Cylinder stat and pump wiring

[Norn Iron]

Hi Guys

Need some help on a Shed/Workshop heating system, haven't really done much work on heating systems. Basically there is a wood burning fire, a cylinder and a pump. The way they want this wired is that the cylinder stat does it normal job of when it reaches its temp it brings the pump on, but they also want the pump to have a switch so that they can turn it on when they want too.

If anybody can help with this it would be very much appreciated or even if somebody had a wiring diagram they could forward on would help me out big time.

Thanks

That could be done by bringing the supply through a 3 position switch. This would give you the option of having the pump either permantly on permantly off or automatically on via the cylinder stat.

Thanks Sintra so would i just take my supply into this and bring the cylinder stat and pump flexs to this switch aswell? Sorry if this sounds like a silly question but like I said have never wired this sort of system before!

I would fit a basic water heating time clock with override or boost facility.

Just a single channel timeclock with override?

Yes that will do the job.

Is it a back boiler heating the cylinder?
If so, how do you disperse the heat when the pump is not running? (stop it boiling)

Hi Boydy yeah its a back boiler, My understanding is that the pump will run when the cylinder stat reaches the cut out temp and pump the heat round, But they also want it so that they can switch the pump on whenever they want to I dont know why but am also unsure how to wire this correctly!

Am I right in thinking that this is gonna need wired like an ordinary heating system as it is fed by a log burner back boiler and there are 6 radiators on the system?
