Questions & Answers

Can this unit be installed in a double doors car garage?
ByDec 21, 2025
1 Answer | 
Answer This Question

No, vent-free gas appliances should generally not be installed in a car garage due to safety and performance concerns. Garages often contain flammable materials and can have poor ventilation, posing significant hazards for unvented heaters

      Is a 20lb propane cylinder good for this unit
      ByOct 21, 2025
      1 Answer | 
      Answer This Question

      Yes, a 20-lb propane cylinder can work for your Rinnai vent-free heater, especially if it’s used for supplemental heating or in a space where the heater doesn’t run at full capacity all the time. However, if the heater will be running at/near full capacity (22,000 BTU/hr) for extended periods, or if you want fewer tank‐changes, you may want to consider a larger LP tank a stationary 120-gal tank for best results.

        while understanding this is not intended as a primary source of heat. If I use this product as a heat source in a 420sq ft tiny home. would it be better to use a vented or unvented unit? will a unvented unit produce unsafe levels of CO in that size area?
        ByOct 10, 2025
        1 Answer | 
        Answer This Question

        Hi Zack, for a 420 sq ft tiny home, a vented (direct-vent) gas appliance is the safer choice if you plan to use it as a primary heat source

          Can the Rinnai propane 10,000 BTU be mounted on the wall?
          BySep 3, 2025
          1 Answer | 
          Answer This Question

          Hi Alice, these are not designed to be mounted on the wall, but as floor models.

            Can this unit be hooked up directly to an outside to inside propane source by a professional?
            ByMay 15, 2025
            1 Answer | 
            Answer This Question

            Yes, an outside propane tank can feed the EX11, but it must be done by a licensed professional using the correct regulators, piping, and shutoffs—and fully tested and inspected to meet code and ensure safe operation.

                Can this be used in a large guest bedroom for occasional use?
                ByDec 20, 2024
                1 Answer | 
                Answer This Question

                Hi Jinmaine,If the room is well-ventilated, within the size limit, and used occasionally, a 10,000 BTU Vent-Free Propane Gas Heater can be an efficient choice. For larger rooms or regular use, you may want to consider a higher BTU model or a vented option for better long-term safety and performance. Please check local codes as well to confirm, as in some area vent free are not recommended in bedrooms.

                  Great little heater
                  I installed this heater in a spare room we have its about 300 SF. Set the heater at 60 on Eco mode and it keeps the room between 62-54. It has worked perfect for what we need.
