Ther­mostats are used not only with elec­tric under­floor heat­ing. The scope of their appli­ca­tion is quite exten­sive. For exam­ple, these devices have proven them­selves well when work­ing with heat­ing boil­ers. More­over, you can choose the best ther­mo­stat both for an elec­tric boil­er, and for gas and even sol­id fuel. Which mod­els are worth pay­ing atten­tion to in 2022 — in the Kom­so­mol­skaya Prav­da rat­ing.

Rating of the top 4 best thermostats for boilers according to KP

1. Terneo RK 32A

A rel­a­tive­ly rare form fac­tor for ther­mostats is imple­ment­ed in Ter­neo RK 32A. The device is designed for instal­la­tion in switch­boards or, as it is also called, on a DIN rail. The device works with under­floor heat­ing and boil­ers. The con­trol here is elec­tron­ic and is car­ried out using three but­tons. But the tem­per­a­ture set for the boil­er is vis­i­ble on a very sim­ple three-dig­it screen. But its read­abil­i­ty is not bad due to the bright­ness and con­trast. By the way, with the help of RK 32A it is pos­si­ble to con­trol the heat­ing of pipes, pro­tect­ing them from freez­ing. In this mod­el, there is nei­ther remote access nor pro­gram­ming, so the oper­a­tion of the boil­er can only be con­trolled man­u­al­ly.

Pros and cons

Instal­la­tion in the elec­tri­cal pan­el will come in handy for some­one, it works not only with boil­ers, but can also be used in a pipe heat­ing sys­tem
No pro­gram­ming option

2. Caleo C450

An afford­able option for a heat reg­u­la­tor for a warm home. Caleo C450 is designed for sur­face instal­la­tion. The adjust­ment range of the boil­er heat­ing lev­el here is from 10 °C to 35 °C. The con­trol of this mod­el is mechan­i­cal, but with its own specifics. It is clear that they were try­ing to save mon­ey here, but why is there no tem­per­a­ture gra­da­tion around the knob, but only risks? Prob­a­bly the man­u­fac­tur­er was try­ing to save mon­ey. But there are two tem­per­a­ture sen­sors and a self-diag­no­sis mode.

Pros and cons

Inex­pen­sive, water­proof
You will have to guess with the tem­per­a­ture when set­ting, a nar­row adjust­ment range for the boil­er

3. Nest Learning Thermostat 3.0

Nest Learn­ing Ther­mo­stat 3.0. Pho­to: yandex.market.ru

A ther­mo­stat that can work with heat­ing boil­ers, which is very obscene­ly expen­sive. The func­tion­al­i­ty here is so wide that some options seem super­flu­ous. Exter­nal­ly, the ther­mo­stat is a wash­er, which is installed sep­a­rate­ly. The con­nec­tion between the device and the boil­er is wire­less, via Wi-Fi, so Nest must be select­ed for cer­tain mod­els of heat­ing equip­ment. You can con­trol the reg­u­la­tor using the rotary ring or from a mobile appli­ca­tion. Of course, both pro­gram­ming modes and remote con­trol are present here. Among the unusu­al fea­tures are such as auto­mat­ic shut­down if peo­ple leave the premis­es; auto-sched­ul­ing based on user pref­er­ences; autostart when a per­son appears in the room. There may be a prob­lem with the lat­ter, or rather, with the oper­a­tion of the sen­sor — there­fore, the man­u­fac­tur­er rec­om­mends not installing the ther­mo­stat for the boil­er in the far cor­ner.

Pros and cons

An inter­est­ing smart home solu­tion that geeks might like, exten­sive automa­tion
Not suit­able for all heat­ing boil­ers, gigan­tic cost — for this price you can buy sev­er­al excel­lent ther­mostats from oth­er man­u­fac­tur­ers

4. REXANT R200

Rel­a­tive­ly afford­able ver­sion of the ther­mo­stat for the boil­er. Despite this, a large touch screen is used here. The device is installed dis­creet­ly, in the frame of the light switch. R200 can work with both under­floor heat­ing and elec­tric heat­ing boil­er, as well as infrared ele­ments. The device mea­sures the tem­per­a­ture in the room with two sen­sors: inter­nal and remote. There is also pro­gram­ming up to 6 time peri­ods for each day of the week. The man­u­fac­tur­er declared a func­tion when the ther­mo­stat under­stands that the tem­per­a­ture in the sys­tem is high­er than the set tem­per­a­ture, after which the heat­ing stops. Inter­est­ing­ly, although IP20 pro­tec­tion against dust and mois­ture is declared here, users com­plain that the device is still afraid of water ingress. There is also mar­riage, when the device fails in just six months.

