Hello Sue, my name is George..The heat given out by the appliances would depend on a number of factors:1. Are the appliances next to eachother2. Do the appliance have sufficient cavities surrounding them3. Do the appliances have rear venting or front venting cooling fansThe residual heat you feel from the ovens will not only depend on the oven specification and fitting, but will be influenced by the size of the room, the filling of that room, the amount of doors, the amount of windows, and the amount of available, or lack of, ventilation.Kitchen designers/fitters should take all this into account at the design stage... Air bricks and electric vents or extractors can be fitted to reduce heat build-upPlease rate the assistance given by me & kindly be patient whilst awaiting any responses from me as I'm not constantly available.
The ovens sited one above the other (the combi oven above the Aqua-assist). The heat is not residual - which is the heat given off as the ovens cool down - it is constant during the cooking process. The two ovens are in a housing - as is pretty standard these days. My sister's two ovens are also identically sited.
I said in my enquiry that my kitchen is small - so not sure why you are saying that the heat emission is influenced by the size of the room.
It is not a question of "heat build up" it is an issue of heat being emitted from the front vents of the oven above the oven doors.
You ask if the ovens are front venting or rear venting - is there a choice with Neff or are you unfamiliar with these appliances?
Thank you for your response Sue,If you are referring to the heat blown from the oven whilst the oven door is shut, then the heat given off by the oven is a residue of the heat created during the cooking process which builds-up in the cavity of the oven and is then dispersed via either a rear venting circular fan, or a front venting top-mounted tangential fan inside the oven cavity.I spoke of front and rear vented ovens as I didn't know which ovens you had... Some ovens are front vented above the door, and some are vented from the rear by way of a large fan into the cavity... Some ovens have both types on the same oven.. Neff have both types available, but you would need to ask Neff with regard to the inclusion of either in their current models.The reason that I alluded to the heat emission being influenced by the size of the room was that you needed to be aware that any differences between the size of your kitchen and that of your sisters will make a marked difference with regard to heat exposure.. Notwithstanding this, in a small kitchen you are virtually forced to walk closer to the source of the escaping heat.As a point only to respond to your question, I work on Neff appliances on a very regular basis.I hope this has answered your questions well enough for you... Nevertheless, please feel free to respond further should you need.with kind regardGeorge
Yes, well although it is a small kitchen it is not a case of how close I walk near the ovens, as we are not just talking about "escaping heat" here. Perhaps when I said that it was like standing in front of two fan heaters, you didn't understand what that meant. If one stands in front of my ovens, it is like standing in front of fan heaters on full power (not far short of a hairdryer's output). I have made a comparison standing in front of my sister's Neff ovens and although there is some warm air output, it is at an acceptable level.
What I really need to know from someone who deals with Neff appliances on a regular basis, is whether or not this is an unusual phenomena. Apart from telling me that some ovens have front vents, some rear, and some both, you have not indicated whether the issue I currently have is something you have come across before. That is the question I would really like an answer to and also whether the manner in which my ovens are operating should be considered acceptable.
Thank you for the further information. Could you please let me know in what way it could be "potentially harmful".
Thank you for such a speedy response. My husband is already waiting to hear back from the company responsible for the installation, and I think that the further information you have given me will assist us in getting this properly investigated.
Thank you again.
Just finally, can you please let me know where you are based in the UK.
Thank you George.
We have a Neff engineer coming here tomorrow. I'll let you know what the outcome is.
