Heating Rods
Heating rods are used for the electrical heating of water in storage tanks, buffer tanks, or suitable heating and hot water systems.
In this category, you will find electric heating rods and matching components for storage technology, auxiliary heating, system expansion, and technical system modernization.
Using PV with heating rods – briefly explained
Direct PV connection
The PV modules are connected directly to the heating rod or the associated PV controller. The generated PV direct current is used immediately for heat generation.
External control required
The heating rod is suitable for using PV power, but requires external control for automatic surplus operation. This detects available PV surplus and controls the heating rod accordingly. A direct connection to PV modules is not intended.
System integration only
The heating rod has no built-in PV control or special PV interface. It can be integrated into an energy management system as an electrical consumer via a professionally planned control and power circuit.
Note: The required control and connection technology depends on the respective heating rod and the existing PV system.

Heating rods for storage technology and electric reheating
Heating rods are electric heating elements that can be integrated into suitable storage tanks, buffer tanks, or hot water tanks. Depending on the system, they serve as auxiliary heating, reheating, frost protection, or technical addition within an existing heating or hot water system. Especially in storage technology, heating rods can be a useful component when electric heat is to be specifically introduced into an existing storage tank.
Advantages of suitable heating rods
- electric heating of water in suitable storage and heating systems
- usable as auxiliary or reheating depending on the system concept
- suitable addition for buffer tanks, hot water tanks, and storage technology
- various designs for different connections and installation situations
- technical option for integration into modern system concepts, for example with control or PV environment
Areas of application and target groups
Heating rods are suitable for homeowners, DIY enthusiasts, HVAC-related buyers, and technically interested end customers who want to expand an existing storage system or prepare an electric reheating option. Typical areas of application are buffer tanks, hot water tanks, storage technology in heating systems, renovations, and technical additions in systems with multiple heat generators. It is important that the heating rod, storage tank, connection, electrical power, and control match each other.
Important selection criteria
When selecting a heating rod, the connection size, installation length, electrical voltage, power output, control, thermostat function, safety features, material, storage tank compatibility, and installation situation should be checked. The question of whether the heating rod is intended for heating water, drinking water, or a specific type of storage tank is also decisive. Electrical components must not be selected solely based on appearance or thread, but must technically match the system.
Proper sizing and installation are particularly important, as heating rods can affect both water-carrying and electrical system areas. Planning, electrical protection, connection, and testing should be carried out by qualified specialist companies. Suitable related categories are Storage tank technology, Buffer tanks, Hot water tanks and Heating accessories & system technology.
Frequently asked questions about heating rods
What is a heating rod?
A heating rod is an electric heating element that is installed in suitable storage tanks or water-bearing systems to heat water electrically.
What are heating rods used for?
Depending on the system, heating rods are used as auxiliary heating, post-heating, frost protection, or for targeted heating of stored water.
Does every heating rod fit into every storage tank?
No, the heating rod and storage tank must be technically compatible. The connection size, installation length, material, medium, power output, and the storage tank manufacturer's specifications are important.
Can a heating rod be combined with photovoltaics?
Depending on the system concept, a heating rod can be integrated into a PV environment. For this, the control system, electrical power, storage tank, and surplus logic must be planned accordingly.
Which selection criteria are important for heating rods?
Important are the electrical power, voltage, connection thread, installation length, thermostat or control, safety functions, material, and suitability for the respective storage tank.
Should a heating rod be installed by a professional?
Yes, heating rods affect water-carrying and electrical system areas. Installation, electrical protection, connection, and functional testing should be carried out by a professional.
