    Radiantec

    Radiantec is infamous on The Wall. Do a Wall search for "radiantec" and display 200 results. There has been a ton of discussion about them.

    I have not had any direct dealing with them or their 7/8" tube, but their design methods and materials are absolutely the least expensive possible.

    Radiantec

    If they are still using that 7/8" PE tubing, I would take a moment before considering to go that way. That size tubing has a very large bend radius which can be very unforgiving. With a large bend radius, don't expect to install tubing much tighter than about 16" on center. If you kink that pipe, which is highly likely, you will need to cut it and install a barbed connector to rejoin it. This is Alzheimer tubing, no memory at all. And while I mention barbed connectors, that is how you will be terminating it on a relatively crude manifold set. To get a good fit, warm the pipe enough to make it slightly pliable. Warm it too much and the pipe will collapse.

    By the way, while you're figuring out all the money that you or the homeowner is saving, don't forget to add the cost of all non-ferrous components, no steel or cast iron boilers or circulators or a SS flat plate heat exchanger since you will be installing tubing without the properties of an O2 barrier.

    After doing a few of these systems I came to the conclusion that the only one making money is Radiantec. The installation time is significantly longer, perhaps by a factor of 2x and in the end what you have is a half **** system.
