We need to do a replacement for a 25 year old Jenn Air unit.

I've been reading recently that newer wall ovens blow a lot more hot air into the kitchen than older models did. Is this true? We also have a Wolf gas range and tend to use our electric wall oven in the summer rather than the Wolf since that puts so much heat into the kitchen. Do all manufacturers' ovens put out the same amount of heat in to the kitchen, or do some emit less heat?

Another question: Which manufacturers of wall ovens are proven to be the best for the combination of quality, pricing and reliability? We want quality but since this is a secondary oven do not need a top of the line wall oven.

Thanks.
