I'm currently looking at having my kitchen redone and in the process I'll be replacing my crappy oven. My current oven is 2400 watts and runs on the downstairs ring main. I don't have a dedicated cooker circuit.

I've found a Bosch oven I like the look of which is stated at 2900 watts. This is about 12.5amps so is this OK to run on the same ring main? The manual states it needs a 16 amp fuse. Obviously a competent person will be installing this, I just want to get an idea of what needs doing before they come in.
 
Yeh, that's what I thought but the people I've had in to plan our kitchen have said a 13 amp one would just plug straight in.
 
2900W will just plug straight in...

A regular plug in kettle or heater can be more powerful than that.
 
If you're having the kitchen redone I'd have a new circuit put in anyway.

I've not got around to the kitchen yet and if we turn on all the appliances it will trip the fuse, let alone the oven too - 4-slice toaster, kettle, coffee maker, dishwasher, tumble dryer. It mounts up really quickly
 
General rule of thumb is if it comes with a plug top in you can plug it in, if not it will require a dedicated circuit.

At 12.6 Amps it is on the limit, plus running a final ring main at this could potentially give you volt drop issues effecting other equipment etc.
 
It will plug in, its less than 3kw. Having a dedicated circuit is nice, but I'd weigh up the cost of installing one. If you have a separate ring for the kitchen it shouldn't be a problem at all though. I'd recommend a dedicated circuit if all of down stairs is running on the same ring myself.

You should maybe not be giving advice on things like this, the maximum rating for a BS1362 fuse is 13amp. So while yes you are correct, you could possibly get another .4amps out of it your statement implies more :)
 
This is the oven I was looking at.. Bosch HBA13B160B. It's an oven grill combo. The kitchen designer is saying to just get a lower rated 13amp oven and not bother with a new circuit (he's trying to flog me CDA appliances). Any decent ovens seem to be more than this and I'd rather have a good one or I'll be annoyed with it again in the future.

How much am I looking at to run a new cooker circuit? The consumer unit isn't far from the kitchen but routing the cable will be a pain. I'd like to do it properly, but I'd also like to do it as cheaply as possible as I'll be spending out enough on new appliances and kitchen!

That oven is just over 12A at maximum rated load, it'll be fine.

Id have a dedicated circuit too but the fact is that he can plug it in if he wants.
 
There is plenty of space in the consumer unit, it's more the pain of routing the cable through the walls/floor to get it into the kitchen!
 
Wouldn't cost much my past 3 jobs have been £75/100/250(parts on top of about £60) the last one was only that much because it was an absolute pittance to route it. Customer didn't want it going direct and wanted it routed round a few rooms instead :confused:.

I'd go with a circuit just so it's future proofed should the oven get replaced its cleaner and cheaper to install a new run when it's in a rebuild.

Edit: the rating is only 12amp and you'll never use the grill and oven simultaneously so the draw will be lower. Unless things have changed and I wasn't told 2900w is based on everything used at full draw which won't happen.

Ah fair enough, I was figuring it would be about £500. For that kind of money I'll just get it sorted properly!

Haha, I've not had any electrical work done in this house since I bought it and always lived in rented houses before that so no idea how much these things cost! The way the guy from the kitchen company was going on, he made it sound like a huge cost. Also if I get a proper circuit put in, I can go for the better pyrolytic I liked the look of.
 
Well if you get them to do it there's a good chance they're going to subcontract and cream a nice profit on top of what the sparky charges. Obviously there's varience in pricing between areas but I wouldn't expect it to be that much more than what I charge. If you were in London then you could be looking at that sort of money but for a couple hours job including testing I would feel guilty charging that much.

It's always good to splash on an oven. The house I'm in at the moment has an oven older than me and it's still going strong. Top of the range in those days.

Only other thing I could want would be an induction hob those things are so cool!

Yeh, I spend a lot of time in the kitchen, especially now we've got a dog and he lives in there. My current kitchen was put in for a budget to bring it up to scratch to sell the house. The hob and oven wind me up no end so I really wanted good ones as I've suffered on for about 6 years with these. I was definitely looking at induction, even managed to convince the missus they weren't witchcraft (not that she uses it anyway). Liverpool prices are usually pretty decent but I was going to get whichever company I went for to do all the work just to give me less hassle.
