Direct heating and instantaneous DHW

Direct heating stations with instantaneous domestic hot water preparation are used in single-family houses, where pressure and temperature conditions allow direct connections, but the most common use is in the multi-family buildings with decentralized heating and DHW installations. Each building and apartment has a directly connected substation or flat station with integrated production of domestic hot water. Single or multiple heating circuits (e.g. radiator, floor heating system) are supplied with heated water from the central heat source.

Today, renovated or new buildings are obliged to make at least partial use of renewable energy sources. Modern central heating systems can use buffer tanks to combine different energy sources.

All buildings must comply with strict DHW hygiene regulations.

Features and benefits

• Integrated components ensure safe operation, increases durability and minimize whole life costs

• Compact design - Minimum space required for installation

• Electronic or flow/thermostatic control of heating and domestic hot water

• Operates independently of differential pressure and flow temperature

• Low energy loss

• Domestic hot water is produced on demand, without storing and with Min. risk of lime scale and bacteria formation

• Heating systems can combine different energy sources

• If the volume of water held between the water heater and the taps is less than 3 liters, no regular hygienic testing is required
