Today, heating equipment is a common means of heating rooms of various sizes. We are talking about both residential premises and industrial buildings.
Today, many different companies are engaged in the manufacture of electric boilers. Their products differ in many ways, from the quality of each part to the service life. Depending on the room for which the device is intended, it is also necessary to choose the manufacturer.
Zota electric boilers are manufactured for heating premises with a total area of 30 to 400 square meters. They are developed taking into account the wishes of each consumer and are oriented towards the Russian buyer.
The lineup
So, there are five models in the Zota model line of electric boilers:
Model Econom
This is the cheapest model, but in terms of operational and technical characteristics it is not inferior to any other model. This is a fully automated design with a remote control panel. The boilers can be installed in heating systems with natural and forced movement of the coolant.
A distinctive feature is that the boiler and the process control unit are located in different buildings. They are installed separately and connected by wires. It should be added that Zota boilers of economy class with a capacity of 3-15 kW can operate both from power relay installations and from standard magnetic starters.
The automatics of the heater makes it possible to regulate the temperature regime in the range from + 40C to + 90C. These are the optimal limits that allow you to adjust the mode to save fuel consumption. Note:
- Zota boilers of economy class with a capacity of 3-15 kW are adjusted manually.
- Units with a capacity of 18-45 kW are configured in automatic mode.
All boilers of this model are equipped with a self-diagnosis system. This allows you to identify in advance the flaws in heat engineering processes and breakdowns of units and parts.
Lux
The Lux model is considered the most demanded and popular. It is designed for heating houses with an area of 30-1000 m2. it is a fully automated electrical unit that is improved every year with new options and functions.
All boilers of this model are equipped with heating elements made of stainless steel tubes. The most advanced automatic equipment has been installed, which allows good savings on fuel consumption.
MK
These are mini boiler rooms, which include:
- An electric boiler with characteristics like the Zota Lux boiler.
- Power block.
- Control block.
- Expansion tank of membrane type.
- Circulation pump.
- Security block.
- Pipe junction with shut-off valves.
And all this in one building. What does this give in practice?
- Firstly, due to the compactness of the device for mini boiler rooms, a large installation space is not required.
- Secondly, this configuration allows you to save on additional materials.
- Third, it is easy to install. Here it is only necessary to connect to the power supply network and connect the pipes to the circuits of the heating system of the house.
Advice! For the convenience of monitoring and configuring the MC, we recommend installing a GSM module, which will allow you to control all heat engineering processes using a cell phone while far from home. This option is installed on demand only.
We add that MK Zota are produced with a capacity of 3 kW to 36 kW. For small country houses, this is the best option for heating.
Exploitation
Like most traditional heating boilers, the Zota Master 12 is very easy to operate and maintain. A large loading door and a large deep firebox allow storing a large amount of fuel, including large logs up to 480 mm long. It (door) is also used to clean the inner walls of the heat exchanger. The lower (ash) door serves for convenient access to the ash box, into which the ash formed during the combustion process is poured.
The air draft is regulated by the position of the air damper on the lower boiler door, which is either set manually or controlled by an additional mechanical thermostat (sold separately). The adjustment principle is very simple: the more the damper is slightly open, the stronger the thrust.
An important feature of the boiler, especially if it is installed in a country house, is the presence of a hob, on which, if necessary, you can easily cook a full meal or quickly boil water.
Installation rules
Like all types of electric boilers, the Zota brand is available in two variations: floor-standing and wall-mounted, single-phase and three-phase. The rules for installing single-phase models are simple:
- It is necessary to install the unit itself.
- Connect it to your home heating system.
- Plug it in.
The only thing that must be done is to run a separate power cable from the switchboard and install a separate machine. It is more difficult with three-phase analogs. If you are not an electrician, then the installation is best left to a professional. It is both reliable and safe.
The operation of the boiler is quite simple. There are provisions in the instructions with which you can easily adjust the device to the air temperature parameter you need. The device will do the rest by itself.
A fairly wide range of Zota electric boilers allows you to choose the required model exactly to the requirements of the consumer. Additional options will help to increase the usability. They, of course, increase the cost of the product, but the quality of work only improves from this. Therefore, it is worth paying attention to the options and choosing those suitable for the operating conditions.

Electric boilers are now installed quite often. But in most houses they serve only as a reserve. As a rule, the main ones are gas and solid fuel boilers, the operation of which is several times cheaper. But sometimes, with the appropriate equipment, an electric boiler is used as the main ...
How does the heat energy from an electric boiler become cheaper? How to connect correctly, which circuit to use?
One of the most important advantages of this heat generator is known - better comfort and trouble-free operation, and then ...
What power is required
How much power will you need to heat a house?
- It is known that for a well-insulated house you will need 10 kW per 100 square meters.
- For houses built using energy-saving technologies, this capacity will already be excessive.
- But if the box is characterized as "very cold", then 20 kW will not be enough ....
For an average house, the selection can be done just like this - 1 kW per 10 square meters. If in practice it turns out to be not enough, then it is economically expedient not to increase the capacity, but to insulate - first change the windows and doors, then increase the layer of insulation in the attic ....
