I am looking to purchase an electric inline heater to my set up for those real dirty/greasy carpets that I run into that could use that extra heat. I use the rotovac 360i so I am on the water alot which i know will affect the heat. I am looking at the volcano 6000 as it can give an increase of 100 degrees in water temp instantly without letting off the water. My concern with this is tripping breakers with the heater, my portable, and rotovac. Its a lot of amps and I think it can be frustrating finding all separate circuits. Also, it can only be plugged into stove/dryer outlets from what I heard and this concerns me. I am also considering the mytee 2400 watt. I know that it wont heat the water as fast but I like how it has 4 switches and I think it will be more practical with the breakers. Just want to know some of your thoughts that use electric inline heaters and there experiences and recommendations. If there is a different model that you think would better fit my needs please feel free to tell me about it. Thanks Guys!
