How the Haws Tankless Water Heater Works

Operating the new

Haws

tankless water heater is similar to using any traditional water heater system. However, it is very important that all of the set-up procedures and operating instructions are carefully read to ensure maximum performance and energy savings from the water heater.

The

Haws tankless water heater does not store hot water like a conventional tank-type water heater. It contains high powered bare wire technology heating elements that are capable of heating water instantly on-demand. Whenever there is a hot water demand, the patented flow meter within the heater recognizes the demand and initiates the heating process. This meter measures the water flow rate while two thermistor sensors measure the incoming and outgoing water temperature. This information is transmitted continually to the microprocessor controller which determines the precise amount of power to send to the heating elements to heat the water to the desired temperature. The Haws tankless water heater only uses as much power as is needed to meet the demand by fully modulating the heating elements from 0 to 100%.

It is important to keep in mind that all tankless water heaters are subject to a maximum flow rate. If this flow rate is exceeded, the heater will not be capable of fully heating water. The amount of water that can be heated by the tankless water heater at any given time will depend on the model selected and the incoming water temperature. See diagram on below to determine the maximum flow rates. Since a tankless water heater eliminates the ongoing thermal losses caused by storing hot water in a tank, there will be a significant energy savings compared to a conventional tank type water heater.
