Energy-efficient construction and renovation for more climate protection

The demands that the German Buildings Energy Act (GEG) places on residential companies in Germany are growing all the time, creating significant challenges for construction projects.

Achieving climate goals means taking action quickly. In order to meet minimum standards, which themselves are constantly increasing, the energy efficiency of products has to be one of the key factors considered in planning and decision-making processes in the housing sector. While it is important to acknowledge the pressure to renovate existing buildings using fast, eco-friendly methods, the challenge for the property sector lies in maintaining a sense of proportion and foresightedness when evaluating the right efficiency measures for the project in question. There is a balance to be struck between using methods that prioritise climate protection and creating affordable places to live.

An unbeatable combination

Energy-efficient renovation with money from the state.

Using heat pumps is one method that can be used in renovations for fast, energy-efficient, and – most importantly – economical results. Low multi-storey buildings are one example of a project that often reaps real benefits from renovation for energy efficiency. By replacing the old, ineffective heating system in a block of flats containing up to 15 housing units with modern x-change dynamic heat pumps in a cascade, it is possible to create more than just benefits for the climate: failsafe performance, maximum efficiency, automatic running time optimisation, the utmost flexibility, and state subsidies are just some of the advantages that property owners report in the aftermath of replacements. However, some people are still reluctant to make the switch from oil or gas to renewable energies because the radiators they are already using are dimensioned for the high flow temperatures that oil and gas burners demonstrate. Switching to panel heating is not always a seamless process: the amount of work involved and the costs can often be excessive.

The simple solution

One solution is to use the existing radiator connections and replace the old radiators with high-performance ones that are suitable for the heat pump – without the need to perform any time-consuming structural measures or uproot the property’s residents. The special x-flair heat pump radiator is designed for the low flow temperatures delivered by modern heat generators and ensure a comfortable level of feel-good warmth.

Best of all, 

both heat pumps and the x-flair heat pump radiator are fully eligible for subsidies.

x-flair – THE heat pump radiator

The energy-efficient solution

The x-flair heat pump radiator is equipped with x2 technology that works on the basis of the serial flow principle and a high proportion of radiant heat, allowing the radiator to make optimal use of the low flow temperatures of a heat pump. The key feature is the innovative fan system: thanks to the integrated axial fans, the heat is distributed around the room particularly quickly as required – for maximum thermal comfort, even at flow temperatures between 35 °C and 55 °C.

This allows the whole heating system to be operated much more energy efficiently.

The fans switch on and off fully automatically as needed, operate extremely quietly, and are protected by the top cover.
