zoo med UTH questions

I have noticed even when I set my thermostat as high as 15 degrees my zoo med heater only gets the temp on the ground in my bp's hot side 89 degrees. I just looked up the zoo med uth and it says is only gets the uth 20 degrees over the room temperature. Has anyone else experienced this?

No, I keep my house at about 68* and before I got my dimmer and temp gun for the zoo med UTH the bottom of the tank under the substrate was over 130*.....what kind of substrate are you using? How are you measuring the temps?

If you have an ultratherm UTH then I can see, but all of the zoo-med ones I ever checked would go up to 130ish which is obviously too hot.

Just a regular one.My house has been at about 65.I use a tempgun to chec my temps. It is a laser pointer. TG1 . I have a thic sustrate of coco shavings(?) and ecoearth.Alot ofsnaeeepers use this to keep humidity up where we live. It is pretty cold here at night still in the 30's low 40's I live on the water so it stays cooler.

I feel with my hand right on it and it is not burning. I am running each outh with a hydrofarm. I m looing into herpstat but they are sold out.

Okay are you measuring under the substrate too? because 89 above the substrate is fine, but I bet it is much much hotter on the bare bottom.

No I am checking under also. I raised the temp in the room to see if that helps. I lowering them lately. I am going to see if it is warmer in the room I will chec every 15 minutes see if it helps.

I have one hydrotherm set at 99 it is now 90 under the substrate.I have the other at 99 and the top of the substrate is 90 does that seem more accurate?

How accurate is your temp gun?

I don' tknow it is brand new. It just says tempgun TG1.Seems good I am always checking the temperature of things around the house it's like a new toy.:D
