 How can you save energy and money on your district heating system installation?

Simple - use the COMBIPUMP™ and COMBIPACK™ systems as manufactured and supplied by GRE Ltd.

Many district heating systems waste energy in the form of:

  • Pump power – by running the pump to circulating the primary flow when there is no demand

  • Heat loss to the ground – too high flow and running too often causes much heat loss to the ground

 

The GRE Ltd COMBIPUMP™ and COMBIPACK™ systems provide, out of the box, the following benefits:

 

  • Only runs the pump when needed, at the speed necessary to maintain the required pumping capacity
  • Detects demand from COMBIPACK™ interface units without interconnecting wiring
  • System designed to run at lower flow rates, yet still deliver heat effectively
  • Simple, reliable way to distribute heat on a district heating network

 

 

 

 

 

 

Key Features of the GRE Ltd COMBIPUMP™ and COMBIPACK™ are:

  • Single or twin head pump set, mounted on skid with all required controls, isolation valves

  • Variable speed pump control providing the exact flow required to suit system demand

  • Matched heat interface units automatically modulate flow on the primary circuit in response to system demand
