Heat Metering


AET Energy offers a range of heat metering solutions for district heating and residential applications


Combined HIU



3PHC is a terminal for district heating plants for heating, cooling and domestic hot water production by means of plate heat exchangers. The primary hot and chilled fluids are provided by a central boiler/chiller that supply all units through main pumps. Plate heat exchangers are placed between the primary and secondary apartment circuit (heating and cooling) in order to separate them and allow an independent regulation in each apartment; simplifying the design and installation


SND Ultrasonic Heat Meter

The SND ultrasonic heat meter for heating and cooling is designed for residential metering applications and uses the latest technology for high quality measurement and long term stability.  With no moving parts it is virtually maintenance free


ESC Satellite Heating Unit

The ESC satellite heating unit provides indirect heating or cooling, designed for wall-mounting or built-in installation.  Two models are available, with and without circulation pump


Twin and Single Plate HIU

Single Plate HIU_MSPDC

The MTP and MSP heating units provide indirect heating and instantaneous hot water with thermostatic control.  It has been designed for wall mounting or built-in installation.  An ultrasonic heat meter guarantees accurate consumption metering
