Couldn't you use that as a large display of tank temperature? No more tiny thermometer. Visible across the room. You would just have to epoxy it into a T fitting on some PVC
somewhere in the flow of the tank. Probably the return. I know it wouldn't work like a heater controller, but I want to get some WonPro Titanium Heaters. If I go w/ Pro Heat I, I'll have reliable heaters, and I can get the temp probe from Radioshack. Does it have an alarm (even if it's just a beep) if it goes above/below a certain temp? What do you all think, and what exactly was this called at Radioshack? And how much was it, I think I missed that part. Thanks!
 Oh, and yeah, I live in MI, and it's been dropping below 0, with average high in the teens. What's a safe and effective way to combine hot/cold water to go into the RO
unit? It barely trickles, and I'm assuming it's because the water is darn chilly. Thanks. [/edit]
