About Marey 

Marey was founded by a Puerto Rican entrepreneur named Mario Reyes in 1955. However, they only started producing tankless water heaters 40 years after they were founded. The company is 10 years ahead of most of its competition. 

In Puerto Rico, Marley quickly emerged as the premier brand before expanding across South America,  North America, the Caribbean, and eventually across the globe.

Types of Marey

Marey is manufacturing two types of tankless water heaters. They are:

  • Gas Heaters
  • Electric Heaters

They feature cutting-edge technology, such as energy-efficient technology, despite the low price. Being eco-friendly products they do not harm the environment.

Salient Features Of Mary Tankless Water Heaters

With Marey’s product range, customers can expect superior quality along with convenient features. Marey stands out from its competitors based on the following factors:

Models Based on Temperature

Is the water temperature in your area generally high? With these Marey tankless water heaters, you minimize energy consumption as the water is heated on demand. If you live in the Caribbean, you can save up to 60 %  by using less energy. 

Temperature Control On An Automatic Basis

A feature that Marey calls ‘Smart heating’ makes its water heaters automatically adjust the temperature. By modulating the amount of energy used for heating, the heater achieves optimum water temperatures automatically. This reduces wasteful energy consumption. 

Overheating protection systems are also built into these heaters, enabling them to turn off automatically when a preset temperature is exceeded.

Patented Heating Elements

A number of Mayer’s models use Nickel-chromium (Nichrome) heating elements, including the ECO series. Chromium oxide forms a protective outer layer of this substance after it is heated for the first time.  A layer of protection from oxidation increases the life of the heating element inside.

Powered By Batteries

You can use the water heater without electricity because it is powered by 2D cell batteries. In times when power blackouts may occur in your area or home, you may use this tankless water heater as a backup option.

Anti-Freezing Protection

Its water discharge valve can be removed when the temperature outside is below zero. The heater uses the pipes to store water so there is no chance of freezing water. 

Eco-Friendly

Marey aims to protect the environment and improve the global environment. As a result, they prioritize the creation of the most environment-friendly, budget-friendly, and innovative tankless water systems in order to reduce global warming and CO2 emissions.

Startup with Low Pressure

Fortunately, since it operates at low pressure, it can supply warm water to several floors at once. Only 8 PSI water pressure is necessary for it to function, so it can work with low water pressures as well.

Online Customer Reviews of Marey Tankless Water Heaters

Marey heaters generally have favorable reviews by customers online. Customers praise their durability and smart technologies for a low-cost price. It is true that some customers complain about the low quality, but the low price makes it justified. 

As they work without electricity, the customers are happy with these heaters who have electricity problems in their home. 

Installation And Prices for Mary Tankless Water Heaters

Getting professional help when installing electric heaters is recommended by Mary. In general, homeowners say that installing the system is fairly straightforward with the help of the simple and easy installation guide.

On the flip side, it would be best to hire an HVAC specialist proficient in installing identical models for gas heaters. It is the case with all gas heaters since working with gas can be dangerous, especially if you aren’t familiar with plumbing practices or building codes. Installation guides are available for gas heaters, just like for electric heaters. 

In terms of price, Marey tankless water heaters range between $150 and $600, making these models affordable. 

Maintenance of Mary Water Heater

If properly maintained, Marey tankless water heaters might last for at least twenty years or more. The gas heaters need annual maintenance, and both the gas heaters and electric heaters require regular cleaning to give excellent performance.

Warranty and Customer Service for Mary Hot Water Heaters

Several ways are offered by Mary to assist customers. To contact a member of the team, simply dial their number or send them an email. Aside from that, the website and user guides address the most commonly asked questions.

Marey has service centers with both customer service and technical support in Texas and Puerto Rico, so clients in those locations can receive even more support.

Unlike many other suppliers, Marey provides five-year warranties on its water heaters. In addition to covering all component defects, the warranty includes first-year maintenance. In the event of damage during installation, interior dismantling, or extreme weather conditions, your warranty is void. If you want to receive a warranty, it is very important to register your water heater within 30 days of purchase.

Where to Buy a Marey Tankless Water Heater

All of the Marey water heaters listed above can be purchased on Amazon. It allows you to check out quickly and easily. There’s even an Amazon installation service you can purchase.

Frequently Asked Questions

What size tankless water heater do I need for a family of 2?

30 to 40 gallons of water are sufficient to be used by two people per day. The tankless water heaters with 3 to 5 GPM would be best for a family of 2. In terms of electricity, 10 to 18 kW is perfect.

Can a tankless water heater heat the whole house?

Tankless water heaters with high GPM are designed to serve the whole house’s hot water needs. Tankless heaters with a flow rate of 7 GPM or above works as the best whole-house tank water heater.

If a tankless water heater is sized properly as per the hot water requirements, it never runs out of hot water.

Unlike traditional tank systems, a tankless system does not have the potential to explode. They come with advanced safety measurements, ensuring no explosion will occur.

Finding the best Marey tankless water heater reviews in 2022 can be a daunting task. Researching the best products available can take hours. Marey has always been at the forefront of producing water heaters. In addition to being convenient and gas-saving, these heaters are also extremely energy efficient.

You must consider several parameters when choosing the best product. For the high flow rate of water, I would recommend Marey ECO270 220V as the best tankless model. For less demand of hot water, you can go for Marey Power Pak Plus
