It's about 1 am on east coast and my husband is playing with our stupid tankless water heater. Our "old fashioned" regular water heater burst today. He decides that we will just use the tankless. I had about 10 seconds of hot water, enough to lather my hair and then freezing cold water. Never got hot again. He wants to replace the tankless that has never worked right with another tankless. I reminded him about when we installed that years ago, it never got hot water from the basement all the way up to the bathrooms on the top level.
What is your experience with a tankless water heater? Do they give you continuous hot water all the way upstairs from the basement, enough for showers? HELP ME PLEASE!! Thanks.

We have only had tankless hot water systems in the last four houses that we have owned.
Never any problems with them and hot water certainly got where it needed to be.

If you don't mind me asking, what kind of house do you have? Does the water have to travel very far to get all the way upstairs? We have the hot water heater in the basement and then two full flights of stairs to reach bedrooms. About 13 steps each.

We have a single story but the tankless heater and master bathroom are at opposite ends. Never a problem with hot water. DH did have them install the pipes with a recirculation system though. It helps when there are long distances between bath and water heater.

Our hot water doesn't have to go two stories but it does travel quite a ways to get to the kitchen. I've never had a problem with it going cold again after I've gotten the hot water. I love our tankless system.
I would find a good dealer and talk to them about your issues and see what they recommend. Is there a place you can install one closer to the bathroom?

We have a tankless in a ranch. It takes a moment or two for the longest distances to get hot, but once they do it doesn't go cold ever.

My daughter has a tankless and it had its quirks. If you called for too much cold water to adjust the temp, the hot water stopped coming. In order to keep the hot water coming to the shower I would run additional hot water to the sink so I was drawing a lot of hot water! If you can adjust the temp of the water coming out of the heater so you don't have to add so much cold, I think it works better. They have a very large home and once the hot water starts, it keeps coming regardless of the distance traveled. (They have two tanks for their house, one for the bathrooms and one for kitchen and laundry.)

It depends on how hot your water is coming from the tank and the brand, but mine has to get down to just a little more than a trickle before the water heater turns off. We do keep our temp at 120 degrees. There's no reason to heat it more than that because you aren't trying to make a tank last a long time. 120 is hot enough for everything we do around the house.

We have a noritz brand tankless that we put in when the house was built in 2004. Never had a problem with it. HOWEVER, since our house is plumbed on a circuit (water goes from water heater to washing machine on the opposite side of the wall, to master bath, to kitchen, to hall bath, to laundry room sink) it takes about 6 min of water running to get hot water to the laundry sink. To solve that problem we put a recirculating pump on it. Ours is a chili pepper brand. It's got a "red button" in the center of the house near the kitchen and we push that to get the water moving without turning on a tap. There is also a doorbell switch in the hall bathroom to turn it on from there. At the master bath, we just turn the tap on- hot water in about a minute since it's the second stop from the water heater.
Once it's hot, it stays hot forever. One time we were gone and one of the cats pushed against our tub faucet. It turned on and FILLED the 90 gallon tub. I have no idea how long it was on but the water coming out was still blazing hot. Our overflow worked and kept up with the fill thankfully because the tub was to the top!
My guess is that you have enough hot water it's just not making it to the second floor from the basement. Do you have a pump for the water to raise it? You didn't have this problem with the tank heater?

It doesn't sound like your tankless water heater is big enough for your house.

Thanks for your input. We decided on a good old fashioned regular water heater. Your stories verified what I thought. This only cost us $350 at The Depot. Husband is installing it right now.
