Rinnai Rl75 - 5.0 Gpm At 60° F Rise - 0.82 Ef - Propane Tankless Water Heater - Direct Vent Review Feb 16, 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.
