Our Marey 5L unit is a 2.0 GPM tankless water heater, that can be run with propane or natural gas. It uses an automatic electrical pulse ignition with no standing pilot light, and requires no electrical hookup since it is operated via (2) D-cell batteries. Both the water flow and gas flow can be adjusted simply with the control knobs on the front of the unit, and it also has a winter/summer knob to allow more control over water temperature by opening gas to additional burners inside the unit. This unit also contains multiple safety features, such as gas leak and overheating safety controls, flame failure safety sensor, high-pressure relief valve, and an anti-dry combustion safety device.
This unit is easy to setup/install, comes with a 5-year warranty, and has great customer support!

Let me tell you why I've decided to sell these heaters. My 40 gallon water heater went out. I had heard about the savings to be had by using a tankless water heater. I was and I still am very happy with the performance and the $25-$35 a month I've seen my electric bill go down. I have a 2 bedroom 1 bath and bought the ECO 110 ( 3 GPM ). It works so well I have the temp. control set very low and I still get hot water that I can't use without mixing it with the cold. The instructions that came with my unit made it very easy for me to install in a few hours.
In the pictures there's 2 charts, average ground water temperature and temperature rise. Add the two and this would be the outlet temperature.
Tankless: To determine the size of the tankless hot water heater you need, you’ll need to calculate how much hot water you’ll need at one time, which is called the flow rate. Flow rate is measured in gallons per minute (gpm). The table below provides typical flow rates for typical household hot water applications.
Bathroom faucet 0.5 - 1.5 gpm
Low flow kitchen faucet 1.2 -1.8 gpm
High flow kitchen faucet 3.0 - 6.0 gpm
Dishwasher 1.0 - 2.5 gpm
Clothes washer 1.5 - 3.0
To determine the gpm you need, add the GPM's of the major fixtures or appliances you expect to be using simultaneously. As an example, if you typically run the kitchen faucet (1.5 gpm) and the dishwasher (2.5 gpm) at the same time, you’ll need to heat 4.0 gpm of water. These heaters get the water very hot to the touch and you would seldom run just the hot water at full flow.
In todays economy who can afford to keep water hot 24-7? These heaters only heat the water as it is being used. They supply endless unlimited hot water. Take a small business or Church where days might go by without using hot water. The water is hot and the electric meter is running but it's not being used. 20% of the utility bill is from heating water and these heaters save 60% of that. These heaters provide these assets.
