We recently built a deck off of our second floor kitchen. What was once a window has been opened up to become a rough opening for a door. Of course, there was baseboard heat running below the window, and I need to route that heat under the floor now so we can install the door. The floor and walls are finished and we're trying to minimize the amount of demo we have to do. The plan is to route the copper under the door itself, since there's more than enough depth under the door for both the copper and new framing for the threshold. This is in an outside wall, and will be thoroughly insulated with expanding foam to prevent any freezing. (we're in New England)
It's a really tight fit and I don't want to have to pull apart any more of the plaster wall than necessary. So my thinking is to sweat brass elbows on both ends of the horizontal run under the door, ahead of time. Something like this: http://thd.co/10VtQav This will allow me to slip that horizontal run under the door into place, then I can simply thread the short runs that come out of the wall on either side into those, using these http://thd.co/12w6FGQ
this would allow me to assemble the components ahead of time, making it easier to put together and avoiding major demo on the wall (and sweating the fittings inside the wall cavity, which I'd rather avoid).
So I guess my main question is - can I use threaded fittings in a forced hot water heating system like this, or am I asking for leaks?
Thanks!
