Choosing the right water heater for your remodeled or new bathroom/kitchen can be a headache. You have to do a lot of research and worry about capacity, space, leaks, and then you still may not find the right solution. Luckily, there is a space and money-saving option which also supports multiple fixtures.
Marey is just one of many manufacturers that creates tankless electric water heaters, which provide endless hot water on demand. This has been their craft ever since the company opened its doors in 1955. For this article, we have tested this particular water heater for you in our Marey ECO150 review.
Here we have gathered together information about the technical characteristics, real-world application, warranty and more, for your convenience. The following sections contain all you need to know about this particular point-of-use water heater.
Marey ECO150 Specifications
You will find that mounting this model is a fairly easy task. With dimensions of 8.7 x 3.5 x 14.2 inches, it is a very compact water heater for its medium-to-light capacity. As it weighs only 10 pounds, putting it up in most locations won’t require any extra equipment.
Not much energy is needed to power this water heater. At peak performance, this unit pulls about 14.6kW of energy at 240V. Your service panel will need to have at least a 70-amp double pole breaker installed, as the unit can draw up to 60.8 amps at maximum capacity. Also, to safely support your home appliances alongside this water heater, we suggest a minimum household electricity supply of 150 amps.
The manufacturer suggests that this tankless water heater must not be installed more than 40 feet away from the fixtures requiring hot water. Any more than this and you will be losing hot water pressure along with the savings these machines provide. Temperature adjustment is made easy with the digital LCD display that allows the user to accurately set their desired hot water temperature.
Customer Support and Warranty
Consumers can contact the company’s customer service via telephone or email. The various online resources their website offers can provide answers to common questions. These include perfect user manuals, a FAQ section, help finding professional installers, and more.
This unit has a 5-year warranty on parts. By following the manufacturer’s instructions, your machine could last many years beyond the warranty.
What to Expect from Marey ECO150?
Given the instructions provided by the manufacturer, your best bet would be to use this machine as a point-of-use on-demand water heater. It is possible for this unit to support 1-2 bathrooms, depending on your location and climate. Given that the heating element is made from one single piece of metal, leaks are less likely to happen.
For example, you could expect a 3.5GPM output flow of hot water if your ground water is about 80°F (26.6°C) and the desired temperature is around 105°F (40°C). A flow of this capacity could power up to two standard showers and a faucet.
In a colder climate, where the water temperature may be closer 55°F (12.7°C), you will get a diminished hot water supply of 2GPM. That could support 2 low-flow fixtures or 1 regular shower head. It is possible to use these in a cold climate, but mostly in small 1 to 2-person households without high hot water demands.

- 5-year limited warranty on parts
- Flow rate can support up to 2 bathrooms in a warm climate
- Temperature is controlled with a digital display
- Doesn’t work well in cold climates

With the right application, a single water heater could cover your entire home. Given the budget-friendly price, you could purchase multiple units to supply all of the fixtures in a larger home. While this depends on your location, the performance of this on-demand water heater looks promising, even in temperate climates.
Once you calculate your required flow capacity and compare the cost of more powerful tankless water heaters, you may decide that this heater outshines much of the competition in the mid-performance-range.
