Overview Of Wall Furnaces

Definition and Function

Wall furnaces, also known as wall heaters, are self-contained, compact heating units permanently mounted in or on the wall of a building. These units vent directly through the wall or roof, eliminating the need for ductwork for distributing warm air or venting combustion gases. This design allows for efficient space use and direct heating of specific areas.

History

The first coal-fired wall furnaces appeared around 1935, designed to minimize costs and conserve floor space. Their popularity surged by the 1950s, as homeowners sought space-saving alternatives to traditional cast iron radiators and full-sized standard furnaces.

• Gas Wall Furnaces: Powered by natural gas, these units are more complex and require professional installation. Operating costs are lower, but their lifespan ranges from 10 to 20 years. Additionally, consider the risk of carbon monoxide leaks due to their dependence on combustion.
• Electric Wall Furnaces: These units use electricity for heating, making installation simpler. While they often have longer lifespans, their operating costs can be higher compared to gas models, especially in areas with elevated electric rates.

Using wall furnaces as an effective heating solution enhances comfort while addressing space limitations in various living arrangements.

Benefits Of Using A Wall Furnace

Wall furnaces provide unique advantages for homeowners seeking efficient and effective heating solutions. Their compact design translates to numerous benefits, particularly in space and energy efficiency.

Space Efficiency

Wall furnaces maximize space with their compact design. Here are some significant points:

• Smaller Profile: Wall furnaces occupy less floor space, making them suitable for smaller homes, individual rooms, and accessory dwelling units (ADUs). Their smaller dimensions allow for flexible placement in tricky areas of the home.
• No Ductwork: The absence of ductwork simplifies installation processes and permits wall furnaces in locations where traditional heating systems may not fit. This flexibility means you can heat areas like basements or attics without major renovations.

Energy Efficiency

Wall furnaces excel in energy efficiency, providing effective heating:

• Lower Energy Consumption: Wall furnaces often use less energy than central heating systems since they directly heat individual spaces. This targeted heating reduces overall energy usage in your home.
• Responsive Heating: Wall furnaces heat up quickly, delivering warmth precisely where needed. This efficiency allows for reduced energy bills, particularly during peak heating periods.
• Programmable Settings: Many wall furnace models include programmable thermostats, allowing you to adjust temperatures according to your schedule. This feature enhances energy savings by minimizing heating when you’re not home.

Types Of Wall Furnaces

Wall furnaces come in various types, each offering unique features and benefits. Understanding these types helps ensure you choose the right option for your heating needs.

Electric Wall Furnaces

• Electric wall furnaces use an electric heating element to warm the air, which circulates into the room.
• Electric models operate quietly, require minimal maintenance, and generally last longer, with a lifespan averaging 20-30 years.
• They eliminate risks associated with gas, such as leaks and carbon monoxide poisoning.

Gas Wall Furnaces

• Gas wall furnaces utilize fuel, like natural gas or propane, to generate heat.
• Professional installation is necessary due to complexity and safety hazards, including potential gas leaks and carbon monoxide risks.
• Although initial costs are higher, gas wall furnaces can be more economical to operate long-term, offering a lifespan of 10-20 years.

Direct Vent Wall Furnaces

• Direct vent wall furnaces draw air from outside for combustion and expel exhaust gases outside.
• This design improves safety, as it minimizes indoor air pollution and eliminates the risk of carbon monoxide leaks.
• Direct vent models can be installed in various locations without needing a traditional chimney.

• Ventless wall furnaces operate without exhaust vents, using indoor air for combustion.
• These heaters are easier to install since they require no ductwork or venting, making them suitable for homes with limited space.
• Regular maintenance is crucial to ensure safe operation, as improper use can pose health risks due to insufficient airflow.

Installation And Maintenance

Installing and maintaining a wall furnace involves specific steps to ensure efficient operation and safety. Follow the outlined processes for successful installation and upkeep.

Installation Process

Before starting the installation, turn off the power to the area to prevent electric shocks. Switch off the breaker or fuse box.

Choose the installation location carefully. Avoid areas behind doors or draperies, and ensure adequate clearance from combustible materials. For gas-powered wall furnaces, maintain minimum clearances: 2.5 inches from the floor, 16 inches from the ceiling, and 4 inches from side walls.

Locate and mark the wall. Install the furnace between 2x4 inch wall studs spaced on 16-inch centers. Mark the outline of the furnace along the edge of a stud for better support.

Inspect the wall, floor, attic, and roof areas. Ensure no pipes, wiring, or other obstacles could interfere with the installation.

Maintenance Tips

Inspect your wall furnace regularly for any signs of wear or damage. Check filters monthly and replace or clean them as needed to ensure efficient airflow.

Schedule professional maintenance annually. A qualified technician should clean internal components and check gas connections to ensure safe operation.

Monitor the furnace’s performance frequently. If you notice unusual noises, weak airflow, or inconsistent heating, contact a professional for an evaluation.

Test the thermostat regularly for accuracy. Adjust it according to your heating preferences and ensure it responds appropriately.

Ensure proper ventilation. For gas-powered units, check venting systems for blockages and clean them as required to prevent safety hazards.

Common Issues And Solutions

Power And Electrical Issues

• Tripped Breaker Or Blown Fuse: Check the circuit breaker or fuse box. The breaker might trip, or a fuse could blow. Reset the breaker or replace the fuse when necessary.
• Loose Wiring Connections: Inspect the unit’s wiring for loose connections. Turn off the power to the heater, disconnect it from the wall, and tighten any loose wires.

• Gas Valve: Verify that the gas valve is in the open position. When the valve is perpendicular to the gas pipe, turn it parallel to allow gas flow.
• Pilot Light: Confirm the pilot light is lit. If it’s out, consult the owner’s manual to relight it. If the pilot won’t stay lit, clear the pilot tube with compressed air or replace the thermocouple.
• Gas Line Blockages: Ensure the gas line is free from blockages. Inspect the line for any obstructions that may impede gas flow.

Conclusion

Choosing a wall furnace can be a smart move for your home heating needs. Their compact design and energy efficiency make them ideal for smaller spaces where central heating isn't an option. With different types available you can find a model that fits your budget and requirements.

Proper installation and maintenance are key to maximizing performance and safety. By understanding the specific needs of your space and the features of various wall furnaces you can make an informed decision that enhances comfort while potentially lowering energy costs. Embracing this heating solution can lead to a cozy and efficient living environment tailored to your lifestyle.
