- Oliver: you If you a heat pump, a very interesting topic is also variable electricity rates. All power providers have for a long time and for owners with heat pumps, photovoltaics or e-cars it is always an exciting development. Because instead of always the same electricity price, the price here at the power stock and it fluctuates depending on the day time, sometimes significantly. The principle behind this is actually quite logical. If is particularly much wind or solar power available grid, the electricity price often sharply. Sometimes electricity at night or sunny days. And exactly these cheap time windows can be better and today. heat pumps benefit from because modern systems can specifically when electricity cheap. The house or a buffer storage is then preheated and the stored energy is later used when the electricity price rises again. This means that the heat pump works more intelligently and the cost is less The interesting in combination with photovoltaic and battery storage, because the storage does always to with its own solar power. The can theoretically also at night with cheap power supply, for example if there lot of wind power available. And this power again in morning or in the evening when the price is higher. This makes the entire house energy supply much more flexible and electric cars also a role. If your car intelligently, can cheaper price phases and thus reduce the charging costs. And long run, the development will even further. When the so-called bidirectional charge, the car can later the electricity to the house. The vehicle is then practically an extra power storage. The technical possibilities are now there this and legally and practically there is still a lot to in the development. So I would say we take at what you really need to these systems work. First, this a smart meter, i.e. an intelligent power meter. This receives current electricity prices and can devices like heat pumps, memory or wallbox. The smart meter rollout runs rather slowly But 2032, these systems should be to the surface. For many households with heat pumps, larger PV systems or wallbox, this a must and is also quite useful. And if you European countries and our neighboring states, then this already standard The combination of all systems is What this? In photovoltaic, memory, heat pump, wallbox and power prices are Automatically, when which device runs the sensibly. The market is massively. The energy transition means no longer only heating or solar modules. It's about control energy intelligence. and flexibly to the power grid. So, is renovating or rebuilding should only at individual technology, but at the entire energy system in the house. Because the combination of heat pump, photovoltaic, power storage smart meter and intelligent energy management system will probably become the actual standard And even if you an electric car, you can maybe take a look at it.
