Temperature 

The water temperature is quite important, especially if you are the type who like toasty hot water.

So your task is to find out the average temperature of water in your living area and then look for that specific temperature in a heater. In case you are living in a cold area, you need a strong water heater.

Gas and propane water heaters are perfect for folks who live in cold climates since they are very powerful and effective.

Proper size 

How small should your water heater be? It depends on the number of people using hot water in your family. How many faucets and baths do you want to accommodate?

Answer these questions and you will know which water to buy.

GPM

Another factor to think of is the maximum GPM or gallons per minute that a water heater produces. Morning or evening is typically the time when we use lots of hot water.

You need to make sure that the water heater is capable to supply hot water during that time. By evaluating the GPM rating and choose a specific propane tankless water heater that matches, it is possible.

FAQs

Best Small Propane Water Heaters For RV & Cabin

How much propane should a water heater use?

You can calculate the amount of propane a water heater use using BTUs rating or British Thermal Units. BTUs are used to measure the amount of energy required to heat a pound of water by 1F.

Propane requires 91,500 BTUs per gallon in one hour. A small tankless water heater gives 40,000 BTU/hour, which is equivalent to 1.5 gallons of propane per day.

Do you save money with a tankless water heater?

Yes, you can save some bucks with a tankless water heater. The amount varies though. Energy Star said that you can save up to $100 per year, while Consumer Reports thinks the number should be $80.

To know exactly how much, you need to consider the family’s water usage. A large family will use more water, thus spending more money to pay the bill.

How long do propane tankless water heaters last?

We know that a tank water heater can last a maximum of 12 to 15 years, but tankless units can stay much longer. On-demand water heaters can last up to 20 years with proper maintenance. The reason why these beats can stay durable for a long time is that they are less likely to expose to corrosion.

Can propane tanks be left in the sun?

It is not ideal to leave your propane tanks in the sun. Though propane tanks need to go through regulatory stress tests when produced but better be safe than sorry. Find it a shade, mate.

How does cold weather affect propane?

Cold weather can affect the performance of propane tanks. When the temperature drops below -44 degrees Fahrenheit, propane begins to boil, producing less vapor and lower the tank pressure.

Do you need a water softener with a tankless water heater?

Yes, adding water softener to a tankless water heater is a great idea. Though tankless water heaters have no tank to store water, mineral buildup still occurs since water flows through the heater. If you live in a region famous for hard water, water softener is a must.

The bottom line

These 6 best small propane water heaters will change the way you live your life forever. They bring more comfort, versatility, and efficiency to your house. Enjoy immediate hot water everywhere in the house!
