As I said Jazz - I had them in stock.

My workshop gets cold in the winter, do you reckon I could wire some stepper motors up to the mains and use them as heaters, I have a box of high inductance Astrosyn jobbies ?

I wouldn't expect an AC servo to work on DC, cos I know how servos work and I know how a relay works, it is just a solenoid. The first burn-out was caused by excess current and I will put my hand up to not thinking about it. The second burn-out was because the furnace owner replaced the relay with like.

We put in another AC relay to keep the furnace on over the weekend, but it will be replaced by a DC block on Monday.

If you want to see the control panel it is monitored by an IP camera
