A customer of mine wants an air curtain heater above a door but he also wants an isolating switch at light switch height, any ideas?

Plenty, not many of them printable, and all of them a variation on "tell him not to be such a **** and try having a proper door instead."

he has got a storage heater thats up the creek so i think this is another option

When he says isolating switch, does he just mean a way to turn it on and off, as if so then a contactor is the answer. If he actually wants an isolating switch for maintenance etc, then it would obviously depend on how powerful the air curtain heater is, if it's e.g. a 3kw thing, then a simple 20A DP switch would be fine, if it's a lot more, you might need a more industrial solution...

Why not fix the storage heater

 

[Click-Sure]

Use a DP 'cooker' switch?

If its 3ph then consider a 4-pole roto-lock isolator, even if its single phase, consider one, makes life a lot easier to lock-off the supply for servicing.

An air curtain will cost a hell of a lot more money to run. Since most of it goes out the door at ~20p/kw (if on an eco7 tarrif).

I did see an article recently titled

"Study shows Dimplex air curtains can save energy"

Well , they would say that, wouldn't they.

Assuming the isolating switch is to operate it, like everything else today, air curtains are available with remote control. See here

If the isolation switch is to er...isolate it, I don't imagine this will help you much.
