Dual Safety Thermostat 18" is rated 4.173913043478261 out of 5 by 46.
Rated 4 out of 5 by from Worth the money, easy to fit Bought this to replace a previous failed unit (along with a new heatproof cable). Easy to fit, just a small screwdriver needed once the power has been isolated and the cover has been removed from the immersion heater. Needed to clear sufficient space above the immersion heater in order to remove the old and install this as it's replacement. The adjustment of the temperature was simple, the unit has markings and subdivisions every 5 degrees.

Rated 5 out of 5 by from Good value Appears good quality for the price and time will tell if it lasts, but initial thoughts are that its a good product. Easy to fit but check the length of the old thermostat before buying as you need the same size.

Rated 2 out of 5 by from Q/C needs sorting out. Now on the third one in 5 years. I am a glutton for punishment. At least this went within warranty and Screwfix changed promptly. The temp settings markings are very poorly printed and the moulding around the the rest button was poor as the button was covered by plastic flashing from the moulding process. The previous two failed because one wouldn't allow the temp to get above luke-warm whilst the most recent couldn't be turned down and the water was scalding. The original thermostat that came with the immersion heater lasted nearly 20 years. Third time lucky?

Rated 3 out of 5 by from easy to fit Replaced the thermostat easily enough, works fine, changed the cable which connected to it as old and brittle and covering cracking, worth looking at before you re-wire it
