Energy efficiency

A house quickly loses 20 to 30 percent of its heat through the roof - especially if the insulation is outdated or non-existent. For owners, roof insulation is therefore one of the most effective measures for increasing energy efficiency. It reduces heating costs, improves the indoor climate and increases the value of the property - often with state subsidies. Differences in the...

As the heating season approaches, owners should not forget one thing: to bleed the radiators in good time. This is because air in the system can significantly reduce the heating output - the heating hisses, remains cold at the top and consumes an unnecessary amount of energy. The good news is that you can fix this problem yourself in just a few simple steps - and save money. How do you recognize air in...

Roller shutters are more than just privacy protection - they improve thermal insulation, keep the heat out in summer and provide additional insulation in winter. For owners who want to optimize the energy efficiency of their home, retrofitting roller shutters is therefore a worthwhile measure. At the same time, it increases living comfort and can also improve burglar resistance - a plus for the entire...

In times of rising energy costs and growing interest in ecological heating systems, wood pellet heating systems are becoming increasingly important. This technology offers an attractive alternative, especially for owners who want to rely on an independent and CO₂-neutral heat supply. But what are the benefits of heating with pellets - and what should owners look out for? Sustainability...

If you want to heat your home sustainably and reduce energy costs at the same time, solar thermal energy can be an attractive solution. Unlike photovoltaics, it does not generate electricity, but heat - ideal for heating water and supporting the heating system. Particularly in well-insulated houses, a high proportion of the energy can be covered by the sun -...

Heating costs are a significant part of the running costs of a house or apartment. Smart thermostats help owners to use energy more efficiently - and increase living comfort at the same time. The technology is now fully developed, easy to retrofit and often even eligible for subsidies. What smart thermostats do Modern devices regulate the room temperature as required - for example...

Many properties lose energy unnoticed - and therefore cause higher heating costs than necessary. If you know the typical weak points, you can take targeted countermeasures and make a big difference with simple measures. Owners benefit twice over: from lower operating costs and a better indoor climate. Windows and doors: more than just passages Leaky window frames or poorly closing...

Photovoltaic systems are no longer only to be found on new buildings - more and more owners of existing properties are also relying on the power of the sun. The system becomes particularly efficient with its own electricity storage unit. This maximizes self-consumption and significantly increases independence from the electricity supplier. More self-sufficiency with battery storage Without storage, the...

With the boom in electromobility, the demand for private charging options is also growing. More and more owners want to charge their electric car conveniently and safely at home - ideally overnight, at low rates and with self-generated electricity. But what options are there and what needs to be considered during installation? Wallbox instead of household socket For regular charging, we recommend the...

With the rising temperatures in summer, protection against overheating in living spaces is becoming increasingly important. However, not every property is sufficiently equipped for this. Owners can effectively prevent this with targeted structural and technical measures and thus ensure greater living comfort - without the need for air conditioning. External sun protection is best provided by roller shutters, awnings and blinds...
