Air-to-Water Heat Pumps

Altherma 4

Available HeatAdapt control options:

1. Peak price control by suspending heating and domestic hot water production during highest electricity prices. The number of peak hours during which heating is reduced depends on the weather forecast. In extremely cold weather, the heat pump cannot be turned off for extended periods due to the building's heating requirements.
2. Preheating of domestic hot water during the lowest price hours when the heat pump is connected to the boiler

Note: R290 refrigerant. E.g. EPSKS-AV3 (4/6/7 kW), EPSK08AW1 (8–14 kW)

Altherma 3 E-generation (all models, with smart grid)

Available HeatAdapt control options:

1. Peak price control by suspending heating and domestic hot water production during highest electricity prices. The number of peak hours during which heating is reduced depends on the weather forecast. In extremely cold weather, the heat pump cannot be turned off for extended periods due to the building's heating requirements.
2. Preheating of domestic hot water during the lowest price hours when the heat pump is connected to the boiler

Note: E.g. indoor EHBX08E9W, EHBX08E6V; outdoor ERGA08EVH

Altherma 3 D-generation EGSAX/ERLA (with smart grid)

Available HeatAdapt control options:

1. Peak price control by suspending heating and domestic hot water production during highest electricity prices. The number of peak hours during which heating is reduced depends on the weather forecast. In extremely cold weather, the heat pump cannot be turned off for extended periods due to the building's heating requirements.
2. Preheating of domestic hot water during the lowest price hours when the heat pump is connected to the boiler

Note: E.g. EGSAX-D9W (ground-source hybrid), ERLA11-16DV3 (high-capacity outdoor)

Altherma 3 C- and D-generation + LAN adapter BRP069A61 (smart grid enabled)

Available HeatAdapt control options:

1. Peak price control by suspending heating and domestic hot water production during highest electricity prices. The number of peak hours during which heating is reduced depends on the weather forecast. In extremely cold weather, the heat pump cannot be turned off for extended periods due to the building's heating requirements.
2. Preheating of domestic hot water during the lowest price hours when the heat pump is connected to the boiler

Note: E.g. indoor EHBX08DA9W, EHBX08DA6V; outdoor ERGA-DV3

Altherma 3 C- and D-generation (excl. EGSAX/ERLA models)

Available HeatAdapt control options:

1. Peak price control by suspending heating and domestic hot water production during highest electricity prices. The number of peak hours during which heating is reduced depends on the weather forecast. In extremely cold weather, the heat pump cannot be turned off for extended periods due to the building's heating requirements.

Note: E.g. indoor EHBX08CB3V (C-gen), EHBX08DA9W (D-gen); outdoor ERLQ-CV3 (C-gen), ERGA-DV3 (D-gen)
