Problems with driveway heating system

Our contractor installed a heat system in our driveway. I’ve read comments here regarding them. It looks like they have a boiler. I’m assuming that’s what we have. I went down to check it Yesterday and the system wasn’t running. our slab temp showed 31° in our tube showed 63°. They sent a plumber out. He spent four hours working on it and got it running in the four output tubes were hot about 3 AM. I heard it making a weird noise I went down, and only two of the output tubes were hot. This morning I wake up and only half the driveway is still clear as we are getting snow now now only one tube is hot the other ones getting cold. I see here where they talk about antifreeze in the line. I don’t know if they did that. How do I find someone who knows what they’re doing to work on the system. I feel that the plumber they hired doesn’t know anything about it and it’s just flying by the seat of his pants and we spent over 10 grand for this brand.

    It could be as simple as an airlock in some of the tubes. They will need a transfer pump to push enough fluid around the loops to purge them properly 

    the freeze protection rate of the glycol nerds to be checked also

    Do you have any paperwork indicating a design was done?

    Most often the problems are in the piping. You need to provide much more information on your sys before a definitive conclusion can be reached. Pics of your whole sys from the boiler to the distribution circuits, to tube layout. So, get hopping. The great guys on this site are chomping at the bit to help you solve your issues.
