My hot water heater is just about to go out I'm going to have to replace it. In doing my research, I've been seeing the tankless water heater. It sounds like a GREAT idea; but being from the old school, I can't really wrap my mind around it. I understand the concept, but not sure that I trust it. So, therefore my question...if you've had a tankless water heater, what was it s strong points & most of all what was its weakest points...or more to the point, what did you think of it???

I don't have one but I had to write a couple articles on tankless water heaters and they are very convenient. However, they are also very expensive and it takes up to 10 years to recover your investment through the savings you'll get on your gas or electric compared to what you now have. They are great for families who have a great demand for hot water because you're never out of hot water. But if you're just one person without a lot of demand for heated water it would be more economical to get a standard water heater. You also should check to see if it's compatible with your house. I spoke to a guy when I took my car in for service and he had wanted to install a tankless water heater--it turned out he lived in a house built in the 70s and would have to have an expensive re-wiring job in order to scommodate a tankless water heater.

Responses like this is EXACTLY why I ask here first!!! I live by myself & my house was built in the 60's. The ones I looked at were just about the same price as the tank heaters I looked at so that tells me they are NOT going to work very well!!! Since I'm going through a time where everything is wearing out at the same time, I don't have any spare money just laying around!!! My refrigerator, washer & dryer have gone out recently too. I'm now buying in order of importance...water heater comes first as I just cannot take cold showers!!!

3honor, a lot of older houses here were built by the ones who first occupied them and our building codes weren't real stringent until the past 50 years or so, or so people told me at a construction company I worked at a few years ago. So it's very possible that newer inventions might be too much for the wiring in some houses.

LadyMarissa, I know just what you mean! My furnace broke and I had to replace it in December--shortly before I found out I'll be moving! Thank goodness all the other things aren't dying on me but it will only be a matter of time. I'm going to be a renter for the next few years after I sell the house and try to sock away some serious savings.

We use a tankless water heater and I love it. You NEVER run out of hot water. Well, I suppose you could if you run out of water or whatever energy you're using to run the water heater (i.e., electricity, gas, etc.) but as long as you have water and energy, you'll always have hot water, no matter how much is used. My husband takes a shower that lasts around 20 to 30 minutes every morning. Before we had the tankless water heater installed, I had to wait to take my bath. (He ran the water until it began to get cold.) That is not an issue with the tankless water heater. I always thought it was such a waste to be heating and reheating water stored in the water tank when it wasn't being used. That's why we installed the tankless water heater. Besides that, living out in the boonies and using a well, there is something in the center of the water tanks that can become corroded from hard minerals in the water and make the water stink. You don't have that issue with a tankless water heater. Weak point? I'd say, at least for us, running out of propane. We don't have natural gas coming into the house, just electricity, so we have a propane tank just for the tankless water heater. So far we've been able to avoid running out of propane except for two times when we first had this installed and didn't know how to gauge how often to get more propane. Overall, I love it!

GREAT news!!! My house is run by natural gas & I've NEVER had an occasion where I didn't have gas!!! I'm much like your husband...I do LOVE a good, long HOT shower...20 minutes is short for mine!!! My current heater frequently runs out just after I lather up with shampoo & I have NO other option but to finish with cold water. I can adapt to a lot of things, but cold showers is NOT one of them!!! Plus finishing with cold water loses the good effects of the initial hot shower!!! I need to do a LOT more thinking & research before making up my mind. Sadly, I think my current water heater is going to push this process up to an emergency level real soon!!! Thank you for letting me know how well yours is working as I was mostly concerned with the reliability or pitfalls of the unit!!!

I don't know what the warranty is on these things but we've had ours for almost five years now and it has never disappointed. I'd have to say that they are very reliable. Oh, one thing. Gas is apparently the preferred energy for these things, at least the ones sold in this country. My husband was asking about which would be better, gas-run or electricity-run and everyone he spoke to said the gas-run ones are best. One employee at Lowes told him that they had several electric ones exchanged for gas. I can't remember the reason but apparently the gas-powered tankless water heaters run much better (AND cheaper). That's why we got the propane tank installed. You're already ahead of the game by having natural gas. I wish we had natural gas instead of electricity. I'll make sure to pick my next house more carefully.

