My suggestion is to have a very experienced high efficiency furnace plumber install the unit. From what I now know all aspects of the system need to be in balance to work properly. My unit is exceptional and my wife likes the colored pictures designating the various modes of operation.

Rinnai Rl94 - 5.5 Gpm At 60° F Rise - 0.82 Ef - Gas Tankless Water Heater - Outdoor Review Dec 15, 2016

I love this system. It's been installed in my house for almost two years now and have no problems at all and all the hot water I need. I would recommend this to anyone replacing a hot water unit. Originally, I had a tankless coil in the furnance and that required the furnace to run all year long. Now, I can shut off the furnace during the summer. Also, this product is energy star compliant which means a payback from uncle sam during tax time.

Away from home for the winter. Family checking our home found the problem, needed a new boiler. I was in another state, went online (this boiler was recommended by the professional), able to work well on your web site. Called a few times with questions, very helpful. Shipped out immediately. Boiler installed without any problems. I returned home a few weeks later to a warm home new boiler, and every thing working well.
