What size RHP?

im almost done building my 6L3H2W cage for my BCI.
and i was wanting to heat it with a heat panal,
what size do you would you guys recomend?

my room temps are
75 summer
65 winter

i have already emailed proproducts
and had no responce

Bob at pro products is out of town for a show, should be back on monday! I would seriously wait on him, and give him a call. He's going to ask you for the dimensions of the cage, the ambient room temp, and the material used for the enclosure.... Then you might as well take a seat, because he will tell you everything you need to know about every heating element out there, and of course determine what size heat panel you will need. He is awesome, i wouldnt suggest any other rhp.
