Powered by Natural Gas
This is the first and the main feature of the tested unit. Since it uses gas to heat the water, there is no need for massive electricity consumption. It still requires electricity to operate but the power consumption is minimal.
Fully Computerized Safety Features
This model comes with the latest safety features and even better, they are computerized so you don’t have to worry about any complications. All you have to do is just throw your worries behind your back and enjoy the hot water this heater provides.

It offers 2.5 gallons per minute and many users claims that this model may be one of the most durable water heater on the market today. The water flow looks low when compared to the first model highlighted in this article, but it is actually sufficient for two showers or a shower and a sink.
This technology means that the unit uses the most appropriate or the lowest amount of energy at any given moment in order to heat up the water. Thanks to this feature, we are looking at 99.8% energy efficiency, which is very impressive and can save you lots of money.
For Water with 62 Degree Fahrenheit and Above
If you are planning to use this particular model, you must know that it only works perfectly in climates where the temperature of the water is 62 degrees Fahrenheit or higher. In those situations, it will power a shower and a sink without any issue. If the temperature of the water is more than 70 degrees Fahrenheit, you can even use it for two showers at the same time.
This model uses natural gas and will satisfy even the highest requirements. In essence, it is small but also powerful (6.6 gallons per minute for water flow), hence can be used for more than just ordinary applications.
The heater on this particular model has a BTU rating of 144.000 which is impressive. Yes, there are higher values present as well, but not in this price range.

0.81-0.83 Energy Factor
If you are looking for a tankless water heater that offers the best performances for the money, then this model is for you. As you can see, the energy factor is 0.81-0.83, one of the best in the class.In terms of efficiency, this model really delivers.
In our buyer's guide, we will list down all the features and factors that must be taken into consideration when looking for radiant floor tankless water heater. After going through this article, we do hope that you will be able to determine which model is best suited for your expectation.
Here we can see that there are two main types. You can choose between a tankless water heater which uses gas or propane and the ones that use electricity. The second type can be furthermore divided into two categories. Point of use and the whole house.
Point of use will feed just one sink or shower with hot water. The whole house will obviously provide hot water for all sinks, showers, and faucets in that home. Electric units are extremely small and they can be installed under a sink, but they have lower hot water flow output.
Gas-powered units offer a much higher water flow, but they are more complicated to install. They obviously use gas, but there are two versions. The ones that use natural gas, and those that run on propane.
For most of you, natural gas models are a better choice. Keep in mind that all of them can be divided into older (models that have on and off switch) and newer which use modulating technology.
The hot water heater for radiant floor heat must come with self-modulating technology. As the name suggests, you will be able to use a device which is clever or capable of adapting. In simpler words, this means that the water heater will use the lowest amount of gas or electricity to heat up the water. They use a valve which features different open or closed processes.
Gallons per Minute Flow
As you may recall, we have mentioned this factor several times in our reviews and this is an essential factor if you are thinking about using water heater to heat the house. It refers to the water flow per minute. For example, we have a model that offers 10 GPM. It obviously means that 10 gallons of hot water is available per a minute. This amount will vary and it is unique for each model. You can browse models between 1 and 20 GPM.
Another factor which has to be taken into consideration. How efficient your new tankless water heater is? At the moment, gas-powered, models with a tank have 67% efficiency. A tankless is much better with 80%. Some are even rated at 99.9%, which is impressive.
All this means that you will save money on a monthly basis. On average, you are looking at 30-60% of money saving by installing a tankless water heater. This may be higher or lower and it will depend on the tankless water heater itself and the use of hot water. We must say that in this case scenario, more is better.
You were able to see that some models require specific ventilation. This refers to the gas-powered units only. It is an added expense when installing the unit, but it is a one-time investment and it isn’t as expensive as you may believe. Nevertheless, keep in mind that you will have to make some adjustments to the installation place.
Some units can be installed indoors and outdoors, while others must be installed indoors only. Make sure to use the manufacturer’s recommendations or you can damage the unit, which isn’t a smart thing to do and repair will cost you!
If it isn’t installed properly, you will lose a warranty, which is the second main issue here. Hence, it is advisable to seek professional for installation.
One of many reasons why a homeowner will choose a tankless water heater is the space saving. We all know that these models are the best when it comes to the amount of space they require. In order to get the best one, look for dimensions and the installation place at your home.
