ELECTRIC BOILERS S+K TECHNIK

ESPRO series boiler

Power: from 6 kW to 18 kW

Voltage:  380 V

Max water temperature: 80 ° C

Boilers of the ESPRO series – have an integrated circulation pump with frequency regulation with energy-efficient characteristics, which reduces energy consumption. The ESPRO series are boilers designed as a universal heat source for heating residential and office premises. Electric boilers of the ESPRO series have an efficiency of 99%, due to this, high efficiency of using such equipment is achieved.

Stylish design solution, touchpad and WI-FI module for easy operation

On the front of the case is a touch screen for control. It has a high level of response and simplifies interaction with an electric boiler.

The screen displays the current temperature state of the selected heat sensor. The control plate is located in a separate compartment and is protected by an additional insulating layer.

App Regulation

ADVANTAGES OF S+K TECHNIK BOILERS

Distinctive characteristics of a series:

Regulation through the application

The ability to control the basic functions of the boiler through a mobile application

Compact boiler

compact dimensions due to the placement of the expansion tank on the rear surface of the boiler

Leakage protection

The design is protected against current leakage to the housing. Everyone who touches the boiler is safe.

Expansion tank

The boiler is already equipped with an expansion tank of the required volume for the boiler power

Full set

pump, flow sensor, safety valve, also included in the boiler kit

All the benefits of the ESBIG series

Preservation of installations, 2 types of temperature control, low noise power relay

Energy efficient pump with frequency control

Wilo para 15/6-43/sc

Heating elements and flask made of stainless steel

We use European quality AISI 304 steel. Stainless elements extend the life of the product
