    hoar frost plugging exhaust pipe

    Hi,

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

    Thanks.

    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.
