best wall and floor models

Due to the fact that most coun­try hous­es in Euro­pean cities and towns are not equipped with cen­tral heat­ing, the issue of heat­ing a home is quite acute. Gas heat­ing sys­tems quite eas­i­ly solve the issue of cre­at­ing autonomous heat­ing. If an elec­tric water heater is installed in the house, then the best solu­tion would be.

Today, the Euro­pean cli­mate tech­nol­o­gy mar­ket is over­flow­ing with heat­ing sys­tems from man­u­fac­tur­ers from Ger­many, Italy, France, Slove­nia and Chi­na. In terms of its char­ac­ter­is­tics, domes­tic equip­ment is not infe­ri­or to the lead­ers of this seg­ment and is on a par with such brands as Bosch, Vail­lant, Baxi, etc. Even a spe­cial­ist can get con­fused in a huge num­ber of mod­els, man­u­fac­tur­ers, brands. That is why the domes­tic con­sumer is increas­ing­ly ask­ing the ques­tion, which gas sin­gle-cir­cuit boil­er is bet­ter?

Criterias of choice

Choosing the right boiler model

To choose the right mod­el of a heat­ing boil­er, you should have an idea about the design and prin­ci­ple of oper­a­tion of the device. If there is no such knowl­edge, then con­tact the experts. If you imag­ine how sin­gle-cir­cuit gas instal­la­tions are arranged, then before choos­ing a par­tic­u­lar mod­el, pay atten­tion to the fol­low­ing points and design fea­tures:

  1. Man­u­fac­tur­er. Man­u­fac­tur­ers from Ger­many (Bosch, Vail­lant) are lead­ing in the pro­duc­tion of reli­able gas heat­ing instal­la­tions. The most func­tion­al sin­gle-cir­cuit boil­er units are offered by man­u­fac­tur­ers from South Korea (NAVIEN), Slove­nia (Protherm). Ital­ian man­u­fac­tur­ers offer devices with the best com­bi­na­tion of price and qual­i­ty (Baxi and Fer­rol­li).
  2. Igni­tion type. In mod­ern heat­ing boil­ers, you can find elec­tron­ic and piezo igni­tion. The first type — involves the igni­tion of the gas mix­ture in auto­mat­ic mode. In the sec­ond, bat­ter­ies are used as a pow­er plant. Igni­tion requires human inter­ven­tion.
  3. Burn­er. Sin­gle-cir­cuit boil­ers use sin­gle-stage and mod­u­lat­ing burn­ers. Sin­gle stage always run at 100% pow­er. Mod­u­lat­ed — more mod­ern, allow you to change the heat­ing pow­er of the coolant in the range from 30 to 100%. In addi­tion, the burn­er can be atmos­pher­ic or tur­bocharged. Atmos­pher­ic — more hardy and silent. Tur­bocharged — have a high­er effi­cien­cy, but also cost sig­nif­i­cant­ly more.
  4. heat exchang­er mate­r­i­al. For the heat exchang­er, a mate­r­i­al with good ther­mal con­duc­tiv­i­ty and resis­tance to high tem­per­a­tures is select­ed. Cop­per is a mate­r­i­al with bet­ter ther­mal con­duc­tiv­i­ty and a low melt­ing point. A boil­er with a cop­per heat exchang­er should be select­ed with a low pow­er equip­ment. In addi­tion to cop­per, stain­less steel is used for coils, which is char­ac­ter­ized by aver­age ther­mal con­duc­tiv­i­ty and dura­bil­i­ty. Cast iron heat exchang­ers are durable, but due to their high weight they are used only in floor mod­els.
  5. The com­bus­tion cham­ber. Mod­ern boil­ers are equipped with an open or closed com­bus­tion cham­ber. In the open, the air intake comes from the room, in the closed, the air comes from the street through a coax­i­al chim­ney.
  6. Removal of com­bus­tion prod­ucts. Exhaust gas­es are removed in mod­ern heat­ing boil­ers using nat­ur­al and forced draft. In the first case, a ver­ti­cal chim­ney and good ven­ti­la­tion in the room with the boil­er are required. In the sec­ond option, com­bus­tion prod­ucts are removed through a coax­i­al chim­ney using a built-in fan.

In order to pro­vide assis­tance, a rat­ing of heat­ing instal­la­tions was com­piled, based on oper­a­tional char­ac­ter­is­tics, design fea­tures and reviews of real own­ers.
