Key specs explained
Flow Rate: 10.3 GPM
This rating indicates the maximum volume of hot water the unit delivers each minute. You can expect strong pressure for multiple simultaneous uses, such as a shower and kitchen sink. Compare this figure with other whole-house models to ensure it meets your peak demand without temperature drops.
Fuel Type: Propane
The unit runs on propane gas rather than natural gas or electricity. This makes it suitable for homes with existing propane tanks or lines. You will need a compatible gas supply and venting setup. Check your current fuel infrastructure before purchasing to avoid installation complications or extra conversion costs.
Temperature Control: ±1°F, up to 149°F
The digital system maintains water temperature within one degree of your setting, preventing sudden cold shocks. The high maximum of 149°F allows for effective sanitization or heating in areas with very cold inlet water. This precision is ideal for users who require consistent comfort for bathing or dishwashing.
Low-Flow Activation: 0.53 GPM
The heater turns on when water flow reaches just 0.53 gallons per minute. This sensitivity ensures efficiency by not heating water for every minor drip. It prevents energy waste while still providing hot water for low-demand fixtures like hand washbasins. Look for this spec to gauge on-demand responsiveness.
