Missing slider description #1012

Spotted it for the warmtepomp (lucht). But possibly also for other new sliders?

Assigned to @wmeyers. Is this something that you could write a snippet about? After @AlexanderWirtz returns he will validate, correct and expand it, right @AlexanderWirtz?

Right now the text under cooling for the same technology is saying things about thermal storage. I will update this one too. Or am I wrongly assuming that with an air heatpump you don't use the ground for storage?

"Thermal storage works by storing a building's heat underground by cooling it with water from a water basin or aquifer in summer. This heat can be used again in winter for heating the building. Alternatively the natural heat of cold of ground water or roads, for example, can be used.

Heat pumps are more efficient when used in combination with thermal storage, because less energy has to be added to cool or heat water to the right temperature. It is difficult to realize underground thermal storage in densely populated areas so this is only lucrative for 'collectives' like housing estates or entire housing blocks."

A heat pump moves heat from one place to another. Heat pumps are used in refrigerators, but buildings can use them for heating and cooling. This saves energy compared to a gas-fired central heating boiler, for example. For optimal application, it does often require installation of under-floor and wall heating instead of radiators. Currently, their use in newly constructed houses is becoming quite popular, since European legislation dictates that domestic energy consumption must decrease.

Heat pumps can run on gas or electricity. This is an electric heat pump and it draws its heat from the air. Heat pumps and micro-CHPs are not a very useful combination.
