What materials will I need for a hydronic baseboard heating system?

Asked by B Stewart

I am installing a hydronic baseboard heating system and I would like to use a tankless water heater as opposed to a boiler for the energy source. Will this work? Also, I am assuming copper is the material of choice for the piping, but what would I use as the reflective backing material behind the pipe?

A tankless water heater will be mediocre at supplying both domestic hot water and hydronic heat.

Yes, copper is the best, but that cheesy plastic stuff works well, too.

  • Caleffi has a website that is chock-full of info about this and anything else you could imagine hydronically. I also recommend their stuff over any others.

Runtal and many others make flat-panel radiators that outperform any other hydronic heat delivery system, and they are beautiful.
