[QUOTE="kme, post: 367994, member: 113"] Both helpful - thanks........( I think) I`ve now got a 29,600 Kj figure, and a headache. I think the losses from the open surface, and unlagged sides of the tank, plus the steel pipework & pump, will be quite substantiative. [I] I think [/I] that this means that, if I allow a 30 min heatup period, from 20 degrees, to 88 degrees, I`d need 16.45KW of power. If that`s the case - the woeful 6KW element currently fitted is going to have issues It doesn`t have to be precise - but I don`t want to size & install a radial for this thing, and find I`m waaaaaaaaaaay off in my loadings. I`m thinking of filling it with water, and seeing what it`ll do in an hour or two.... The first thing is getting it to temp..... Then it must be able to keep it there, as well...................
