    Re: Glycol pipes.

    A little explanation of what the pipes are serving might help things along a bit.

    My first thought with the limited info would be to run the pipes around the outside of the cold store.

    Normally the glycol is used to form a thermal barrier between the Cold Chamber/s and the Ground they are sat on! ( I presume this is the dilemma?)

    Sorry balnauld! Personally I don't know of a way around digging them up to repair them.

    Re: Glycol pipes.

    I agree. You will not stop the pipes from leaking without digging up the floor. If you just valve off the leaking circuits you will be digging it up later anyway due to the heaving floor from the perma frost that Grizzly mentioned. Normally they don't just start leaking if the proper material was used. Has something changed or did something happen? I had a customer that had the glycol pump fail and decided to put it off for budget reasons. The pipes froze and burst. Not good!

    Re: Glycol pipes.

    That is am interesting statement. Why do you say it is safer? Why is Glycol underfloor heat dangerous?

    not to say that glycol is dangerous just that with an electrical system the heater is made of a stainless steel wire therfore not much to go wrong ie damage leeks etc
