Loading…Indirect Boilers
Indirekt beheizte Boiler werden zur Warmwasserbereitung über eine externe Wärmequelle eingesetzt, zum Beispiel über eine Wärmepumpe, einen Heizkessel, eine Solarthermieanlage oder ein anderes Heizsystem. Die Wärme wird über einen oder mehrere Wärmetauscher auf das Trinkwasser im Boiler übertragen.
Bei Hewa finden Sie indirekt beheizte Boiler in verschiedenen Ausführungen, darunter Stahlboiler, Edelstahlboiler und passendes Zubehör. Achten Sie bei der Auswahl auf Inhalt, Material, Anzahl der Wärmetauscher, Anschlüsse, Aufheizleistung, Isolierung und Eignung für die Wärmequelle.

Indirect boilers for efficient domestic hot water
Indirect boilers prepare domestic hot water using an external heat source. Heat is transferred to the water inside the boiler through a heat exchanger. This makes these boilers suitable for heat pumps, boilers, solar thermal systems and combined installations where hot water comfort and system efficiency must be well coordinated.
Selecting an indirect boiler
The right indirect boiler depends on domestic hot water demand, heat source capacity, available space and the required number of heat exchangers. A boiler with one heat exchanger may be suitable for a standard heat source, while a version with two heat exchangers is useful for combinations with solar and boiler or heat pump systems.
Within this category, also review steel indirect boilers, stainless steel indirect boilers and indirect boiler accessories.
Important when choosing indirect boilers
- Match the volume to hot water demand, draw-off points and usage profile
- Check whether the heat exchanger matches the heat pump, boiler or solar thermal system
- Check material selection, such as steel or stainless steel, depending on the application
- Check connections, sensor positions, anode provision and installation height
- Check insulation value, standing loss and available installation space
- Check maximum operating pressure, temperature class and safety components
- Have sizing and connection assessed by a qualified installer
Applications within indirect boilers
Heat pump systems
For domestic hot water preparation via a heat pump, where a suitable heat exchanger and sufficient boiler volume are important for efficiency and comfort.
Heating installations
For hot water preparation via a boiler or another heating system. Suitable when domestic hot water is generated externally and stored.
Solar thermal systems
For installations where solar collectors are combined with backup heating via a boiler, heat pump or electric support.
Hot water comfort, heat exchanger and efficiency
A correctly selected indirect boiler provides reliable domestic hot water availability and efficient heat transfer to the stored water. The boiler volume determines how much hot water is available, while the heat exchanger affects heat-up time and suitability for low temperature systems such as heat pumps.
Always check whether the boiler matches the heat source, pipework, control setup and safety components. Material selection, insulation, anode inspection, sensor position and service accessibility are also important for a durable and maintenance-friendly installation.
Frequently asked questions about indirect boilers
What is an indirect boiler?
An indirect boiler heats domestic hot water via an external heat source. Heat is transferred to the water inside the boiler through a heat exchanger.
When should I choose an indirect boiler?
An indirect boiler is suitable when domestic hot water is prepared with a heat pump, boiler, solar thermal system or another heating system. The boiler is selected based on volume, capacity and heat exchanger.
What is the difference between a steel and stainless steel boiler?
A steel boiler is often used in standard hot water installations with suitable protection, such as an anode provision. A stainless steel boiler differs in material selection and corrosion-resistant properties.
Is an indirect boiler suitable for a heat pump?
Yes, provided the heat exchanger, volume and connections are suitable for the heat pump. A suitable heat exchanger is especially important in low temperature operation.
What should an installer check during installation?
Check connection positions, safety components, expansion provision, sensor placement, anode inspection, pipe diameters, insulation, installation location and the technical documentation of the boiler and heat source.
