Best Propane Tankless Water Heater – Indoor Installation

Propane tankless water heater is an ideal solution to heat water if you don’t have a direct pipe connection to natural gas delivery. Propane as fuel is cheap and clean. But, the significant advantage of a propane water heater is that it doesn’t need lots of investment into the installation.

Best Propane Tankless Water Heater

By choosing a tankless water heater, you are already saving lots of money annually on heating water. You spend money on heating water only when you need it. There is no standby cost, even if you leave your home for several days. Now since you choose propane as the fuel for tankless water heater, you are saving, even more, every year. Propane is a great heater, and thanks to its burning properties, it can heat water fast. 

However, just like everything in life, it has its advantages and advantages. In this buying guide, I will try to explain which propane tankless water heater is good and give you several products to pick. Not all propane tankless water heaters are good for you. You need to decide on your own what you need and how much money you want to spend.

What is Propane Tankless Water Heater?

Propane tankless water heater is a device that you install in your home that will heat water. Powerful propane water heaters can heat water for a whole house, or you can buy less expensive propane water heater and install them on one pipe to heat water only on that pipe.

Since these water heaters are tankless, then you should know that they are small in size and don’t require a tank. They will take less space in a room and can be mounted on the wall. Since there is no tank, no money is burnt on heating water in a tank, just like is the case in traditional tank-based water heaters.

Propane is a fossil fuel that burns good. It requires less propane to heat water than, for example, natural gas. If we compare propane water heaters to electric heaters, then you see a clear advantage of propane as fuel. Propane as fuel can heat water at a much higher rate, and you will never get cold water in the shower even if you are living in a cold climate.

TOP 10 Best Propane Tankless Water Heaters

A good deal of propane tankless water heating manufacturers has more than one model. Because of that, in the following list, you will see several products from the same manufacturer. That only means that a specific manufacturer is an expert in propane water heaters production.

Camplux AY132 5L 1.32 GPM

First on the list is not really made primarily for the house. In fact, Camplux AY132 5L is portable, and most of the time is used on traveling in a camper. But this propane-fueled water heater can be used outdoors as well. Without a problem, you can enjoy a hot shower even if you are camping in high mountains without electricity and other modern world services. As long as you have propane in a tank, you will have a hot shower.

In the package, you will get a gas regulator as well as a showerhead. Since it comes with a showerhead, then you know that the primary purpose of this outdoor portable tankless water heater is showering in nature. This water heater can heat up to 1.32 gallons per minute. The maximum temperature is 46 °C, and the minimum is 8 °C. Don’t worry about overheating or freezing because this water heater has a built-in protection system. It also has a flame failure, high water pressure, low water flow, and dry combustion protection. With all these protections, you can be assured that nothing will go wrong. Even if you install it indoors, it has an oxygen depletion sensor, which will make sure there is no dangerous level of CO2 in the air.

Camplux BW264 10L 2.64 GPM Digital Display

If your family needs more hot water, then to be safe, it is best to go with the BW264 model, which has 10l, which is twice as much as the AY132 version. Also, this more powerful Camplux model is giving 2.64 gallons per minute, which is also twice as much. But that power comes with a much larger size. This water heater is also portable and can be used outdoors. However, it is most of the time used as a fixed unit on a camper rather than a device that you carry with yourself on the mountain.

It has more weight and larger size than the previous model, and that makes it less portable and somehow harder to carry with yourself if you are going for a hike. But the larger size also has some other additions like digital display, which will tell you the exact water temperature. Just like AY32, BW264 also comes with a gas regulator, shower head, and all protection systems Camplux builds in their products.

All the previously mentioned benefits of Camplux propane water heaters apply to this model, as well. All protection systems are included as well as a digital temperature display.

Camplux comes with more protection, but it also has a much higher price than the Eccotemp. Eccotemp is slightly easier to carry because of the weight and size. It can easily be used for outdoor camping, even if you are traveling on foot.

If the previous water heaters are too weak for you, I am sure this one is strong enough unless you are living in the castle.

Warranty is included in this model as well, and since all the V series models are basically using the same technology and the only difference is in power, the same Warranty is in all of them. Even though this water heater is powerful, it is still compact and be installed even if you have very little space for it.

How Does a Propane Water Heater Work?

Just like all other water heaters work, cold water is pulled into the system. In the middle of the system is a fire which uses propane to burn. That fire is used to heat water. Hot water is then released back into the pipe and used as you like. 

Propane tankless water heaters don’t need to store water, but they need a chimney. When any type of fossil fuel is burned, there will be more or less smoke. That smoke needs to leave a room. Also, extra ventilation is required to release any unwanted gases and CO2. When burning propane, oxygen is burnt, and the product is CO2. High levels of CO2 can be dangerous.

Propane fueled water heaters are best for off-grid places. They are best for places like cabin, camper, or even a house that is not connected to a natural gas pipe. Propane refueling is done via propane truck, which will deliver propane at your door. Be careful when refueling because pressure needs to be monitored all the time. It is best to leave propane refueling to professionals.

How Much Propane Does A Tankless Water Heater Use?

We know that tankless water heaters will save you money on working only when there is a demand for hot water. But how much propane will be used is hard to tell because it depends on the usage and needs of hot water. Some calculations are fluctuating over the internet, which say that families with two members will spend 15 gallons of propane per month. For five members, the usage raises to 40 gallons per month.

In other words, if we say that propane is around $2, then for two people, that is $30 for one month, which is not much. For the five-member family, that amount grows to $80, which is still not a lot.

Does A Propane Water Heater Need Electricity?

If you thought that gas-based water heaters don’t need electricity and will work even when there is a power outage, you were wrong. Modern tankless water heaters that run on fossil fuel still need electricity because all technology in them needs electric power. Many of them have a monitoring system, protections, and LEDs. All these features require electrical power.

Many propane tankless water heaters use electric ignition. Without ignition, there is no heating. However, some water heaters use gas as a fuel as well as solar power. These hybrid water heaters can work even if there is no electricity in the house.

Benefits of Using Propane Tankless Water Heater

Propane tankless water heaters have many benefits. They are the ultimate off-grid solutions.

Save Money

Propane is a gas that gives lots of heat, and on the market, the price of this gas is low. Being a tankless water heater also means money is spent only when there is a demand for hot water

Installation

Installation is not expensive, and all you need to do is install a water heater and connect it to a propane container. On the other hand, natural gas needs to be connected to the city gas line, and that can be complicated as well as an expensive investment.

Eco-Friendly

Propane, when burned, is not releasing any dangerous gases. It is natural and friendly to the environment.

Long Lifetime

Tankless water heaters will serve you for many years. The average tankless water heater lifetime expectancy is around 20 years.

Tips For Buying A Propane Water Heater

There are many brands on the market; however, on this list, you will find only three of them. I think these three brands are leaders in propane tankless water heater field.

Temperature 

Make sure the water heater is capable to heat water. When groundwater is cold more heating power is needed.

Size

Some tankless water heaters are huge, and you will hardly get space for them in your small home. Always make sure the water heater will fit in your room.

Water Flow

Water flow is essential if there are more members in your home. Never use more hot water than a water heater can deliver. You won’t have hot water, and the water heater will work at full capacity.

Protection

Some water heaters have built-in safety measures that will help propane water heater work correctly in all circumstances. Also, some of them have sensors to detect gases. You should carefully consider these options when buying propane tankless water heater.

Summary

Thanks to this excellent buying guide on how to buy the best propane tankless water heater for your home. I hope you won’t make a mistake. If you read the whole guide, I am sure you are more than qualified to make the right decision. Good Luck.
