Radiant Tube Heater

radiant tube he has. Make sure the correct orifice is in it for propane. Make sure the reflectors are with it that go over the top of the tube and then make sure gas pressure is correct. All mfr are different, I use to install a fair amount of the Vantage tube heaters and we have worked on just about all units out there and still do. Pretty simple machines once you have the correct info. Could also be sooted up in tube, something to look for. Tim

    A friend of mine

    has a detached garage where he works on his collectible motorcycles. He bought a ceiling hung propane radiant tube heater for his garage on E-bay and installed it himself. It runs but doesnt heat like it should. He called and asked me if it's supposed to have an orifice at the end of the tube to slow the flu gases from exiting too fast. I have no idea. I've seen them but never worked on them. Does anyone out in the collective knowlegde of the Wall know anything about them. WW

    What brand?

    What brand tube heater is it Wayne? Most of my experience is with Co-Ray-Vac. These tube heaters actually run in a vacuum and they have an adjustable orifice in one end to set the proper vacuum in inches water column. I really like these types because if (when) the tubes rust out and develop leaks they draw extra air into them rather than leak flue gas out into the conditioned space.

    As suggested above, get a manual for the type of heater he has (maybe available online?) and start checking settings. Clean reflectors are very important with a system like this too. Even a light layer of dust from sitting around before or after installadion will change the performance dramatically. If he's trying to run this type heater with out reflectors, faaa-get-a-boud-ittt! :)

    If it was on LP before....

    and its being used on NG now, it has a wrong size orifice on the OTHER end...

    Will still produce some heat, but not the proper amount.
