Immersion Heater timer

    Looking for recommendations for an online immersion heater timer that I can adjust.

    ie switch it on for 10 mins/12mins etc etc.

    I see a few that have 15min/30min options and others with 1 hour boost options. But I want it to be adjustable so that once I figure out how long it needs to be switched on for from cold I know it will switch off after x number of mins. Alternatively one with a thermostat which stays off once the temp is reached. (Not one that switches on and off to maintain a temp)

    That should say in-line not online! So between my regular immersion switch and the element. Also should be capable of handling 20amps.

    I previously had one of these and it worked well. Now replaced with an Eddi though.

    Thanks Jonathan, it’s 13A though, my immersion needs a 20A one plus it’s 15 mins or 30 mins and I would like to tie it down to what it needs to be and no more. (15mins and 20A would actually prob be fine I’m pretty sure)

    if the water is hot after say 17 mins the thermostat will turn off , Provided you had it set for 30mins , the 13mins that are remaining on the timer will still count down ,

    I replaced my immersion switch with something like this?

    What your looking to do prob will only be do-able with the likes of home assistant though.
