I am planning my grey water system and I have an idea on how to recover the wasted heat.
I am trying to both expanding and closing in my porch.
It is to become an attached green house.
I have built a vermicomposting filter for the kitchen grey water. It occured to me that the filter will retain some of the heat from the water that passes through it.
So if I run all the grey water through it, I will get an added boon,beyond the water itself.

The pipe would be 1 1/2". The plan is to run it from my washer,down and over the to shower, drain in the room next to it, down the wall to the first floor and pick up the kitchen sink.
Check valves on each fixture and an open vent in case of any clogs.
The pipes should be painted black ,I suppose,to pick up more heat.
Have to be careful though, worms can't survive at or above 95°. Perhaps insulation is a better idea.
The tote that holds the worms and their bedding will distribute the water to the wood chipped black berry patch along side the drive way.

So some questions:

I know liquid water holds some heat, relative to a below freezing environment,no matter how cold it is, but should I be concerned that the washing machine water will be a detriment? We only wash with cold water.
I could send it another direction, and skip the filtering entirely.

Do you thing 1 1/2" pipes running outside of the wall will freeze solid or crack from thermal shock when hot water hits it, or is 1 1/2" PVC tough enough to deal with this abuse?

Might this work ,or am I missing a huge flaw the plan?

Wow, thank you very much! The concept is sound,so I feel good about pushing forward on execution.
My vermicomposting filter is intended to have a seasonal shower directly over it, but the temptation to include plants as well is very strong...
 
Who among you feels worthy enough to be my best friend? Test 1 is to read this tiny ad:
