Why choose a solar water heater HELIOAKMI MEGASUN

The internal cleaning of the tank is done by sandblasting (throwing metal beads) to create a rough surface, in order to achieve absolute adhesion and adhesion of the enamel to the inner surface of the container, giving it twice its lifespan.

The double inner enamel of the boiler, which is baked at 860 ° C, offers resistance to water with a high content of salts and makes it safe for public health.

Maximum operating temperature 95ºC

It is a closed circuit boiler and due to its operation with antifreeze, it can withstand up to many degrees below zero.
