All I said is 8ºF difference in ambient temps is almost impossible in the space inside a box. THINK logically how is it possible the air temp from the left and right is that different?

I am very open minded I read and ask questions. I did send Bob 3 emails and he didn't respond so I sent one to Reptile radiator and had an interesting discussion. Yes they confirmed black absorbs more long wave IR than white does (white things in the sun are cooler than black ones) You claimed differently. The issue I have is the things closer to the RHP get hotter than the floor does.


How do the objects closer to the panel stay cooler than objects farther? How?

How can you explain 8ºF difference in ambient air temps? Can you explain how that is possible inside an enclosure?

I'd suggest people use their heads and think! Nothing more than logic will bring most to the point of view I have.

Back peddling again? Do you own a Kane pad? I do. The smallest they make is too large for many enclosures. There are many many brands of UTH that are very good, Kane is one of the only brands that can safely be used inside an enclosure (waterproof and low wattage), very few need or choose to do so.

RHPs are not better than UTH they are basically the same. UTH are easier, to use cheaper to run and buy. There are less issues with them. I have never been able to get temps of 90ºF on the top of the highest part of the hide and 90ºF on the floor. Apparently I am odd in my belief that as you approach the RHP it gets warmer.

I have repeatedly said the same things.

RHP are Radiant heat sources (UTH also are radiant heat sources), they heat objects not air.

RHP heat from the panel down, things closest to the panel are hotter than farther things , this is not ideal for terrestrial animals it is for arboreal.

RHP ,on average, cost more to run and buy than UTH.

Probe placement is problematic. Snakes should NEVER come between a probe and heat source.

RHPs effect on objects changes based on absorption and mass.

The use of an RHP is best suited for arboreal set ups as it heats perfectly vertically. Terrestrial set ups are ideally suited for UTH unless the design of the enclosure is such that they may not be used (wood floors). They are a good second choice.

I have said the same thing over and over your arguments change constantly. The questions above you can try to answer i would like to hear a logical response please omit your digs and insults at me and just answer them. Anyone reading should be able to as well they are common sense.

I have not said you are a liar. I said it was likely your readings are not taken correctly. You may recall you told me you used an IR gun to measure air temps a while back? Clearly you cannot measure air temps with an IR gun? Do I need to find the quote? Please do not attack me I was careful not to make too many waves with you. You demonstrate the issue RHPs are poorly understood. I have used one form or another for going on 20 years I know what they can and can't do. Your claims do not follow the laws of physics.
