About the client
GreenHub received a request from a client to solve the issue of electric heating automation. There was a multifunctional 15-story residential complex with 300 apartments in progress. The client chose electric heating for it since the urban heating network and the main gas pipeline were unavailable.
Problem
The client was looking for the best cost-effective option for electric heating of a residential complex, choosing among the following options:
-
Central electric boiler heating
-
In-apartment double-circuit electric boilers heating
Goal
The following goals were determined to solve the problem:
-
To save on the heating system and don`t lose the quality of services for residents.
-
Comply with the building code, which is mandatory for all buildings with electric heating.

Consulting
Project development
Equipment installation
Starting-up and adjustment works
Consulting
Research results allowed the customer to choose the option of in-apartment electric heating boilers to save on the following aspects
On technical premises
Saving about 100-200 m2 of technical/engineering space with the opportunity of using it as a commercial property.
On networks
No need to construct heating and hot water networks
On meters
No need to install hot water and heating meters and organize readings accounting.
On boiler room
No need to build a boiler room or individual heating point
Solution
Electric heating automation system was mandatory according to the building code and provided the customer with the following opportunities
Reducing the required power in the technical specifications for connection to external power networks
Keeping the load of the object within the permitted power limits
Prevention of peak overloads during blackouts
Results
Estimated power
As a result, we could include the electric power of boilers, covering the heat losses of the walling of each premise on the calculations instead of the rated wattage. It reduced the final estimated wattage of the heating system by 38%.
Final power
The simultaneity factor was applied in calculations thanks to the electrical load balancing system. It reduced the final power of the heating system by 68%.
