Without inertia, heat pumps in old buildings achieve 11% higher efficiency
Fast-acting surface heating systems in drywall construction make it possible.

Retrofitting underfloor heating is easier than you think. | The IDEAL underfloor heating system is suitable for retrofitting in floors, walls, and ceilings in private homes, commercial properties, and public buildings.
Undoubtedly, the efficiency of heat pumps depends on the heating water temperature of the entire system. For economical operation, they require underfloor heating instead of traditional radiators to increase the heating surface area in the room, thus allowing for lower heating water temperatures. Underfloor heating systems like the IDEAL, as they enable rapid heating and cooling: heating only when needed. As a result, modern underfloor, wall, or ceiling heating systems can save up to 11% more energy in older buildings, as a study by ITG Dresden demonstrates.

The proven IDEAL CLASSIC EPS 30 system consists of 30 mm thin insulation panels with factory-applied aluminum heat-conducting plates. In addition to polystyrene, natural insulation materials such as wood fiber and, more recently, straw insulation are available as core materials. The heat-conducting plates ensure high energy efficiency and uniformly rapid heat dissipation, as they distribute heat across the entire surface.
The advantages are undeniable: underfloor heating is energy-efficient, comfortable, and allows for flexible interior design. Modern surface heating systems like the IDEAL system make it easy to retrofit older buildings with underfloor heating, enabling heat pumps to operate efficiently during renovations.
IDEAL can also be used as ceiling heating while the building is occupied.
The option of installing ceiling heating/cooling is a simple yet effective solution, particularly during energy-efficient renovations or refurbishments, when retrofitting underfloor heating is not feasible, for example, because a valuable floor covering needs to be preserved or the living situation doesn't allow for the work. The IDEAL ceiling heating system can be installed with minimal structural intervention and can be used on both solid and suspended ceilings. This allows for room-by-room renovations, and the process is so clean that the entire renovation project can be carried out while the building is occupied. This also makes it possible to implement the conversion over a longer period as part of renovation work, in preparation for a future upgrade to a heat pump. The IDEAL surface heating system also operates on the principle of radiant heating when installed on the ceiling. Unlike conventional convection heating (room air heating), it generates pleasant radiant heat, which warms surrounding surfaces and objects, creating a comfortable and pleasant indoor climate. The floor is also pleasantly warmed by this radiant heat.
Soothing, gentle cooling, completely without side effects
Especially when installed on the ceiling, the IDEAL radiant heating system, in combination with a heat pump, offers a dual benefit: heating in winter and cooling in summer. Many heat pumps can provide cool water in summer, which then flows through the IDEAL system. This lowers the room temperature by an average of four to six Kelvin. The cooling process is completely silent, without any disruptive operating noise or unpleasant drafts, further enhancing comfort and well-being.
The IDEAL underfloor heating system offers energy-saving system solutions:
- Optimizes the performance of your heat pump for maximum efficiency
- Reacts instantly to improve your comfort
- Highest efficiency and effectiveness
- Versatile use: Suitable for floors, walls and ceilings
- For private homes, commercial properties and public buildings
- It offers double the benefit: pleasant heating in winter and refreshing cooling in summer
- Renovate easily. Benefit in multiple ways. Even while occupied.
