Rated 4 out of 5 by from telsa 27"immersion element i purchase just over 18 months ago but this has now failed, my immersion heater only gets switched on now and again [ its otherwise heated using the gas] so I am surprised to find that this element has failed so quickly , previous one lasted 20 years..i live in a soft water area so though the copper one would be suffice

Rated 1 out of 5 by from Poor quality The thermostat is very poor quality and not able to withstand the current requirement. Within 5 months the black cable had corroded and burnt through. Wont be buying again. Would not recommend.

Rated 5 out of 5 by from Works fine - good value Bought this at 7am on a Friday morning to replace our 40(?) year old one which tripped the mains. Fitted easily and wired up following the clear instructions. Piece of cake fitting - don't discuss removal of the old one though! Works well . I don't know if it will last 40 years though! I little realised how much I would miss hot water!

Rated 3 out of 5 by from Thermostat failed Thermostat failed within two weeks. Exchange no problem but still took a few hours from my busy day. Not happy with the quality but time will tell if it's just a one off. I can't recommend a product that failed after such a short period.

Rated 4 out of 5 by from good product fitted this yesterday, nice & easy to fit just need to be careful not to put too much ptfe on the threads as it then becomes difficult to line the threads up. Cant comment on reliability

Rated 4 out of 5 by from Immersion Heater First - The sales assistant was exceptional and went the extra mile to ensure that I was buying the right thing - he was a credit to Screwfix Northanmpton. Second - I have marked it all as 4* because I actually only ended up needing the 'thermostat' part to repair my heater. Cannot really comment on suitability for hard/soft water and/or longevity etc. I am in the middle of a 2 weekend boiler and 17 radiator valve change and having drained the system - flushed - and refilled then bled found my boiler would not restart. Too late I discovered at 7pm on Saturday evening my Immersion Heater was not working either. Sunday morning get a cheap replacement to have hot water for the week. Up to local Screwfix and got lucky with a rare creature - a helpful and genuine sales assistant - 2 hours later I had a tank of hot water. Well done Screwfix - very impressive.
