[Greenbuilding] Technology for long hot showers

[sanjay jain]

Nick,

Please elaborate on why you think recirculating hot water is not "environmentally kosher".

I would have thought it would be the most energy and water efficient 
(except the fog system - thanks for that Reuben) way to take a long 
shower. You are essentially reusing the water over and over again, and 
the energy required to maintain desired temperature would be less than 
trying to use a heat recovery method. No?

Sounds 
like more trouble than it's worth to me.  And the re-heating could be a 
long way from being environmentally kosher.  There is already such a shower 
in existance round here. It is called a quench shower. I have never seen one, 
and I don't expect to.
 
A 
greener way and long hot showers don't go together well but, if you insist on 
trying, at least the capital investment will be returned more quickly than when 
taking kosher short showers.
 
You 
may retrofit a solar water heater could make a huge dent in the heating cost. 
You might even enjoy some very pursuasive assistance from the government to do 
this.
 
You 
might be able to install a drain water heat recovery device. It could be more 
practical than solar, and can save about 35% of the heating 
costs.
 
Neither of these do anything about the water and I submit the best bet 
here is to try to use the water subsequently elsewhere rather than fiddling 
about with it in the shower. Recycling grey 
water is not very effective or useful for most people, particularly for 
those who take twenty minute showers.
