Hello, I am in the process of completely renovating my home. Recently I had to tear up part of the floor to replace a beam that had been damaged by a fire that happened before I bought the house.. I decided that this would also be the best time to clean out the crawl space (mission complete). Now, I am contemplating installing Hydronic Radiant Floor Heating to the under side of the wood floor from the crawl space. However, I am not liking the prices I'm finding for the system installation. Does anybody know if its possible to do this project yourself? It seems to me that all you'll need is the tubing, a mounting device for the under side of the floor, a pump of some sort, and a hot water tank.. I'm sure its more complex then that but that's why I came here. Also, every time I search this topic online most all I find is companys wanting to sell me their diy kit. Are any of these company's legit that you know of? Thank you all!
