About how much propane would this use per day or per month if it was set at a moderate temperature of about 68 degrees in a 700 foot, well insulated apartment with normal winter temperatures?
By Brennan W. on August 3, 2016
Answer:This unit will use .926 pounds of propane per hour.

Do I need an external gas tank for this heater, or is it attached to the bottom of the unit? How much gas does it contain, and how long does the tank last in terms of hours? How does one refill it?
By Collin C. - NFI Master Hearth Professional on September 30, 2013
Answer:This unit is designed to be fed from an external fuel tank. While a larger fuel tank is preferable, the smallest recommended tank is a 20 pound cylinder, which would fuel this heater for approximately 18 hours before emptying. Typically a fuel tank of this size can be taken to a tank swap out facility, which is usually sponsored at local gas stations and hardware stores.

What is a hydraulic thermostat?
By eFireplaceStore on August 12, 2014
Answer:A hydraulic thermostat uses a vial of fluid to control operation of the heater. Based on the temperature that is set, the fluid will expand to a point that the heater will shut down. Once the room cools again and the fluid begins to contract, the heater will come on again. This expansion and contraction cycle will continue to maintain an even temperature in the room.
By Norman from Nevada and Utah on August 12, 2014
Answer:Hydraulic thermostats use what is known as a "thermally expansible fluid." This is a highly reactive fluid that swells as the heat rises and shrinks as the heat falls. This fluid is contained within a capsule inside the thermostat, and a light metal rod is extended into the capsule. As the fluid rises, the rod is pushed up, which affects the thermostat dial.
This thermally expansive fluid needs to be very tightly contained--if any escapes, it severely compromises the readings of the thermostat. Very tight seals are placed to contain the fluid inside the capsule. The rod is fitted with a spring and lock system precisely made to react with the fluid, but natural fall back down into place as the fluid shrinks.

Is this gas heater UL listed?
By eFireplaceStore on November 3, 2014
Answer:This heater does not carry a UL listing, but is CSA certified to meet Z21.11.2 standards. This is the default standard for unvented room heaters and is accepted in most jurisdictions.

How can I avoid the difficulty starting where the flame dies-out while turning the dial from start to low?
By Kevin E. - Fireplace Specialist on December 19, 2011
Answer:This concern is reminiscent of one we see often when supply pressure to a gas appliance is too low. Using a manometer, confirm that you have a pressure of at least 11" of w.c.being supplied to the unit.

I have an Empire BF 20, but I want to set it on the floor and it did not come with attachable "feet" so that it would sit flat. Where can I purchase some?

What is the difference between blue flame and infrared heaters? Is it their heat output and efficiency?
By eFireplaceStore on December 15, 2014
Answer:Both heaters offers models with the same level of heat output and efficiency, but the designs differ in the way they supply heat to the room. Infrared heaters warm a room by warming the objects (furniture, appliances, people) as opposed to the air. Many customers find that this type of heating is more comfortable, as it does not create a stuffy zone around the heater. However, the heater is limited to the reach of the infrared rays. Blue flame heaters warm the air, as opposed to the objects in the room. They can effectively warm a greater area through circulation, but the space immediately adjacent and in front of the heater can be uncomfortable.

I live in a rental unit that has one of these as the sole heat source. My flame is really yellow and the unit won't stay lit. What do I need to clean?
By Tyler M. - Fireplace Specialist on November 13, 2012
Answer:This issue is commonly caused by a dirty or partially clogged pilot assembly. In order to clean the pilot, the nut that is threaded to the end of the pilot tube will need to be loosened and disconnected from the pilot assembly. The nut is approximately two inches down from the end of the pilot tube. The tube can then be cleaned out with compressed air and the nut re-tightened.

Does this unit come with a blower or do I need to order that separately? If so, how much is the blower and do you carry that item as well?
By Will M. on February 15, 2016
Answer:This will not arrive with a blower, but this optional accessory may be purchased separately and is shown under "Popular Accessories for this Item" on the product page for this item.

I'm considering this space heater for my remote 280 sq.ft. cabin, or the 10,000 BF10 if it is suitable and more efficient - that's very important. The cabin is super-insulated and we have heated it with the kitchen cook stove gas oven, no problem.
So do I understand that this heater, when left alone, has a thermostat control to go on and off to maintain a desired room temperature? Or do you set it and it blows constant heat at that setting? We only need it for six hours per day. Also, is there a space heater you recommend where I could attach the wall thermostat that's already in place, leftover from a broken VT Castings gas heater?
By Collin C. - NFI Master Hearth Professional on November 23, 2012
Answer:Theoretically, the BF10 heater would be right at the capacity for the size of the space and could heat a well insulated area of this size. However, you may choose the BF20, as it would heat the space faster and would not need to run as often.
Both units do have built-in thermostatic controls that would allow you to adjust the unit to a desired temperature. The heater would cycle as necessary. Unfortunately, the valves for these units are fully mechanical and will not allow for use of an external thermostat. This is the case for all of our wall mounted vent-free heaters. Only the larger direct vent furnaces and console heaters have provisions for an external thermostat.

I am heating a space: an 8'x10', 10' mono-pitch roof tiny house, down to 6' of the space. I need a vented heater. Can this heater be vented? And do you have a tiny heater with fewer BTUs? Thank you.
By Brennan W. on October 12, 2016
Answer:We do indeed have a few vented heaters that are very low BTU.
