Tesla Incoloy Immersion Heater 14" is rated 4.4 out of 5 by 16.
Rated 4 out of 5 by from Silent Night As a DIY man it fitted easily pleased to say. Thought I must have made a mistake in the wiring because when switched on it made no sound at all. We're on Economy Seven so it works through the night and the silence compared with the old one was a bonus. Only installed yesterday so now I hope it has a long life. Pleased.

Rated 5 out of 5 by from Worth the Extra for incoloy The old copper immersion element had almost dissolved when I removed it. The thermostat pocket just fell off, so buying the incoloy version is very much in the customers interest and worth the small extra amount it costs. The customer is delighted as they only have electric heating.

Rated 3 out of 5 by from not suitable for unvented Generally unvented cylinders have a 1 3/4 BSP thread not the 2 1/4BSP that this comes with. Screwfix seem to not supply the unvented cylinder version.

Rated 3 out of 5 by from Wrong Size Be careful - this has a 2 1/2" boss - not stated on website. Some cylinders have 1 3/4" boss. Very frustrating to find you've got the wrong size after draining the cylinder!
