Logotherm®

Electronically controlled Heat Interface Units

Maximum efficiency and ease of operation

Highly efficient HIU’s ensures low primary operating temperatures
Fast reacting time of HIU providing instant DHW
Fully insulated units ensure minimal heat loss
Extensive range of DHW performances ranges

Logotherm® Heat Interface Units - Supply methods

Heating provided centrally through potentially multiple sources
Heating & DCW is distributed through risers to the apartments
There is a HIU unit in every apartment
The HIU provides heating as well as domestic hot water via a heat exchanger
