I pretty much dislike ours, yes you don't run out of hot water so for multiple people showering etc it works good.
I hate that you have to run water for a quite a while before hot water finally comes out, if you turn off the tap for a minute or 2 repeat that process. So you either leave the tap running (while doing dishes for example) or continually wait for hot water to come back. I especially find while shaving there are times it takes forever (a few minutes) for hot water to come back, I assume this has something to do with a rest period for the unit?
This makes me question how much hot water is actually getting into things like the dishwasher and wash machine which don't draw for very long and also if it's much better to be wasting all this water waiting for hot to come out of the tap vs the natural gas savings.
Maybe our builder just put in an inferior brand or something but that's my experience.
