Temperature control thermostat

[Lilyrose08]

I have been asked to install a 3KW mounted down flow heater with a 7 Day timer next to fuse board and a temperature controlled thermostat in the same room as the heater how do u wire this up do I feed in and out of the 7 day time clock and then take a 3 core from the fused spur to the thermostat any ideas pls help ?

Seems a bit OTT for 1 downflow heater

I'm assuming you want to bring a supply out of the cu as there isn't one available at the moment?
Is the timer an "immersion heater" type, ie 16 or 20 amp rated and surface mounted? If so, then supply from cu into a 13amp FSU, then feed to timer and out from that to heater.
