Equipment Specification

Heat Interface Unit

The Heat Interface Unit shall provide the following capabilities:

Hot Water Priority is not required.
Central heating temperature control to be based on fixed temperatures.
Peak DHW load of 35.7 kW.
Primary return temperatures at peak DHW load should not exceed 25C.
Peak central heating load of 4 kW.
Primary return temperatures at peak central heating load should not exceed 60C.
Maximum Differential Pressure of 100 kPa.
Minimum Differential Pressure of 50 kPa.
To ensure compliance with the above, the HIU should be tested independently to Fairheat HIU Regime, or equivalent.
