Wall-mounted gas heating boiler: which is better, prices

[ad_1]

Wall mounted gas boilers

The Euro­pean gasi­fi­ca­tion pro­gram has made blue fuel more acces­si­ble. There­fore, when choos­ing heat­ing sys­tems, the gas ver­sion becomes more prefer­able.

Gas heat­ing wins in many ways: econ­o­my, price, ease of main­te­nance.

The heart of the sys­tem — the boil­er — has wall and floor options, which makes its instal­la­tion the most ver­sa­tile.

Floor or wall?

When choos­ing an option for the loca­tion of a gas heater, the area of ​​u200bu200bthe room is a pri­or­i­ty aspect. Wall-mount­ed boil­ers are effec­tive for pri­vate hous­es or apart­ments with an area of ​​up to 250 m2.

The wall mount­ed option is very ben­e­fi­cial. It does not require a sep­a­rate room, but only a min­i­mum space on the wall.

Instal­la­tion of the wall-mount­ed device is very sim­ple, which sig­nif­i­cant­ly reduces the cost of instal­la­tion work. In addi­tion, the attrac­tive design and uncom­pli­cat­ed oper­a­tion make it par­tic­u­lar­ly advan­ta­geous.

Types of gas boilers

German home appliance by VaillantIn addi­tion to the loca­tion method, boil­ers are divid­ed into oth­er types.

The com­bus­tion cham­ber: open or closed. The first option is prefer­able if there is a chim­ney in the house. If not, then you need a device with a closed com­bus­tion cham­ber. The fan sucks in air from the street, and removes gas­es through a coax­i­al chim­ney built into the wall.

Igni­tion can be of two types: elec­tric and piezo­elec­tric.

  • Elec­tric. This is the most eco­nom­i­cal type of igni­tion. It does not require an ignit­er with a con­stant­ly burn­ing flame, which leads to exces­sive gas con­sump­tion. Sav­ings can be up to 100 liters per year. There is one more advan­tage: if there was a pow­er out­age, then when it is sup­plied, the device will start up on its own.
  • Piezo igni­tion. It involves man­u­al acti­va­tion, which makes it less effec­tive.

Depend­ing on the required fea­tures, boil­ers There are sin­gle and dou­ble loops.

  • Sin­gle-cir­cuit. Designed exclu­sive­ly for space heat­ing. The oper­a­tion of such units is ensured by con­nect­ing to a stor­age water heater.
  • Dou­ble-cir­cuit. These devices per­form two func­tions: heat­ing and hot water sup­ply (DHW). They are more com­plex struc­tural­ly and more diverse in con­fig­u­ra­tion.

Heat exchang­ers serve to trans­fer the heat obtained from the com­bus­tion of fuel to the coolant. They can be of two types:

  • Sep­a­rate. Con­sist of pri­ma­ry and sec­ondary heat exchang­ers. The first trans­fers the heat of the burnt fuel to the coolant. The sec­ond is designed to exchange heat between the coolant and run­ning water.
  • Bither­mic. This is a com­bi­na­tion in one block of two main func­tions: heat­ing and hot water.

Principle of operation

Wall-mounted gas appliance in the kitchenThe oper­a­tion algo­rithm of a sin­gle-cir­cuit boil­er is quite sim­ple. The coolant heat­ed by the burn­er enters the heat­ing sys­tem. The cir­cu­la­tion pump oper­ates con­tin­u­ous­ly.



Dou­ble-cir­cuit cre­ate heat­ing and hot water sup­ply. At the same time, the type and pow­er of the device assume the sup­ply of hot water to one or two points of intake. When hot water is drawn in, heat­ing oper­a­tion is auto­mat­i­cal­ly stopped.

If two sam­pling points are sup­posed, it is bet­ter to install the device at an equal dis­tance from them. This will reduce the wait­ing time for hot water.

When choos­ing a gas unit, the main points are tak­en into account:

  • the required vol­ume of hot water;
  • vol­ume and pow­er of the device;
  • type of heat­ing sys­tem;
  • price;
  • com­fort;
  • equip­ment man­u­fac­tur­er.

The required pow­er is cal­cu­lat­ed very sim­ply. It is nec­es­sary to sum­ma­rize the area of ​​u200bu200ball rooms that need to be heat­ed, and divide the result by 10. For exam­ple, with an area of ​​​​200 m2 the required pow­er of the device must be at least 20 kW. But it is bet­ter to take equip­ment with para­me­ters that slight­ly exceed the cal­cu­la­tions.

An impor­tant fac­tor is pow­er sup­ply sta­bil­i­ty. Devices of Euro­pean man­u­fac­tur­ers react neg­a­tive­ly to pow­er surges. This requires the use of volt­age sta­bi­liz­ers.

Site selection and designSelect­ing an instal­la­tion site is an impor­tant point. If for floor-stand­ing devices the equip­ment of a sep­a­rate room is con­sid­ered ide­al, then wall-mount­ed devices do not require this.

