Hi All,
I have been using a portable Propex HS2000 to heat two RTTs for about a year now. This is my first winter with it. This spring and summer, I've simply run the supplied hot-air duct into the tent (through a zippered opening) and let the heater draw return air from the outside... and it has been good enough.
Winter is different. When the unit fires up and shuts down, it operates the fan for a few minutes before and after supplying heat for safety. Since I do not have a return-air running between the heater and tent, it is pumping -25º air into the tent while cycling. That's bad. I should have thought of this and didn't.
I need to come up with a solution for both return and supply air for the Propex and the units arrive with a shrimpy little bit of 60 mm hose. There are a lot of options for 60 mm duct on the Interwebs, but not a lot of specs from Propex nor ideas in general.
I'm wondering:
Input would be awesome. I can't be the first guy to check into this stuff. Thanks.

I'm wondering:
- What max temperature rating do I need to plan for (when the hot air leaves the Propex)?
- Does anyone know if a cost-effective option exists for an industrial-like 60 mm high-temp hose with integral insulation?
- Is anyone aware of some sort of boot or fitting that I could permanently install in the soft part of an RTT to attach the hose to (to avoid running hoses through zippered doors)? Twist-lock or rubber friction type fittings would be awesome.
- Please keep in mind that my hoses will be outside. The heater is protected in an enclosure and I would like to have some sort of ducting that can get wet and isn't required to be dried (like the hose that ships with it).
