How many simultaneous showers will this handle (in the winter, in a northern state)?

9.5 gpm, each shower will be about 2.5 gpm, so it can easily handle 3, if all they ran was hot water and you have a typical rise of ~60-70°, and it would still have enough left to run a faucet or dishwasher. But since most people will run a mix of hot and cold, it will be able to handle more in practice (probably about 4 simultaneous showers). As long as your water pressure is good enough.

I live in the south, but we have had a rather sever winter. My best guess would be that it would handle four without problem. I filled a 800 gallon hot tub and had to wait for the water to cool to get in this winter (120 f) is a bit hot for me. It is a very good unit, but i would extend the exhaust further from the clean air intake than is recommended. I put an elbow and a 36" piece of pvc at a 90 degree angle from the clean air intake. No error codes no matter how much water goes through after that change.

I have had my Navien tankless going on 3 years. It will support 3 shower at once without breaking a sweat. Most problems with tankless heaters are related to the installation. I had to upgrade my gas meter to handle the additional gas flow.(the gas company did this for free) The only drawback I have encountered is children will take a 2 hour shower if not monitored, running out of hot water limited this in the past.

Yes, it will supply 2 showers simultaneously, but depending on the temperature, it may reduce the flow rate to each shower. And it will absolutely fill a Jacuzzi with hot water. That's the beauty of a tankless hot water heater - you never run out of hot water.

My water heater receives a cold water supply of about 40 degrees, than produces HOT water @ about 140, depending on the distance between the heater and the shower (travel time) you should do fine.

North Texas? I'm not sure how that would impact anything? When we run two showers at the same time, you definitely feel the difference. It's possible, if you have low-flow showers. We like to run them full blast, so we generally avoid two at once. And 'yes' it would fill your hot tub (it creates hot water for an eternity). The only caveat is that it will take a while. I've owned this heater for (4) years now and still think it's great.

Don't know - it is installed at my barn in S.Fla. on an outside wall, and I have not had to use in winter yet. But I cannot imagine why there would be any problems. I suppose if the weather is at a freezing temp the pipe and shower head could freeze up; but other than that I do not know. Seems like a heavy duty fixture.

Can't speak to the multi-shower thing, but I can offer this: Shower running, dishwasher going, washing machine churning, sink on...no drop in hot water in the shower. All this in the "dead of winter" in Wisconsin. Hope that helps.

That's a lot of water...not sure, it might burn out the element before the water got hot, but probably would keep it from freezing. Maybe having 2-3 would work. Would a hot water heater work better for your needs? Sorry

I've used this unit for the entire house for the past year. No problem so far. My clothes washer is not as warm using the warm water setting. For showers and other manually controlled water temperature items, the unit works fine. I live in South Carolina. I would not recommend unit if you live in Alaska.

Since you are in CA, it probably would be fine unless it gets really cold in the winter. That said, since you have 2 60 amp breakers already installed to the location, why not be safe and use a bigger Stiebel Eltron (SE) that specifies 2 60 amp breakers. You can use less than your breakers can handle but never more. Without going to the trouble of looking up the various SEs, I think you would be better off with a SE tempra 28+ (+ if they make that version) IMHO.

Yes. Our Rinnai is mounted on the exterior wall and the water is heated as it comes through the pipes into the house. The hot water is available throughout the house. Whether you can have two showers going at the same time is more a question of water pressure.

One of these has supplied my entire house for a couple years now. Works fine. Will say two caveats - one: we rarely use two showers at the same time. two: unit needs to be central to the points of usage as the heater begins to heat the water as soon as it starts to flow. If the point of use is far from the unit there will be a delay in obtaining hot water. The longer the distance the more the delay. This can be a concern as water waste is an issue. The best part is once you get hot water is just keeps coming...and coming

Sorry for the delays answering ur question. I have both & both models are great. Having dual system warm & cold water is great in winter :-)

Yes, it's more than enough. When we lost power this past winter, I had this running my furnace, well pump, hot water heater as well as the bathroom lights so we could take showers. The only thing this could not run was our electric range. Everything else worked well with this model.

this unit is very small, i live in the central valley of california. not very cold here, but the ground water temp. is not very cold, and the unit barely warmed the water for one shower. the answer to your question depends on where you live, but i would say "no".

this unit needs to be installed inside and out of freezing weather conditions .

Not sure but should handle two. If you don't have the water on full blast it should be fine, you can also turn the temp up if required. Need to conserve water here so I take army style shower, get wet soap up rinse off even better with a friend. Good for the planet.