Dimen­sions and design mod­ern wall-mount­ed boil­ers allow you to strength­en them any­where. But the best place for this is the kitchen, bath­room or hall­way. The loca­tion of the device in an unheat­ed room will lead to heat loss, exces­sive gas con­sump­tion.

The walls of a pri­vate house, which retain heat well, make heat­ing the most effi­cient. And this allows you to choose a less pow­er­ful unit, which saves mon­ey.

In addi­tion to coun­try hous­es, it is quite pos­si­ble to install wall-mount­ed boil­ers in apart­ments. This can improve the heat­ing of your apart­ment, with­out depend­ing on the whims of hous­ing and com­mu­nal ser­vices work­ers.

The best manufacturers and prices for gas boilers

Man­u­fac­tur­ers of gas equip­ment are focused on all con­sumers. It is pos­si­ble to pick up heat­ing devices of any firms in rea­son­able prices.

Ger­man and Ital­ian com­pa­nies are con­sid­ered lead­ers in the pro­duc­tion of gas equip­ment. – Vail­lant, Bosch, Viess­mann, Beretta, Baxi.

Ger­man­ic qual­i­ty has always been val­ued. 20 years of unin­ter­rupt­ed oper­a­tion for Ger­man gas equip­ment is con­sid­ered the norm. Ele­ments of heat exchang­ers are cop­per, cov­ered with pro­tec­tive oxide films. The dimen­sions of the boil­ers are com­pact, and the exter­nal design allows them to fit into any design con­fig­u­ra­tion. The effi­cien­cy of such units is very high — 90–93%, and the assem­bly is of high qual­i­ty.

Review:

In 2010, he installed in a house with an area of ​​​​slight­ly more than 180 m2 Ger­man boil­er Vail­lant with an open com­bus­tion cham­ber, 24 kW. In tan­dem with him, he installed a volt­age sta­bi­liz­er Calm.
In the first win­ter, the house stood with­out exter­nal insu­la­tion and the instal­la­tion worked almost at full capac­i­ty, con­stant­ly main­tain­ing the tem­per­a­ture up to 90 degrees. The device with­stood the test with dig­ni­ty, though the gas bills were huge.

A cou­ple of years ago there were pres­sure surges in the sys­tem, it turned out that the expan­sion tank was leak­ing. Was replaced under war­ran­ty. But in gen­er­al, there are no prob­lems with the oper­a­tion, once a year I clean the com­bus­tion cham­ber with a vac­u­um clean­er and drain the water from the cir­cuits.

Ital­ian the devices are prac­ti­cal­ly in no way infe­ri­or to the Ger­man ones. Baxi fifth gen­er­a­tion appli­ances are equipped with atmos­pher­ic burn­ers, which makes their oper­a­tion almost silent.

Location of the wall-mounted boilerKore­an devices are infe­ri­or to Euro­pean ones, but they have a built-in volt­age reg­u­la­tor.

Patri­ot­ic equip­ment can­not yet be com­pared in qual­i­ty with Ger­man or Ital­ian equip­ment, but it is unpre­ten­tious and prefer­able in terms of price.

ISHMA BSK units are non-volatile. This makes them resis­tant to pow­er out­ages. But to cre­ate a heat­ing sys­tem, they need to buy addi­tion­al equip­ment.

How much does a wall-mount­ed gas boil­er cost:

  • Ger­man – from 40 000 r;
  • Ital­ian – from 32 000 r;
  • Kore­an – from 22 000 r;
  • domes­tic — from 14 000 rubles.

Internal arrangement of Viessmann wall-mounted boilers

Almost all devices are equipped with automa­tion that ensures their oper­a­tion with­out human inter­ven­tion. These include ther­mostats, dai­ly pro­gram­mers. With the help of the lat­ter, you can pro­gram the oper­a­tion of the boil­er for a day.

There is also a flame detec­tor that turns off the gas if the flame dis­ap­pears. The device will turn off if the pow­er sup­ply, gas sup­ply is inter­rupt­ed, the vol­ume of the coolant decreas­es or the draft is dis­turbed.

Installing a wall-mounted gas boiler, requirements

The most dif­fi­cult thing in the process of installing gas equip­ment is obtain­ing spe­cial per­mits and com­pli­ance with the nec­es­sary require­ments. The eas­i­est way to do this is by a com­pa­ny engaged in such work. Of course, you will have to pay for such ser­vices addi­tion­al­ly. The cost of installing a dou­ble-cir­cuit wall-mount­ed boil­er starts from 80 dol­lars.

It is for­bid­den to car­ry out work on the instal­la­tion of heat­ing equip­ment on your own. Yes, this is unsafe. You need to have not only per­mis­sion to per­form such work, but also expe­ri­ence. There­fore, we do not rec­om­mend installing a gas wall-mount­ed boil­er with your own hands.

If every­thing is done accord­ing to the rules, the wall-mount­ed appli­ance will not only become a source of heat, but will also please with its appear­ance. You should not save on high-qual­i­ty automa­tion — all its advan­tages will pay off.
