How to choose the best propane tankless water heater?

propane tankless water heater buying guide

Choosing the right tankless propane water heater is a difficult task as there are so many options to choose from. You have to consider lots of things like price, features, power and so much more. Here are some of the factors you need to consider before buying the tankless water heater.

Water Flow Rate (GPM)

GPM stands for Gallon Per Minute, and it is applied to measure the flow rate of water. You have to decide how many appliances you want to use at the same time and add up all their flow rates. For example, the shower has 2.5 GPM, the washing machine has 2.0 GPM, and the dishwasher has 1.5 GPM. If you add that all up, you’ll get a total of 6.0 Gallon Per Minute. Now you have to find a unit that can supply a minimum of 6.0 GPM. You can also find out GPM using a 1-gallon container and timer. First, you have to find out how many seconds it takes to fill the container. Then divide that number of seconds by 60. Considering the flow rate helps a lot in finding the perfect tankless water heater. Like, if you are not using multiple appliances at the same time, then a lower flow rate is enough. However, you need higher flow rates if you are using several devices simultaneously.

Warranty and Protection

Most of the propane tankless water heaters are pretty durable and last longer than the standard water heater. The tankless water heater can give you service for up to 10-12 years, longer if it is well maintained. Choose the propane tankless water heater, which has a longer warranty and higher safety measures. This combination will provide you safety and durability at the same time. Talking about safety, tankless water heaters come with many protection systems, like dry combustion protection, anti-freezing protection, flame failure protection. Anti-freezing system releases the water residual so it won’t get clogged up by frozen water during cold weather. Flame failure protection prevents gas from gathering and building up in one location. These are some of the protections your tankless water heater should have.

Installation process

The portable tankless propane water heater is very easy to install, but the large tankless water heater is not so much. Portable tankless water heaters are made to carry around and enjoy hot water anywhere. The whole house tankless water heaters are not easy to install and have so many complex parts to fit. You probably need a professional to install it. If you have a portable propane tankless water heater that you often carry with you on trips, you should invest in a proper installation kit.

Temperature Rise

The average temperature of the water supply in your house could be 40F degrees, and it could be colder or warmer depending on the weather condition or area you are living in. For example, the supplied water in your house is 60F degrees, and you want hot water around 100F degrees, then your tankless water heater has to raise the temperature of water to 40 degrees. If you are living in a cold area, then you need a higher power tankless water heater.

Energy Efficiency and Less-emission

The propane tankless water heaters are surly energy efficient because they heat the water in no time, saving time and energy. The other thing to consider is less emission. The lesser the discharge of the harmful gas, the safer the environment will be. You should find a tankless water heater that is safe for the environment and energy-efficient.

Portability

If you want to use the propane tankless water heater for outdoor use, then you should buy a unit that is compact and lightweight. The small size and less-weight make them easy to carry around on trips. You can take them to a campaign or RVing, and also the portable tankless water heaters are very easy to install. However, they are not as powerful as the large propane tankless water heaters.

Types of Water heaters

There are five main types of water heaters. And all of the heaters have their advantages and disadvantages. Let’s see them in detail.

Storage Tank Water Heater

This is the most common water heater. You can find these types of heaters in big houses. The storage tank heaters are also known as conventional water heaters. The conventional water has a large tank to store water. The bigger the size of the tank, the more hot water it provides. There are different conventional water heaters in the market which have different fuel sources. The tank of the conventional water heater is insulated. It means once the water heats up, it will remain warm for a long time. The limitation of these types of water heaters is you can use a limited amount of water. Once the tank is empty, you have to wait till the water heats ups. Conventional water heaters are tough to maintain.

Tankless Water Heaters

So many people prefer tankless water heaters over standard storage-tank water heaters. Unlike conventional water heaters, these don’t have any tanks, so they are portable. The tankless water heater has a coil inside it. The coil heats up using a power source, and the coil transfers heat to incoming water and provides you hot water instantly. The tankless water heater comes in different sizes. The bigger size heater provides more hot water compared to the smaller tankless water heater. These have compact sizes, so they are easy to carry around. You can carry propane tankless water heaters to camping, RVing, or at mountain cabins.

Heat-Pump Water Heaters

The heat-pump water heater is heavy, and it needs more space. The heat-pump water pumps work differently compared to all the other heaters. This type of water heater uses hot air from outside or ground air to heat the water. The heater contains an air pump above it that takes in hot air and releases the cold air. These types of water heaters have tanks to store water, which makes them harder to maintain. However, the heat-pump water heater uses 60% less electricity than stander water heaters use. Less electricity consumption makes it energy efficient, and no fuel usage makes it environment friendly.

Solar Water Heaters

Last but not least, solar water heaters are the most energy-efficient of all. The heater contains the water tank, which gets heat from the attached solar panel. The solar panel absorbs solar energy and allows the water to heat up. These types of water heaters work perfectly in warm areas. The weather surely affects the heating capacity of the solar water heater.

F.A.Qs

Q. Do propane tankless water heaters are hard to maintain?

The tankless water heaters do not require much maintenance. But there are some things to consider for maintaining your propane tankless water heater. The tankless water heaters do not have a storage tank, so you don’t have to worry about cleaning the tank twice or thrice a month. One of the biggest enemies of the tankless water heater is hard water. The hard water causes havoc in the tankless water heater as it creates the insulating layer between heat-exchanger and water. This layer slows down the water heating process; however, there is a solution to minimize it. You can use a water softener to reduce the hardness in the water. There are so many different kinds of water softeners available in the market. First, check the hardness of the water and then use a compatible water softener.

Q. How many GPM is enough in a tankless water heater?

The full form of GPM is a Gallon Per Minute. It is applied to measure the flow rate of water. The GPM of the tankless water heater depends on how many appliances you want to run simultaneously. The more devices you want, the higher GPM is better. For example, If you are using two hot showers at the same time. Then you need approximately 5 gallons per minute. Similarly, instead of two hot showers, you want hot water in the dishwasher and kitchen sink, you need 3 gallons per minute of water flow. So, GPM purely depends on your needs. If you want a tankless water heater for the whole house, then the high GPM is perfect.

Q. Are propane tankless water heaters loud?

The propane tankless water heater makes minimal noise. The tankless and traditional water heaters do not have much difference in making noise. The tankless water heater has a burner and a blower motor and nothing fancy. All the noise comes from these two parts of the tankless water heater. And it is very bearable. It will get louder if the flow of the gas is not in control.
