Leaky Heat Exchanger
To the Editor:
"Using Water Heaters for Radiant
Heat" (11/98) was a great article, but I
have one question about heat exchangers.
If the heat exchanger were to
develop any leaks, it seems possible for
contaminated water from the hydronic
coils to leak into the drinking water
side of the system. Is that really possible
or am I missing something? If such
a leak did occur, it might be difficult to
detect until someone got sick.
A second question: With so much
concern about earthquakes, how do
the California building codes deal
with preventing leaks in the pipes that
run through the floors?
