You can put insulation around your tank and this will hold in some of the heat.

I can't answer your question as to whether you'll need another UTH or not. Every environment is different and so you'll need to get your tank up and running and then figure out what you need to tweak or add.

Remember though: UTH's do very little to raise ambient temps
i plan on gluing cardboard to the sides. it already has that cork background. also will be wrapping some foil around some cardboard and putting it on the screen leaving some space for air to circulate
