Unpleasant surprise this spring the cabin water heater stopped heating at all. Goggling says the upper thermostat controls both and is a common failure. So yesterday I ran up there with one and still don't really have hot water. If you hold your hand under the hot and then the cold you can feel a little difference but it's still far from even warm. Unfortunately I didn't think to grab a thermometer. Buddy that was with managed to get a really ancient volt meter going and we confirmed power at the top thermostat and element. Nothing to the bottom which according to one article we found is expected. So time for new elements? Hoping to get this right as it's 120miles to the cabin and once their the closest good sized hardware store is 50miles.
