Heating a 55 gallon enclosure

So what I found for a dimmer its basically like a thermostat, so can I just get another thermostat to hook up to my original Che? Also as far as my cool side goes will I just have to buy another che to keep that side at 80 degrees?

It is always better to go with a thermostat, especially a proportional one, than a dimmer. A dimmer is usually only for temporary use or as backup, much less control over temps than a thermostat has.
