Noritz water heaters work on demand. They only heat water when necessary. When a hot water outlet is opened or hot water is required by its system, the heater will sense this and start its operation accordingly. Instead of wasting energy by storing hot water unneccessarily, tankless water heaters provide only as much hot water as is needed at the time.
What are the differences between a tank water heater
and a tankless water heater?
Tank water heaters store and heat water continuously, thereby incurring higher operating costs, whereas tankless water heaters only heat water as needed. In addition, tank heaters hold a finite supply of hot water while tankless heaters provide an unlimited supply.
How much money can be saved, if a Noritz tankless water heater is used
in place of a storage tank?
The California Energy Commission estimates that a water heater uses approximately 25% of all energy consumed by any household, which can cost hundreds of dollars per year. Using a Noritz tankless water heater will allow a home to use up to 50% less energy for water heating.
Which model Noritz tankless water heater best suits my application?
The best way to size a tankless water heater for any application is to estimate the necessary flow capacity to be used at peak demand. For residential use, this will most likely be the maximum number of showers that may be used at a time, multiplied by the flow rate of the showerheads. Only qualified plumbers or contractors should calculate this rate. Once this maximum flow rate is calculated, consult the specifications for each heater to determine which model best meets your situation.
[Controlling the Heater]
What temperature should the water be set at?
The set temperature of the water heater depends on how it will be used. A comfortable shower temperature should not be much higher than 100 F (temperatures above 120 F will cause burns). Lower temperatures will also prevent scale deposits from affecting the operation of the heater.
How can I change the temperature on the water heater?
Every Noritz tankless water heater comes standard with a digital control panel which allows you to adjust the water temperature. In certain models, the control panel is on the face of the heater. For other models, the control panel can be wired and installed separatly. The water temperature is displayed on the control panel and can be adjusted using the up and down buttons.
