Top 3 American Water Heaters
American GT505PI Indoor Tankless Water Heater
Fully modulating, gas powered and specifically designed for an average home’s hot water needs. With its compact and relatively small size make, you save a lot of space in your garage or wherever place you choose to install the GT505PI.
In addition, like any other tankless water heater, the GT505PI provides hot water on demand, and as such, it is able to greatly reduce your energy bills in the long run. However, the biggest strength with the GT505PI lies in its high hot water delivery rate, which is an impressive 9.4GPM. With such a delivery rate as you will see below, you could run about three showers and a dishwasher at the same time and still run the kitchen faucet.
Among the best American water heater makes, the GT505PI has a solid place among the top three makes. It uses a very robust heat exchanger made of the strong copper alloy to ensure that hot water gets into all your water home’s water points with no hitches or disappointments. In fact, it is almost impossible to get lukewarm water with the GT505PI unless you use the heater for large commercial purposes. But despite the strong heat exchanger, the GT505PI is still a portable and relatively lighter water heater. The overall water heater construction is also incredible and has a durability lifespan of up to fifteen years.
The ability to deliver hot water consistently at a delivery rate of above 9GPm requires a strong system. It is not a surprise then that the GT505PI accommodates a maximum of about 199,000 BTU input and a minimum of 11,000 natural BTU. On the other hand, the heater’s ability to link up with up to three other similarly powered water heaters means that you could confidently run the water heater for commercial purposes and never get disappointed.
With an energy factor of 82%, you can be certain that your energy consumption ratings could lead to massive amount of money saved in the more than ten years you should expect this device to serve you.
The GT505PI comes with an inbuilt temperature controller, an automatic electronic ignition and a range of safety features such as the air fuel Ration sensor that helps maintain proper combustion. It also comes with an overheat protect system, a flame failure protect function as well as an internal freeze protection system.
American GT 540 NIH Hot Water Heater
With an energy efficiency rate of 95%, the GT540 NIH is hands down the most energy efficient Tankless water heaters from AO Smith manufacturers: the people who make American water heaters. It has a relatively small size, a strong primary and secondary heat exchangers, as well as smart system, protect functions. In addition, the natural gas powered water heater is built with one of the most efficient systems as you will see below.
2 Efficient Heat Exchangers
The GT540 comes with two strong heat exchangers; a primary commercial grade copper-made heat exchanger as well as a secondary heat exchanger made out of steel. This combination enables the device to produce as much hot water as any average or big home will need. In fact, the devices’ efficient heat exchangers are built to supply hot water efficiently to restaurants, bars or any other medium sized businesses with no disappointments at all. In any case, the water heater is fitted with both an easy link and a multi-link function that help combine the powers of more than one heater.
To start with, the GT540 is tankless, which means it is already more likely to be energy efficient than any tank water heater out there. Tankless water heater’s don’t waste any heat since they deliver hot water on demand, remember? However, the energy efficiency of this device by far transcends that of many other tankless devices. Its construction, the presence of an inbuilt temperature controller, the presence of a venting function that measures about 100 feet in length and natural gasses’ generally energy conserving functions makes the device efficiently consume about 95% of all the heat it produces.
High and Continuous Water Delivery
Ideally made for both residential and commercial purposes, this device is able to deliver hot water continuously at a rate of about 10 GPM. With this power, any home could enjoy hot showers, run their dishwashers as well as run any other water point without feeling inconvenienced at all. But it is also important to note that the ability to run up to 199,000 BTU on the maximum is a feature that makes this device really reliable and convenient.
It has an overheat protect function which is also backed up by a power failure system should it fail, an internal freeze protect function, a flame failure function as well as an Air Fuel Ration sensor that helps maintain proper combustion of the unit. In addition, it also comes with a 15-year limited warranty and an over current protect.
American GT705NI Indoor Tankless Water Heater
Sleek, smart features, and highly energy efficiency are just some of the reasons why this water heater often fairs so well in American water heater reviews. It might be a bit more expensive than standard tankless models, but its high quality reputation transcends that of any other natural gas powered water heater. And while it has a high water delivery rate of above 9GPM, it could serve more than four hot water points and retains the continuous flow of hot water. In other words, this is a device you can confidently buy both for residential and commercial purposes.
The GT705NI has a thermal efficiency rate of about 90%, which means in the more than ten years you could live with the device you will save thousands of dollars in terms of energy bills. It works with BTU of up to 199,000 and has very strong heat exchangers. In fact, the copper alloy constructed heat exchangers are so good that you could enjoy continuously flowing hot water despite the underground temperatures at your basements. And in the worst of scenarios, the American GT705NI is built with internal freeze protect features and internal heaters that work together with the main heat exchangers to guarantee you a comfortable life with a never ending supply of hot water.
Great Water Flow for Residential and Commercial Purposes
With a water flow rate of 9.8 GPM, the ability to link up with other tankless models for more hot water and the general superior constructions have always made the GT705NI a reliable water heater. In addition, the reliable hot water delivery also makes the device very versatile. You actually don’t have to compromise on any other activity when you need hot water in the showers. That is to say, you could run about two showers simultaneously, wash the dishes stress-free and have your kitchen faucet running; all the same time because you have a great water heater.
Since this water heater has a very high thermal efficiency rate, you could enjoy not paying as much as half the amount of money used to pay in energy bills with tank devices. Depending on how often you use this water heater also, you could save up to 30% of your annual energy bills.
In addition to an electronic ignition, the water heater also comes with a range of safety protect functions like; and air fuel ratio sensor to help maintain a proper combustion, an overcurrent function, internal freeze protection and a temperature control button.
With the high quality construction, a high thermal efficient function and compact design, it is no wonder that the American water heaters are some of the most reputed and well rated heaters in the online market. They give you a great value for your money; they are durable and most likely will meet your home’s water heater expectations. However, what should always be important to you before settling on a tankless water heater is to be certain that it could serve your needs with efficiency. Water heaters are meant to last, so choose yours wisely.
