Thanks everyone ! I am biting the bullet :)

Thanks John... I understand that if a fuse is lower than necessary, it runs the risk of 'blowing' if there is a surge... So in a way, the lowest possible fuse is 'safer' but runs the risk of cutting out.... Am i right? In which case, the current switch I have has 13A fuse anyway. And it's a...

So , either way, a 13 amp fuse is in the original switch. Which I'm guessing is fine. (?) The new timer-switch has also a 13A rating (for a resistive load) and a 13A fuse.

https://www.electricalsafetyfirst.org.uk/guidance/safety-around-the-home/plugs-and-fuses/ says "Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown)." There are various calculations online...

Thanks again Harry :) much appreciated. Do you think the current rating is suitable for the heater? The timer is 13A (3kw) Max resistive.

btw. i've been using the current switch to turn the immersion heater on and off. it's primitive. :) there is no other switch as is.... (just checking!)

Hey Harry, Thank you. The ratings are as above.... Would that not be suitable for the heater do you think? To carry out work on the immersion heater, I would have thought i would switch the fuse off at the main fuse board. Would that be ok ? Also there is a switch on the timer. Would that not...

Hi Terry, Thanks for your reply. I have two switches on the wall. One for the main tank, one for the small tank. I'm aiming to change the one for the main tank. There is no other isolation switch. The timer has a switch embedded (as in the picture) The switch is 13A (3kw) MAx resistive. I...

Hi all, I'm trying to change my simple immersion heater to a timer one. I understand the wiring of neutral and load. But I don't get the earthing. My current switch has a tiny metal strip connecting the earth through the switch. It seems like it's just joining it... however the new timer has an...
