Heating a breeding room. Help on Heating methods.

[timothyng1998]

So, I've already got a decent sized collection, and it's still growing. My passion is lucky enough to reach the school, the school will be investing $8k on live reptiles and fish display!
I need to increase my woodies breeding scale, so far i've got 3 tubs and heat mats underneath each of them.
I'm thinking of going big, having 15 tubs, across a wall in a shed/ workshop.
The shed was used as a drum room, so it is well insulated and has an aircon installed.
The question is: What is the best heating method to heat the whole room to around 30 degrees?
I got a 400w wall mounting heat panel to raise the whole room temperature.
What methods are you people using to heat rodent rooms/ insect rooms/ reptile sheds?
Thanks.

I use an oil filled "bunnings" $59 heater with built in thermostat and timer, with an osolating fan blowing across it. It kept the 3.6 x 3.6 x 2.4m coolroom heated to 30C when outside was 10C no worries. There was about 2 degrees variation from bottom to top (2.4meters)

How many watts is the heater?

500watts with 50mm walls on the coolroom. Its normally off when i go in, but i really dont know how long it runs.
