We are building a sunroom partially over a heated crawl space and partially on footings. We want to keep the hot water heating pipes as insulalted as possible by coming up through the heated crawl space with both the feed and return. Are there radiators made that allow you to connect both pipes at the same end of the baseboard unit? Are there units sold that would allow PEX to be looped back through the enclosure and brough back to the feed end? Thanks.
I am no heating man but the ones I seen hace a connection at each end, bring them both up at one end and run the pipe in the radiator to other end, you are using that peck pipe it is small enough to do that, let me know.
