Why choose a tankless propane water heater?
A tankless propane water heater is basically an “on-demand” water heating system. Therefore, you don’t need a tank to store the water. Most families find that propane tankless heaters are far more dependable and energy-efficient than traditional models.
Low energy consumption
In a propane tankless water heater, water flows through a coil. This coil is heated by a gas ignited burner, which in turn warms up the water. A tankless water heater only operates and heats the water by the time you need it, in contrast, to always boiling water saved in a tank. Because a propane tankless water heater uses a very hot flame you don’t need to keep water sitting in a storage tank, eating up energy dollars while it waits to be used.

Tankless Propane Water Heater Buyers Guide:
Ok. So now that I’ve shared some product reviews along with my recommendations, I want to equip you even further to make the best decision for you and your family. These are the things to consider when making your purchase:
Tankless Water Heater Flow Rate:
The critical factor which you must consider when purchasing a rinnai water heater is the rate of flow. Rate of flow measured by GPM. Rinnai tankless water doesn’t possess any tanks or reservoirs, which means that all of the heating is done in the flow pipe.
The rate of flow determines how much-heated water you get per minute. This means that the higher the flow rate, the higher the quantity of hot water you will get. The majority of the tankless water heaters available in the market provide you with a flow rate ranging from 4 GPM – 8 GPM. On the other hand, the Rinnai propane tankless water heaters offer you a flow rate ranging from 6.5 GPM – 9.8 GPM.
Propane as a Source of Power
Another critical feature to consider is the power source. Different models of tankless water heaters available in the market have different power inputs. For Rinnai water heaters, the power sources are divided into three main categories: electric, propane, natural gas, and solar-powered.
As compared to propane-powered models, electric tankless water heaters consume more electricity. Electric tankless water heaters consume a double amount of BTU units compared to those powered by propane. If you want a high energy-efficient tankless water heater, then solar-powered models are ideal because they consume very little energy, and their performance is also exceptional.
Propane Water Heaters vs Electric Water Heaters
Now, although the focus of this article is on propane water heaters, I still want to cover all of the bases. If you’re not quite sold on propane and are still considering an electric tankless water heater then you need to be knowledgable about the elements.
The heater that provides maximum output is observed to consume a high amount of electricity. The majority of the propane tankless water heater is available in convertible heating options. With this, you can change its heating output as per your climatic condition.
This unit’s output is set at 120 degrees Fahrenheit, which can be used at any decent temperature. But the manufacturer provides you with an amazing when it comes to changing the British Thermal Unit (BTU) . These water heaters are equipped with a powerful and eco-friendly propane burner.
The BTU ratings of Rinnai water heaters are considerably high and lie in 150000 to 199000.
Energy-Efficient (or Energy Factor EF rating)
Everyone prefers to purchase energy-efficient products, and it is essential too. That’s why most people like the products of brands that offer low consumption of power and maximum output. For propane-powered Rinnai tankless water heaters, they are categorized into two groups: highly efficient models and super highly-efficient water heaters.
The tankless water heaters are usually energy start rated, which means that they will provide you with the best output for consumption and efficiency. The majority of these Rinnai tankless water heaters consume 4000 BTU or even lesser per gallon of water.
Place Where the Water Heater Will be Used
For its installation of this unit, you will have to figure out the place of use, whether you will need it for indoor requirements or outdoor requirements. The majority of the people make a big mistake here, affecting the maintenance of their product.
Some people install the outdoor propane tankless heater inside the bathroom and the indoor model outsider. Thus it becomes complicated for them to maintain their product. If you are purchasing a gas-model for indoor requirements, make sure that this model has CO2 and NOx ventilation. For the maintenance of the outdoor unit, you will have to prevent it from the cold temperature.
Propane Tankless Water Heater Installation
Finally, you will also have to keep in mind the installation when you are purchasing your Rinnai tankless water heater. Installing a Rinnai tankless water heater will cost you approximately $1,500 to $2,000. The majority of the Rinnani water heaters available in the market come with preassembled parts so you can easily install the product. While installing the unit, you will have to make sure that the bathroom has two pipes, one for cold water inlet and the other for hot water outlet. And read the manual for guidance on periodic maintenance.
Error Code 11 What is it?

Error Code 34 What is it?
The error code 34 means that there is a problem with the combustion in air temperature.
