PRODUCT ADVANTAGES

Marey heating elements are made from a single piece of cast

aluminum, so there will never be water leakage non electric

leakage in the heating chamber. Marey heaters also have an extra

stainless steel water ow channel instead of the previous layered

plate style, so no matter how your water quality is inside the

heating element, it will provide a long life of service.
