Can you buy a storage heater rated 3400w @ 230v though?
If you ignore the temperature coefficient of the element, 3400w @ 240v equates to 3400 x (230²/240²) = 3122w @ 230v.
I expect the makers of such items don't want to suddenly start offering a 3122w heater when someone else is offering a 3400w version as it doesn't sound as good on the sales blur, they may however state the voltage over a range of 220v-240v, the larger voltage being the applicable one for design current calcs.

Well i am totally confused no one seems to have answered my question just all calculation talk. the cable i used is round heat resistant three core 1.5.Do i understand that at worst the heater will have a load of 16amp and i have a 15amp switch in the cu would that cause the fuse to blow after five weeks.ps the fuse is the round glass type
