General Specifications
Definition
Heat interface units , is complete solution for apartments for hydraulicly separated systems.Secondary system can be radiator or underfloor heating.
Balancing valves for complete unit is used to control the pressure difference across and in the system.
Stainless steel heat exchanger and thermostatic controlling valve to have a stable temperature domestic hot water. Up to 23 lt/min.
Stainless steel heat exchanger is used to hydraulicly separate the apartment from the main system.
Thermostatic controlled valve is used to control the secondary side supply temperature.
Energy efficient electronically controlled pump controls the flow of secondary side heating.
All the consumption of heating and domestic hot water preparation can be measured by one heat meter and cold water meter.
All the piping is stainless steel.
