The boiler TK-eLG is intended to support the heat pump. This device does not have a working thermostat (it has a protective thermostat), but it forwards the information from the temperature sensor to the thermoregulator of the heat pump. The thermoregulator of the heat pump decides whether and when the electric heater will be switched on. The electric boiler TK-eLG plays an important role for the proper operation of the heat pump that uses ecological gas R32 for which the standard does not allow the installation of electric heaters in the heat pump housing.The control unit of the heat pump will activate the boiler TK-eLG in the following situations: 1. If the water temperature is less than ≈20 °C, the heat pump will not be able to start without preparation (heating) using an electric heater. 2. Defrosting when the air temperature is low can be time-consuming or impossible without the help of an electric heater. 3. On extremely cold days when the COP of the heat pump has the lowest value, el. the boiler is switched on as backup to keep the heating of the building at a comfortable level. 4. In case of failure (servicing) of the heat pump, the electric boiler takes over the heating of the building - until the pump is not in operation.The TK-eLG boiler is intended for wall mounting. The IP20 model is intended for indoor mounting and is fixed to the wall using the supplied mounting set. The IP54 model is intended for outdoor mounting. Thanks to the high degree of protection (IP54), it can be installed in the immediate vicinity of the heat pump, which simplifies the execution of the hydraulic installation and does not damage the interior of the residential building. It is produced in two variants with hydraulic connections on the left or right side of the boiler. When designing and installing, be especially careful when choosing the IP54 model, whether the hydraulic connections are on the left or right side of the boiler.

The eTK model is intended for wall mounting. Small dimensions make this model suitable for installation in any part of the building. They have found application as a basic source of energy, but very often also as a backup solution with pellet, gas, wood boilers... The boiler can control the operation of an external pump. The boiler is controlled by a microprocessor thermoregulator that optimally uses each heater. The user can see the current temperature on the display at any time, or by moving through the menu, he can quickly and easily view all system parameters. This model, like the others, has the possibility of being controlled via a room thermostat. Unlike the previous model, in addition to the added microprocessor unit, maximum safety is ensured by adding a safety circuit consisting of a 3P automatic fuse with a voltage release, which cuts off the main power supply in case of overheating. Advanced software, based on dynamic temperature changes, modulates the engaged power of the heater, so that the set temperature of the boiler is precisely maintained with the lowest energy consumption.

The eCompact Plus series are block boilers that have the same dimensions as the mTronic, with identical hydraulic parts of the boiler, but for less demanding users. It is intended exclusively for heating, it is not intended for the preparation of domestic hot water. The user module consists of two seven-segment displays and LEDs that signal which parameter is displayed on the display. Also, the setting is maximally simplified with three soft touch buttons below the display. Work is controlled by a microprocessor unit. With its functionality and quality, this boiler has positioned itself in the category of premium boilers. Reliability in operation and service characteristics are, as with all Mikoterm models, at the top level.

Electric boilers TK-Professional 40÷240kW are compact devices intended for heating larger residential or commercial buildings. The boiler body is made of sheet steel, tested at a pressure of 6 bar, while the maximum working pressure is 4 bar. The flanges with which the boiler is connected to the heating installation are located on the back side of the boiler. There is a filling and emptying tap on the return pipe of the boiler (lower), and a safety valve and an automatic venting pot on the pressure pipe (upper). The lower door covers the switchboard with complete boiler automation and regular clamps for connecting the power cable, as well as auxiliary terminals for connecting the control for the circulation pump and the room thermostat. The boilers are equipped with the "Multistage protection" protection system, which permanently monitors the temperature and pressure in the system. If the pressure or temperature approaches illegal values, it displays appropriate warnings on the display, and if the limit values ​​of pressure or temperature are exceeded, it turns off all heaters, that is, in the third level of protection, it turns off the complete power supply of the device using voltage triggers, which guarantees safety. Boilers TK-Professional 40÷240kW can optionally be connected to a centralized monitoring and control system (BMS, SCADA,...), via the RS485 RTU module, using the ModBus protocol. The possibility of connecting up to 10 boilers (of the same power) in cascade mode with an additional Cascade regulator .
