No-tank Natural Gas Water Heater- Buying Guide
All of these 8 models are excellent in terms of quality, performance, and price. In the end, it is all about getting the right model for the right job.
Still, deciding which of the above-reviewed model is right for you?
There are a whole lot of variables that you need to consider before you shell out your hard-earned money for an NG no-tank water heating system.
This buying guide will help you narrow down the right one for your needs.
If you exactly know what to look for, choosing from the many most efficient models available should be easier than ever!
TEMPERATURE DEGREE RISE IN YOUR AREAS
The average water supply inlet temperature differs based on location. So, an ideal model in the South might not work well in the North. Again, a unit might work at 5500 feet altitude, but not at all at 10000 feet.
So, consider the altitude where you plan to use the system.
YOUR HOT WATER NEEDS AND UNIT’S FLOW RATE
This is by far the most crucial factor to consider when choosing a no-tank model for your home. You’ll need to determine beforehand how many gallons of SIMULTANEOUS HOT WATER you need and how much the system can pump out per minute. This will help you determine the GPM or gallon per minute that you’ll need to meet your needs.
For example, for a load of laundry and two showers, you’ll need a model that is rated to deliver at least 5.5 GPM (1.5+2.0+2.0=5.5) for your area.
Let’s have a look at the estimation
|Appliance||Gallon per minute (approximate)|
|Standard hand sink||0.5|
|Standard shower head||2.0|
|Washing machine||1 to 1.5|
|Kitchen sink||1 to 2|
|Dishwasher||1 to 2|
|Whole home||up to 6|
Check the spec sheet or product information page for your selected model, find the line with your degree rise, and learn how many GPM it will deliver at that degree rise.
Calculate the total GPM you need and compare it to the one you get from the chart.
Don’t forget to check the model’s BTU and make sure it is suitable for you. In general, the larger the house, the more powerful model you will need. Getting the right power requirements will ensure that the system is ideal for your hot water requirements.
An energy-efficient model will deliver you hot water within a short time and thus help you to save your money.
Energy efficiency of a NG model is expressed as EF (energy factor). It refers to the ratio of energy delivered as hot water to the unit’s total energy over 24-hour. EF take into consideration the efficiency of the source of energy to the unit’s standby energy losses plus the energy loss when it cycles on and off. The greater the EF rating, the more energy-efficient the unit is.
We recommend going for a unit that reaches about a minimum 60% efficiency rate.
PRODUCT DIMENSIONS AND COMPATIBILITY
This type of unit doesn’t require much space to install since it has no tank. But you need to be sure you have available space to install this system.
The natural gas-powered unit needs to be installed in locations that have proper ventilation outside. So, you should check its compatibility with your home.
Purchasing an NG on-demand hot water heater is an investment that could last you for 10 to 20 years. This variation comes with different price ranges. However, they are more expensive than their electric counterparts. But, it is just the initial buying cost. They are less costly in the long run.
When purchasing a system, make sure it is of high-quality so that you won’t have to worry about its service life.
We hope this extensive review of the best tankless natural gas water heater was helpful.
In spite of the high upfront cost, when it comes to both long-term utility perspective and cost-effectiveness, any of these 8 models might just be the right option for you.
Armed with this information, you’re just one step away from enjoying an efficient water heater with full confidence that it’s the best, most economical choice for your needs.
You’ll love the convenience and endless savings of these no-tank natural gas variations.
