Home stations

Home stations are the proven solution for decentralized domestic hot water heating in residential buildings. Due to different circumstances, there is a wide range of functional and hydraulic requirements that we can cover with our portfolio of electronically controlled station types.

Frequently asked questions about home stations, simply explained.

Home stations are decentralized systems for DHW heating and - depending on the design - for supplying heating to individual apartments.
Our home stations (e.g. VARIO fresh-flat) work with fresh water heater technology: fresh water is heated on demand via a plate heat exchanger. An electronically controlled valve (OptiStep) ensures stable hot water temperatures - even with low water withdrawal.

Short pipe runs → fast heat and low heat loss

  • Hygienic hot water preparation on demand - without hot water storage tank and with low legionella risk
  • Flexible modular construction: Apartment can be individually equipped or extended later (e.g. drinking water + heating circuit).

Ideal for apartment buildings, new builds and renovations - wherever residential units need to be supplied separately and work hygienically and efficiently.

Depending on the type and equipment, the stations take over:
  • DHW heating using the flow-through principle
  • Optional circulation pump control for hot water circulation
  • Heating circuit control for room heating (e.g. controlled underfloor heating or radiators)

Very hygienic. The drinking water is heated using the flow-through principle and is not stored. This means there is no stagnant hot water - a decisive advantage in terms of legionella and general drinking water quality.

Yes, but the cost is low. An annual visual and functional inspection by qualified personnel is recommended. This involves checking the heat exchanger, valves and control system for proper operation to ensure long-term efficiency and safety.

Home stations are energy-efficient as they prepare hot water using the instantaneous principle. In accordance with DVGW W 551 and DIN 1988-200, the obligation for legionella protection temperatures (60 °C/55 °C) does not apply if the 3-liter rule is observed. This means that the hot water temperature and subsequently the supply temperatures can be lowered. In terms of performance, our home stations are designed for a slight increase (+5 K)t.

Yes, the modular design makes it possible to combine functions such as DHW, heating circuit control or circulation individually or to add them later. This means the system remains flexible for different living situations and future requirements.

The option of lowering the hot water temperature in accordance with DVGW W 551 and DIN 1988-200 reduces energy consumption. This increases the efficiency of the overall system and enables the optimum use of low-temperature heat generators such as heat pumps.
