Foil under UTH question

Hi, I'm struggling to find a clear answer for this on google.


Is it okay to place foil under my UTH to help reflect more heat to the tank, or is this a ventilation issue?



I'm going to be upgrading my BP to a larger tank and being in Canada, I'm trying to conserve as much heat as possible.

I'll be using a heat lamp(dial controlled) as well as my UTH with a thermostat.

Already planning to buy 1/2 in thick foam insulation board to cover 3 sides + most of the top. Any other suggestions are absolutely welcome!

I'd wouldn't use foil, not because it would cause a ventilation issue, but because of my concern that it may short out my heat mat and cause a fire.

I agree. :gj: Installation instructions that I've always gone by say do not install on metal (& I've been using Flexwatt UTH literally for decades- safely with no issues). Most of these UTH products (Flexwatt & similar knock-offs) are not heavily insulated- it wouldn't take much (like the plastic being abraded & left unnoticed) to be a safety issue when used on metal. I'd say don't do it. ;)

As far as "ventilation", Flexwatt instructs users to leave a few gaps- that helps to guard against overheating when used on high. I've ALWAYS done that too. ;)

What I'd suggest- rather than putting foil under it, is to put ceramic tiles under it- as they absorb & help retain heat like rocks do. My installations are on wood furniture, & the ceramic tiles help protect the wood also, but if you lose power, tile helps to hold the heat- whereas foil conducts it without preserving it.

Sorry for the late reply!

Thanks very much for the answers and advice! Ceramic tiles sounds like a fantastic idea, I'll definitely pick some of those up! Appreciate the help :)
