When deciding on a heating system for your home, it’s essential to understand the differences, advantages, and disadvantages between underfloor heating and wall heating. This guide will help you determine which option might be better for your needs, including the possibility of cooling in the summer and considerations for retrofitting during renovations.
Advantages of Underfloor Heating
Underfloor heating has gained significant popularity in recent years, primarily because it eliminates visible heating elements and works seamlessly with heat pump systems. Here are the key benefits:
- Efficient Operation: Underfloor heating operates at lower temperatures compared to radiator systems, making it an ideal match for heat pumps, which also function efficiently at lower temperatures.
- Energy Savings: Lower operational temperatures result in reduced heat loss, greater system efficiency, and lower energy consumption.
- Comfort: The even distribution of heat across the floor surface provides a more comfortable and consistent warmth throughout the room.
Advantages of Wall Heating
Wall heating shares many similarities with floor heating, such as operating at lower temperatures. However, it also offers unique benefits:
- Dual Functionality: When combined with a heat pump, wall heating can be used for cooling during the summer, providing year-round climate control.
- Space Efficiency: In smaller rooms, such as bathrooms where floor space is limited, wall heating can be more effective by utilizing available wall surfaces for heat distribution.
- Flexibility in Installation: Wall heating can be installed both in new constructions and during renovations. It can be mounted over existing walls, making it a less invasive option compared to underfloor heating.
Differences and Considerations
While both systems have their merits, there are key differences to consider:
- Cooling Capability: One of the most significant advantages of wall heating over underfloor heating is its ability to cool the space when used with a heat pump.
- Installation Complexity: Retrofitting underfloor heating can be more expensive and labor-intensive. It requires raising the floor level, which involves removing existing flooring and installing new layers, leading to higher costs and more extensive renovations.
- Wall Space Utilization: Wall heating requires keeping walls free of large furniture pieces to ensure efficient heat distribution. This might be challenging in smaller homes or apartments.
- Maintenance and Adjustments: Installing shelves or hanging pictures on walls with embedded heating systems can be tricky. It requires precise identification of pipe locations to avoid damage, typically done using thermal imaging while the system is active.

Combining Underfloor and Wall Heating
In some cases, a combination of both underfloor and wall heating systems can provide optimal results, especially in spaces where one system alone might not suffice. For example, combining both systems can enhance heating efficiency in larger rooms or spaces with varied heating needs.
Integration with Pellet Boilers
Many homeowners wonder if floor and wall heating systems can be combined with pellet boilers. The concern arises because underfloor and wall systems operate at lower temperatures than radiators. This issue can be resolved by installing a mixing valve with a thermal head on the boiler, allowing the integration of these heating systems.
Conclusion
Choosing between underfloor and wall heating depends on various factors, including your specific needs, the layout of your space, and your budget. While wall heating offers cooling capabilities and easier retrofitting, underfloor heating provides consistent and efficient warmth. Understanding these differences will help you make an informed decision and create a comfortable and energy-efficient home environment.
