Key features to consider for the best natural gas water heaters:
The following section helps you to easily choose one among the best natural gas water heaters:
Energy-efficiency:
The key purpose behind using a natural gas wall heater is it provides efficient heat output. During the operation, much energy is not consumed. You can measure the efficiency of the gas heater through energy efficiency (EF). It depicts how efficiently heat is transferred from the heating element into water.
It is better to go for a higher energy factor. This is because the higher the energy factor offered with the heater the more would be the efficiency. Typically, the energy efficiency of these heaters varies between 0.5-0.6. Few of the high-end models come with an energy efficiency of up to 0.8.
Flow rate:
Once sufficient heat is produced inside, Gas Water Heaters need to be transferred to the output. This is where the flow rate comes into play. You have to get an understanding of the flow rate and compare it between different models. Based on this, the purchase becomes easy. Generally, the flow rate is calculated in terms of GMP (gallons per minute).
The hot water flow will get stopped only when the heater attains its maximum heating ability or passes above the threshold. In case you want to have a continuous flow of hot water all the time you use, make sure you measure in the exact requirement.
Capacity:
It is important to look at the storage capacity of the heater since these heaters do not have extra storage spaces for water storage and reheating. These heaters function on a comprehensive instant heating functionality. It leaves no room for an additional area of water storage. You have to wait for the water to warm up. After that, you will get instant water as soon as you turn on the heater’s switch.
In the decent quality natural gas water heaters, there are no issues like reheating, thermal loss, and shortage of warm water. No need to wait for the hot water. Make sure you check what the total storage capacity is and then proceed for the purchase.
Concluding Note:
Without any safety concerns, these natural gas water heaters provide constant hot water supply. Most of them come with superb flow rates and heat efficiency.
