Review on 🌡️ Zerostart 3308002 Series 8000 Light Duty Circulation Heater, 5/8" Inlet/Outlet , CSA Approved , 120V , 1000W by Chris Russell

Very disappointed. If you buy this heater and expect it to "circulate" coolant while heating up, like I did, you're as wrong as me. There is no circulation pump, the coolant itself does not circulate. It heats what's in the tank and that's it, I expect this block will soon burn out like the previous one. The cord is only about 12 inches long but I was expecting it as I see in the picture but when it says "Circulating Motor Heater" I really expected it to be circulating. :(
