    Freezing –Help!

    Hi everybody,

    Searching over the net I found this forum and I hope somebody will help me.
    I had a problem with my furnace last year. It’s a hydronic system and the heating-coil start leaking so I had to replace it. Unfortunately the manufacturer it’s in Quebec (Thermoplus Air Inc. - www.thermoplus.com) and the system it’s “old” no spare parts on shelf – that’s what they said, so I found something similar here (Toronto) but a different size (H, W, L) but with higher BTU. I had a professional who did the redesign in terms of piping and fitting into the body who told me it’s gonna work for sure – but it’s not the case.
    Now, with the new coil is something very strange: top of the coil is hot, and bottom is barely warm. I must say that the coil is placed horizontal (inlet top, outlet bottom) and
    the principle is relative simple: hot water from the boiler tank goes into the heating coil and is re-circulating using a Grundfos pump back into the boiler. A blower is placed underneath the coil and blows air towards the fins (passing thru is heated up) and goes into the vents.
    I thought initially that is air left in the system and the water is not moving, but that’s not the case.
    Then I checked the pump, but the pump is working.
    Now, if I turn off the blower (for the air) the whole coil gets hot (top and bottom) the pump is working and the water is re circulated. As soon as I turn on the blower the bottom of the coil gets barely warm in a short period of time.
    Anybody has any suggestions? Do I need a new pump with a higher flow rate?

    Thanks in advance,
    Radu

    What he said.
    Those who restrain desire do so because theirs is weak enough to be restrained. (William Blake)

    Sounds like you called the wrong Pro. We can't and choose not to help as this is how we make a living. Read the rules!

    I thought that was a BS thread to get Robo, Carnak and Made to start fighting again like the old days.

    Is that thing still broke? WTF??!!
    If you can't learn to do something well, learn to enjoy doing it poorly.
