Heat Output & Flow
The main reason to buy the product is reduced energy consumption as it heats water only when required. With so many brands and types of the product heat, output and flow rate is an essential check. There are two main units – one for heat output measured in BTU(British Thermal Units) or KW(Kilowatts) and other is the volume of water delivered measured in GPM(Gallons per minute). It is important to select the product with right values of both so that you get enough hot water with lower consumption of power.
The products are powered by electricity, natural gas and propane and it need to be selected based on your requirement. It all depends on what your home supports and how much capacity you need. There are few homes which have only one fuel source and in such case, one should opt of the water heater with that particular power source. But in the case of a home that supports both choosing one depends on what you need. Electric models are expensive but require less maintenance than the gas models.

The major difference is the requirement of the ventilation in case of gas or propane heaters but it is not required in case of electric models.
It is one of the most important aspects to consider while purchasing a tankless water heater. The product must have good features for better operation. It should have temperature adjustment or control system to adjust the temperature using a simple knob. Alternatively, it should have automated flow controls for right temperature settings and adjustment. The safety features like automatic power cut-off, freeze – control etc should be checked. The presence of digital display makes it easy for the user to view and analyze the operational settings. The warranty should be also checked before purchasing the product.
