Question about Heating & Cooling
The Rinnai relys on good water flow to fire it up. In saying that it runs out of water; thats actually not possible. The Rinnai just heats up water as it goes. Usually fault for installs on bore or well water is a problem with water flow. Causes are blockeed filters or you water pump from the bore starting to fail. I would expect you to have a large filter somewhere on the water line from the well. Try and find it and clean it our. The Rinnai also has a filter. It,s like a plastic round shaped nut just under the heater on the miidle connection. Turn the water off first, it should almost unscrew by hand, take it out and clean it (make sure you don't drop the O ring on it. Also some tapware has water filter right in the end of the spout, check these too. After you tried all this focus on the pump. Make sure no ther water id flowing, try the hot tap and see if it works. Do the same but slowly turn on a cold tap, slowly increasing the flow. Have someone out by the heater and see if the heater shuts down at any point. If it does it could be the water pump at fault. From what you have told me and am certain water flow is the culprit here. Really focus on anything that might lessen the flow before you start messing with the heater. Best of luck.
