hydronic radiant floor system with potable water radiators

I have a radiant floor heating system using Radiantec supplied pex & pumps in 4 rooms (each is a zone with thermostat & pump) & the system also supplies our hot water. I had an old boiler steam system with radiators for the other rooms in the house. Boiler gave out so I would like to add some zones to the system but I don't want to rip up flooring (2nd floor rooms) & would like to use hot water radiators but they have to be 'potable' i.e. made of copper or stainless steel so the water is still drinkable after passing thru. Does anyone know where I can find a US manufacturer? When I google I find mfgs in Australia, the UK and China but nothing in the US.

The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
