  1. Will this heater connect to a standard BBQ propane cylinder?

    1. yes. That's what Mine is connected to.

      Helpful?

    2. Yes, the fittings hook directly, no adapters or anything else needed.

      Helpful?

    3. Yes. That is what I am currently using.

      Helpful?

    4. Yes it will

      Helpful?

    5. YES, your grill tank will work fine with this unit. I get 8-12 hours use from a tank. this translates to 2-3 weekends in the shop. I have to turn it off after an hour or so because it heats my 400 sq ft shop so fast.

      Helpful?

    6. Yes, most heaters like this use the same tanks as gas grills use.

      Helpful?

    7. Yes it will.

      Helpful?

    8. This Mr. Heater propane heater will need to be connected to at least a 20 pound propane tank.

      Helpful?

  2. How bad are the fumes from this model ?

    I have a 24x24 garage. not insulated. 10' ceiling.

    1. NOT BAD AT ALL IN MY 2 CAR NON-INSULATED GARAGE.

      Helpful?

    2. They recommend keeping a window / door cracked. I have a 3 car garage that I have been using it in, and haven't noticed anything to speak of. I have only kept mine running for 15 minutes at a time, and can't say I have been overwhelmed by any fumes at all.

      Helpful?

    3. My shop is 18x20 and this unit will heat it in about an hour with outside temps as low as 17*. My shop is not insulated so I feel this is a great setup.

      Helpful?

    4. The fumes ar not bad at all, hardly any. You will never want to be around a fuel oil-kerosene fueled heater again after using a propane fuel heater.

      Helpful?

    5. It is advised to use a vapor withdrawal propane supply. If you have any questions on this type of propane, please contact your propane dealer. Being it does use the oxygen from the area it is being used in, the building will need to be well ventilated.

      Helpful?

  3. can this heater be used with a thermostat

    Such as a thermostat being wired in series with the 115 volt power supply?

    1. No, if you cut the AC voltage the blower fan would stop, and possibly the flame, but the flame has to be lit manually by pressing the buttons so it would not re-ignite when the thermostat kicked back on. If the flame did not go out when the AC was cut you'd have a fire risk, as the flame would be concentrated in one spot instead of spread out over the barrel.

      Helpful?

    2. NO.... this unit does not have the auto start feature.
      if you want a thermostat operation you will need to get the heater with autostart.

      Helpful?

    3. This heater cannot be controlled by a thermostat, since the burrner is not adjustable and therefore produces 35,000 btu at a steady rate. The 115 VAC input to the unit provides power to the fan. If the fan were to stop running for any reason, including a power failure, the unit would completely shut down, due to an over-heat protection sensor near 240F. Any effort to try to control the fan would would be doomed to failure. This unit is not designed like a regular furnace, which does use a thermostat, but is intended for use as a manually operated heat source.

      Helpful?

    4. I do not think that would work. The power supply would turn off the spark - but the propain would continue to flow I think...

      Helpful?

    5. This heater is made to run constantly. There is not a thermostat option that will work with this heater. We also offer forced air heaters that are made to be thermostatically controlled. See link below for more details.

      Helpful?

  4. How much propane does this heater use?

    Will a 5 gal propane can, BBQ grill size, last 24 hours, or how long?

    1. you can get 8-12 hours per 20 pound tank (grill tank).
      the prefilled "tank swap" is about 3.2 to 3.5 gallons. Your local gas company will fill to 4 gallons. thus the time difference.

      Helpful?

    2. This is a tricky question. It would depend on a few things . The size of the area you are heating , Is it insulated or not and just how warm you are keeping the area. I have a bigger unit then you are asking about and have used it to heat a garage 24 - 27 ft ( insulated ) over night at about 50 degrees easily.

      Helpful?

    3. A 20 lb grill size propane tank will last about 12 hours on low setting.

      Helpful?

  5. Mr. Heater Portable Propane Forced Air Heater - 35,000 BTU, Model# MH35FA

    can it be used with-out the blower ? or would it just overheat.?

    1. Thank you for your inquiry. It cannot. Without forcing the air from the chamber, the heater would overheat. Also the heater will not light without the fan running.

      Helpful?

    2. This heater is a "forced air" heater meaning it has to have the fan running for it to work at all.

      Helpful?

  6. Is this heater safe for indoor use, such as my garage?

    1. THAT'S EXACTLY WHERE I USE IT. jUST KEEP IT AWAY FROM FLAMMABLES AND ENSURE ADEQUATE VENTILATION. USE COMMON SENSE WHEN USING.

      Helpful?

    2. This heater is designed primarily for use in construction. The heater may be used indoors only if area is well ventilated.

      Helpful?

  7. How many watts does the 120v power source need to provide? Does it just run the fan? I'm considering using an inverter if the power goes out.

    1 answer

    1. The power required to run this heater is 115 Volts, 60 Hertz, 3 Amps, and 360 Watts.

      Helpful?

  8. Besides the heater, what connections, hoses, regulators, or related is required to operate this heater?

    1 answer

    1. This heater includes a 10' hose with regulator. Nothing else is required to connect the heater to your tank. A 20lb. or larger tank is required.

      Helpful?

  9. Can this be used outdoors in the snow? My husband uses tire chains on his small snow plow and needs heat the area when chains come off.

    1 answer

    1. This heater is for indoor use only.

      Helpful?

  10. How loud is this heater? Too loud to use for a party?

    1 answer

    1. The manufacturer does not give a decibel rating on these heaters. They are fairly loud.
