This device cost the same as the proposed repair bill on my 10 year old Rinnai. I'd rather replace this every ten years than sink more money into a $1200 name-brand. Fingers crossed at 10+ years of service.
Looks good and installation was easy!

Don't buy this piece of crap
I bought this item to save space but its been a nightmare. This item has been a constant barrage of error codes. Once its reset its good for a couple of weeks and then it is back to being in error. When its in error, it makes a clicking and beeping every ten to 15 minutes. I have had multiple visits with both my plumber and my electrician and the problem continues to persist.
