Wall Units (Heat) Explained: A Comprehensive Guide for HVAC Professionals

As HVAC professionals, understanding the various heating systems is crucial for providing efficient and effective solutions for clients. Among the many options available, wall units—either electric or gas—play a significant role in residential and commercial heating. In this blog, we're diving deeper into the two major types of wall units, their construction, and operational mechanics.

What are Wall Units?

Wall units are heating fixtures that typically incorporate electrical wiring embedded in glass or ceramic tile, allowing for the efficient radiating of heat into a space. They are designed to be recessed deep enough into the wall to enclose resistance coils, and often feature built-in fans to distribute heat throughout the room.

Type 1: Electric Wall Units

Electric wall units are a popular choice for both new installations and retrofitting existing homes. Utilizing resistance coils, these units convert electrical energy into heat, which is then emitted through the wall surface. The embedded wiring not only enhances aesthetic appeal but also ensures efficient heat transfer. Often, electric wall units are equipped with:

• Adjustable Thermostats: Providing users the ability to control the desired temperature easily.
• Fan Mechanisms: Enhancing heat distribution and ensuring even warmth across the room.
• Energy Efficiency: Many modern units boast high energy efficiency ratings, helping homeowners save on utility bills.

Type 2: Gas Wall Units

Gas wall units offer an alternative heating solution that relies on natural gas or propane for combustion to generate heat. These units are ideal for regions where gas is readily available and can be more cost-effective over time. Key features include:

• Quick Heating: Gas units tend to heat spaces more rapidly compared to their electric counterparts.
• Multiple Venting Options: Depending on local codes, they can be vented through the wall or roof, offering flexibility in installation.
• Continuous Operation: As long as gas is supplied, these units can operate without the constraints often associated with electricity outages.

Installation Considerations

Both types of wall units require careful consideration during installation:

• Ensure that adequate wall depth is available to accommodate the unit.
• Electrical wall units must adhere to local electrical codes, including correct wiring and circuit breakers.
• Gas wall units need proper venting and safety checks to ensure safe operation.

Conclusion

As HVAC professionals, a thorough understanding of wall heating units—both electric and gas—can significantly benefit your service offerings. With their efficient heating capabilities, customizable features, and potential energy savings, these units remain a popular choice across a variety of applications. By knowing the nuances of each type, you can better advise clients on what will suit their needs best, ultimately enhancing their comfort and satisfaction.
