Unlike several other sub-par water-heating units, this one isn’t noisy. It’s essential to keep in mind that external temperatures will impact this model’s capacity. The tankless device will need more power for heating water to your desired temperature if the water entering it is too cold. Therefore, if you live in a cold area, you may notice a difference.
Although the water does not become warm instantaneously, it does not require too much time to heat up. You will need to wait for a minute or two at most. The water is hot enough to make tea or instant coffee. In addition, this water-warming unit features an excellent design.

What makes this Marey Power Gas model better from other versions is that it has a feature that offers protection from freezing. It prevents water in pipes from freezing in areas where winters are too chilly. Additionally, there is also an energy-saving feature in the form of a winter/summer switch.

2020 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.
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.
