Gravity Wall Furnaces
The Gravity Wall Furnace offers total comfort for a fraction of the cost of electric heat. The furnace’s common size retrofits easily. Designed for installation in a standard 2 x 4 stud wall cavity. Optional Out-of-Wall Kit (GWTW2W) allows surface mounting and encloses the sides.
The 50,000 Btu GWT50W installs in the wall between adjoining rooms and heats both.
For the smaller GWT25W and GWT35W, an optional Rear Register Kit (GWTR1W) directs heat to an adjoining room.
Our economical Gravity Vented Furnaces utilize state-of-the-art technology for better fuel efficiency. Recesses into a wall or surface mounts with the optional kit.
- State-of-the-Art Technology for Better Fuel Efficiency
- Thermostat not included
- Common Size Retrofits Easily
- GWT25W/35W Furnace Recesses into Wall or Mounts Flush with Optional GWTW2
- Total Comfort for a Fraction of the Cost of Electric Heat
- Optional Blower Available
Vented Counterflow Wall Furnaces
Counterflow wall furnaces circulate warmth at floor level to provide comfort at a fraction of the cost of electric heat. The front panels remove easily for cleaning and servicing. Available in standing pilot with matchless piezo ignition or state-of-the-art electronic ignition.

Venting Methods
All of Empire’s Zone Heating appliances allow you to efficiently warm the rooms you use most. Zone heating saves energy and money by letting you turn down the thermostat on your central furnace.
Empire offers zone heating systems in Direct-Vent, Vent-Free, B-Vent and Power-Vent. Each has its own advantages. Your dealer can recommend the system that’s right for your home.
Direct-Vent
Direct-Vent system uses two vent pipes. One draws air in from outdoors to support combustion. The other exhausts the by-products of combustion to the outside. The two vent pipes may be concentric (exhaust pipe within a larger diameter intake pipe) or co-linear (separate pipes of about the same size).
Combustion takes place inside a sealed chamber – with a glass front in the case of a fireplace. Room air circulates around the combustion chamber, often assisted by a blower, to heat the room.
A DV system is often installed along an outside wall to simplify the vent run, but can also be installed elsewhere in the home and vented through the roof.
Advantages:
- Good efficiency – 60 to 80%
- Good heat output with thermal transfer through the glass and air circulation
- Separates room air from combustion air
- May be used as primary heat source
- Can operate with a remote or thermostat
- Most systems can provide live-saving heat during a winter power outage
- Choose fireplace, insert, cast iron stove, or heater
Vent-Free
A Vent-Free system uses room air for combustion and delivers 99.9% of the available heat energy directly to the room. VF systems have an unmatched safety record, thanks in part to their clean-burning technology and their Oxygen Depletion Sensor, which instantly shuts of the valve if oxygen in the room drops to and unsafe level. Because no venting is required, VF systems offer more installation options.
VF systems are limited to 40,000 Btu and must be operated as supplemental heating sources in conjunction with a central furnace that circulates air.
Advantages:
- Unmatched efficiency – 99.9%
- Offers the most installation versatility
- Usually less expensive to buy and to install
- Can operate with a remote or thermostat
- Most systems can provide live-saving heat during a winter power outage
- Choose fireplace, insert, heater, cast iron stove, burner and log set, or contemporary burner
B-Vent
A B-Vent system takes in room air to support combustion and exhausts combustion by-products (along with much of the heat) to the outdoors through a single vent pipe – usually through the roof or through a chimney.
Because they are relatively inefficient, compared to a DV or VF system, most B-Vent fireplaces are rated as decorative appliances. They provide the ambiance of a fireplace without overheating your rooms.
Advantages:
- Ideal for replacing a wood stove or oil burner – eliminates handling solid fuel
- Can operate with a simple remote (no thermostat)
- Usually less expensive to buy and to install
- Choose fireplace, heater, or burner and log set
Power-Vent
Power-vented systems – such as Empire’s US90-Plus wall furnace – offer unmatched efficiency, exceeding 90 percent AFUE. They are so efficient at extracting heat, very little heat energy exits via the flue. This means they can be vented with low-cost PVC venting instead of costlier stainless steel.
Advantages:
- Unmatched efficiency in a vented system – greater than 90%
- Unmatched heat output
- Separates room air from combustion air
- Can also provide humidity to offset dry winter air (US90 requires accessory tray)
- May be used as primary heat source (however, they do not operate in a power outage)
- Can operate with a remote or thermostat
- Choose fireplace, insert, or heater
