New "Back-Heat" rack not hot enough...

[el8ch]

You can use a space heater to boost your room temp.

I purchased a minature oil furnace (not so miniature, lol)... it is helping!

If it makes 88.5 degrees, that's really not too cold. What's the ambient air temperature inside the tubs?

Yeah, 88.5 isn't too bad. Ambient air temp in the back of the tub right now is at 86.5 towards the front it cools down to 80 and just below.

Insulate the rack.. I have a back heated hatchling rack and I covered the entire back with that flexible silver colored insulation sheets. Just cut it to fit and taped it all around the sides to help hold the heat in. Also, make sure the rack is sitting up off the cold floor. If it isn't on casters, get some 4x4's and lay them on the floor and put the rack on these. A layer of insulation around the sides will help greatly also. Really the temp it is at right now is good but any lower might be risky so you want to prevent any major drops.

Thanks! I am going to pick up more insulation and insulate the sides of the rack, back is insulated like you mentioned already. Yeah the temps are okay for now, it is just that I have everything working on "overdrive" to keep them there.

Love the rack though, man tubs are convenient and space saving..,
