Recover gray water energy

[Christophe]

Yes that's the first thing to do ... take a temperature measurement "farthest" in the house.

If the water has already lost 20 ° C in the pipes "naturally" there will not be much to recover!

Thank you all.

My goal is to know if there are small models of pac or a pac recovered from an existing device to try to test this principle. Even if the average temperature is around 20 degrees, it makes a lot of energy.

Not really, the temperature (in fact, the difference of) is to be related to the volume of gray water ...

A fridge is a miniature cap ... it remains to be seen whether it is easily adaptable.

Hello,

I'm looking for a water-water heat pump that would be able to recover the energy contained in gray water to heat a hot water tank.

Volume of the gray water collector to be sized according to the heat pump.

Thank you for your contribution.

Hi rodolpheb
too complicated!

You install a 50 liter flat tank
between the shower and the drain.

so after 2 showers,
you will have filled the tank with 50 liters of water at 40 °,

instead of making them disappear in the energy bin

(summer bypass and lifetime warranty)

too simply

Ou
preheating tank, in which you pass what you want, waste water or solar panel,
the exchange is done at 15 ° (seen on this forum)
