Model LTV + double heat exchanger package

Categories: ,

Description
The hydraulically separated system 4-pipes fitted with 2 heat exchangers is a perfect solution for installations where heating and cooling is done by two separate sources. (hot and cold). Both sources are connected to the underfloor heating circuit through a heat exchanger.

This manifold is also a suitable option when the system pressure of the primary side is above the maximum pressure of the underfloor heating side. By adding the right zone control system the primary actuators are powered when needed which ensures only hot or only cold supply water.
