Venting radiators: small measure, big effect on energy consumption 

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...

Retrofitting roller shutters: save energy and increase living comfort 

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...

Heating with wood pellets: how efficient and sustainable is the system really? 

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...

Solar thermal energy for single-family homes: how owners can make optimum use of solar heat 

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 -...

Smart thermostats: How owners save energy and gain comfort 

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...

Avoid heat loss: Recognize the weak points in the house 

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...

Clever use of solar power: Combination of PV and storage pays off 

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...

E-mobility at home: charging options for owners 

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...

Summer thermal insulation: keeping the house cool 

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...

Heat pumps in old buildings: when it makes sense to install them 

Heat pumps are regarded as one of the key technologies for climate-friendly heat generation. But while they have long been standard in new buildings, the question often arises in older buildings: is it worth installing them here too? Check technical requirements For efficient use, the building should be well insulated. Without sufficient insulation, heat pumps work less effectively, as the...
