I was going to use some of those gold coloured power resistors.

Yes :-) Just gave the colour so that people would recognise them. The
green ones cannot take such a high load and are slightly inductive.

I've got a 500W green one.

Just what I was after. I'll wire this lot up into a small box with two

Good luck.
That's why I like the immersion heater, it's about the right rating, and
very cheap.
