Electric boilers of the Standard Digital series are a high-tech and reliable solution for heating your home. This device is used for space heating from 30 to 150 sq.m or as an additional one in an existing heating system. Models of this series differ in high efficiency and reliability, produced with a 3 to 15 kW capacity, and may be connected to a 220V and 380V network (from 10,5 kW – only 380V). The Standard Digital electric boilers are designed as an alternative to the Standard boiler series, and unlike their predecessors, they have digital control, making it possible to adjust the work of the boiler more accurately. In addition, Standard Digital boilers are able to control the on/off time of the built-in Grundfos pump (UPSO 15/60-130) before and after turning on the heating elements, as well as two temperature sensors (coolant and air in the room). In this case, using the display, you can select the boiler operation mode - by the temperature of the coolant or by the air temperature, which is displayed using convenient light indicators. This series is equipped with a high-quality (made in Italy) hydrogroup of safety, i.e. an automatic air vent, a digital pressure sensor, a safety valve. Standard Digital boilers have additional electrical protection – a redundant modular contactor, while the main switching devices are highly reliable low-noise mechanical relays (boilers up to 6 kW at 220V) or modular contactors. Boilers of this series can only be operated in a closed heating system with a pressure of at least 1 bar. The presented series is characterized by wide functionality and easy use. The boiler body is made of high quality steel and has anti-corrosion treatment. To give it additional protective properties and an elegant appearance, powder painting technology is used.