Gas is most definitely MY preferred resource!!! I prefer cooking with gas as I have complete control over the amount of heat used or not used!!! Gas heat is a million times more comfortable than electric heat!!! When I moved back down South & was looking to buy a house, I chose this one mainly because of the gas connections. Oh yes...it is a million times CHEAPER also!!! My parents changed over from electric to gas because my utility bill was 2/3 cheaper than theirs every month & our houses were about the same size. My Mom stayed cold when they had electric heat & bragged as to how warm she stayed once they switched over to gas!!!

We had three when we lived in Singapore, but that was quite a few years ago. There were separate heaters for each of two bedrooms and one for the kitchen. I liked them, but the biggest drawback was that the water had to be turned up to a certain force for the heater to come on. It was instant at that point, though and you can't run out of hot water. I found out later that the point the heater kicks on can be adjusted. Now, they make them big enough to use in large buildings, so you can get one for your entire house. They're more expensive to buy than tank heaters, but a lot less expensive to operate. If I ever have to replace another water heater, I am going to get a tankless heater. (IF I can afford it at the time!)

Surely they have corrected the pressure problem by now!!! If not, that shouldn't be a problem as I like full pressure & high heat. The prices I'ver seen online are not that high; however, I'm sure the installation will increase that price significantly. I love the idea of instant hot water!!! A good portion of my water bill is waiting for the water to get hot before showering or washing dishes!!! My house is not huge & I live alone; so I'm thinking one tank should cover my needs. I can't wash dishes & take a shower at the same time!!!

I was first unsure what you meant here until I have read the others' responses. So now that I think I know what you mean, all I can say is that I never tried having a tank water heater, just the one that automatically heats water whenever needed using electricity. As the rest have already said, it's really efficient but the problem would be if there's power outage.

Oh men! Now I miss having such luxury. I wonder when I could afford to buy one of those electrical water heater. Anyway, nice to hear you finally know what you want. Good luck!

I think I have the power outage problem covered as I would be installing a gas heater. I've lived here for 14 years & never run out of gas!!!. I love the idea of instasnt hot water & NEVER running out of hot water!!!

Yes, it is a luxury & one that I've ALWAYS appreciated!!! There is NOTHING more heavenly than a good HOT shower first thing in the morning!!!

I thnk that is what we call an Electric water heater LadyM. It heats when you turn on the tap anbd stops when you shut it off. The main problem is that if you have power outtages then not only do you lose your electricity but you lose you hot water too. With a tank you may well have sufficient to get you through the outtage. However, you also have to heat up the water which may not get used. Six of one and half a dozen of the other I think.

What I'm speaking of is the same concept as your electric water heater except we can get it with a gas heater also. My house is mainly gas with only a few items running from electricity. I seldom lose my electricity & when I do, my provider is extremely efficient on getting the problem solved...even in snow storms. I think that an hour has been my longest wait!!! My current tank heater only holds enough hot water to last a very short time in the event of a power outage. I understand the problem of losing power to the unit will affect when I have hot water. Washing dishes & taking showers are my two only real concerns & of those two, taking showers is my MAIN concern!!! I just really wanted to know how well the tankless system worked & if it failed frequently or not. If I don't have hot water to wash my dishes, I can put off washing them for a day or so; but I cannot go without my HOT showers!!! Actually, I could wash my dishes in cold water until I got my hot water restored & then redo them in hot water. Reliability is what I was looking into. I feel semi safe with my tank system because that's what I've always had. However, I have absolutely NO experience with the tankless system & just needed to hear what others thought. I must say I've received some EXCELLENT ideas here today Now when I speak with the repairman, I'll have some good questions to ask & not be a total ditz!!!

If I have to have another water heater, I am going for the tankless one. The biggest thing about it that I like is the efficiency of it. It is supposed to save a ton of money and you never "run out" of hot water. I haven't read any reviews on them because I don't really need one yet but that is where my attention will be if I do.

That has been my thinking. Unfortunately, I think I'm at the point to where I'll need to make a decision!!! I had started out doing my own research & as normally happens with me...I came up with more questions than answers. I'm notorious for NOT believing the hype sellers put out & where better to get honest opinions from actual users than on myLot???

I'm not familiar with this concept as applied to an "around the house" hot water supply,but I do have an electric shower that works this way...so long as there's a (cold) water supply and power hooked up,I can have an instantly on hot shower whenever I want,regardless if the central heating or boiler is on or not-so I think it's a great idea! So long as the unit is reliable it should give no problems,but as with any electrical equipment,YMMV...
