I don't know what u mean by duel element?, when I think the water is hot ,I fill the bath only to find out its not hot all the way through, starts going cold after about 15 - 20 cm hot water
Copper colour with a green foam wrapper around it, before last night my bath was full of hot water and still had enough to wash up, also I cant here the tank filling up like I used too.
Hi I am looking for some advice, my immersion heater was working fine, heat a full tank in half a hour, now when I put the immersion on it will only heat about 2ft water then the rest is cold, please help
