hp-Technik Heating element 0190051

The hp-Technik Heating element 0190051 is an electric oil preheater component designed for use in burner systems. It operates at a power consumption of 100 W and a supply voltage of 230 V. The element is compatible with shafts of 25–38 mm diameter and is manufactured in Germany. It is intended for installation in hp-Technik B, VB, and NV series oil preheaters.

When selecting a replacement heating element of this type, verify that the power rating and supply voltage match the burner's control circuit. The physical dimensions, including shaft diameter and mounting arrangement, must fit the preheater body without obstructing oil flow. Check the type of connector or flying leads and ensure the sealing gasket or O-ring is in good condition. Always confirm the orientation and mounting before installation, and isolate the electrical supply during the process.

A failed heating element of this kind typically leads to poor fuel atomization, resulting in an unstable flame or burner lockout. This occurs because the oil viscosity remains too high, causing incomplete combustion, sooting, and nozzle coking. To diagnose, check for continuity across the element and inspect for visible damage or signs of overheating. Ensure the electrical connections are secure and the element is properly seated in the preheater body.
