Buying guide

8 things to look for when buying tankless gas water heaters

1. Efficiency

One of the most important things to look for when buying a tankless gas water heater is efficiency. Tankless gas water heaters are more efficient than traditional tank water heaters, as they only heat water when it is needed. This can save you money on your energy bill each month.

2. Size

Another thing to consider when purchasing a tankless gas water heater is its size. Tankless gas water heaters come in a variety of sizes, so it is important to choose one that will be able to meet your hot water needs. If you have a large family or frequently entertain guests, you will need a larger unit.

3. Flow Rate

The flow rate is the amount of water that the heater can deliver per minute. If you have a high demand for hot water, such as taking multiple showers back-to-back, you will need a higher flow rate. Most tankless gas water heaters have a flow rate between 3 and 8 gallons per minute.

4. Temperature Settings

Some tankless gas water heaters allow you to set the temperature, while others have pre-set temperatures. If you want the ability to control the temperature of your hot water, then look for a model that offers this feature.

5. Energy Star Rating

When buying any type of appliance, it is always important to check the energy star rating. The energy star rating tells you how much energy the appliance uses and how efficient it is. Appliances with a higher energy star rating use less energy and are more efficient.

6. Warranty

Another thing to consider when purchasing a tankless gas water heater is the warranty. Most manufacturers offer a warranty of at least 5 years on their products. Some even offer extended warranties for up to 10 years. Choose a model that has a good warranty so that you can be sure it will last for many years to come.

7. Price

Of course, one of the most important things to consider when purchasing anything is the price. Tankless gas water heaters range in price, so be sure to shop around and compare prices before making your final decision.

8. Installation

When buying a tankless gas water heater, it is also important to consider the cost of installation. Some models are easier to install than others, so be sure to ask about this before you make your purchase. Installation can typically be done by a professional plumber or handyman.

Conclusion

When purchasing a tankless gas water heater, there are several things you should keep in mind. Efficiency, size, flow rate, temperature settings, energy star rating, warranty, price, and installation are all important factors to consider. By taking the time to research all of your options, you can be sure to find the perfect tankless gas water heater for your home.
