Marey's water heater is the best choice if you're looking for a feature-packed gas powered hot water generator.

Marey’s gas-powered water heater is a tankless hot water generator with a digital temperature panel for better controls. This water heater features a portable, compact design so you can carry it anywhere and get access to hot water almost effortlessly. It runs on 2 D cell battery or it can be hooked to a propane gas tank. Do note that Marey’s water heater only uses gas while the water is flowing. Because it requires no electricity to operate, it will save you at least 60% on your monthly energy bill and who can say no to that?

There are two types of models for this line of water heater, one is made for liquid propane and another model powered by natural gas. You can adjust the gas and water flow thanks to its control knobs that are laid out on the front of the unit for easy access. The digital panel indicates the water temperature so you’ll know if the temps need adjusting. It’s pretty lightweight so you won’t have any trouble lugging this baby around. The Marey water heater is ideal for outdoor use but it can be hooked to your home’s gas line too.

This water heater is prone to water leaks because there are air and vents installed to the outside of the unit itself. This is a major design flaw that causes the cold air to be trapped into the vent and cause the unit to freeze. To prevent this, you have to disconnect the unit and drain both hot and cold water pipes every time you use it. This makes the Marey water heater cumbersome to use if you’re in a rush. Some customers are also complaining about the overall quality of this water heater.
