Rinnai Rl94 - 5.5 Gpm At 60° F Rise - 0.82 Ef - Gas Tankless Water Heater - Direct Vent Review Dec 12, 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.

Quality Jul 07, 2016

Have used Runtal UF series before and the quality is excellent. Now if they could sneak more BTUs per foot.

Good Unit, No Problems Jul 23, 2016

Used this unit with a 12, 18, 9, 9 set up with a 4-way distribution box, it has worked very well with very little noise. There is a very high pitched sound you can hear if you are near it, but it is not very noticeable.

Great Install Apr 15, 2016

My brother and myself installed the boiler in one day. I'm a licensed plumber steamfitter and the install was very e-z. Even for a DIY it's a very easy install.
