GlobaTowne carries all the Marey gas tankless water heaters. The Marey gas tankless water heaters are great for remote locations where there is no power and minimal water flow and pressure. The Marey Power Gas 16L, Power Gas 10L and the Power Gas 5L heaters will all operate without using any electricity. The Marey units operate on 2 - "D" cell batteries and require only 10 psi of water pressure making them great for camps and cottages in remote locations.
The Marey Power Gas tankless water heaters should be mounted indoors but if they have to be mounted outside then they would have to have a box built around them to protect them from the elements. Only install the Marey Power Gas units outside in a protected box only if you are in an area where it is not going to freeze. If the temperature is going to get down below 32 degrees F then you would want to drain the tankless water heater and also maybe bring the unit inside.
The Marey Power Gas 16L, 10L and the 5L heaters can operate on a small 20 lb LP tank as long as you have the correct regulator on the tank. Please refer to the installation manual for proper gas line sizing and gas pressure.
