    The safe move...

    The safe move is Uphoner/wirsbo hepex or pex-al-pex .

    The uphoner plates work much better than the "w" plates.

    There are other brands that are similar and are probably widely used.

    Uphoner is the leader and has stood the test of time.

    The pex-al-pex is a grade b. Earlier it was mentioned that I should stick with grade a. Is the grade b stuff then okay to use?

    The hepex is about $179 for 300 ft coil and the Pex al pex I am looking at about $110 per 300 ft coil. Significant price difference if I can go with the al pex. I was reading thought it is hard to get fittings and they are more expensive for al pex? However, I don't believe i would need many fitting b/c it should just be hooking up to a manifold correct? So, can I or should I go with pex al pex?

     I had not realized the Wirsbo Multicor was pex b. I guess they need to do it that way to laminate it.

    The pex a ,b and c are not grades. It is the process used to make it. I am not saying all pex b products are bad. I just have great faith in pex a and wirsbo.

    This expains the process.

    Cold Baseboards

    I have a couple baseboards in my kitchen and one in particular i can find either the inlet or return. I'm not sure. Theres some kind of valve or something i can't identify but after that valve the pipe is cold. On the picture the right of the valve is cold.

    three questions?

    My first question is what's the heat exchanger for?

    My second question is is your floor covered with carpets and furniture?

    My third question is what's the temperature of the floor?

    If your boiler produces sufficient output then your house has to warm up eventually.

    A big advantage of hydronic heating is that it's relatively easy to add terminals where needed. I'd look into adding ceiling radiation. It can make you more comfortable without making your home warmer.
