2. Size: En 20kW, 91% efficiency, remote control, 5-year warranty.

Design and device

The design and operation principle of all gas heating boilers are the same. Boilers differ in terms of control and heating type, but they share several complementary qualities.

Principal components of design:

• heat carrier with built-in heating elements;
• Remote Control;
• temperature limiter.

A circulation pump with a tank, filters, and a safety valve are occasionally included in models.

Characteristics of electric boilers:

• a regular outlet can only withstand heaters that have a power of no more than 3.5 kW;
• single-phase connection is built into boilers with a power of up to 12 kW. But it is recommended to connect devices with a power of up to 7 kW to 380 volts;
• The efficiency of the boilers is approximately the same, equal to 100 percent. The energy spent turns into heat;
• electric boilers require a lot of energy, customers need to be prepared for high costs.

To make sure your electric boiler effectively meets your heating needs, it’s important to take into account both the device’s design and technical specifications. In order to help you make an informed choice, this article will walk you through the important features to consider, such as capacity, energy efficiency, and safety features. It will also list the top five models available and provide comprehensive technical descriptions of each one.

How to choose the right one?

The customer should consider the features of the appliances when selecting an electric boiler; these should be considered prior to making a purchase.

Number of circuits

Boilers with a single circuit heat the coolant in the heating system. You should select a double-circuit boiler or an additional water heater to supply hot water.

Two working circuits—one for heating and the other for producing hot water—are included in their design. However, the high electricity consumption of these boilers raises the price of heating and water.

Power

The power of the electric boiler is the primary parameter you should consider. It is important to take into account the building’s heat loss area and intensity. The power also decreases as the supply voltage drops.

For hot water supply, a double-circuit electric boiler offers a maximum 25% power reserve.

Supply voltage

The kind of supply voltage is the next consideration. Boilers typically run on low power and are powered by a single-phase 220V network.

Lay a separate connection line if you need to connect equipment with greater power than 10 kW.

Equipment

The circulation pump, expansion tank, safety group, temperature sensors, and programmer make up the unit’s basic equipment.

Safety

The device’s added safety features will help save electricity and shield the owner from malfunctions. The device’s fuse is external to it.

It is best if the fuses are oriented in different directions. They can be set off by critical measurements of electricity, coolant freezing, or overheating.

Installation

It is important to take the unit’s installation site into account. It has two mounting options: floor or wall.

Wall installation is a better option for heating a private residence. However, the client might only have the full version if the device is big. In this instance, it makes sense to store the unit in a designated boiler room or storage area within the home.

It is better to choose a wall design of devices for an average apartment.

Heated area (calculation)

It is useful to use the calculation for a room that is 18 square meters as an example. The formula is as follows:

1800 Wx 18 sq. m x 100 W

It turns out that 1.8 kW of power is needed to heat eighteen square meters for an hour. The heat released into a specific area of the heating radiator is divided by the result.

Considering the information from the 170 W passport, we ought to:

10.59 is 1800 W/170 W.

After that, the result is rounded to the nearest whole number, or 11. This indicates that buying a unit with 11 sections is advised for a space of 18 square meters.

16 kW of boiler power is required to heat 160 m^2.

It is worthwhile to perform the following calculation for a 65 m2 apartment with three meter ceilings:

• Determine the power by area – 65m2/10m2 = 6.5 kW;
• Amendment is made to the region – 6.5 kW*1.2 = 7.8 kW;
• It should be added 25%, given the heating of water 7.8 kW*1.25 = 9.75 kW;
• 10% is added to account for cold temperature: 7.95kW*1.1 = 10, 725kW.

The outcome is rounded to eleven kW of power.

Control

You should think about the design and usability of a control when selecting one. Boilers essentially consist of electronic panels with a rotary switch and multiple keys. However, there’s also a fully automated one.

Everything is dependent on the individual preferences of the buyer, which you should discuss before making a purchase.

Additional functions

When observing supplementary features, consider integrated controls that enhance the feature set.

In a specialty store, all other options should also be discussed with the manager.

• Protection from cold temperatures;
• Fuses are installed to prevent excessive temperatures;
• Thermometer for determining temperature;
• Indication when the device is activated;
• Blocking nas also has protection;

Types by heating type

Heating elements new boilers

These devices contain multiple heaters in the shape of pipes and plates that are submerged in a water tank. intended to heat water. They occupy half of the bathroom and have a rather hefty design. The control panel is used to control boiler power. The dimensions that can be installed should be taken into consideration when selecting a device with care.

Benefits

• Suitable for private homes;
• They have a simple design and control;
• Nice price for devices;
• Operation using various coolants is allowed.

Drawbacks:

• Impressive size of the unit;
• When using water, scale may form;

Electrode boilers

With built-in electrodes that produce a potential difference, these boilers heat differently. Because of the dissolved salts in the water, the kind of carrier is an electrolyte. Heating is provided by conductor and water resistance.

Benefits

• Compactness;
• Simplicity of design ensures low price.

Drawbacks:

• Only water with a certain resistance can be used as a coolant;
• Long-term use requires replacement of electrodes.

Induction boilers

For private homes, their design is more intricate. The coil is wound around a core located inside the pipe. The coil generates a current when it is connected to the network, and electromagnetic induction causes heating.

The core temperature rises as a result.

Benefits

• The unit is not afraid of wear and serves for quite a long time;
• Scale or overheating is not dangerous;
• The type of coolant does not matter, the main thing is that it is liquid.

Drawbacks:

• Complex design;
• Very high cost.

What parameters to pay attention to?

It is important to be aware of the size of the room in which the electric boiler will be placed before making a purchase. The client will then know exactly what size unit he needs.

The smallest electrode models are the most compact, but there are also tiny versions with heating components.

Given the high cost of electricity, using a boiler as the primary source of heating is an unaffordable luxury. It is preferable to have a backup boiler or storage water heater to heat water. It is advisable to speak with an expert and let him know which room the heater will be placed in after considering all of the features of the equipment.

After then, there’s a greater chance of getting the needed unit. A range of options are available for models, which impact the devices’ price.

You should only consider features that will undoubtedly be helpful when using the boiler when making your selections.

When considering all of the features and options available in each model, electric boilers become a must-have investment for homeowners.

In general, people buy devices with heating elements because it is the simplest to locate a model that fits their needs in this category. However, other choices might be better suited for a business, factory, or other establishment.
