Herpstat thermo questions

Hi, Just got my Herpstat from Matt at MG, great thermostat! I was just wondering, if there was a safe way to add more heating devices than the 3 outlets they give you on the thermostat. I know not to go over the wattage, but I would like to put more than 3 heat mats on it. Any suggestions/ advice sure would be appreciated!

As long as all the setups are identical(as they have to be or you'll get wonky temps), you can just plug a power strip into one of the outlets on the herpstat and have a few more available.
