In 2006 I purchased a duplex (built in 1996) in which each unit has an Apollo Hydroheating system. In my unit I replaced the hot water tank with a Rinnai tankless and have had no problems until recently. I just replaced the upstairs hwh with a Rinnai after it gave way, and my tenants are thrilled with the performance. They no longer have to turn the heat off in order to take a shower. I never have had to with mine. Jim Katen, you are amazing with all your help! Especially the Manual, which will be invaluable since the HVAC people in the area don't seem very familiar with the system. Unfortunately my printer gave out halfway through but I have the link saved. I'll post again when I figure out my current problem - or explain it and see what people have to say.
