Think I maybe dragging this one up again but I've got a query that I haven't found an answer to after scanning through the last 14 pages. If an immersion heater is permitted to be on a 13A FCU then what is wrong with having other equipment on the circuit?
For example, what about a small electric underfloor heating system (about 400w for the sake of argument). We already know that the circuit is rated at 16A, the cable will handle this current and then some and the total demand will be 14.78A at a supply voltage of 230V. Can anyone supply me with a regulation that states this is not allowed. Also I tend to find that in most modern houses the immersion supply is there purely as a back up in the event of a boiler failure which adds more reasons as to why supplying additional items from this supply should be acceptable practice.
