We replaced our old oil heating system with an air-to-water heat pump in 2019. We had decided on this type of heating to get away from oil. One part of the house is heated by radiator and the other part by floor heating. However, the difference between the two heat exchangers is noticeable. The floor heating is by far more effective. In the living room we also have a wood-burning stove that you can light in winter.

brainstorming electricity today
Today, Alina and I sat together and had a chat about what we want to do for our project.
The supercategory is electricity.
I will focus on electricity today, wheras Alina will have a look at electricity 100 years ago. For the part of electricity in 100 years, we were planning to collaborate.
w/ Alina Z.
The lay out of our work will look more or less like this:

The history of heating
For all of us, a heated apartment has become a matter of course. Especially in winter, we do not have to worry at all, because the latest technology always offers us a warm home. But the road to this goal was long and often arduous. New technologies with more efficient and cheaper fuels were tested again and again. In the end, climate protection also played an increasingly important role. This project deals with the eventful history of heating.
- The beginnings of heating
- The first underfloor heating already existed in ancient times
- More safety and comfort through stoves and fireplaces
- From the oil crisis to ecological heating
Are you aware of how much heating energy you use in your home?
What is used for heating in Switzerland?
What are the most modern heating technologies?
Are there still outdated heating technologies from back then?
Calculation
Experts and homeowners can also roughly calculate the heating capacity using guide values. These depend on the year of construction as well as the construction method of buildings and lead very quickly to initial results in practice. The following table shows how many kW of heating power are required per square metre of living space:
Baujahr
|
bis 1958
|
180 W/m²
|
|
1959 bis 1068
|
170 W/m²
|
|
1969 bis 1973
|
150 W/m²
|
|
1974 bis 1977
|
115 W/m²
|
|
1978 bis 1983
|
95 W/m²
|
|
1984 bis 1994
|
75 W/m²
|
|
ab 1995
|
60 W/m²
|
Example calculation
A 150-square-metre detached house built in 1975 thus has a heating capacity of 17.25 kilowatts (150 square metres x 115 W/m² = 17,250 watts or 17.25 kW).
It is important to know, however, that the values given are only guide values. If old buildings have been renovated in the meantime to improve their energy efficiency, for example by insulating the exterior walls, the real values are usually lower. The heating output may then be lower.

Taming the fire was one of the greatest achievements of the Stone Age. The centre of every family was the hearth, where people ate, cooked and worked. But how did the Stone Age people make fire?
For example, if you work a piece of pyrite violently with a flint, splinters jump off and ignite themselves. If they hit easily flammable material, they start to glow. Blow caPublishrefully and refeed with dry shavings - this is how a fire starts.

Dies ist eine Luft-Wasser Wärmepumpe. Es wird dabei der Umgebungsluft Wärme entzogen. Ein Ventilator saugt diese Luft aktiv ein und leitet sie an einen Wärmeübertrager weiter. Mit Hilfe von Dampf wird dann Wärme erzeugt.
We received some good news from our collaboration partners - they recently sent us the photo material we needed, as mentioned in our previous posts. The pictures aren't as meaningful as we imagined them to be but atleast we received some footage and we decided to work with those. This is a further step to the publication of our project on the web.
We finished drafting our text for the wordpress and sent it to our english teacher to get it checked/corrected. After we receive our corrected text, we might even add or change paragraphs in our text in order to perfectionize it. Then we will transfer it to dontwastemy.energy, bring it in shape and then hopefully publish it on time.
Our team consists four members:
Reyda and Elif from Izmir, Turkey.
Florian and Jasmin from Wetzikon, Switzerland.
