3 Combi Port E system description
Combi Port E is a prefabricated heat interface unit suited for use in
multifamily houses or large residential buildings. The ready-to-install
unit supplies domestic hot water and control of the domestic heating
system, measurement of heating energy and water consumption.
3.1 Operating principle
SD0000060
3.2 Functional description
In Combi Port E, the cold water is heated only when required in the
flow-through principle via a stainless steel high-performance plate
heat exchanger. This always ensures low heating water return
temperatures. The energy is supplied by heating water with a flow
temperature of at least 55 °C via the heating water flow.
The heat interface unit has an insulation cover with a combined
function. A thermal separation between heating and tap water side
secures that no heating of the cold water pipes takes place.
Domestic hot water:
The domestic hot water is generated only on
demand with an integrated controller ensuring the process flow. The
heating water flow is controlled by the valves depending on the hot
water requirement. This ensures a constant hot water temperature. If
no hot water is needed, the valve stops the supply of heating water
through the heat exchanger. It can cool down which is beneficial for
the hygiene.
Domestic heating:
Combi Port E manages independently the
hydraulic balancing between hot water and heating. This is achieved
through the integrated regulating valves.
The heat interface unit is kept at temperature during normal
operation. If no heat is required, the ECO mode becomes active and
energy is saved.
The room temperature control is carried out with either Uponor
Smatrix or Uponor Base flexiboard.
