Two 4kw space heaters on one timer

[Leah]

I'm adding some 4kw space heaters and towel rail to existing ring mains (have elected not to run a separate circuit as they are only to be used rarely and mostly at different times to top up a wood burning stove that heats most of the property), the main bedroom will have two of these heaters and the client wants them both to run off one timer, they have purchased the same timer that I've used on their immersion (rated at 16amps, do not have make and model, it's pretty obscure anyway), I'd be happy to use this if there where one after each spur but have reservations about running the two heaters off of it.
Can someone please advise if my concerns are founded and if so what a better alternative might be, and if I can use the existing timer how best to configure.

Can you not fit a contactor?

Only option is really a contactor if you want them both together

An Leah if you require a drawing Sintra has some fancy looking drawings which are really clear and easy to follow, I'm sure he wouldn't mind posting it up if you ask him nicely
