HEAT PUMPS – ADVANTAGES AND DISADVANTAGES

As the name suggests, this system involves heating elements installed within the walls. This shares a significant similarity with underfloor heating systems, as both spread heat across a larger surface area compared to traditional radiator systems. Consequently, the water temperature in wall and underfloor heating systems remains lower than in radiator systems.

Advantages of Wall Heating Systems

• Lower Energy Consumption: With water temperatures ranging from 28 to a maximum of 40 degrees Celsius (approximately 82.4 to 104 degrees Fahrenheit), wall heating operates as a low-temperature system, reducing energy losses by up to 30% compared to traditional radiators.
• Reduced Dust Circulation: The gentle heat transfer minimizes forced air circulation, resulting in significantly less dust accumulation compared to radiator systems.
• Enhanced Comfort: The even distribution of heat creates a more comfortable environment with fewer cold spots or overheated areas.
• Space Optimization: Without visible radiators, wall heating offers more freedom in furniture placement, allowing for shelves or tables beneath windows.

Disadvantages of Wall Heating Systems

• Restrictions on Furniture Placement: Furniture should not be placed directly against the walls to maintain efficient heat transfer, which might be challenging in smaller living spaces.
• Complex Installation: Mounting shelves or hanging pictures requires careful planning to avoid damaging the concealed piping within walls.
• Higher Initial Cost: While wall heating provides numerous benefits, its installation cost is generally higher, especially when opting for drywall systems.

Integration and Compatibility

Compatibility with Existing Systems

Wall heating can be integrated into existing central heating systems, replacing traditional radiators. However, this transition might not be practical in properties with centralized heating due to technical and legal constraints.

Optimal Pairing with Heat Pumps

As a low-temperature system, wall heating pairs seamlessly with heat pumps, ensuring efficient operation and maximizing energy savings. Heat pumps, extracting heat from the air or ground, complement wall heating during both heating and cooling seasons.

Efficient Cooling Option

During summer months, wall heating systems connected to heat pumps efficiently cool spaces by circulating chilled water through the walls, avoiding the direct blast of cold air associated with conventional air conditioning units.

Installation Options

Wall heating systems can be installed through two primary methods:

1. Embedded Pipes with Plaster Overlay: This cost-effective method involves embedding heating pipes within walls, followed by plaster and finishing layers.
2. Drywall Systems: Alternatively, specialized gypsum boards containing pre-installed piping offer a more streamlined installation process, albeit at a higher initial cost.

Conclusion

While initial costs may deter some, the undeniable benefits of wall heating and cooling systems make them a compelling choice for comfortable and energy-efficient living environments. Optimal integration with heat pumps further enhances their efficiency, offering year-round comfort with reduced environmental impact.
