Accessories

Additionally, an electrical outlet, an electrical timer and water supply lines are also needed for the installation of that type of water heater. Besides, the average time to install this product is about 2 hours. That is the reason why consumers can expect to pay a low installation fee for this model. Especially, when compared to other models which are more complicated and time consuming to install, you only have to pay a much lower charge for the installation.

Use

Furthermore, another factor which can affect installation costs is a reduction offered on certain tankless hot water heaters. Specifically, you can completely take advantage of a tax credit on products which qualify with Energy Star. This is because tankless water heaters with the Energy Star symbol are energy-efficient appliances by government standards. Also, these products are highly rated in quality, performance, and features.

Material cost

Moreover, consumers will need to figure in labor as well as material costs for other parts needed in the installation. In fact, the accessories needed for a tankless water heater include a tankless gas connector kit, termination vent kit, two-piece lead-free brass tankless water heater valve set, along with mounting hardware and fittings.

You Should Choose Gas or Electric Tankless Water Heater

Overall, gas tankless water heaters are widely available in a large variety of sizes and models for you to choose from. Gas tankless water heaters also range in output from about 140,000 BTUs to 380,000 BTUs, and they are available in commercial and residential grades.

More importantly, installation of this type of tankless heater is not as complicated as gas models since there is no need to vent. Furthermore, they can perform well and produce high energy ratings. Besides, they are also easier to maintain. In addition, electric hybrid model tankless heaters are initially high in cost. However, these heaters can heat water quicker than standard electric models.

Generally, point-of-use electric tankless heaters can offer a lot of attractive features such as the ease of installation and low cost of the product. They are also convenient for you to use under sinks, in very small areas. You can even use them near your washing machines.

In short, this type of tankless water heater is a great choice for you if you need a small water heater for boats, campers, and small bathrooms. They are insulated, non- corrosive, lightweight and attractive. The point-of-use feature can help you save water by providing quick hot water conveniently.

Choosing the Right Tankless Water Heater

Tankless water heaters will not come in specific gallon capacity sizes like conventional hot water tanks. Therefore, the question is:” How can you determine which water tank can be your needs?” For both electric and gas tankless water heaters, you should consider the demand of water at one time or the flow rate.

In fact, you can calculate the flow rate by measuring the gallons of water per minute( gpm). To find a specific flow rate, you should find out which fixtures and appliances are in use at the same time. Then you need to add these figures together to determine the maximum gpm required of the tankless water heater.

  • Shower ? 1.0 to 2.0 gpm
  • Washing machine? 1.5 to 3.0 gpm
  • Dishwasher ? 1.0 to 2.5 gpm
  • Bathroom faucet? 0.5 to 1.5 gpm
  • Kitchen faucet? 3.0 to 9.0 gpm

Pros of Tankless Hot Water Heaters

One of the greatest advantages of tankless hot water heaters is that the water is hot very quickly. Depending on the gpm of the tankless water heater, it can produce continuous hot water based on your needs.

Also, another very attractive pro is the savings that tankless water heaters provide. As water heating accounts for about 30 % of your home’s energy bills, a tankless water heater can easily cut these costs by up to 50 % savings. Specifically, these savings amount to approximately $80 every year.

Furthermore, a tankless hot water heater can last an average of 20 years. And it is also easy for you to maintain. Moreover, it is very small. Thus, you can completely put it in a lot of places which don’t allow conventional hot water tanks. In reality, the average is nearly 28 inches tall by 20 inches wide and 10 inches deep.

Cons of Tankless Hot Water Heaters

In fact, the biggest con of tankless water heaters is the initial cost of purchase as well as installation. To be honest, the tankless water heater cost is much higher than the total cost of the conventional water heater. It can take almost 20 years, even with energy bill savings. Also, remember that 20 years is the lifespan of the product, just for consumers to make up the initial cost.

Additionally, inconsistent water temperature is another con about tankless water heaters. Faucets don’t produce an instant flow of hot water as they expected. And this feature is just like conventional hot water tanks.

Keep in mind that a tankless water heater will not work to produce hot water during power outages. Also, in emergency situations, unlike a conventional water heater, there is no backup water source.

In case you have hard water, you have to install a water softener to your tankless water heater. This can help avoid problems which can occur from calcium buildup. One more thing, just remember that the life of your water heater will reduce if you don’t maintain it annually.
