do you have a tankless?
No. Considered them when we built our new house in 2006. One supplier had a Rennai hooked up in his shop and sales office. We tried it out and found it really wanting. Everything in the house is propane except the water heater. My wife went to our electric co-op and bought the largest capacity heater they had, 85 gallon and never looked back. If I want to soak in the shower for a couple of hours, the hot water is there. Do the laundry, run dishwasher and shower at same time, hot water is there.
