Electric heating element TERMA WETS104K Split Class I 345 mm 400 W

TERMA WETS104K Split Class I 345 mm 400 W is an electric heating element intended for installation in compatible TERMA towel radiators and convectors. With a 345 mm immersion length and a rated power of 400 W, this split heating element provides electric heating where central heating is absent or when additional heat is required. The device is built to Class I protection standards and is designed for fixed installation into radiators that accept split elements of this size.

Advantages

The split design allows installation without draining the radiator completely, simplifying maintenance and replacement. A 400 W power rating gives reliable, steady heat output suitable for small to medium bathrooms or for supplemental heating in living spaces. Class I protection indicates a grounded design that meets standard safety requirements for electrically powered radiator elements.

Suitable for

• Electric heating of towel radiators in bathrooms where central heating is unavailable or turned off
• Supplemental heating in small to medium-sized rooms
• Applications requiring a split element to allow easier replacement or installation without full system drainage

When it may not be suitable

This heating element is intended to fit radiators that accept split Class I elements with an immersion length of 345 mm; it may not fit radiators with different thread types, mounting positions, or immersion lengths. It is not designed for use in systems that require Class II (double insulated) elements or for radiators specified for higher power ratings than 400 W.

Key specifications

• Type: Split electric heating element
• Protection class: Class I (grounded)
• Immersion length: 345 mm
• Power output: 400 W
• Intended application: towel radiators and convectors

How to use

Install the TERMA split heating element into a compatible radiator according to the radiator manufacturer’s instructions and local electrical regulations. The split design requires connection of the electrical components and securing the element into the radiator’s threaded opening; for safety, electrical connection and grounding must be performed by a qualified electrician. After installation, verify tightness at the connection and restore any heating medium if the radiator was partially drained. Follow any specific commissioning steps provided by TERMA for correct operation.

What to consider before purchase

• Verify radiator compatibility with a split Class I element and a 345 mm immersion length
• Confirm the radiator’s power requirements and whether 400 W is sufficient for the intended space
• Ensure local electrical standards accept a Class I grounded heating element and that a qualified electrician is available for installation

Usage recommendations

For safe and effective use, have a qualified electrician perform the electrical connection and grounding. Confirm mechanical fit and thread type before purchase and test the installation for leaks and correct operation after fitting. Use the element as a supplemental or standalone heater in accordance with the radiator manufacturer’s guidance.
