Compare On Demand Water Heaters

It's the holiday season and your peaceful suburban domicile is overflowing with houseguests. You need a nice, hot shower to soothe your nerves, but you're in line behind your in-laws and cousins. In times like these, you'll be glad you installed that new tankless water heater in your garage.
The idea behind a tankless system is that it heats the water as you need it instead of continually heating water stored in a tank. Tankless heaters have been the norm in much of Europe and Japan for quite some time, but they haven't gained popularity until recently in the United States -- largely due to the green movement. If you're a good candidate for a tankless system, you can save a substantial amount of money every year on your monthly bills while at the ­same time conserving natural gas. Tankless heaters also last about five to 10 years longer than a tank heater, take up much less space and provide you with an unlimited amount of hot water. Below is a list of few of the most popular tankless water heaters on the market.

Stiebel Eltron Tempra 24 Plus Electric
The Good: An electric model featuring the top-notch temperature control which is developed by its automatic, Advanced Flow Control mechanism. These systems are known for providing the utmost efficiency and comfort for customers.
The Bad: Three year warranty is only valid if the installation is done by a professional. This does not really count as a negative point as installation of a tankless water heater should always be done by a professional due to the fact that these systems can be hazardous if not installed correctly. It is quite obvious that dealing with systems that heat water on demand can be really dangerous.
Bottom Line: It has been rated as one of the best water heater on the market. Its biggest strength are reliability, satisfying water temperature and flow.

Rinnai RL75iN Natural Gas Tankless Water Heater:
The Good: This product is preferred by customer due to the fact that it offers the largest temperature range of most of the models that are in the market. On top of that, Rinnai RL75iN can be converted from natural gas to propane when needed.
The Bad: This water heater does not really have any negative aspect to it but the fact that there have been few reports with regards to its quality control issue. This is a normal thing with the huge amount of manufacturing and Rinnai is known for providing hassle free customer service.
Bottom Line: It has been known as the beast of on demand water heating. This machine can power many appliances and bathrooms at the same time. Quality issues are very rare and hence should not be dwelled upon when considering this product.

Takagi T-KJr2-IN-NG Indoor Tankless Water Heater:
The Good: The water heater turns itself hot if in case of overheating. On top of that, it includes a frost guard for colder temperature and hence is very popular in areas where the temperature tends to be cold pretty often. In addition to that, the water heater also has large connections which allows for a higher flow rate.
The Bad: Limit warranty is only valid if the installation is done by a professional. But as stated earlier, this does not really count as a negative point as installation of a tankless water heater should always be done by a professional. It is quite obvious that dealing with systems that heat water on demand can be really dangerous.
Bottom Line: Known for being one of the most efficient gas-fed models which is suitable for smaller homes.
