coffee machine on a timer

[moe]

the coffe machine has to go on a timer to warm up before the shop opens ready for business

This is the sort of thing I was thinking of: Caff Italia Professional Coffee Machines: Ne Gaggia Deco Bar vintage line Super OFFER, Gaggia Professional Coffee Machines, gaggia-deco

thanks for all the replys. going to go with the contactor and timer but would do with a little on contecting it etc.. not done one of these before..

They're quite simple really.
You break the cable feeding the coffee machine where convenient, put the cable away into the appropriate sides of the contactor, may have to extend the cable to do this.
Take an unswitched feed for power to the timer, and then a switched feed back to the contactor to the appropriate terminals.
Your timer is going to have to be suitable to switch whatever voltage is required to operate the contactor.

I would be morally opposed to putting a timer on a coffee machine. Certain critical appliances should be left on continuously in case of an emergency

Rather than putting a timer and a new contactor on the electrical supply why not look at installing a timer internally in the machine and using it to break the supply to the existing heater element control contactor. You can easily do this at the pressure switch if it's a cappuccino machine. They can then just leave the machine on all night and it won't consume power (apart from the odd indicator lamp maybe).

The problem is these machines can cost in excess of £5000 and once you tamper with the internal wiring, your warranty is void.

Good point. It makes sense electrically but might not be suitable under warranty conditions

have you got any examples of these internal timers?? not going to use them now but maybe in the future on older machines

Other problem is that the EHO may not be happy about the coffee machine turning itself on while unattended let's not forget these things are pressure vessels after all, there was a case before Xmas of a detonating coffee machine in a costa somewhere u should have seen the mess it made and it landed a few in A&E

Maybe worth the client asking the question

good point will defo ask the question..

Any DIN mount timer with a battery reserve would be suitable. They come the same size as a circuit breaker generally, you would need to find somewhere suitable to mount it.

Commercial coffee machines are rated at continuous use and have electrical and mechanical failsafes built in to prevent them 'detonating'. I think there would only be a safety issue if you were bypassing or reducing the effectiveness of one of these protection systems. Regulations vary from place to place though so it would be worth checking.

It was a Tesco store and you're right, it looked like a bomb had exploded, every little helps.....

Were dealing with EHO not HSE the failsafe is a pressure relief valve if they scale or corrode they are less effective, yes rated for continuous use but that's not in question it's the issue of this thing turning on while unattended there are some considerable regs regarding pressure vessels and water boilers

I don't understand why you think an internally installed timer would be more likely to result in the machine being on and unattended than an externally fitted timer or are you saying it would be illegal either way to switch the machine on in the morning to warm up if it was before people arrived? Please bear with me, I'm not a complete moron, I'm just not familiar with the UK regulations.
