Yes to both.

It can be programmed to do so, but I disabled it as I am not particularly concerned about it, and the solar thermal vacuum tubes also connected to the same tank will occasionally push it to near boiling temperatures.

I originally also thought it would be useful to dehumidify the air, but in reality the times when you need to heat water and the same time have a humidity problem rarely overlap in my case. Maybe if you have a perpetually humid cellar that you don't use much otherwise (as the exhaust air is quite cold) it would be a good addition.

I think this is mostly interesting for repurposing existing fossile fuel powerplants.

Add a relatively small geothermal power-plant on site for baseload demand plus a well sized grid battery and you can continue using a lot of the existing infrastructure of these older powerplants.

Due to security requirements this will not work with nuclear, even when using (largely theoretical) small modular reactors.

Noch besser ist eine Präferenzwahl.

I have such an air to water heat-pump. It reaches 55°C without the supplementary electric water heater, which is more than sufficient if you have a hot water tank. The supplementary electric heater is really only used when too many people want to shower in a short timeframe or to occasionally heat the tank up to 70°C+ to kill off any bacteria that might be growing in it.

I don't think you will find a heat-pump with a variable drive compressor like you are proposing, but a DIY solution might be feasible.

But why not just install a vacuum tube solar-thermal water heater? They are more efficient anyways.

Tja, was die Unabhängigkeit der Staatsanwaltschaft angeht hat Italien Deutschland einiges voraus.

Good article, but ugh... flipping houses that you know are going to be flooded soon after is just evil.

Because the entire article is a parody on how western media usually reports on sub-saharan African states.

A bit of googling:

its EPA-estimated combined driving range is 149 miles, but the city range figure is 162 miles

The 500e starts at $34,095

I can see why sales might be a bit sluggish with abysmal figures like that.

Powerful part:

Even if he doesn’t call it anxiety, he admits he sometimes has trouble focusing, and there’s a tenseness in his body that can be hard to shake off. But he’s usually able to turn it around by talking to his friends or elders, or by reciting his favorite proverb:

"They tried to bury us, but they didn’t know we were seeds."

“It’s not about what I need, it’s about what my community needs,” he said. “There is joy in caring for one another. There is joy in coming together to fight for a future that we believe in.”
