Electronically controlled heat interface unit.
For domestic applications.
Electronically controlled twin plate hydraulic heat interface unit (HIU), designed to provide instantaneous hot water and heating to the dwelling.
Features and benefits:
Some additional materials are used by component manufacturers such as valves and pumps. These are in small components within the assembly.
Expanded Polypropylene (EPP)
(l x h x d)
530 x 690 x 250 mm
One year from date of commissioning on replacement parts only.
Primary flow temperature
Primary return temperature
70°C Primary Flow = 27.9°C; 60°C Primary Flow = 29°C (Volume-Weighted Average Return Temperatures (VWART)).
<50 kPa (primary side), <10 kPa (heating).
Heating supply temperature
Hot water supply temperature
Fully insulated EPP casing.
Electronically controlled. The HIU controller shall utilize the secondary side DHW and heating temperatures to control Pressure Independent Control Valves (PICVs) located on the primary side of both plate heat exchangers to maintain the temperature. A keep warm function maintains a primary flow temperature at the unit.
