Buyer's Guide

Proper Installation

The company recommends that the tankless water heater installation should be performed by a licensed contractor who is trained to handle the plumbing, gas, electrical and venting aspects of a tankless water heater and is aware of all local and national gas fuel codes. Having a non-licensed professional perform the installation can cause operational and performance issues.

Location of Installation

The clean, modern and space-saving design of Rinnai Tankless Water Heaters gives you the flexibility to install on virtually any wall inside your home—not just in the utility room. And to save even more space, you can even mount a Rinnai Tankless Water Heater on the outside wall of your home.

Rate of Flow

The flow rate is one of the most important features when it comes to getting a water heater. It is practically measured in the GPM which is sent through the pipes. Since there are no tanks or reservoirs present with the Rinnai Tankless Water Heaters, the heating is done through the flow pipe. This rate of flow determines how much-heated water you will get in one minute.

So, the higher the flow rate that you have with your heater, the higher the quantity of hot water is what you can get. Generally, tank-type heaters come with a flow rate of 4 GPM to 8 GPM. But when it comes to the Rinnai Tankless Water Heaters, the flow rate is roughly around 6.5 GPM to 9.8 GPM. Therefore, you should select one considering your hot water requirements.

Venting

Depending on placement within the home, interior models of Rinnai Tankless Water Heaters can vent vertically through the roof or horizontally through an exterior wall. Rinnai offers multiple venting options for the super high-efficiency models that offer optimum safety and performance. Not to mention convenience and ease of installation for your installer.

The different models from the manufacturer mean that they will have different power inputs. So in terms of power source, the Rinnai Tankless Water Heaters offers mainly natural gas options.
