Description of each solution

MEMBER A1 “ONE HEAT PUMP FOR ALL” (1.1)

One central heat pump system for the whole building, both for space heating and DHW.

MEMBER A2 “ONE FOR HEATING, ONE FOR DHW” (1.2)

One heat pump system for each mode. One for space heating, separate one for DHW.

MEMBER A3 “HP FOR HEATING, ANOTHER DEVICE FOR DHW“ (1.3)

One heat pump system for the space heating, separate heat generator (fossil, biomass, electric, …) for DHW.

MEMBER A4 “ HP FOR DHW, ANOTHER DEVICE FOR HEATING” (1.4)

One HP system for DHW, separate heat generator (fossil, biomass, electric, …) for space heating.

MEMBER A5 “ONE HYBRID HEAT PUMP FOR ALL” (1.5)

One hybrid heat pump system for space heating and DHW for the whole building.

MEMBER B1 “ONE MODE – CENTRAL, SECOND – DECENTRAL“ (2.1)

One central heat pump system for one mode (for example space heating) and decentral heat pumps for the second mode (for example DHW). Also possible with a central heat pump if lower temperature level available or decentral heat pumps for a higher temperature level.

MEMBER C1 “ONE HEAT PUMP FOR A NUMBER OF APARTMENTS” (3.1)

One heat pump system for space heating and DHW for several apartments (usually grouped by levels or staircases).

MEMBER C2 “APARTMENTS GROUPED BY HEAT GENERATOR” (3.2)

The apartments are grouped by heat generators (usually grouped by levels or staircases)

MEMBER D1 “INDIVIDUAL SOLUTION FOR EACH APARTMENT“ (4.1)

Each apartment has individual concept of space heating and DHW.

MEMBER D2 “ONE APARTMENT – ONE MODE“ (4.2)

Decentral heat pump for one mode for one apartment.

MEMBER E1 “HEAT PUMP FOR AN INDIVIDUAL ROOM” (5.1)

One heat pump for space heating (or cooling) for one room of the apartment.
