    Okay SO, this depends on if you can refill them with your water line continually or not. I’m assuming yes as otherwise someone’s answered a swap from a 40 gallon heater.

    They do about 12oz in a minute from a quick Google.

    Normal tankless water heater is about 3gal/minute. Which is about 400oz.

    So, 400/12 gives is 33.33, so since we probably want to make sure we hit at least that, I’d round up to 34. Would need a LOT more electricity for that, as noted by another poster below. Probably more than is actually run to most houses.

    Note: unsure how it’ll run without coffee in it, the flow is likely improved and thus you could possibly cut it down by quite a lot, especially with some modification to allow it to flow directly from the heating source in the keurigs you could definitely cut it down.

      A normal tankless is 3gal/min? That seems kinda low. Mine does 8 gal/min, but I did zero research. I just happened to move into a place that already had one.

        To be honest I’d check mine but I’m out of state right now, Google said normal is 2-5 so I figured 3 is probably fine for most “normal” houses, but idk. For me normal is really as long as I can run a hot shower and a dish washer at the same time.

        Checking online says mine is 1.8-4.3 depending on inlet temperature. Though I live in florida, so I likely get the higher end. Looked up average flow for one shower is like 2.2ish, so 4-5 might be more normal.

        Soooo, if you want say 2 showers, let’s call it 4.7

        Makes 626.1711/12, gives 52.2, so yeah again round up to be sure and we get 53 for a uh, family size house?
