How many keurigs would I need to daisy chain together to replace a water heater in an average house?
How many keurigs would I need to daisy chain together to replace a water heater in an average house?
Not as many as you think, a water heater only has 3 times the electrical capacity of a standard wall outlet. So probably less than 6-10 Keurigs, but you'd need them on 4-5 (or more) separate circuits otherwise you'd blow the breakers.
48If we're looking into their heating capacity they should be able to heat approximately 7 and 1/2 gallons of water an hour. A lower end water heater can supply about 85 gallons of water per hour so you'd need about 11 of them to meet a small house capacity.
If we're looking at their water holding capacity and power consumption. The average house has a 40-60 gallon water heater and a Keurig has a 48oz reservoir. You would need 107 to get to a 40 gallons capacity. When heating they use 1500 watts according to the Internet, so you'd need 160,500 watts (or 1,345.75 amps) of Keurigs to be the equivalent of a low end water heater for a house. The average 40 gallon heater uses between 4500 and 5500 watts.

You say between 6 and 10, the other commenter said 427. I don't know what to think!

Oddly specific question
20Okay 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.
2A 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.
1To 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?

You should factor in battery backups for each coffee maker.
