At home we heat with a geothermal probe. This type of heating is very new and extremely environmentally friendly. You also need less energy for this type of heating.
Here are a few more facts:
Low heating costs
A heat pump consumes 3x less energy than an oil heating system and basically has the lowest operating costs compared to other heating systems.
Without CO2 emissions
The heat pump draws heat from the environment and releases it within your own four walls. 100% sustainable, 0% CO2 emissions.
100% Independent
No more need for heating oil or the chimney sweep. A heat pump in combination with solar power is 100% independent of external resources.
Low maintenance & durable
Heat pumps require hardly any maintenance and have an average service life of 20 years.
When we moved into my house we changed the heat source from oil heating to geothermal heating. We use geothermal probes in combination with heat pumps to heat our single family home. When they build the new heat source they had to go to dephts of 250 meters.
This energy we do not just use to warm our house we also use it to heat our water. My mum wanted this type of heating, because it is extremely environmentally friendly and you also need less energy for this type of heating.
The energy potential is enormous: 99% of the earth is warmer than 1000 °C. And geothermal energy also has many advantages in terms of environmental friendliness: no burning of fossil fuels and thus no harmful emissions.
We heat our house with oil. As many people know, it is unfortunately not very environmentally friendly. This is due to the high pollutant emissions that occures as soon as the heating oil is burnt for heat. We therefore intend to replace our heating system in the near future, but we are not yet sure what to do. It's also a bit more complicated because all the neighbours have to agree to the new idea.
Our heating source is the geothermal heat pump. Geothermal heat pumps, sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature.
As with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.
My father told me, that for our house they drilled down 102 meters in the ground, which is very impressing.

Sadly, our heating source is very energy-consuming and not sustainable, as we are heating with oil. Ever so popular and cheap, oil heating has been around since the second world war. However, it's a fossil fuel and therefore not renewable. On top of that, the process of creating heating oil creates tons of CO2 with all the drilling and refining. It's an environmental mess.
I was not able to get access to the heater itself, but I was able to photograph the control unit. I am sorry for the image quality, but it's extremely moisty in there.

We heat with a heat pump. Heat pumps extract natural energy from the earth, air or water and thus significantly reduce your heating costs.

Why is a heat pump worthwhile?
- Independence
The heat pump makes you independent of fluctuating [1] oil or gas prices
- Low heating costs
You save up to 75 % on fossil fuels
- Flexibility
You can enjoy comfortable domestic heating [2] as well as optional hot water and domestic cooling [3], expand your heating system to a hybrid system and integrate other renewable energies if you wish.
- Environmentally conscious
They produce up to 50% fewer emissions
- Comfort
Heat pumps require less maintenance [4]

- Why does jupiter have so many moons?
- Why does jupiter have a big red point? What's the reason?
There is a plan for a new kind of city with big public transports. The space of the city would be well planed and the mobility would nearly be perfect. An example of such a city is "Neom". Neom is an project idea of the arabic gouvernement. The plan is to start in 2030 with the project. Neom is a old greek word and means new. Everything in the city should be new, futuristic and enviroment friendly.
Are there any bad points about that city? I remember reading an article where the local population is really against building the futuristic city, because the location would be at a local tribe. Are there any "better" projects?

Anabel and I decided, that our project would be on natural remedies and herbal medicine. She made the first step to get in contact with the students in India and now we're waiting for their reply. We created a chat in Teams and a first document where we will stay on top of things regarding our project.
As a team, we decided we would also work with her half-sister, who works in herbal medicine. She can give us the info that we need and also a good insider look.
