If I were using it as part of a hot water recirculation system, I'd have
some concerns. Even if it weren't delivering water of 180 degrees.

My 14 yo house has polybutylene tubings running in the floor for hydronic
heating. So far, there has not been any leaks attributed to them, and the
boiler is original. Any concerns? What is the outcome of the class
action
re. polybuts in Canada?

Seems like the Canadian action only covers for replacement and leaks from
the acetal joints which apparantly are rare. There is really not much I can
do about the infloor tubings since the only way to replace them would be
jack hammering the whole house !! Oxygen permeability seems to be the
biggest concern. Again, not much I can do about that until the boiler
leaks. I wonder if oxygen scavengers/rust inhibitors would help.

I believe that chlorinated water speeded the degradation, and you're not
using it in that piping. Could it be that the newer couplers were used in
your installation, and that you don't need to be awaiting a failure?

You'll need pumps on both sides.

If adding a heat exchanger can solve the rusting problem, are there boilers
already with a stainless steel heat exchanger built-in to save space? Also,
by using a heat exchanger, then all those by-pass loops and mixing valve can
be excluded, correct?

How can one tell if the tubings and the joints are the affected ones? Are
there markings on them?

Also, upon further reading on the settlement, the Canadian action was only
settled in the province of Ontario. Does anyone know if the other provinces
settled, especially in British Columbia?

Problem is the coils in the floor ARE the heat exchange
surfaces.

From what I understand, the exchanger will isolate the water from the
boiler. The water from the boiler pumps through the exchanger, and the
water from the floor pipes also pumps through the exchanger, but only heat
exchanges between them inside the exchanger. That way, the boiler will not
rust out.
