Propane Tank Heater?

Discussion in 'Growroom Design & Setup' started by Funkadelic, Sep 14, 2018.

  1. Hey Farmpham,

    I'm growing in a garage and winter is coming up. We see snow/ice, though I'm not in Michigan (brrrrr).

    Lights keep the room hot enough but during dark cycle (daytime hours), temps obviously drop a lot .
    Rather than run electric heaters, was thinking maybe a propane heater since it will run when I'm not in there . I know the extra co2 is better for lights on cycle. So I'm here asking and brainstorming . Advice?

    I use a propane heater in winter months. Works great. I found one that has a thermostat on it. I love it!!

  3. Awesome! I figured I wasn't too off base. I just don't want to jack up my electricity for winter heating. I have a couple of heaters in there but I would rather use gas as my first line of defense .

    What unit do you use? Thanks for the help. Big time .

  4. I have been using Colman camp stoves for years, two burners. Cheap and good.

    Be careful man, carbon monoxide is a killer!!
     
  7. Thank you guys. Been looking at these. Hoping to find one with a thermostat ... lights on temps are no problem . I just need to keep that 15°F + swing in check to prevent powdery mildew, etc. Cannabis doesn't like 40 degree weather

    Carbon monoxide kills. Do not use those heaters in any enclosed space that is attached to a dwelling. Add a carbon monoxide detector to the room is using and if that sucker beeps , shut it down, air it out.
    I use them in an outdoor greenhouse, the plants love the extra co2.

  9. They don't put out Carbon Monoxide, They put out CO2 What is why there Vent Free ?

  10. The Mr Heater units have an O2 sensor ... evidently if the oxygen count gets too low, it's an auto shutoff. My garage is unattached, and I use irrigation so my contact with the flower room (where I need a heater) won't be much.

    An older grow I ran had a co2 burner and we got our PPMs really high. I tried not to stay in that room long .

    GOOD heads up guys - safety is super important with gas .

    I have a buddy who is an HVAC professional and I will have him double check everything too.

    I think Mr Heater units require 100lb tanks ... so I will probably hire a propane company to bring it out and do my refills I'm thinking .

    LOVE the idea of added co2 as a bonus with lower (electric) heat bills. I have a couple of electric heaters on controllers with thermostats to help fine tune temps but I figure gas can keep it from being 25°F at least ....

  11. From what I remember..if it combusts..there is CO2 produced..but my memory ain't so good anymore..LOL

  12. Hey bro does it need a 100lb tank? Any idea if a tank could split the gas line and feed 2 units on different levels of a garage?

    Yes, but I would hard line it. Bigger the tank the better.

    Absolutely NO! This unit is designed for a room. It’s a radiant propane heater.

    I do not grow in tents in general. I do have a 20x20 that I’ve veged in. But in general I flower in rooms or garage. CC2C4FBC-2680-4758-8BDB-BB17A9E87853.jpeg
     
  17. More info please.

    Okay now want 2 floors of garage gas heated. Could I use the same tank and a T?
    I have an HVAC buddy who will probably set it up.

    Have perfect spot for large tank to feed both floors.

    Doable?
     
  18. * specific heater TBD depending on setup specifics

    Just put in a furnace, go 95.5%, duct it in, add a carbon filter to the return, heck add a coil and condenser for those summer months, ask him to pick up 25% make up air from outside with a variable damper that you can close is it’s freezing outside. I usually do a system like that for around $4k for heater and duct, add ac 14seer for about additional $8k. All can be propane or natural gas, or even electric heat pump, more for that.
    But it’s the best route. Or look up hot dawg heaters , cheap and I use them in my green houses . 93% eff, and stand alone systems, nat or lp.~$800-1200)$.

  20. I'm sadly on a shoestring. Good lord I wish the quantum flux capacitor in my time machine worked.

    2 zone heating minisplit would have solved all this. A 3 ton 1 zone only AC no heat pump really isn't the total solution I neex .

    I will keep looking at cheap gas room heaters with thermostats preferably .

    Also realized the dehueys will run a lot in winter dark cycles and they crank a lot of hear too .

    I don't mind flowering at low temps either as long as I can keep the VPD in the right area . If that makes sense .
    And added co2 in the air is zero danger since it's a garage with exhaust in the flower room on the light switch at the entrance . so thats good.

    Luckily gas heating is mostly needed Maybe 4 months?

    Maybe run off a co2 grow controller?
