Hello,
we also have a gas connection on our plot that we can have installed for €2,000.
We are currently considering which option is better. We plan to build a single-family house with 130sqm (1,400 sq ft) of living space and a full basement, designed as a KfW55 house. A photovoltaic system is also planned, intended to cover heating and general electricity consumption. We are a family of three (2 adults and 1 child).
No matter how we search, we can’t really find a way to compare the costs and benefits. What are your experiences? Which is better, more efficient, more cost-effective in the long run, and easier to maintain: a gas heating system or an air-to-water heat pump?
Thank you very much in advance.

Given the current political situation and how things look for the future, gas prices will rise significantly more than electricity prices.I completely disagree.If we don’t want electricity from nuclear, coal, or gas, where will the power come from? Wind energy? No, the government is currently drastically slowing down its expansion. The sun doesn’t shine in winter.
I’m not a fan of fossil fuels, but unfortunately, they are the right choice for the wallet.

As I said, I think heat pumps combined with photovoltaic systems make sense. So, you shouldn’t fully base calculations on market electricity prices, but partly on self-generated electricity. How much you can use should be calculated or estimated individually.

hampshire5 Jan 2020 00:21What consumers pay today is quite disconnected from the actual production costs. While consumer prices are rising, electricity on the market is so cheap that modern gas power plants are being shut down, and fully depreciated coal plants are still running. The system is quite dysfunctional. Expensive is what should be expensive, and cheap is what should be cheap.
This really frustrates me, so my goal is not only to find the most affordable solution but above all to achieve a high level of self-sufficiency.

The great thing about electricity is that it can come from many sources, including gas or oil. If one primary source becomes too expensive, unpopular, or otherwise controversial, another source is simply used. This keeps production costs stable. What mainly changes are the fees, which are influenced by politics.
Currently, politics is focusing on electricity, so we follow suit. It’s that simple.
There is nothing more universal than that.

I haven’t done the calculations, but I would argue that if you want to store solar energy from summer in a hydrogen tank to use in winter, it will be very expensive and require a very large storage system. I dare say this is more than uneconomical. Take a look at Switzerland, where this is already being done in multi-family residential buildings. These buildings are completely off the electrical grid. They have photovoltaic panels installed on the roofs and exterior walls, and hydrogen is produced via electrolysis during summer, with no energy fed back into the public grid. The rents for residents are not much higher than usual.
Gas heating systems could also be operated ecologically (as we mentioned earlier in the thread). In my opinion, both heat pumps and gas condensing boilers have their justification.

The sun doesn’t shine in winter. Without a solid, reliable pillar that isn’t dependent on weather, wind, temperatures, etc., it won’t work! Low-carbon nuclear power, as can be seen by looking beyond borders, as specki nicely puts it.
But that is subjective, just like the choice between a heat pump or a gas boiler. Only in 10 to 15 years can you say, “That was the right decision,” or, “If I had chosen the other, I would have saved some money.” What matters is to stay flexible and be able to convert in a few decades (underfloor heating, low flow temperatures).
