Ecologically heating - how can you do that?

Fossil fuels are not necessarily the most ecological way to warm living spaces in winter. In fact, this is much more complicated with the ecology of heating. How to actually heat ecologically, and what to consider, read here.

Renewable energy sources are better

Solar thermal energy, photovoltaics, wind power: Renewable energies are certainly more ecological ways to generate heating heat: at least in comparison to the exploitation of fossil fuels such as oil or gas, which will sooner or later be exhausted anyway.

Renewable energy sources are better - but they also bring their problems. Thus, many solar modules, mainly from cheap production, contain a lot of dangerous toxins such as cadmium telluride or cadmium sulfide. Both are considered highly dangerous to health and carcinogenic. What should happen in the disposal of such modules, is still open.

The production of solar collectors is not without high energy consumption, and thus high CO2 emissions, in front of him. In addition, there are not exactly environmentally friendly production techniques, especially in low-wage countries.

Also wind energy means, in particular on a large scale, a massive intervention in natural landscapes, constant noise pollution and thus a not to be underestimated health hazard for humans and animals.

In addition, the required storage devices for the power generated, which is then used for heating, also a problem. Night storage heaters modern design could be a possibility here, but there is still a mature and proven technology for it yet.

In some cases, regenerative energy sources do not have a 100% positive eco-balance. The already existing problems would only increase significantly with a wider distribution, and would be even more difficult to solve.

Ecologically heat with electricity?

Although the invention of infrared heaters has provided a very efficient and powerful way of converting electricity into heat, heating with electricity from the grid is not altogether very ecological. This is mainly due to the problem of power generation and the resulting high base load, especially in the winter months.

House without heating

The most ecological form of heating is a house without heating. This is also easy in our latitudes. But nobody has to freeze. The heat requirement of a family home can also be covered differently.

Ventilation systems in modern passive houses, which are practically airtight, have a so-called heat recovery. The existing room heat is extracted from the exhaust air and fed back into the supply air. The air is exchanged, the room heat is always retained. Such systems have an amazing 95% efficiency.

These plants can also be combined with wastewater heat recovery to compensate for the 5% heat loss in the long term. In the normal case, however, the waste heat from appliances and from the refrigerator, as well as the body heat of the people living in the house is sufficient to compensate for the heat loss.

This is certainly the most ecological form of heating available. Renewable energy, electricity from the grid and all types of energy sources all have their ecological negative effects. Only the measure is different.
