Cautionary tale. After ten years of the wife turning the gas-powered hot water heater up to that notch just past VERY HOT (yep, ours goes to 11!) it finally crapped the bed in grand fashion. Much to my delight, because now we can get one of those tankless heaters. No more watching my wash temperatures bounce between 59f and 95f in a matter of seconds when someone wants to take a bath! Developed my first films today. Turned the hot and cold knobs, figuring it would warm up pretty quick, then adjust from there. Five minutes later, no warm water. Shut the cold off. Five more minutes, no warm water. Me very confused. I just used hot water half an hour ago in the kitchen. Go to the kitchen, and immediately there is hot water. Turns out that my darkroom tap doesn't draw water fast enough to activate the heater. So, here in the land of unintended consequences, in order to develop and wash films using my government subsidized green tankless water heater, I need a hot water tap turned on somewhere else in the house. Who'da thunk it? Anybody with an idea or resource for solving this problem that doesn't involve plumbers, I'd love to hear about it.
