Twelve by seven inches sounds too large. Why is it so large that it takes up nearly the whole hot side of the enclosure? I was interested but not when the size of it sunk in.

Mine is 10 1/2 inches by 6 inches. It is a triangle shape. It does not take up that much space and you can bury it in the mulch.

clarify your question. I suspect you are overfilling the tank. You must allow "head room" so you can pump the tank up, filling the space with air.

I have the large one and it is about 12 & 1/2 inch inside, 14 & 1/2 outside. Don't get the small one it is not big enough.

The damned thing is huge, if you are packing go with something much smaller. This sucker's for car camping. (The power port in the side wall is a dead giveaway for that!)

Its big (about 6 inches circumference at the bottom so its quite big all the way around, and is bigger as it in the middle section) and not good looking and it sits out in the open. It really reminds me of some of those reverse osmosis canisters that sit inside the cabinet under the sink. But I think worth it as an extra precaution.

If this were to be a second outdoor enclosure with lots of climbing and basking spaces, as well as a shaded area and watering place, it would be.As a primary enclosure, the other responders are correct: they need wider enclosures.:)

All I can say is it is much larger than the one I used to have, almost too large. I have never filled it all the way up even with a doubled recipe. I have had it on for around 8 hours at a time.

The cause of this may be that you are expecting to fill too large of an area. What size is the room you are listening in?

I noticed it seemed hot to me too. But my birds don't sit on it that long, just long enough to warm up. I have a small portable heater in their room in the winter which they seem to like.

I don't know why, I remember thinking the same thing myself. I just measured this one and it's 7 inches thick.

It may be too big and hot. I have only used it for larger wire connections and it works well.

It's too big for the 2-4 ft enclosures, you need at least a 3 x 5 to fit it

I would look for a different width product. This one is only 20"... If you centered it in your 30" space, you'd have 5" on each side that would be unheated. While the heat does spread a little bit, you'd still feel cold spots where there was no wire... it would not spread 5"

well the product is 17-12-12. sounds like your putting it in some kind of enclosure. this thing has 2 fans in the back for cooling. its 12 inches high and 12 wideyour going to want to leave about 3 inches of clearance on top and 3 on each side at least. this thing has to be able to cool it self off and you really dont want to get in the way of that. leave at least 6 inches of room in the back where the fans are for cooling.

it gets very hot, sides, top and front. the back gets extremly hot. the back has stops to keep it away from the wall but i would advise to keep it a little further away.

You should also have plenty of room between top and another surface, it gives off heat. Sad thing is all toaster ovens suffer from this, figured someone would have fixed that but it is a great oven.

I ended up sending this back, it was too big and blew the circuit breaker. So I never had it up and running at full heat. Sorry
