    What is the difference between the blue flame and standard infrared vent free propane heaters?
    1 Answer
    The blue flame heaters will heat the air in the room, while the infrared units use infrared waves of heat to heat people and objects in the room.

    from Prescott, AZ asked:
    January 16, 2018
    I'm trying to understand the difference between manual control and T-stat controls. Is it simply control on the unit vs. wall T-stat or is there a difference in temperature control vs. hi-med-low settings? Also, can you help me understand where the gas line comes into the unit and placement relative to shut off valve? Is the optional fan hard wired or a plug and if plug where does it come out of the unit and length of cord? Additional pictures would be great.
    1 Answer
    The manual unit will just have a 3 setting heat control knob, while the thermostatic will have a built in hydraulic thermostat. A remote cannot be added to either one. The gas inlet for this unit, per the manual, is on the bottom left. Unfortunately, the photos and manual images on our page are the only ones supplied by the manufacturer. The blower is an additional option which would be mounted to the underside of the unit, the cord will be no longer than 24" but I would have to double check on exact length.

    will this infrared vent-free heater produce less moisture buildup than other non-vented propane heaters?
    1 Answer
    It will indeed. Other blue flame heaters put more water vapor into the air during combustion than infrared heaters.

    How can I determine the model number of my Empire gas wall heater?

    from MI asked:
    October 4, 2017
    What size LP tank will I need to operate this product?
    1 Answer
    The size of the LP tank will be determined by the tank location and the tank location will be determined by both local and national code requirements, which is why this recommendation should really only be made by a licensed plumber or gas fitter. However, most hearth manufacturers will recommend a minimum tank size of 100 lbs., or so, but you could likely get away with using a smaller, 50 lb tank with this particular heater and not experience any outages.

    from Massachsetts asked:
    November 21, 2016
    Can this be operated from a 20 lb tank?
    1 Answer
    No indoor hearth systems should be operated with a 20 lb. tank as this tank size and the requirement that it must be installed outdoors will cause outage issues with the heater.

    from Gray, Maine asked:
    November 15, 2016
    We would like this heater for a back up in Maine. If we are away and the electricity goes out we want to be able to set the heater to heat the house. Will we be able to set the temperature control and be 100% sure this will keep our basement with water heater, furnace, etc warm enough?
    1 Answer
    No ventless heater should be left unattended for any extended length of time. Additionally, no ventless heater should be in operation any longer than 3 hours at a time. Also, this is a manually controlled heater and would provide no thermostatic control. There is a thermostatic version available here, but it should not be left unattended as a backup heat source in the event of power failure.

    What is the altitude rating for this Empire SR18 infrared vent-free gas heater with manual controls?
    1 Answer
    Like all vent free appliances, it can be installed at elevations up to 4500 ft. Above this, the air is too thin for any vent free appliance to operate without issues arising from a lack of oxygen.

    August 26, 2015
    Does this wall unit have its own gas pressure regulator that reduces the pressure down so it can be used as designed?
    1 Answer
    The heater does indeed have an inlet regulator that will aid in regulating gas pressure. Inlet pressure coming to the heater must be between 11 and 13 inches of water column.

    How much odor can I expect from the gas?
    1 Answer
    Vent free appliances should operate without excessive odors. However, there will inevitably be some odor associated with the burning unit. The amount of odor is purely subjective. A large quantity of customers notice no real odor at all, while others are sensitive to such smells and find them bothersome.

    from Washington, NC asked:
    December 24, 2013
    How does the manual control work?
    1 Answer
    The manual control knob can be turned to one of three heat settings, allowing one, two, or all three burner plaques to light. The system is totally manual, so the knob will need to be turned down, if you require less heat. Output on the first setting is 6,700 BTUs. The second setting yields 12,000 BTUs. The third setting offers the full output of 18,000 BTUs.

    Can this heater be used at 8,600 feet?
    1 Answer
    This unit, along with our larger capacity models, can be used at high altitude without a problem. They will however, suffer a 6% loss in heating capacity per 1,000 feet of altitude past 4,500 feet. You may want to switch to a slightly larger unit if this will affect total heating capacity enough to make the current model inadequate.

    The Right Heater for The Job
    Needed to heat my pottery studio in Maine. The website had good and accurate info. When I called with questions, the person I spoke with was willing and very able to answer them all. He helped me make the right choice. It arrived exactly when they said it would. It's doing a great job. I've been comfortably making pots, even though it's still snowing outside.

    This is the latest one of many Empires I've purchased over the years for use in RVs and homes. I've never been disappointed with the performance or the even heat they provide. I've used several in high elevations without a glitch. I've recommended this heater to several friends and they're always as pleased as I have been with them. Great product!

    None Better
    If this company's quality control stays on target then you will not find a better heating, longer lasting wall heater. I've heated my whole house "1700 sq. ft." exclusively. Built in the 70's as an all electric home, in weather to 10 below with a wind chill even lower. I use no other heat source, just one thermostat controlled 30,000 btu wall unit, placed in the middle of the house on an outside wall. I've done this for over 20 year, only having to replace the unit once in that time. This unit will last well past it's warranty time. I'm so confident in these units that I have bought a spare that I keep in storage. For as I've said: it is my only heat. Buy one, you'll not regret it...

    Next day shipment was amazing
    Ordering and Shipping: I ordered the SR10T unit at this store after trying to find it locally because of concerns of damage in shipment. In the end, I ordered on-line because of the competitive price and free shipping. I accepted the normal shipping terms at check-out and much to my surprise the unit was delivered the next day! Installation: I contracted with a local installer to run the pipes and install the unit on the wall in my basement. They were able to do all of this in about 2 hours time. (it was a very short run to connect to the natural gas source) It only took 20-30 minutes to actually hang the heater on the wall with the 4 "drywall" bolts. Experience after 2 months of actual use: We are heating about 200 square feet in our finished basement room. Sometimes we open up a second room which adds about 50 more square feet. The SR10T is more than adequate for the space we're using it for. We are very pleased with the unit so far and feel secure that we have a secondary heating source should we loose electric power.
    Pros1. Unit is constructed from quality materials and is small enough that it doesn't detract too much from the room decor. 2. Simple to operate. (Pilot mode, Off mode, 1-5 temperature range setting) 3. Easy wall mounting installation. 4. Reliable secondary heat source in the event that first heat source is not available(power outage, etc...)
    ConsThis is not a big deal but it is necessary to hold the Pilot knob down for 60 seconds when first starting up the unit. It would be nice it one could simply hold the Pilot knob down, press the "lighter" button and then immediately set the desired temperature range(1-5). (not a big deal, but a "nice-to-have")

    Finally warm
    I am in a two bedroom 1320 sq ft SW Va . The heater is downstairs and even on lowest setting the upstairs is warm. Got it for emergencies but found it is awesome for everyday use. Heat pump just doesn't do it. I recommend Empire because it is made in the USA. Before bringing a gas heater into my home I searched for what I believe to be the safest I chose Empire. As you can see my Chihuahua enjoys the heater as well. I ordered this heater on a Sunday evening and it was at my door he next evening. I purchased from this seller due to price and shipping. Wow awesome choice!
    ProsMade in USA Warranty Quiet. Heated the room without the noise of a fan
    ConsI didn't buy sooner
