How Do You Choose the Best Propane Tankless Water Heater?

Tankless propane water heaters provide hot water solutions for a variety of uses. These versatile units can supply an entire home or be a cost-effective solution for guest accommodation. 

However, there are various models available that you can hang from a tree while camping exists. It is best to comprehend the technical aspects described below in order to make a sensible choice.

Flow Rate (GPM)

When picking the best tankless water heater for your needs, flow rate which refers to how much hot water the unit produces may be the most crucial consideration. 

Although certain European models are measured in liters per minute (l/min), there are 3.78 liters in a gallon, it is normally measured in gallons per minute (GPM). It’s crucial to realize that the heater will have to work harder and provide less GPM the colder the mains supply. 

When a heater is installed in the northern U.S. as opposed to the warmer southern regions, the flow rate can vary by several GPM. Manufacturers frequently offer comparison data to aid consumers in making purchasing decisions.

Household Size

Consumers should take their household size and the number of fixtures they need to power into account when thinking about a tankless water heater. In general, tankless water heaters take some time to heat the water to a temperature that is suitable for showers, and higher temperatures can reduce water pressure. 

Moreover, the number of simultaneous showers that a manufacturer’s water heater can power is often specified. Multiple showers can be powered more easily by units with larger. 

Can a propane tankless water heater work for a whole house?

Certainly. There are models that can give hot water to households of different sizes. The setting of the propane tank, which was described in the previous question, should also be taken into account. 

Tankless water heaters for the entire house are a terrific way to reduce your energy bills. These deliver hot water on demand to all of your home’s fixtures.

How big of a propane tank do I need for a tankless water heater?

It depends on the heater’s requirements. Those for tiny houses and camping may be able to operate for several weeks on a typical 20-pound bottle and you can go for a 40-gallon water heater.

On the other hand, for large-capacity heaters, larger propane containers are available, or a permanent tank would be necessary. In this regard, you can go for a 75-gallon gas water heater

120-gallon propane tank: If you use propane in one or two appliances, such as a stove, fireplace, clothes dryer, or tankless water heater.

250-gallon propane tank: This tank might be used to heat the entire house for a modest home, often one that is no larger than 1200 square feet.

Indoor vs. Outdoor

Tankless water heaters powered by propane can be purchased as indoor or outdoor units. Indoor tanks are tiny enough to fit in areas much smaller than a standard water tank, but it is important to take into account getting the gas supply from outside because it is nearly always kept there.

An outdoor variant may be much easier to install. The only pipe needed to enter the house is the one that distributes the hot water. It needs a supply of cold water and, of course, the gas must be connected. While some portable types require an electrical connection, most run on batteries. 

Can you run out of hot water with a propane tankless water heater?

A tankless system might still be overloaded with demand even though it cannot run out of hot water. This cannot be done with a single tap; you can take as many showers as you like and the water will remain hot.

Ventilation

Ventilation is essential to both the combustion process and the subsequent removal of hazardous carbon dioxide. While it’s typical to have separate ducts for each, some heaters use concentric vents, which are essentially two pipes stacked on top of one another. 

Even though concentric forms are more expensive, low-cost PVC is frequently used. Another choice is stainless steel, which is also more expensive. Although side-venting variants are also available, top-venting models are more typical.

Energy Efficiency

By efficiently converting fuel to heat energy, a high-efficiency water heater reduces energy costs. The highest efficiency rating available for some of the best propane tankless water heaters is 99 percent; as some energy is constantly lost, 100 percent efficiency is not attainable.

Moreover, the Uniform Energy Factor (UEF) is an independent measurement standard that was established by the U.S. Department of Energy (DOE) in 2017. This enables prospective purchasers to compare products accurately. The efficiency of the water heater increases with the UEF number. 

Are propane tankless water heaters worth it?

Yes, it will be a worthwhile investment to switch to a propane tankless water heater. 

“The U.S. Dept. of Energy claims that tankless water heaters are more energy-efficient than traditional water heaters and can save consumers anywhere between $25 and $107 annually. A tankless water heater will be 24% to 34% more efficient if your hot water usage is little (less than 41 gallons per day).” Source 

How long do propane tankless water heaters last?

Tankless gas water heaters should last 20 years or longer, which is twice or three times as long as tank-style heaters. The lifespans of tankless electric units are typically 7 to 10 years.

How Much Does It Cost to Install a Propane Tankless Water Heater?

A propane tankless water heater typically costs $500 to $2,000 on average. Liquid propane can be used in the majority of natural gas-powered appliances. Some could need a converter if they were made for natural gas originally. 

Additionally, propane-powered tankless heaters are available. For individuals without access to natural gas or who cannot afford rising energy prices, propane is a decent alternative. Although propane is more expensive than natural gas, it is typically less expensive than oil.
