Is it OK to put my 500 watt frost heater on a lighting circuit?
It's so that the plastic header tank doesn't freeze.
Just count it as 2 amps for calculating the length of 1.5mm cable allowed?

Electrically fine, but 500w is pretty excessive. You'll boil it. The plastic tank will then collapse, dumping boiling water over someone asleep underneath.

I don't think that the heater is going into the tank!

If it did it'd consume a lot more than 500w.
As a room heater fair enough, but what's the point of 500w into the room versus under 100 to the tank & pipe?
