Sump melted by heater?
>Hello to all at WWM: >>Good morning, Marina here. >This might sound like a silly question but here goes. I currently have two 200w Visi-therm heaters in my sump. I have always been concerned if the suction cups did not hold and the heater actually was laying directly on the acrylic can it in fact melt the sump? Always wondered……never asked until now. Thanks a million, Gene >>If the sump is acrylic, and the heater were to become stuck in the ‘on’ position, yes, it could happen. Is it *likely* to happen? Not very likely at all. But, if really concerned, then you could simply slip them into a sleeve of PVC, with many holes/notches cut into it, they won’t usually be sufficiently hot to melt PVC. I would like to suggest spacing the heaters, though, to help reduce temperature differentials. I like having one hidden in the tank, and one remotely located (the sump).
