Our water is very hard. I have read this is a big concern, especially with tankless hot water heaters?

They aren't saying it makes water harder, they are saying the effects of hardwater on water heater is the issue. Not the water heater causing hard water.I don't think you need to worry about hard water. Hard water causes scale on inside of water coils in which acts like a insulator and reduces efficiency over time. This is a concern for all types of water heaters.A simple solution is to get a water softening system if you need one.

Our water is soft, so I can't say from direct experience ... but I have read, and it makes sense, that hard water will clog the small passages in the heat exchanger. You could flush periodically, but that would be a hassle -- or soften your hot water. Seems like maybe a tank heater's the way to go for you.

It shouldn't be a problem, as long as you flush the water heater with vinegar once a year. This is regular maintenance regardless of how hard the water is. You can find a decent circulation pump for around $50 on Amazon, and tutorials on how to do this on YouTube. Hard water shouldn't stop you from buying this heater...has been working flawlessly for us for more than two years!

We have found that this helps with scale deposits build up, but not solution for appliances, we are in the process of purchasing a soft water conditioner as well to aid in removal of all scale. We bought a Tank-less Walter Heater' Tempra Plus by: Stiebl Eltron for the house instead of your standard water heater that corrodes over time. This water filter aids in the removal of scale entering the home it does not however removed all of it, although we have seen a significant improvement overall. We figure with a water softener to aid our tankless system will do the trick. :O) Our tankless system with this filter is one of the best things we have done for our family and home.

I guess I cannot help you there, we are in the country, however are served by a rural water system. The water comes from the river and is treated a lot. Well water is typically hard. you may have to change the filter more often. Hope I helped.

I have not had a problem wth the float. T tank and that valve is where I have had trouble. I will have the unit shut down with a full tank of water. Hope this helps.

Too many unknowns to answer directly, could be anything from valve not opened fully to sediment knocked loos and lodging in your faucets. The unit itself should not appreciably affect water pressure; in spite of differences in heating mechanism, it is still just a water-in-water-out canister.

After you clean it, start using filtered water and this will end your hard water problem. I buy gallon jugs of filtered water and haven't had the problem since I started doing this.

hard water will clog up the coil inside the heater you should get a water softener it wont work if the power goes out

I don't know about the hard water issue. I had to return the filter that I purchased. I could not stop the unit from leaking around the top. VERY disappointed.

I wonder if you maybe have a lot of minerals in your water and if they're possibly collecting and interfering with water flow... Having a plumber check it out would probably cost nearly as much as a new one so I don't know if that would be an effective way to proceed or not. If it's something focused on the faucet, maybe you can replace just that piece instead of the entire heater unit. I would start as L. Willman suggested and contact Waste King to ask them for assistance.

On the winter mode setting and low flow setting the water is extremely hot. Our unit only ran for a short time, however. I'm not sure what failed, perhaps I needed a pre-filter? A downside is that I would have to send the unit to South America for servicing.

I use tap water which is hard water and not distilled water. Had no problems so far. But I don't use the humidifier frequently. Might probably want to clean with vinegar if prolonged use results in sediments or residue.

It is hard to say why it no longer lasts as long. I have not had that issue even with new filters. It could be something has gotten worse from your water source. Maybe your hot water heater is releasing debris. That is my best guess. Sorry I can't help further.

I do not have a hard water problem here, but having loved in Arizona previously, from Experience with hard water there, I would not use this unit unless I had a water softener system installed and functioning prior to installation.

More important than how big your home is would be how close is the tankless heater to your point of use and how cold is the incoming water? I live in Florida, so the water is never very cold which helps the heater to work very well for me. If your incoming water is colder than 55*F, I would recommend a bigger unit than the N120.

That sound sort of dangerous...i looked it up on the insinkerator doctor and it wasn't really a "question" though it did say that over hot water could lead to spitting and spouting of water. Perhaps turn it down a little and call insinkerator if that doesn't work.

No, Not necessarily. Unless your home is on a well water service. For the most part all tankless water heaters are designed to be maintenance free.

The hot water is not a problem. A rough tumble and drying in a dryer is where the liner can be damaged. Use delicate cycle and hot/ hot and you should be fine. Then dry on low or no heat.
