Tesla Titanium Immersion Heater 14" is rated 3.9 out of 5 by 22.
Rated 4 out of 5 by from It made the job easy. My immersion heater expired on Friday evening (8th February). I went to Screwfix online and found exactly what I wanted. I ordered and paid for it online and then drove to collect it. In all it took me half an hour to buy online and then drive there to collect. It's easy to fit and works well. I don't need to go anywhere else for replacements.

Rated 1 out of 5 by from Leaky ! Installed this unit as a replacement in an unvented system. Once installed and heated all the water, I discovered a water leak from both solder positions on the element, I rang Tesla to check if it was suitable for my tank and was told it should be fine. Apparently they are factory tested up to 6bar. Didn’t seem too bothered, (they’ve probably heard it before) Very annoyed now have to do a 45 min round trip down to screwfix to get it swapped and waste 150 Ltrs of hot water!

Rated 4 out of 5 by from Urgently needed on site! Needed a replacement urgently for a stroppy customer despite it never being used. Nearest store was under a mile away, dead easy to click n collect, back to site and bingo. Job done.

Rated 5 out of 5 by from Perfect These last and last far outperforming normal heater elements, it's worth the extra cost for peace of mind and reliability.

Rated 4 out of 5 by from Early days, but great so far! Installed this over the weekend, easy enough to fit and no issues. It has been working well so far, well worth going to the 14" if your tank can support it, so much faster to heat up than the previous one. We have very hard water here, so that will test the titanium over time, but it seems to be up to the challenge. Top tip, please make sure you clean all the residue from the old one off your connection, I didn't do quite a good enough job and it leaked (very slightly) when first refilled. Rectified this and no problems since.

Rated 1 out of 5 by from 2months and blown every seam Fitted early December2016 and by the end of Jan 2017 it had caused a short circuit blowing the trip. Removed teh unit as it was not the thermo element blowing, and found the seams almost 100% of teh way blown apart and split. by almost 100% I'd say 95% or more. I'd read some other negative reviews of this item and ignored them at my peril. The time to replace the unit and unhappy customer (in this case family) far outstrips teh small saving. Buy better quality as this is rubbish.
