Energy Saving 15 Minute to 2 Hour Electronic Boost Timer for Immersion/Room Heater

Great service and product it was a like for like swap easy to install

This works very well instead of the standard on off switch our hot water storage had. Set the time and it switches offEasy to fit with clear instructionsThe blue light is ver bright in the dark house, so we keep the door closed.

This immersion switch is the best way to control the use of your heater as you have control over the time that the water heater is being used. A good purchase.

Just push the required time and get presto it works! Wired into my immersion and I love it's simplicity.Item sadly failed after a couple of months but was replaced, for which I am very grateful

Nice bit of kit, has benefited from old reviews and is now very clear how to use and install. Designers must be proud of themselves. I used a 16mm surface pattress because I couldn't find a 12mm, but that was just as well.Like many electronic timing devices, it has an unnecessarily aggressive bright blue light so I didn't install in bedroom as first thought but that's a plus.Switch is a bit clunky and noisy. You wouldn't call it discreet.Amused that it is controlled by a quartz timer accurate to +/- 1 second.

Great product just what I needed easy to install

A simple to use electronic timer which is well laid out and easy to use. Allows you to make just the amount of hot water you need. It prevents you leaving on immersion heater due to forgetfulness.

Not fit for purpose.Contacts are too small to fit the wires into.
