Greywater heat recovery with warm side agitation
This heat recovery device replaces the floor drain in a common residential shower. A large circular pan joins flush with the shower stall floor and funnels greywater into the drain piping. The circular pan contains the heat transfer device which preheats the incoming cold water and recovers approximately half of the heat that would otherwise be lost. The incoming cold water travels through a water turbine where it rotates an impeller. The impeller is magnetically coupled with a rotary whisk. The rotary motion continuously washes the draining greywater over a spiral warming coil. The spiral coil transfers the heat to the incoming fresh water as it travels to the shower's mixing valve.
