How does it work? Can it fill a large bathtub without running out of hot water?

depends on size of tub, but, 40 gals is more than enough as it is mixed with cold for a normal bath tub

I haven't actually tried it, we bought it to bathe our toddler in a place where we don't have a bath tub. I would guess it can as it is very thick walled. I can't imagine that hot water would have any effect on it.

First off, I must say, we rarely EVER run out of hot water. We have a very large, jetted bath tub that we can fill and still take two showers simultaneously. I would say the one or two times we have run out of hot water, it has been less than 20 minutes before we have more. We have ours set to the lowest temperature setting because we have young children and don't want to worry about the water being hot enough to scald, so that might have something to do it. We absolutely love this hot water heater!!

We use it hooked up to a garden hose for showers outdoors. We have never run out of hot water.

There's a water reservoir that you fill up before bathing them. It doesn't connect to the bathtub. And the power source for the spa is batteries. Hope this helps :) lol

it could be battery operated, if you attached a 12v battery to it. Although it will, technically, empty a hot tub,it really won't do it in anything resembling a reasonable amount of time. This is more of a small fountain or waterfall type of flow.

I hooked my shower head to it at first so it's a smaller connection but at home Depot I got the fitting to attach garden hose. It is a wonderful and economical water heater. It fills my tub no problem... Even our blow up swimming pool. The wind will blow out flame if not protected has been the only outdoor concern... Easily fixed... I would recommend this one above the smaller option that already takes garden hose fitting because it can not pump out incredibly hot water consistently. This one does with ease.

There are too many variables to really answer that accurately. How often and how long are your showers? Bath tub or just showers? Do you have a dishwasher? What temperature setting will you have on it? How long is the hot water pipe run to your furthest appliance, etc. I have a large tank with generator, fireplace and the hot water heater. I fill it up once per year unless the generator runs due to a power outage. The Rinnai is quite efficient, but I would recommend you go with at least a 30lb tank and have another full tank on stand by until you learn your usage.

Tankless water heaters will handle almost anything, but the trick is sequencing / timing. If all three teenagers are going to take baths or showers at one time, it may not provide enough hot water. To some extent this will depend on the size and length of your water lines. I bought one of the to heat my hot tub and two larger, 9.5 gpm units; one for domestic hot water and the other for radiant floor heat. They all work great. The price does seem to vary so keep an eye on the prices over time. The PVC vent system is much better and extremely lower in cost than those tankless water heaters that require stainless steel vent pipes. Good luck.

I am not sure I understand the question. My daughter has the tub hanging from her shower curtain rod. When they want to use it, they open it up and place it in the shower stall and then turn on the water and it fills up with warm water from the shower nozzle. Is that what you are asking?

I don't have any first hand experience but for the small price it would appear to worth trying. It has worked great on my bath tub where it obviously is subjected to hot water.

No, does not produce enough pressure, mainly a volume pump. Works very well for water tubs, tow behind tubs, swimming pool bladders.

Yes - if you first spray the tub with scrubbing bubbles and let it sit - it works well. Don't fight the way the head moves and your tub will sparkle in no time. It's a great back saver.

Thank you for the question. I've never run out of hot water. The unit is in the bathroom of our woodshop. Two gallons of hot water is quite a bit to use at one time for me. I'm assuming that the unit would probably have to re-heat after it runs out. Other than that, I cannot say enough good about this little heater. It is wonderful for the application that I use it for.

I've only used it once or twice in the heat of the summer, and it took all morning and afternoon to heat the water to about 100 degrees. I doubt it would work satisfactorily in the winter. My advice would be to invest in a camp stove, the more Btu/hr the better, and heat your bath water that way, or learn to enjoy being grungy and stinky.

I don't have a spa tub but I think the unit will work well for you. We have guest and friends who visit and do tub baths and they run a lot of water and the unit keeps right up and where we live, we only have propane. The unit works great and gives you a lot more room and probably saves some money on utility cost.

You will need to get an 'on demand' heater and some plumbing. I have used mine hundreds of times and it still works, but it was not meant for more than 5-10 gallons, and a severe hazard sticking this in your tub anyway.
