Direct Underfloor Heating Solutions

General Specifications


Definition
Heat interface units , is complete solution for apartments for underfloor systems
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.
Thermostatic controlled three way valve controls the underfloor heating temperature.
Energy efficient electronically controlled pump controls the flow of underfloor 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.
