Tesla Incoloy Immersion Heater 11" is rated 4.0 out of 5 by 10.
Rated 2 out of 5 by from Worked well for 3 months Brought this in June and fitted it mid July due to a 13 year old one giving in, easy to change and fit if you know the basics (I'm a qualified water plumber, not gas). this new one kept the water on standby hot throughout the day set at 55 degrees, not at the full 70 degrees it can go up to. On October 13th however, it no longer works, water does not heat up, ran a tester on it and there was power coming in to the thermostat but no power passing through it, I have an emersion heater so that required 2 of these, the other one packed in 4 days after the first one. Just over 3 Months after fitting. Due to not being able find the receipt and not having a screwfix account at the time, I couldn't return these, a mistake I won't make again as I now have an account to keep a record of the items I have brought. I don't recommend these at all.

Rated 5 out of 5 by from Good buy Easy to fit and very quite. We had an old copper element before this one is much better and well worth the extra few pounds.

Rated 5 out of 5 by from Corsion resistant element These Incaoly elements are more corrosion resistant than the basic copper type so are better value overall. Dont forget to buy an Immersion spanner , if you dont have one already. I find that the "box spanner" type give a better grip and are easier to use. Its not the fitting thats a problem but the removal, if you have one to take out.

Rated 3 out of 5 by from Works but not so clever This element works fine as you'd expect an immersion element to work. The thermostat however, although it has calibration marks on its dial has no numbers so which way is high and which way is low is trial and error!!! I followed the configuration of all other thermostats and got lucky.
