Although the scope of this construction project has almost completely focused on the ground floor of my 3 floor Victorian (for budgetary reasons), I used the open framing on the ground floor as an opportunity to run the radiant heat for the second floor of the house. This radiant floor will operate at a lower temperature than the ground floor because it runs under the existing oak strip flooring of the second floor. We plan on installing engineered flooring for the ground floor as I've been told it's more compatible with radiant heat.

Hi, When you say operate at a lower temperature, do you mean that the actual temperature of the water in the tubing will be lower (like come from a different boiler or something) or that less heat will be trasferred to the rooms above because the floor is less conductive than engineered wood? If the latter, I would think the temperature would equalize out, but it would take longer to warm up.
Is the water temp going to be less than 80 degrees? And why no heat transfer plates. I'm considering radiant and I've always seen the extruded aluminum plates that the Pex is snapped in to.
M, the actual operating temperature of the water in the tubing will be lower. The ground floor will operate on a separate system. It uses an "on demand" hot water system that also provides all of the hot water needs for the ground floor. I may rent the ground floor which is why I put it on a separate system. Even if it were on the same system, it can be zoned so that different rooms/floors get different amounts of heat.
I don't know the exact operating temperature. I'll ask the contractor and get back to you. Because I live in San Francisco, an area with a temperate climate, I didn't need to use the aluminum plates (I asked the same question). There is more than enough heat transfer.
