What should you pay attention to when choosing an electric boiler for a private house?

[ad_1]

Elec­tric boil­ers have recent­ly become very pop­u­lar. This is pri­mar­i­ly due to their per­for­mance. They are easy to use and install, safe, com­pact. There­fore, many peo­ple want to know how to choose a boil­er for heat­ing a pri­vate house. After all, in order for it to work, it needs elec­tric­i­ty. Anoth­er impor­tant fac­tor is the rel­a­tive­ly low cost, if we con­sid­er oth­er types of units.

basic information

Elec­tric heat­ing boil­ers are instal­la­tions that allow the use of an eco­log­i­cal source that does not pol­lute the envi­ron­ment and does not harm humans. Such units are often used in con­junc­tion with indi­rect heat­ing tanks. Some use them as an addi­tion­al source of heat.

The main com­po­nents that are need­ed to cre­ate a good sys­tem:

  • boil­er;
  • pump;
  • expan­sion tank;
  • safe­ty valve;
  • fil­ter;
  • Con­trol block.

What should you pay attention to?

Before choos­ing an elec­tric boil­er for heat­ing, you need to know some basic points.

Connection

It can be car­ried out through net­works of 220V or 380V. Units whose pow­er does not exceed 12 kW are con­nect­ed to any of the two types. But devices that con­sume more ener­gy need to be con­nect­ed only to the sec­ond option. There­fore, first of all, you need to con­sid­er the per­for­mance of the local net­work. Before buy­ing, be sure to con­sult with experts.

Heating method

There are heat­ing ele­ments, induc­tion and elec­trode devices. The lat­ter uses a spe­cial tech­nol­o­gy that has a num­ber of lim­i­ta­tions. Before buy­ing, you need to check every­thing with a con­sul­tant.

Power setting

Before choos­ing an elec­tric boil­er for heat­ing a pri­vate house, it is also impor­tant to know about pow­er adjust­ment. Depend­ing on the struc­ture of the unit itself, it can be smooth and stepped. Elec­tri­cal devices often have sep­a­rate heat­ing ele­ments. To set the desired tem­per­a­ture and the cor­re­spond­ing ener­gy con­sump­tion, you can sim­ply turn off some of them. Such an adjust­ment is just called step­wise. Most often, three ele­ments are installed inside. One heats up to half the max­i­mum pow­er, and the oth­er two only a quar­ter. There­fore, four options are pro­vid­ed — from 25 to 100%.

If pre­cise and smooth adjust­ment is need­ed, a rheo­stat must be installed in the design of the unit. Cheap low-pow­er boil­ers do not have such a detail.

Equipment

The elec­tric boil­er in the max­i­mum set, which it is sup­plied from the man­u­fac­tur­er, does not require addi­tion­al com­po­nents. There­fore, this option can be called the most prof­itable, although not always cheap. It is impor­tant to under­stand that if you buy an inex­pen­sive device, you will have to addi­tion­al­ly pur­chase sep­a­rate blocks. Togeth­er with the cost of instal­la­tion, this will def­i­nite­ly cost more.

Impor­tant! The sys­tem will work poor­ly with­out a pump, valve, fil­ter and expan­sion tank.

Installation options

Wall-mount­ed boil­ers are con­sid­ered the most pop­u­lar, as they save space. Floor-stand­ing options are usu­al­ly designed for large sys­tems that use a lot of coolant.

In addi­tion, before choos­ing an elec­tric boil­er for heat­ing, it is nec­es­sary to weigh all the pos­i­tive and neg­a­tive sides.

Advantages

This equip­ment has a lot of advan­tages:

  1. Appli­ca­tion. The devices are offered in a suf­fi­cient pow­er range — you can choose mod­els from 2 to 60 kW. Units up to 20 kW are used main­ly for the home. More pow­er­ful options are more suit­able for indus­tri­al premis­es. To ensure pro­duc­tiv­i­ty and reli­a­bil­i­ty, indi­vid­ual devices are often mount­ed in a cas­cade sys­tem.
  2. Ener­gy effi­cien­cy. The main advan­tage of mod­ern instal­la­tions is the stepped pow­er lev­el. This is what makes it pos­si­ble to save mon­ey while using it.
  3. Envi­ron­men­tal friend­li­ness. This effect is ensured due to the absence of the com­bus­tion process. There­fore, there is no need to cre­ate a sep­a­rate room. In addi­tion, there is no need to install a chim­ney. All this again makes it pos­si­ble to save space. Par­tic­u­lar­ly well suit­ed for com­mer­cial objects.
  4. Ease of man­age­ment. Due to the inde­pen­dent inter­ac­tion between the tem­per­a­ture con­trollers and the pro­gram­mer, auto­mat­ic oper­a­tion is ensured. This also allows elec­tron­ics to choose the best option in terms of the ener­gy expend­ed and the result obtained.
  5. Con­ve­nience. Qui­et oper­a­tion, sim­ple oper­a­tion, dura­bil­i­ty and rel­a­tive­ly low price.

Flaws

Before choos­ing an elec­tric boil­er for heat­ing a pri­vate house, it is also impor­tant to con­sid­er some of the dis­ad­van­tages of installing this equip­ment:

  1. The cost of elec­tric­i­ty. Despite all the pos­i­tive aspects in the use of elec­tri­cal equip­ment, they still can­not cov­er the over­all price tag for the ener­gy con­sumed. The use of such units in any case costs the own­ers more than gas or sol­id fuel instal­la­tions. In such cas­es, many have found a way out in con­nect­ing a tank to accu­mu­late excess heat. This allows you to sig­nif­i­cant­ly reduce your costs.
  2. Depen­dence on elec­tric­i­ty. Choos­ing this equip­ment, you need to imme­di­ate­ly under­stand that it is 100% tied to the cur­rent. In the event of a line break or any inter­rup­tions, the device turns off. And in no case should such a sit­u­a­tion be allowed dur­ing the heat­ing peri­od, oth­er­wise the entire sys­tem may fail. In the case of using an elec­tric boil­er as the main one, it is imper­a­tive to have an alter­na­tive with which it will be pos­si­ble to pre­vent the cool­ing of the room and the entire build­ing. For large hous­es, this can be a sol­id fuel boil­er. And in small ones — a fire­place.
  3. Suit­able wiring. If the build­ing is just being built, it is pos­si­ble to pro­vide wires in it that will be used by boil­ers of dif­fer­ent pow­er. And in the pres­ence of an exist­ing build­ing, some­times there may be prob­lems con­nect­ing the device due to the insuf­fi­cient capac­i­ty of the local elec­tri­cal net­work.

Which boiler is better to choose?

Units for space heat­ing are of for­eign and domes­tic pro­duc­tion. In the lat­ter, a sim­ple design is pro­vid­ed, and rel­a­tive­ly inex­pen­sive com­po­nents are installed inside. Most often they have a step adjust­ment. All this allows you to make the cost low­er than import­ed ones, as well as reduce the cost of pos­si­ble repairs.

For­eign devices have a more com­plex design and smooth adjust­ment. In addi­tion, some addi­tion­al fea­tures are often pro­vid­ed for con­ve­nient use. One of them can be called pro­gram­ming work for some time in advance. But they also have a cor­re­spond­ing cost.

An elec­tric boil­er is a good option that can eas­i­ly pro­vide heat­ing for a home. He has a lot of advan­tages. Although there are some dis­ad­van­tages. There are many fac­tors to keep in mind when choos­ing the right instal­la­tion. If all of them are tak­en into account, it will be a plea­sure to use this sys­tem.
