Equipment Specification

Heat Interface Unit

The Heat Interface Unit shall provide the following capabilities:

Keep-warm functionionality is to be turned off.
When a tap is opened and primaries are cold, the HIU should draw a minimum primary flow rate of 20 litres/minute to accelerate delivery of heat.
Hot Water Priority is required.
Central heating temperature control to track available primary supply temperatures, reducing target temperature accordingly.
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 50C.
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.

We would like to be able to set independent inslation levels for risers, laterals and feeds. Is this possible?

Would be nice on the future is calculator could allow different pipe sizing on flow and return pipework.
