We are in the process of renovating our house. Our house is approx. 100 years old. We hired a general contractor to do all the work including the heating system. Our heating system currently only have old radiators on the main floor and the upper floor. We've asked our contractor to install new rads in the basement and create 2 zones, one for upstairs and another one basement replacing existing rusty pipes.
It seems that the HVAC subcontractor is using a combination of Pex and pex oxy barrier pipes to replace the old pipes. After reading comments on the internet regarding Pex vs Pex al pex vs Pex al pex, I'm wondering if we are working our way in to a bad situation. My main concerns is that these pipes are connecting to the old rads. Would the pipes start to corrode easily because we are not using Pex al Pex or pex with oxy barrier though out? Should they not be using Pex al pex everywhere or pex with oxy everywhere not just in some parts?
Here's the oxy barrier spec.

My other concern is that pipes get really hot and start making loud noises. We are planning to have a tenant in the basement.
Any thoughts please?
