Keep getting "fill" message
Installed this about a year ago. Heats the home very well. Is very quiet and compact, clearly innovative product.
Unfortunately, the first six months, while using dhw, the water would turn ice cold because the system would go to 'fill' mode. I needed a new (bi or tri) valve which worked well after installation of the new valve. Now after another 6 months, the same thing is happening again. Not a great surprise when your taking a hot shower and the water turns ice cold.

Mixed Feelings
Mixed feelings . Heats well. However my understanding that it had recirculation pump built in like Navien.
Save on gas but for dhw bit slow to deliver. Once it gets hot its good.

nothing but trouble.no one will work on these
works great sometimes. Other times looses pressure on the water heating and turns cold. Tried several listed Rheem companies and no one will work on it. Yes it might work fine, but if you have trouble with it you have to buy something else. 6 months old nothing but trouble

Works like a charm. Quieter than the 1st one I bought. I bought this one as a replacement after the original broke within 6 months of use not using the in flooring heating option just DHW. I think it was just a lemon but hoping the new one holds up. Either Rheem and Home Depot handled full reimbursement and replacement of the unit including removal and installation of the new one. Happy for now.
