We have been running for 2 years and have never had an instance where there was inadequate supply or water temperature. Our situation: Ranch Water heater in unheated garage 2 adults, 2 children (5yrs and 14yr olds) 2 showers run no problem simultaneously We have run the water temp anywhere from 104 to 120 with no problems. I can't speak for running at hotter temps. One option: to increase hot water flow, you can run at a higher temp, but then you will be mixing more cold water, so you need less hot water volume in your shower. I have done any math on this, but it sounds reasonable to me. We live in central NJ and have a 7.4GPM tankless natural gas Rheem hot water heater.

We have one that is supposed to be for our altitude of 7,200 feet and big enough to heat two applications, but it won't even fire enough to heat the water to warm let alone hot. The company has not been able to resolve the issue at this time, and we have replaced the computer chip twice the burner twice and I can not remember what else. This has been going on for two weeks now, going on three. I would like to have some hot water. Has anyone had issues with the Rheem tankless waterheater?

One tankless would serve to preheat the water, in order that the second one could further heat the water enough. This is an expensive option, and I am not sure what would be lost by the increased propane usage. A friend suggested stacking two tankless heaters together to improve the winter issue.

The first one was a Paloma, and it died when a little water remained in it after we had drained our pipes to go away and it froze. The second one is a Bosch/Aquastar. It puts out more hot water than the Paloma, but it doesn't work as well in the winter. This problem could be solved if we ran the pipes through the woodstove first. Tankless sytems work best if you can use a solar water heater to preheat the water before it goes to the tankless. This is one thing missing from our system, that we hope to upgrade soon. My partner hates the tankless and wants to change, but I won't let him. Also, they make more expensive models that can meet higher demands. We can't shower and wash dishes at the same time. Our Aquastar is the biggest source of propane use we have in our home. We are on our second tankless heater in 15 years.
