18'' dual safety thermostat
7 Nov 2014
By
, N Yorkshire
"I needed on of these for my hot water tank as the old one was not working and the hot water was getting very very hot to a point it could scald you. So looking at how to fit these couldn't be simpler if you can unscrew 2 wires you can fit one. just remember which wire goes where. the thermostat is well packaged in a strong tube it fitted my tank perfect and does the job"

"This came in a well packed cylinder tube, the controls on the top are easy to read and understand, The two terminals are easy to get to and the grub screws are just right. The unit itself was to replace an aging Thermostat and once power was switched on has run silently and faultless.
In my opinion any one who has a basic knowledge of house hold electrics (which is live and which is neutral) then you can do this job.

Excellent unit
24 Nov 2013
By
, Birmingham
"An excellent unit supplied in a stout cardboard tube, the perfect length to replace an old 18” unit. The probe end was about 0.3mm thinner than the original 5/16” (7.9mm) imperial thermostat, probably to ease insertion.
The plastic head unit was slightly smaller than the original, so an easy fit. The only downside is the lack of any temperature scale markings, instead 7 graduations spread from '–' to '+'. Initially setting mine to 2 divisions below max (+) gave 50 degrees C. One division below max gave a more sensible 60 C.
As others have said, Screwfix’s wide opening hours are a boon if you need to remove the old thermostat to identify its length before heading off for a replacement the same day."

"I replaced one of these as old one had become faulty. Seemed to work fine, it does have a screw dial with numbers indicating temperature so it can be set at the 65 degree normal temp"

"Came very well packaged, was easy to fit and works well. Needs adjustment of the temperature control by trial and error - found optimum setting for our use (about 50C) a quarter way up from minimum."

18" Thermostat - £9.99
14 Aug 2012
By
, Canterbury
"Fitted in 2 minutes, just slide in to your existing 27" immersion heating element, connect your live and thermostat wires and all done.
Quite cheaply made, but then it's just 9.99, so what do you expect. Positive loud clicks give a clear indication it's working on first test.
Left setting as at factory, reckon this must be approx. 60C.
Would have been nice to have a graded temperature scale for adjustment rather than just '-' and '+' with no indication of actual temperature set. However, maximum is 70C, so coming down a quater turn should get a comfortable 60C.
Good value, recommend - Tony."

Essential kit

By
, Fleet Hants
"I was called to a friends house on a recently built property. Super hot water was coming out of all taps, Hot and Cold, a massive scalding risk and something which could be avoided by fitting one of these thermostats and a push button immersion heater timer.I cannot comment on reliability as I've only just fitted it."

Unreliable
29 Aug 2013
By
, Northamptonshire
"Works OK for about 6 months then the poor contact material starts to weld when it switches off so the water temperature slowly drifts up over time until the safety trip cuts the power, no good turning the temp down, once the contacts have welded a few times it's all downhill, I've found the same problem with the immersion heater timer relay contacts, I think that most electrical items switchgear, however much you pay for them are made in the same factory, far far away."
