­i­cal parts. At a cost, such devices are much cheap­er than elec­tron­ic ana­logues. The design and prin­ci­ple of oper­a­tion of electro­mechan­i­cal ther­mostats is quite sim­ple and under­stand­able.

Elec­tron­ics in this regard is quite expen­sive equip­ment. How­ev­er, in terms of their effi­cien­cy, such devices are much more effi­cient and more con­ve­nient to use.

In order to make the right choice — to give pref­er­ence to man­u­al con­trol or to focus on automa­tion, you should under­stand the prin­ci­ple of oper­a­tion of the reg­u­la­tors.

The main task that is assigned to the reg­u­la­tors in the sys­tem of warm water floors is the man­age­ment of tech­no­log­i­cal process­es. The prin­ci­ple of oper­a­tion of the devices is deter­mined by the degree of use and oper­a­tion of under­floor heat­ing in res­i­den­tial premis­es. The design of the device can be par­tial­ly auto­mat­ed or ful­ly auto­mat­ed.

Accord­ing to the prin­ci­ple of oper­a­tion, the reg­u­la­tors are respec­tive­ly divid­ed into man­u­al devices and auto­mat­ed ones. The first are con­ven­tion­al shut-off valves. It is with their help that you can stop or resume the sup­ply of coolant to the under­floor heat­ing pipeline. The scope of such devices is small heat­ed rooms. Ther­mo­sta­t­ic reg­u­la­tors, devices of a much more com­plex design. Accord­ing to the prin­ci­ple of oper­a­tion, such prod­ucts are sim­i­lar to man­u­al mech­a­nisms, how­ev­er, a spe­cial elec­tron­ic sen­sor is pro­vid­ed in the design. Any change in tem­per­a­ture from the set para­me­ters acti­vates the cir­cu­la­tion pump, which pro­vides hot water. The device oper­ates in accor­dance with a giv­en pro­gram, com­plete­ly tak­ing over the main stages of con­trol­ling a warm floor.

Mod­ern elec­tron­ic ther­mostats have exten­sive func­tion­al­i­ty that pro­vides the abil­i­ty to con­trol one water cir­cuit or pro­vide con­trol over the oper­a­tion of sev­er­al under­floor heat­ing pipes at once. Thanks to the embed­ded soft­ware, such devices are able to respond to changes in cli­mat­ic con­di­tions, cre­at­ing com­fort­able tem­per­a­ture con­di­tions for the inhab­i­tants of a res­i­den­tial facil­i­ty.

Conclusion

In order for the warm floor to work effec­tive­ly, and you are sat­is­fied with high-qual­i­ty heat­ing, it is nec­es­sary not only to have reg­u­la­tors built into the com­plex of con­trol and mea­sur­ing equip­ment, but also their set­ting is impor­tant. With mechan­i­cal devices, the sit­u­a­tion is clear. Hav­ing an idea of ​​​​the prin­ci­ple of oper­a­tion of mech­a­nisms, hav­ing the appro­pri­ate skills, you can con­fig­ure such devices your­self.

With elec­tron­ic and pro­gram­ma­ble devices a lit­tle more dif­fi­cult. Here it is bet­ter to turn to the ser­vices of spe­cial­ists who will be able to cor­rect­ly set up auto­mat­ic floor heat­ing through­out the house.
