That's German. Not a word, but the abbreviation of a regulation (or so you will an ordinance) the German government issued on 24th August, to become in place 8 days later, today.
In short: we have to stop our whirlpool from heating the water until next March.
In long: the regulation is called: Verordnung zur Sicherung der Energieversorgung über kurzfristig wirksame Maßnahmen (in English: Ordinance to secure the energy supply on short-term effective measures). For those who like long words, the ordinance is also called
Kurzfristenergieversorgungssicherungsmaßnahmenverordnung. Really! Translate.google manages to translate this into English !!
This new regulation forbids several things and demands others, all in order to reduce the usage of energy in this winter. Temperature in official buildings, factories, common areas in other buildings. Closure of doors (!). It forbids the heating of water that is only used to wash hands.
And, it forbids the heating of whirlpools, spas, swimming pools, if they are used by private persons. So hotels can still use them. Saunas are not forbidden. Yet.
By the way, if you produce the energy yourself, with oil, wood, earth-warmth, or solar panels, you are still allowed to continue heating your pool.
Well, we don't do latter, but use the normal electricity network (heavy current), so I could only do one thing: turn the temperature down.
Since a whirlpool with a temperature of 10°C is not really funny, we will run the pool dry tomorrow or the day after. It will cost some extra water, to refill, but that's nothing compared to the energy (€€€) we save when the pumps, daily jet cleaning (twice), and filtering aren't running and we don't have to keep the water clean.

All good stuff. And now we wonder when the government will dare to initiate a speed limit, forbid all SUVs, forbid short-distance flights, introduce tax on kerosene. Just to mention a few things they can do too. And mind you: speed limit can be controlled. But not whether someone uses his whirlpool with public electricity.
