how to replace an immersion heater?

[Phil]

I always get the plumber to do them

so do i, i would end up smashing the tank and i don`t do water

if you find its a nightmare to get it moving, I found applying a little heat using a gas torch works wonders. Only for a few seconds and then try again. I've heard short sharp blows with a hammer on the spanner helps but it never has with me. Keeping the tank full to "crack" the seal is a good tip otherwise as already stated you could rip the tank and that's just not good

never had a problem with sharp taps with hammer. worst i could do would be to wet a few things. blowlamps , now that's different. i could set the house on fire!
