Having the correct heating system is crucial for maintaining a warm and comfortable home. An option that has become more and more popular recently is the electric boiler. Electric boilers heat water using electricity rather than fossil fuels like gas or oil, making them an economical and ecologically friendly method of heating your home.
So what’s the operation of an electric boiler? The basic idea behind how an electric boiler works is that it heats water by using electricity. There are heating elements inside the boiler that resemble those in an electric kettle. These components heat up when the boiler is turned on, and the water that passes through them absorbs this heat.
Warmth is distributed throughout each room of your house via the pipes that house the heating system once the water has been heated. Additionally, some electric boilers come equipped with integrated pumps to aid in circulation, guaranteeing that the heated water effectively reaches every area of your home.
The adaptability of electric boilers is one of their benefits. Electric boilers do not release any hazardous emissions when they are in use, in contrast to gas or oil boilers, which need a flue for venting. This means that you don’t need a chimney or other specialized ventilation system to install them almost anywhere in your house.
Furthermore, almost all of the electricity used by electric boilers is converted into heat, making them extremely efficient. They are therefore an affordable choice for heating your house, particularly if you reside in a place where electricity is reasonably priced.
Device | An electric boiler is a heating appliance that uses electricity to generate heat for heating water, which is then circulated through the house"s heating system. |
Principle of operation | The electric boiler works by using electrical resistance to heat the water. When electricity flows through the heating elements inside the boiler, it creates heat, warming up the water. This hot water is then pumped through pipes to radiators or underfloor heating systems, providing warmth to the rooms. |
Advantages and disadvantages of electric boilers
Depending on the kind of heating element, the positive and negative aspects of the electric heating boiler must be analyzed.
Among the benefits of induction heating are:
- The largest efficiency in heating (up to 99.5 %) with small unit size.
- A long service life (up to 30 years) and the reliability of devices, the unit power of which is up to 60 kW.
- The coolant can be not only water, but also non -freezing liquids or oil.
- Safe operation and small service costs.
The high price, challenging pipe strapping and power supply connection are the only drawbacks. An electric boiler with tubular electric heaters has the following benefits: it heats water fast, is comparatively inexpensive, and requires minimal maintenance and connection to the heating system.
Several more drawbacks exist:
- The indirect method of raising fluid temperature reduces the efficiency to 97 … 98 %.
- We need water treatment, t.To. Otherwise, during heating on the body of the heating element, a scale appears, worsening heat transfer and spreading by wiring and radiators.
- Not a compact design.
- Large load on the mains during operation and current throws when turning on.
- When the heater works, the tungsten wire inside it evaporates and burns out, demanding the replacement of the entire part.
- The destruction of the heater housing and the appearance of the danger of an electricity strike is possible.
- Units have simplified automation, requiring additional investments.
An electrode boiler’s advantages include being more compact than all of the aforementioned units and having a higher specific power. It also differs in that it uses less energy and has a more dependable and straightforward constructive scheme. However, connecting and installing it are not easy tasks.
It is operated in "Start – Stop" mode and only uses its maximum power. Because electrodes are prone to erosion and becoming covered in bits, they need to be changed on a regular basis. A particular kind of water is used as a coolant. Moreover, variations in the salt content have an impact on heat transfer.

The electric boiler device looks like this in the majority of cases. The heating system’s feed and reverse pipelines are connected by a steel container equipped with nozzles. The boiler water heating device is designed differently; it has built-in induction coils, electrodes, or heating elements.
They calculate the unit’s boiler room cost (in decreasing order). There are instances where equipment components that come into contact with heated water have built-in circulating pumps and thermal insulation. Automation (air discharge, termistors, pressure gauges, etc.), protection (from overheating, current leakage, etc.), and heat power control are undoubtedly present.
Operating principle
The primary similarity among the various types of electric boilers is their ability to raise the temperature of liquids, such as water. The way that the various types of equipment convert electricity into heat is the only difference between them.
Boiler with Ten
For boiler apparatus that has Tenas The high-resistance (tungsten) wire is subjected to electric current, which causes it to heat up.
Heat is transferred from the backfill of quartz sand and the heater body to the water circulating within the boiler tank, where it is subsequently transferred to the heating systems’ radiators or the "warm" floor’s serpentine.
Electric boiler
Boilers with U electrodes Everything occurs in a slightly different way. A metal electrode with the attached "phase" is positioned along the axis, and a "zero" wire is connected to the steel cylindrical housing.
Unedistilized heating water, a conductor with some electrical resistance, is forced to move inside with the help of the pump. T.O. will heat up as it moves through this electrical liquid. Only the strength and duration of the electric current’s exposure determine how much the temperature rises.
Induction
Within an induction boiler The electromagnetic induction phenomenon is the cause of water heating. Power is transferred by the wire-wrapped coil. It has a metal core inserted into it at the same time. Vortex currents form around the coil, warming a variety of cores and washing water with them. The heat carrier senses heat as a result.
In understanding the device and operation of an electric boiler for heating a house, it"s crucial to grasp its simplicity and efficiency. Unlike traditional boilers fueled by gas or oil, electric boilers use electricity to heat water, which then circulates through radiators or underfloor heating systems. The principle is straightforward: the electric boiler contains heating elements that warm the water as it passes through. This hot water is then pumped to where it"s needed in the house. Electric boilers are often favored for their ease of installation, lack of emissions, and precise temperature control. They"re also quieter and typically require less maintenance compared to their fossil fuel counterparts. Overall, electric boilers offer a clean, reliable, and environmentally friendly solution for keeping homes warm and comfortable.
Types of electric boats
The following conditional classifications apply to electric boilers:
- installation – wall or floor;
- purpose – only for heating (single -circuit) or for heating together with hot water supply (double -circuit);
- in power voltage and thermal power, respectively- one- (up to 6 kW) and three-phase (more than 6 kW).
Electric boles are classified as either domestic or industrial depending on their use.
A contemporary and effective way to maintain a warm and cozy home is with an electric boiler for heating. Since electric boilers don’t need a flue or chimney, they’re simpler to install and maintain than conventional gas boilers. To heat your house, they use electricity to heat water, which is then pumped through radiators or underfloor heating systems.
