Tankless water heater for a IBA Razor

[brewer40312]

Im looking for a Tankless water heater for my IBA Razor. I had a RINNNAI RCU98i in the past. It lasted about 5 years, I was using it for my SS bays.
It was a 11GPM and 199k BTU heater. attached is a picture of my old one. If anyone has anything that they feel is better built please let me know.

Are you running soft water through the one for the SS bays? That seems like a pretty short life span.

It was hooked up to the soap tank ..

yes it was for the self serve bays. There want a filter on the heater and i feel like that could have had something to do with it.

Do you have over 50 psi water pressure to the water heater at all times? IIRC that brand needs that or may not operate correctly. Its possible that played into the short life. The Takagi units only need 15 psi to operate and those are the ones we went with.

They are new to us but many on here have used them for years with really good luck.

I do not have a softener for my self serve bays. That could be the issue

Have you checked your water for hardness?

I use the takagi ones at my house and the water is pretty hard. They last about ten years. One runs the house potable water the other runs the radiant floor hear. I buy them at supply house dot com

I have several Rheem in service since 2010. Takagi also, but 1 of those failed in 4 years. Leaking primary heat exchanger but covered under warranty. All for the most part dependable units.

I run all Navien at my locations. Really good heaters and they have residential and commercial use warranty.
