we need to install fixed heating at our cadet hut, we have 2 x 32amp mcb redundant rings in the buidling with 13amp hard wire points in appropriate places for panel heaters. I'm intending to install 2 x 1.5kw and 2 x 1.25kw on one ring and 3 x 1.25kw dimplex panel heaters on the other ring is this safe to do so or would i be exceeding the limit on the mcb?
