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?

How about a flat "terrarium" heater (get from a pet shop or Amazon)
under the tank with a froststat. Only a few 10's of Watts and quid.

Or a 40 watt bulb in a biscuit tin. :-)

bulb failure - freeze - leak. No. Those days are past.

Put 2-off 100W bulbs in series and they'll last forever.