Pros and cons

Touch con­trol, dual-zone meter­ing
Mois­ture pro­tec­tion only on paper, mar­riage occurs

How to choose a thermostat for boilers

The desire to be inde­pen­dent of the capri­cious cen­tral heat­ing sys­tem is under­stand­able. Yes, and you can save a lot on util­i­ty bills if you get the oppor­tu­ni­ty to man­age the process your­self. But assem­bling your sys­tem based on a boil­er is not so sim­ple. About how to choose a ther­mo­stat, togeth­er with Kom­so­mol­skaya Prav­da will tell Vitaly Nesterenko, heat­ing equip­ment deal­er

Why does the boiler need a thermostat

So, you have decid­ed to install a heat­ing boil­er, for exam­ple, elec­tric or gas. Now you need to learn how to use it cor­rect­ly. It is for this that a ther­mo­stat is built into the sys­tem. So, with this device, the equip­ment turns on when the tem­per­a­ture drops below the set one, or turns off when the desired ther­mal mark is reached. The best ther­mostats for boil­ers allow you to set the heat­ing sys­tem to work when the tem­per­a­ture is 4–5 ° C low­er if you are not at home. It would seem, what is 4°C? In fact, such a mea­sure will reduce heat­ing costs by up to 30%.

What are

Some boil­ers imme­di­ate­ly come with a built-in ther­mo­stat. Such sys­tems have a num­ber of lim­i­ta­tions and often flaunt an inflat­ed price tag. Third-par­ty ther­mostats are mechan­i­cal, elec­tron­ic and touch. With the first, every­thing is sim­ple — an on / off key and a rotary but­ton to con­trol the tem­per­a­ture. In elec­tron­ic ther­mostats, the con­trol is already thin­ner and there is a pro­gram­ma­ble mode in which you can set the time, switch-on date or a repeat­able dai­ly mode. The most advanced are sen­so­ry. They have a con­trol that is under­stand­able to a mod­ern user, and often remote con­trol via the Inter­net and a smart­phone.

Final­ly, among the best ther­mostats for boil­ers, you can find both wired and wire­less mod­els. With the first it is clear — they are phys­i­cal­ly con­nect­ed to the boil­er. It is sim­ple and reli­able, but already dur­ing the instal­la­tion process, the wires need to be laid some­where. Wire­less ther­mostats have recent­ly come into use. Con­trol is by means of radio sig­nal trans­mis­sion. That is, one block is mount­ed in close prox­im­i­ty to the heat­ing boil­er, con­nect­ed to the equip­ment ter­mi­nals. The sec­ond node is placed at the ther­mo­stat. This is real­ly con­ve­nient, but there may be inter­fer­ence between the receiv­er and trans­mit­ter.

Temperature controllers for gas and electric boilers

Not all ther­mostats are suit­able for both gas and elec­tric­i­ty. There are much more mod­els for the sec­ond type of boil­ers, because, in fact, the prin­ci­ple of oper­a­tion is almost the same as that of elec­tric floors, only the pow­er is high­er. With gas, for obvi­ous rea­sons, every­thing is some­what more com­pli­cat­ed. For such heat­ing boil­ers, I rec­om­mend choos­ing wire­less mod­els (this way we min­i­mize the risk of a short cir­cuit) and, at least, with a pro­gram­ma­ble oper­at­ing mode. The lat­ter allows you to seri­ous­ly save the resource of gas equip­ment.

Remote control

It is most con­ve­nient to live with heat­ing equip­ment if a ther­mo­stat is con­nect­ed to it with the pos­si­bil­i­ty of remote con­trol. To do this, it must have Wi-Fi, and the house must have Inter­net access. Even bet­ter, if the man­u­fac­tur­er of the ther­mo­stat also offers a pro­gram for a smart­phone, from which you can con­trol the heat from any­where, as long as there is a mobile con­nec­tion. Then you can achieve max­i­mum effi­cien­cy of the heat­ing boil­er.
