What about money to replace a 10gal? You're using two other probed thermometers, why not just use the probe in the AccuRite? Or, why even buy the AccuRite if you're going to rip the probe off? Just buy one without a probe! TAPE I have the same misgivings about that Ralph Davis setup, and I have asked about it in the comments to that video and there was no response. Many others have done the same. He didn't even have a thermostat! My guess is he's unaware of the danger posed by the UTHs.
