    Best tankless water heater

    I'm looking for a tankless natural gas water heater for our 3bbl brewhouse. Any recommendations on brands and models? What GPM flow are you getting with yours and at what temperatures?

    We use 3 Rinnai C199s. Taking our castback water at ~160F to 185F, we get 5.8-6 gpm throughput. Bringing tap water @ ~45F to 185, we get 2.5 gpm.

    If your water is much harder than rainwater, expect to clean the heater frequently and plumb it with that in mind. I'm cleaning ours every two weeks, and the filters daily.
