ᐅ Air-to-Water Heat Pump: Current Consumption and Data

Self-sufficiency through photovoltaic systems and eventually energy storage becomes increasingly worthwhile. However, this conflicts with the expectation that storage solutions will become significantly cheaper in the medium term. The margin gained through development and economies of scale will likely be captured by someone earlier in the supply chain. End consumers can then be happy about every kilowatt-hour of self-generated and used electricity since it would cost around €1.

However, I believe that storage should be handled in a centralized manner. This approach would also make it feasible for energy producers or grid operators to implement processes such as hydrogen generation through electrolysis on an industrial scale.

What I forgot to mention: Photovoltaics currently generate about €400 per year from feed-in. Still, it is not cost-effective.

If I were to believe that, I might just believe in Santa Claus too, but the conditions are being set up so that gas is no longer an attractive option.

What is certain is that politics has already set the end of fossil fuels in motion, and the next government will certainly be greener than the current one.

Whether you like it or not, that’s the current situation.

My photovoltaic system is working wonderfully 😉

The CO2 tax and its expected increase are well known. After the election, it might even rise more sharply than previously planned. This mainly affects gas and, to a lesser extent, electricity.
Politically, there is a will to cap electricity costs (Renewable Energy Act surcharge already in place).

Today, the gas bill for 2020/21 arrived, following the electricity bill. Electricity 1900 kWh, gas 9300 kWh, both per year. I’m not sure if that’s great, but I’m quite satisfied. Gas costs about €500 per year, electricity around €600, so energy costs are roughly €100 per month. We only generate hot water via solar panels. That’s used directly. Nothing is sold back.
There are two of us living in an energy-saving regulation bungalow made of solid Ytong, with about 110 m² (1,184 ft²) living area.

Heating costs of €500 in absolute terms are definitely quite reasonable.
However, I heat 200 m² (2,153 ft²) with four people for the same amount. So, your consumption is probably not optimal.

We currently have household electricity costs of €1200 and €1000 for the heat pump, which means energy costs just under €200 per month. This is tending to rise, as we want an additional freezer, more electric cars (I really want a fun vehicle with real power ..) and a hot tub. 😀

Any thoughts about the hot tub? It’s also a small dream of mine, but I can’t bring myself to use as much electricity for the hot tub as for the entire house.

By the way, my electric car has so far only been charged with my own photovoltaic electricity (except for the initial charge at the dealership).
This further improves the return on the photovoltaic system, like any self-consumption does.

I don't care. I have no interest in living in saving mode; you can't take it with you when you're gone. K.
