Re: OT : Plumbing help as well
Mark,
http://www.endlessshower.com/install.htm
I'm going to install a 'home brew' heat recovery system for the
ventillation. I like heat recovery systems :o) They are up to
70%
efficient - and work well when extracting warm steamy air from bathrooms
and
showers etc... The extract air passes through a heat recovery chamber
(size
dependant upon flow rate and air speed) which heats up the replacement
incoming air.
The drainage heat recovery system is excellent, but I saw it when it was
too
late to do anything with it - and also we have 4 seperate drains.
What I
would have liked to have done was divert warm/hot waste water to a
large
insulated 'holding' tank and either extract the heat with a heat pump,
or
just simply used the waste water to heat incoming water. The shower
drain
is a clever idea because it's heating the incoming water when you need
it.
Regards
Simon
