Are these worth the installation cost? Buying our retirement home, and it has a water heater (75 gallon) in the attic.Second floor heated by an AquaTherm system. Don't really like that idea, whole bunch of water that could escape.. Running on propane. Plenty of room in the laundry room, gas and water piping present. Only issue would be the vent, might have to go up through the ceiling into the second floor attic then to the roof. I suppose it could be mounted in the same spot in the attic as well. In AR, so temps are moderate for the most part. Well water, no idea of its temp right now. Going to replace the older HVAC systems (two split units) so don't need the 75 gallon tanked one anymore.
Tankless water heaters have a huge burner in them. You need to have a flu study done to see if your furnace will draft with the tankless running. Tankless water heaters don't do well on well water, pun intended.
