Tankless water heaters: the next best thing in home plumbing

Hello everybody and welcome to another of my blogs! This edition is all about tankless water heaters, which are finally common in America. When I was growing up in Italy, all water heaters were tankless. In fact, everywhere in the world uses tankless water heaters besides America! It is fascinating to me that in a place with such innovation and technology some things are still so antiquated. But that is the way of things. I am excited that for the first time many American companies are making tankless water heaters, and more of the European brands I am familiar with are exporting here as well.

 

If you have not already heard of them, let me take a moment to explain what a tankless water heater is. They are a completely different kind of water heater from what is normal in America. In most American houses that I have seen, the water heater is a big tank of water with a heating element inside, which heats up the tank capacity full of water. It is like these electric kettles you can use for making tea. All day, the heater brings water up to temperature and keeps it at that hot temperature so it is ready when you need it. And then when you take a shower, you draw water from the tank, and the heater adds more water and starts heating that. It is a simple design and it works well, but it has many flaws.

The biggest flaw is that it is so massive! Having a big tank full of hot water takes up a lot of space, and if you do not have a basement, you have to sacrifice a closet or entry room.

 

Another flaw is that even though a tank water heater will give you hot water whenever you want it, it will only give you the amount that is in the tank. So if two people shower one after the other, the last person will probably run out of hot water, and then they have to wait for the heater to get the rest of the tank warmed up. It is very limited for what you can use at one time or for the length of time you can run taps or shower heads.

 

The final flaw of this design is that to keep the tank hot for when you want hot water, the heater must run on a low level all day and all night, even when you are not using the taps or doing laundry. It wastes energy even if the tank is very well insulated.

 

In Europe and the rest of the world, we have solved all these problems! We use water heaters that have no tank. More information is found on tankless.reviews, but here’s an overview: tankless water heaters are simply a box with a series of heating coils where the water goes inside the coil instead of around them, as they would in a tank. So water is heated as it flows through the panel. What this means is you get a unlimited amount of hot water, whenever you need it, since it is heated as it comes. Well, I should say that it is constant rather than unlimited. You can only get how much flows through the heater at one time, but you can have that amount of water for as long as you want.

 

This used to be something Americans could not have, and I found it very frustrating in the first couple of flats I lived in here before you all discovered tankless water heaters. But you are finally catching up to the rest of the world, and this is very exciting. So I want to encourage all of you to explore them, if you have not already! There are so many benefits. You will not have a limited supply of hot water, so you can take showers after somebody and still have heat. And you will save lots of money on your electricity or gas bill because you are not keeping a tank warm all day for no reason. I also, and this may be a European thing, love the convenience of having such a small heater in the place. I fit mine next to the sink in my old plates cabinet.


So, what do you need to know before you buy one? Like I have said, the only limit on your hot water use is the amount you use at once, instead of sequentially. You can have 3 gallons every minute for unlimited minutes, but probably not 6 gallons every minute. If you want to make sure you will be able to use several things at once, you will have to find a large enough heater for that maximum amount of water.

We also in Europe use what are called low-flow taps to make each use take less water. And finally they are more expensive than tank water heaters, but since they are new there are many tax credits that you can get when you buy one here in the USA! You will save on electricity money and space, and have a much more comfortable existence.

From us to you! They are definitely something every DIYer should consider when refitting a home.
