If you get the Little Giant, get the High Pressure or HP model so you can do tile and grout. I had a #3 but Les Judson suggest you run a #4 Little Giant for unlimited heat. I would run out of heat when doing T&G with my #3 LG.This is good advice. Thank you. I'm really excited and very humbled. I've been looking into the little giant heater system for a while and now have a great excuse to pull the trigger. Awesome.
