Marey PP12 electronic controlled tankless water heater provides a maximum of 2 points of use and 2.2 GPM. This very versatile unit is great for apartments, cabins and tiny houses. As a point of use, the PP12 has wide range of home applications with a maximum flow rate up to 2 GPM. Wall mounted and with a space-saving design, this unit is easy to install almost everywhere. The unit comes with Backlit LCD Display for easy and exact temperature selection, is electronically controlled and provides fast heating on demand. With the in bare element heating technology, water and heating elements themselves are in direct contact, so the heat transfer efficiency is maximized. Whereas in more traditional tankless water heaters, the water is in contact with the metallic casing surrounding the heating coils, indirect heat transfer is much slower. The German designed alloy bare heating element provides a constant output temperature even with a low flow rate. The bare element heating also offers liming formation protection. The unit is CSA certified and it can be sold in the US and Canada. Not recommend for elevations above 2000 ft.
