Most people use hot water for multiple purposes like bathing as well as for running the dishwasher. The tankless water heater has specialized in manufacturing and improving on demand tankless technology. When anybody needs water for simultaneous use, one way to get proper flow of water is to get a single large heater for the whole house. Other option is to install a separate water heater at each point where it is needed. This also reduces heat loss of water flowing from a single point to other far away points. Electricity is really expensive the way traditional water heater uses it but on demand water heater is an energy saving option.
After the tankless water heater has been installed, it requires regular cleaning and maintenance so that it can function properly and provide the benefits to their users. If the water heater is flushed properly with a mild acid like white vinegar once a year, it will remove the mineral deposits which can damage the inner lining of the machine. If the water is particularly hard, it can contains a lot of minerals. Then flushing can be done twice a year, if necessary. Flushing on demand water heaters whose heat exchangers are blocked by the lime scale and hard water is very important and must be done before it breaks down.

Takagi T-KJr2-IN-NG Indoor Tankless Water Heater Review
“We also installed a Takagi tankless water heater when we installed a new bathroom in a part of the house that didn't have plumbing. It’s right below the sinks and about 14 running feet from the shower head. It comes on quickly works reliably and provides the hot water on demand for much less than a conventional tank based system would. Especially in an unheated crawlspace in the at 8000' in the Rocky Mountain foothill west of Denver. It is not rated for this altitude but works well. All the plumbing leading to/from this is insulated and resistance heat tape protected to keep it from freezing.”
Things to Consider When Buying The Best Tankless Water Heater
Choose the right size/heating capacity
To get the most out of your water heater, you need to choose a model that is just the right size for your household’s needs. Getting one that has a heating capacity much lower than your needs will result in water not heating to the desired temperature or a very slow water flow rate or both.
Conversely, getting a heater with a heating capacity much larger than your needs is an unnecessarily expensive investment. To get the correct water flow rate your heater must have, try adding the flow rates of all household appliances using hot water that you run at the same time. These could include showers, tubs, washers, sink, and dishwashers. Here are some of the average flow rates of common appliances:
- Dishwasher - 1.3 gallons per minute
- Clothes Washer - 3.3 gallons per minute
- Shower/bathtub - 2.5 gallons per minute
- Bathroom/kitchen sink - 2.2 gallons per minute
Remember that appliances in your homes might have different flow rates. Be sure to do some research.
Be mindful of the heater’s dimensions
If you live in an apartment somewhere in the city, you’ll know just how precious an extra space is. In fact, it is highly likely that you don’t have the luxury of having some extra space since builders these days tend to utilize every square foot of a city apartment.
As such, it is important to be as precise as possible when measuring the available space where you plan to install the tankless water heater. Make allowances for plumbing, venting, etc.
Shall you go with a gas-powered or electric-powered tankless water heater? The answer, of course, varies depending on your location.
Generally, gas-powered heaters are more economical than electric heaters. However, they require that you have the necessary gas plumbing and supplier in your locality and there is also the need to worry about venting systems, which could potentially increase installation cost. Do the math and figure out which type of fuel source would be more economical in the long run.
Tankless water heaters
have become quite popular when compared to the regular storage tank based water heaters. There are many justifiable reasons for its growing demand. It frees up space. In times of rising energy bills, it uses less energy as it does not need to keep water hot all the time regardless of use. Most importantly, it also removes the risk of water leakage and damage that can result from it. With a tankless water heater, it is possible to get limitless hot water as when required. The only thing that needs to be taken care of is that it needs to be flushed regularly to remove the calcium and mineral deposits that can accumulate and reduce the efficiency of the heater. Too much accumulation and reduce the life and lead to damage as well.
Each tankless water heater has some pros and cons. They have something to distinguish with the other competitor brand. Some people may require an indoor water heater while some may need to for outdoors like to give a bath to the pets, to fill the pool or simply to carry one where they may not get running hot water. Similarly some people want a single heater for the whole house, while some may need to have a single heater for each point of usage. Before making any decision, it is necessary to evaluate all aspects before finalizing.
