A wall furnace can typically be found in properties where the average temperature throughout the year is very cold. Unlike temporary heating systems such as electric and kerosene heaters, wall furnaces remain permanent once installed. As the name suggests this type of heating system is fixed in a contained space within a wall accompanied with vents as a front. These air vents allow heat to be provided directly into the room where the furnace is located so that a warm comfortable temperature can be felt.
There are two types of wall mount furnace – one that is fuelled by gas and another that is powered solely by electricity. Gas wall furnaces produce warmth in the home by using a heat exchanger to heat the air. They generally have a single blower fan that sucks in air through one vent and passes it out through another vent once it has gone through the heating system. Some furnaces grab the air in through a top vent and out through a vent down below whilst some operate in the opposite direction. In gas furnaces, hot gas from the burners heats the air supply pulled into the system, releasing warm air back out into the room. The burnt gas is then released externally from the home through a small chimney to ensure no wastage is left lingering from the burnt fuel.
An electric wall furnace is significantly different to the gas alternative. This is because electric wall furnaces function using electric coils which heat the air blown directly on to them. An electric coil is a special material that resists the electrical current of a device. Once electricity flows through them they become very hot, which is what enables the air to be warm when in contact with the coils. Electric wall furnaces can be seen as much easier to install because they do not need a chimney or gas piping to operate. There is not much of a difference economically-speaking with these two types of furnace. Gas operated wall furnaces cost almost the same as electric furnaces. However, there are specific models that have lower costs than others.
From a safety perspective a propane wall mounted furnace is sometimes considered to be the better option to choose. This is because it does not emit carbon monoxide if the burning of the fuel is properly controlled lowering the possibility of furnace problems. In this scenario, it produces water and carbon dioxide instead. Propane wall furnaces also produce a lot of energy sufficient enough to heat up a whole apartment or a small home.
If you would like to purchase a wall heater you should consider which type of system would best suit your home. A good tip is knowing that gas powered furnaces are generally better installed in small and medium sized homes when also positioned in a central location. Finding out extra information from manufactures and suppliers is a good way to acquire wall heaters with an excellent consumption rate. Furthermore, deals that come with a warranty should be prioritized in the event that a furnace repair is required.
When considering gas wall heaters it is recommended to select one that will meet your needs. The size of the area that requires heating should also be determined to begin with, whether it is a large room or a smaller space. The size of gas wall furnace needed will ultimately be determined by how large the area requiring heat is or will be. Be sure to install the furnace using the instructions provided in the manual. As a general rule of thumb, the necessary space should be kept between the furnace and the wall. Once this room has been accounted for the furnace can be installed by attaching it to a metal plate on the wall. When firmly attached to the wall and the furnace this metal plate will ensure that the installation is well fixed.
The installation should be on the inside of an exterior wall, and it is a must that the vent cap is flush to this exterior wall. The furnace can then be mounted between the studs. You should also make sure that the cut through the wall for the installation of the vent for the gas heater is level. This is to prevent any rain or moisture channeling into the hole and down into the furnace and possibly causing the furnace to corrode. The gas pipe connections must be done by a professional. Gas technicians can be found in the phone book or a smarter way is to obtain references from neighbors or building supply stores.
Lighting The Furnace
Similar to larger furnaces, wall furnaces function using a pilot light to ignite the supply of gas and generate heat. The first time the wall furnace is used, and in the even that the flame diminishes, the pilot light will be lit manually. This task is straightforward for most wall furnaces as it requires only matches. The furnace thermostat should then be set to the lowest setting. Depending on the model or brand, the thermostat may be located on the wall or directly on the furnace itself. If the furnace has an electrical connection this must be shut off using either the switch on the furnace or by flipping the circuit breaker to the room. The front panel of the furnace can then be removed by sliding it up and lifting it off. Ensure that the gas control knob is sitting in the ‘Off’ position. To turn the knob, you normally have to press it in first and then turn it.
At this point the furnace should be left for a minimum of ten minutes to allow any residual gas to clear out and to make sure that the furnace parts are cool. Once this has been done the pilot light access cover can be removed to reveal the pilot light port. The cover can normally be located on the bottom of the furnace by the burners or combustion chamber. Now press in and turn the gas control knob to the ‘Pilot’ setting. While holding the gas control knob in this state light the pilot with the match. Alternatively, if your furnace has a pilot ignition button, press the button to spark the pilot. If on the other hand the furnace has no button, a lit match should be held over the pilot light port for a few seconds until it lights. The gas control knob should be held in for a minimum of one minute. After this time the knob can be released and the pilot will remain lit. The pilot access cover should then be replaced and the gas control knob turned to the ‘On’ position. Then replace the front panel, turn the electricity supply back on and set the wall furnace thermostat to the preferred temperature.
