Avoid: Happybuy 6L Propane Tankless

Happybuy 6L Propane Tankless Review

Happybuy 6L Propane Tankless Review: If you’re out in the market for a propane tankless water heater, we would recommend other options before the Happybuy 6L Propane Tankless.

As first-hand user reviews indicate, the water heater promises to be stainless steel and rust-resistant, but exposure to the outdoor elements may prove otherwise. In certain instances, the Happybuy 6L Propane Tankless has developed rust, which may indicate that only the front panel is stainless steel while the rest is inferior quality material.

The unit is also not a hassle-free one as it requires three adapters to work the water in and out and the propane to work with American fittings. Also be aware that this cannot run longer than 20 minutes without shutting off. And it is not designed for the indoor use.

It does remain a decent budget option. It is compact and is capable of providing warm water on the go. There are better options on the market if you can afford one of the more premium propane tankless water heaters, however.

To watch the Happybuy 6L Propane Tankless Review on YouTube, click here.

Pros:

  • Relatively inexpensive
  • Compact water heater
  • Shuts off every 20 minutes

Cons:

  • Prone to rust
  • Not suited for outdoor use
  • Low quality material

2022 Buyers Guide to the Best Propane Tankless Water Heater:

You have to consider several factors when looking for a good quality propane tankless water heater. Durability, build, price and water flow are among the essential features you should look for. If you are an outdoorsman, consider the size and weight of your unit, as it will determine whether or not it is portable.

The size, for starters, is important. A small heater may fall short of meeting your and your home’s hot water requirements, while a very big heater may be an unnecessary purchase. To determine the right size you need, you must consider your maximum uses, from dishwashing, laundry to daily showers. The total water consumption will determine the ideal heater size for you.

Secondly, you must also consider the flow rate and the temperature rise. The gallons per minute tells you the amount of water the fixture will provide at a time, and the maximum temperature the heater will rise to from groundwater level. Additionally, the temperature rise is mainly the temperature difference between the groundwater and your desired hot-water output.

Such calculations can tell you whether the appliance is suitable for your total usage, especially during peak demand hours and whether the water will be hot enough to suit your liking and needs. You must also run through the manufacturer’s manual when surveying the market for heaters.



3 Main Points to Consider:

  • Flow: The last thing you want when enjoying a hot water bath or prepping food in your kitchen is poor flow. You do not need to empty tankless water heaters since they do not have a tank. The water supply can be endless, but the flow can sometimes be a problem. Only choose models that provide good flow.
  • Mounting: Do not make the mistake of buying a heater that you cannot place or mount in your desired area. Make sure that the model you are choosing is easy to mount and has all the necessary prerequisites to install it at your preferred location. If you want a heater for outdoor use, choose a wall-mounting unit.
  • Electric vs. Gas: Both heater types have their benefits. Tankless water heaters often require large gas lines in comparison to traditional heating units. Also, gas tankless water heaters are significantly faster than their electric tankless water heater counterparts. Not to mention, they provide high water pressure. However, their pilot remains open even if you are not using water. Electric units, on the other hand, do not require as much energy. You can turn them off after you’re done using water.




What is a Propane Tankless Water Heater?

These heaters are an excellent option for heating and reheating water whenever you want. They use propane gas as fuel and provide a steady flow of water to users. People often prefer these heaters because of their low carbon dioxide emissions and their environmentally friendly nature.




Natural Gas vs. Propane Water Heater

Natural gas water heaters are only suitable for areas that get an adequate supply of natural gas. Propane water heaters, however, can run anywhere. However, propane poses a significant explosive risk since it is heavier in comparison to natural gas.




Final Thoughts on Buying a Propane Tankless Water Heater

Particularly if you live in states like Washington, South Carolina, Oregon, Tennessee, Oklahoma, where demand for a propane tankless water heater is high, you need to consider some primary factors before you select a propane tankless water heater for your needs.

In the end, remember to list down the main reasons why you need a fixture for an additional boost of hot water in your life, then tick mark the features of the prospective items against your list. The one that comes closest to what you need is the right pick.
