 1.  Rinnai RU130iN Sensei Super High Efficiency Tankless Water Heater

Rinnai RU130iN Sensei Super High Efficiency Tankless Water Heater, 7 GPM - Natural Gas: Indoor Installation


The Rinnai Sensei SE+ tankless water heater is a brisk compact model that is installed for indoor purposes. This best tankless water heater saves on space of up to 16 inches as compared to a traditional storage tank. It is compatible with using both natural gas and propane. The energy-efficient unit ensures that neither water nor gas goes to waste. This is made possible with the Circ-Logic technology that services your requests faster according to your scheduled patterns.


The performance is optimal at a flow rate of 7 GPM which connects your utility appliances, kitchen faucets, and showerheads. It is advised to have a temperature setting of 120oF which works well with all faucets. It's even more convenient for you to work or study at home since the noise emission is minimal. As far as I am concerned, quiet settings are most suitable for activities that call for tight bubble concentration.

Smooth Installation

If you are planning to install by yourself, you should seek broad knowledge on the installation details. The instructions on the manual may only give specifications on the temperature, gas flow pressure, flow rate, and all that. However, the only time you can apply the control settings is only after a successful installation. Information may vary but in case of confusion, you can get a professional plumber to do the work for you.

Key Features

Recommended for : The Rinnai RU Series tankless water heater has earned and sustained the title of the best tankless gas water heater without fail. The Circ-Logic technology is an effective strategy that works on increasing the water flow rate plus reducing water storage. You will only have to wait for about 10 seconds until your faucets have running water. The only thing that may pose a challenge is whereby your connection lacks a return line which causes a delay in hot water flow.

Smooth Installation

For most folks that have done installation and set up without calling for a professional, they have had to go through trial and error. It is always a new adventure when DIY projects are involved. I assume that most of you have tried one of the latter projects for either home improvement or personal gains. The first time always seems clueless however advanced steps make you sharper. If you have done something before, it's obvious that the next time you do it, it will take you less time. Some may suggest that this is task that anyone can take on but it is all not true.
