    hoar frost plugging exhaust pipe

    Hi,

    Does there exist a product that can melt hoar frost from exhaust pipes? Yes, EXHAUST pipes.

    Thanks.

    An exhaust pipe for what?

    A high efficiency furnace.

    In case you want more detail, the pipe only freezes under extremes of temperature and has only done so, I believe, twice, in its several years of life. There might also have been one instance of a child shoving snow into it on purpose... It is very possible that the moronic fools who installed the unit did not do so properly, as I had already caught them on other issues. (one such issue was to actually not attach the exhaust pipe at all...)

    This just feels like a simple problem to solve, though, that might not have to involve bringing back untrustworthy people.

    Have a recommended hvac professional check the whole system if you value your safety.

    The pipe should be insulated if it runs through a space that will get below 32. Consult the installation instructions for details.
