Weekly review cw 23
I've been thinking about green energy lately: heat pump + photovoltaics, yes or no? Why are companies changing adapters, connectors, and the like? Don't they have better ideas to stimulate consumption?

Relaxed exercise week with a new component
My physical therapy for my shoulder starts this week. Thanks to the cortisone injection, I'm pain-free for now. To keep it that way, I'm learning the correct exercises to stabilize my shoulder. I'm glad I'm not restricted in my running. I'm still holding back on intensive table tennis training. The same goes for strength training.
Last week, I cancelled my subscriptions to my streaming services, which freed up time in the evenings. I'm now using this time for yoga. Running and daily desk work have significantly shortened the tendons. I'm hoping yoga will improve my mobility. Time will tell if that works. What I can already say: It's incredibly fun and incredibly relaxing. The idea of pausing and being grateful for the few days I have with a healthy body was an extraordinary stimulus from the virtual yoga instructor.

Tricky decision: Heat pump + photovoltaics
From a purely ideological perspective, the decision isn't tricky, but crystal clear: Put the system on the roof and get the green electricity. Thinking a little further, the analysis isn't so simple – how green is the production, and later the disposal? That's a different issue, one I find challenging to research and even more complex to assess.
Apart from that, I look at the whole thing from an economic perspective: An investment over twenty years or more should be well-thought-out. I'm currently planning to rent a system through the provider Enpal instead of buying it to reduce cash flow. Of course, I'll pay more overall and receive some benefits in addition to the services. But are the benefits worth the extra cost? At my age, a 20-year investment horizon means an expense that will extend well into my retirement. I haven't decided yet.

Replacing major appliances in the kitchen
Our oven has been acting up lately. Instead of maintaining the set temperature, it's getting extremely hot. Depending on the contents, this could be compensated for by closely monitoring it. The granola or pizza cooked faster. A cake is a different story. So, after 14 years, it was time to get a new appliance. My first thought was to call Küchen-Aktuell, order a new oven, and have them install it. I could already see the money flying out the window.
Thanks to YouTube, I found videos showing how easy it is to remove and install it with a plug, at least if a standard Schuko plug powers the oven. After a quick check, I determined that the plug connection works for me. After 30 minutes of research, I found an inexpensive model, which was delivered two days later and replaced within an hour. To complete this, I had to loosen two screws and put in two new ones – in different places, of course. Why should it end up being attached in the same place, even if it's from the same manufacturer and the same model series? I'm probably too naive for this world.
The same thing happened to the inside of the oven. I have telescopic rods that guide the tray horizontally out. This component can be replaced. The new oven shifted the brackets by exactly one centimetre, so I have to purchase the telescopic system from the same manufacturer and the same model series instead of reusing it. It costs a mere €150, and what's worse, these deliberate changes serve only to stimulate consumption. I get furious about such injustices. It's deliberately provoked waste. Simply disgusting of Siemens!
