Your choice of Heat interface Unit (HIU), for dwellings connected to a communal or District heating network, is a crucial element of the system design.
Installing the best solution from the outset can provide a more efficient and easy to manage scheme. With advances in technology and growing experience in system design, improved methods of controlling HIU’s and the primary network are available.
Evinox Energy's ModuSat units use an advanced Proportional Integral Derivative (PID) control logic, in combination with PICV’s and a fast acting actuator, which modulate the primary flow rate to match the DHW or HTG demand, and respond instantly to the changing loads. This ensures that end user comfort is achieved by providing consistent, safe hot water at the tap, as well as guaranteeing the low return temperature to the primary network at all times.
The use of PID controlled PICV’s in HIU’s means that only one valve is required for differential pressure control, flow modulation and full energy shut off. This reduces the size and weight of the unit, keeps maintenance costs to a minimum and increases functionality.
In addition, Evinox Energy HIU’s are supplied prepayment ready as standard, with a room controller for the end user, meaning there is no requirement for additional controls, sensors or equipment to switch the end user to a debt free Pre-Payment system. The integrated technology also enables remote monitoring for diagnostics and improving the efficiency of the system.
Evinox Energy is confident that the future of HIU’s lies in electronically controlled units that provide full comfort to the end user, whilst also delivering important information regarding the operation of the system, which can be monitored, adjusted or regulated remotely over the internet.
