What electric tankless water heater do you recommend to handle a home shower? From the questions I see here, the answers are mixed about whether it will handle an average shower or not.I'm trying to go green, and I only need hot water for two basic purposes, showers, about three a week, and washing dishes; the dishwasher I'm looking at (also on Amazon) heats its own water if the supplied water is too cold, even if it is straight cold).So I'm thinking for this little 1000 sq foot house with just myself, a tankless (electric) water heater would take care of my showers, while the dishwasher took care of its own hot water.Suggestions and advice will be appreciated.John What electric tankless water heater do you recommend to handle a home shower?

I think this will be too small for your purposes. I would look for something that has 4 gal per minute flow. Our is primarily used for a workroom in the garage.

you wont get hot water at full pressure with this unit, a shower I would not recommend, works fine in my out-shed where the tap water in winter is bitterly cold, this takes the bite out of the cold water, at half pressure you can get fairly warm water.

Depends on the heater but why? A tankless water heater only heats on demand so you don't waste eergy heating water that is not being used right away. You can possibly hook it up if you have an overflow output on the unit but you can really screw it up if you do the install wrong.

The unit should be more than enough for a two bath system. Electric consumption will depend on how long each personis in the shower. What you won't pay for is heating the water tank when no one is using water. Hope this helps.

I've had the same basic question for some time now. It's surprisingly hard to find out how much water a specific machine uses, but you could try researching that first. (Personally I had no luck.) One estimate that's out there is that a typical front loader uses 15 gallons of water. I figure slightly more than half of that is for the (cold) rinse, meaning in a worst case scenario (cotton whites) you would need about 7 gallons of hot water. That said, most water heaters start delivering cooler (i.e., warm) water as they approach their capacity. In other words if you have a 10 gallon tank the temperature might start dropping off significantly after using only 8 or 9 gallons of water. So you (I) might be better off with 10 or even a 20 gallon tank. My problem with all these small "point of use" tank type heaters is that they are low power, which means easy electric hookup but really long recovery times in terms of gallons per hour. My advice for someone building from scratch and wanting point of use for a laundry room, even with a slop sink, would be a small tank-less heater. You could use a 30 amp unit like the Bosch AE7.2, have limitless hot water with zero recovery time and about the same up front cost, though you would have to run however many feet 10/2 wire (relatively cheap) and add a 30 amp 2-pole breaker, also cheap if you have the room in your electrical panel. I wish someone made a high-power (30 AMP 220V) small-tank (10-gal or less) heater, but so far I haven't been able to find anything like that. That would be the best of both worlds, since experience has shown that small tankless heaters can be finicky, delivering bursts of cold water, needing to be reset occasionally, and are extremely sensitive to changes in water pressure, which is a big factor if you live in certain areas or are on a well like me.

It all depends on how far it has to travel to the shower. It takes a minute to get to my kitchen sink, because the heater is in my back room. For me, it takes no longer than the old propane tank I had before I got the tankless one.

That depends on the temperature of the water going into the heater. If it's hot outside it would probably produce warm enough water for a comfortable bath, but it can only do so much with very cold water going into it. I run two inline, and that is plenty for my shower (and my dogs) in the winter (10-30 degrees F). If you can afford it, two in line is the way to go for something like a shower. One is good for hand washing/doing dishes in my opinion, but not enough when it comes to the volume of water rinsing off dogs requires.

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.

The GL6 is not a tankless water heater, it is a small (under the sink) type 6 gallon water heater. It is okay for a vanity sink that runs at about 1/2 gal per minute, not so good for a shower that uses up water at the rate of 1.5 to 2 gpm. I have an apt. complex that I installed 5 Bosch Powerstar tankless water heaters 3.5 years ago. Nothing but trouble. In the last two weeks I have had to replace three of them. This time with Stiebel Eltrons (Tempra 20 and 20 +) and the tenants are much happier. Bosch no longer sells their parts. House Needs sells them with NO Refunds after purchase. That should tell you they don't even trust those tankless heaters by Bosch. Enough said.

If you don't use everything all at once. Mine runs one bath, kitchen and laundry, I have a small unit for second bath. One thing to check out first would be the electrical power required and it's availability. Requires three double 40 amp breakers and heavier gauge wire to carry the power. I took out a 40 gallon electric water heater and it has saved me about $60 a month so I would not go back. As energy prices get higher I save more. As with everything some common sense in using it should be observed, I love mine.

We have it in our 4 bedroom three bath house. We occasional take 2 showers at once or wash cloths while taking shower and have not notice problem with lack of hot water.The only draw back is it takes awhile for hot water to make it to kitchen sink etc. I would recommend for energy savings and the space saving aspect of it and you never run out of hot.

I would get one with ONLY cold water supply. That is all we have and we have enjoyed them wihout hot water. Unless you have a Hot water recircling pump in that bathroom, it will probably take too long to get the hot water there anyway. If you are very cold natured, I would get one with dual temps, and have it installed by an expert, or a plumber. You will probably still need the pump unless you are very close to your hot water tank. Enjoy!

Honestly mine is only used for maybe 20-25 minutes a day warming our Master bath, which runs colder than rest of house, while my wife takes a shower and dries off. I don't see any appreciable rise in electric bill in winter and my wife is very happy with how much it heats the room. It is a fairly large bathroom roughly 9 x 16' and seems to warm up pretty good. I doubt if I answered your question but we are pretty happy with ours.

I'm no expert, but my experience with the Suburban RV water heater is that it is so efficient I wouldn't bother with changing it out for a tankless. Issues with tankless water heaters would additionally affect that decision. I purchased and prepared to install a tankless in our Arizona home at 4100 ft elevation and upon reading the instructions found it wouldn't function well above 3000 ft without some modifications. My experiences travelling with RV's is that I frequently used my Suburban water heater at elevations as high as 8000 ft. without any issues. Also, varying water conditions could speed the clogging of the tubes in a tankless. Just my opinion..

Hello Kim,Thank you for your question. You've provided one key piece of information we need to answer the question, the incoming water temp. But we also need to know which hot water points of use that you might use at the same time, and the flow rates of each. Let's assume they are one shower at 1.5 GPM and one sink at 1 GPM. That's a total flow rate of 2.5 GPM. This heater provides a temp increase of 40F at 2.5 GPM. 45F + 40F = 85F. Therefore, the 10L is way too "small" of a tankless heater. We recommend the 16L which gives a 57F temp increase at 2.5 GPM. 45F + 57F = 102F which is slightly hot water for most people.Kind Regards,Ross GadgetsGo Hello Kim,Thank you for your question.

we've had atleast three people shower consecutively without running out of hot water... the propane just kicks on and keeps heating the water as it is used... so i would say atleast a 20 minute shower but who needs that long

I run two inline for my shower in Seattle and it works great. I don't believe one would do the job though, unless you lived somewhere very warm. One is more for providing heated tap water. Washing hands, brushing teeth etc, but not shower volume.

1-866-356-1992 to hear from Eccotemp directly. I received a reply directly from them in regards to your question and the answer is up to 100#'s. It's been over 2 months and I'm still on a 20# tank of propane used for BBQ's that's in the green. As I've stated, my bathroom is basically outdoors but protected from the elements. This is a very useful alternative to keeping down the electric bill!
