For air heating and radiation heating Backer tubular element are the most popular alternative. Backer manages a large number of production techniques, giving a choice within a wide range of element types. An optimal heat solution of an application is decided by user environment and operating temperature. Backer for example can supply element with an operating temperature of as much as 900°C.
Benefits – Stone heaters
We offer different types of materials for our Stone Heater namely lava, soap stone and granite. No matter which material you choose, this element delivers a high inertia and even distribution of heat. The, so called, sandwich element can either be inserted in the radiator or mounted with fixations. Regardless of the way it is fixated, this element is always class 2. The Stone Heater is highly appretiated for the soft heat it conveys.
- Accumulated effect / high inertia
- Even heat distribution
- Soft heat
- No risk of leakage

Fixing and connection devices
Cost savings can often be made if elements are fitted with connection and attachment devices during manufacturing. We offer several standard solutions. We can also supply special flanges and alternative methods of fixing made completely according to our clients’ specifications. When selecting connection and fixing devices it is often important to bear in mind the size of the series. Do you want to know more about our fixing and connection devices? Please contact us.
Types of cables and wiring
The heating elements can be supplied with connecting wiring which is normally spot welded to the terminal pins. Uninsulated as well as insulated wiring is available. Uninsulated wiring can be fitted with insulating tubing. The joint between the wiring and the terminal pin can also be fitted with insulating tubing if required.
