I have a 2900 sq ft house in Central NJ that is heated by a hybrid (mixed) steam / hydronic baseboard system (house came this way!).
I have a largish enclosed unheated front porch (38x 10) with four six ft wide x 4 ft high thermopane windows on the north facing side and an 8 ft x 4 ft thermopane window on the east facing side. It is over a crawl space.
I am contemplating installing 3 six ft lenghts of high output slantfin baseboard on the north wall. For a variety of reasons, its not possible to put a baseboard under one of the end front windows or on the east window.
I am planning to use the existing circulator pump and install two zone control valves with the porch as its own zone. I only need to get the temp in the porch up to about 50/55 degrees.
All this is probably too much info for the basic question...
Should I use 3/4 copper or 3/4 PEX for the lines? It's a longish run ( 37 feet as the crow flys) from the porch outer wall to the furnace... and its NOT a straight shot.
I'm handier than the average home owner and have installed/repaired hydronic systems myself several times successfully.
While I have all the tools I need for copper, I don't have any for PEX. I'm considering using short copper risers to the baseboard and transition to PEX in the crawl space if I use PEX... othewise harddrawn copper and elbows all the way if copper.
The crawl space in spots has less than 2 ft head room and the house is over 80 yrs old with remnants of the old asbetos steam pipe insulation around. I don't want to spend the whole day in the crawl space.
