you need to install a heat exchanger between
your boiler and the poly pipe. oxygen diffusion
occurs thru the pipe . an slowly eats out your
boiler an any steel or cast pumps. water does
not leach thru pipes but oxygen molicules do.
other methods are oxygen barrier pipe like wersbo this could be costly if you have in floor
heaT. types of heat exchangers you could use
are super storr stainless steel water heaters or
a tube style exchanger copper to steel . talk to
a new heating contractor. good luck.
