HXflatbox – horizontal WWHR for shower

The HXflatbox is a horizontal WWHR (Waste Water Heat Recovery) unit that is intended to be placed under a bath tub used for showering. It can be easily retrofitted in an existing bathroom, but note that it is too large to fit under a normal sized shower cabinet floor.
Another installation option is to integrate it in the floor or in the roof of the floor under the  bathroom.
