I am about to purchase an AV receiver to go with my TV and with it I'm looking for an entertainment unit to put everything in.
Is there a minimum amount of room the receiver needs for ventilation? One unit I saw (and like) would leave a centimetre either side of a receiver, ten or more to the back with an open front and literally one or two millimetres above it. Is this not recommended?

It would most likely me a Yamaha or Onkyo receiver, low-mid range.

pleanty of room on the top where the vent holes are located. My center was closed in the back but I removed the cover. Remember that heat travels up.

I would call the manufacturer and find out what they recomend. You might find this info in the user manual, which can be downloaded in most cases so you can read it before you go out and buy it.

Personally, I would not be comfortable with that little space you noted. Example, my Dish network HD-DVR box was originally in a cabinet (similar open space around it that you mentioned) and after a while it got so hot I could barely keep my hand on it. Since I changed my setup it is sitting wide open on a new tv stand and does not get anywhere close to being that hot.

If you do decide to have limited space around your av equipment, I would have some sort of fan on them for cooling. The moving air should also help keep dust from settling on and in the reciever. Dust and heat are not a good combination.

Hope that helps.

I looked up the Yamaha manual and it says, "Allow ventilation space of at least 30 cm on the top, 20 cm on the left and right, and 20 cm on the back of this unit."
Onkyo says, "Leave 20 cm (8") of free space at the top and sides
and 10 cm (4") at the rear. The rear edge of the shelf
or board above the apparatus shall be set 10 cm (4")
away from the rear panel or wall, creating a flue-like
gap for warm air to escape."

This seems VERY excessive.

I can manage the 10cm at the back with no problem, just on top, depending on the receiver, I can get maximum an inch and maybe half an inch on each side. The front is all open.

Does anyone have a similar set-up or had a similar one that can comment on how things went?

Your basicly going to put your reciever in a box. With that little of space on top and sides heat is going to build up excessivly. And over time dust WILL settle on the internal circuits, which will not let the heat to escape. There is a reason why the manufactuer has those measurements stated. I think you could be just asking for trouble. But then again it could work just fine... I just would not do it myself. Heat and electronic equipment are not a good combination.

I am going to assume you want some advice on what to do about your red hot DISH box? I can tell you from my experience that is needs more room to breath. Like I posted, mine is in the open now and i can leave my hand on it all day and not get burned. (yes it got hot enough to cause a burn before)

If you can't move it, I would try and get one of those laptop coolers. The kind you set the laptop on top of. It has built in fans and may give you the cooling you need. That's what I was going to try before I got all new gear.

Lemme know how it works if you try it.

besides frying an egg on it, the overheating of the set will usually cause the TV to shut down. See lengthy thread about the MITSHU air-flow problems on this forum. Ventilation of all electronics a serious issue. Buy A/V furniture with CAUTION, so as not to shorten the life-span of your costly components.

Best to all,

I got these two from WalMart for $59.96 each in the Dayton, Ohio area.
The TV stand can hold up to 340lbs., 240lbs top shelf/ 100lbs. bottom shelf/ 20lbs. middle shelf.
The A/V rack will hold up to 4 electronic components.

highly recommend a dedicated A/V rack for proper ventilation of your receiver and other components.

Just a thought,
