THE INSTALLER GAVE US GOOD ADVICE. WE ARE USING THIS IN A SECOND HOME AND IT WAS TOTALLY WASTEFUL TO HEAT UP A TANK OF WATER EVERY TIME WE USED THIS HOMW.

It's great it takes a while to get useto multi tasking. Not waiting for the water to get hot.

Advanced plumbing From Barre MA worked with osterman to install both compaanies were very helpful,reliable and prompt. Work done was excellent and we are very satisfied.

Only problem I have is that you have to run the water a couple of minutes before the hot water comes out.

I ordered the product online because the 1st installer I contacted quoted a very high price. The installer ordered the parts, however.

Rocky Mtn. Air Solutions delivered ontime, as promised & very professional.

We haven't hooked it up yet, but I can't wait until we start using it. We had to hook up the gas first.

We had a small issue concerning the placement of the Rinnai vent in relation to the dryer vent.

Since I wanted a Rinnai system to reduce my electricity costs, I would recommend that Rinnai reach out to potential new customers with information on how purchasing a Rinnai system saves people money
