Hello everyone,
We are planning a new build with approximately 190 sqm (2,045 sq ft), two stories, without a basement. The attic, about 65 sqm (700 sq ft), will be converted to include a bathroom and a storage room. The house will have a brick veneer exterior and will be built according to the energy-saving regulations. It is for a household of five people (2 adults + 3 children).
A mechanical ventilation system with heat recovery and KNX home automation are planned (if the budget allows, specifically for the KNX).
Once the house is completed, I would like to add solar thermal and photovoltaic systems after a few years.
I’m having trouble deciding between gas heating or a heat pump.
The gas connection costs me €2,500.
Could you help me make this decision?
And which manufacturer would you recommend?
Thanks!!!
Regards

Well, I guess you can provide the long-term studies on this right away(?).I can’t provide any studies. In fact, I have heard this from installation companies several times. If I’m not mistaken, I also read somewhere about a service life of 15 years.... Yes, you can now argue that I can’t prove it, and you would be right.Regarding the carbon tax: that is definitely an interesting point. Is there any reason to seriously consider it?

Always promoting photovoltaic yourself, but dismissing others' statements as wrong without arguments. I am neither promoting photovoltaic nor labeling anything as wrong.
I said that one is my opinion, and gas is his opinion.

You’re only suggesting that because that’s what you have!
But if a gas connection is available, then add solar: cheaper and more convenient.
Considering other options only starts when gas isn’t possible. That’s true, I spent a long time researching before building my house and I believe it is the best solution (for my specific conditions). Gas is also available in my street.
No one benefits from slogans like “Only gas, nothing else.”
The fact that some installers say things like “We’ve always done gas; that new stuff isn’t any good” is nothing new—it applies across all trades, especially with older installers.
Heat pumps only gained widespread acceptance in Germany about 15 years ago, and since then the technology has improved by leaps and bounds. Therefore, any statement about long-term durability cannot be considered reliable.
I can only agree with Lumpi here... such slogans don’t make sense in a discussion forum. I wouldn’t presume to say that the combination of heat pump and photovoltaic system is a cure-all.
I can only share my experience:
We built in 2017 with an air-to-water heat pump and added an 8kWp photovoltaic system last year. We are very satisfied with this combination. Currently, we pay a monthly electricity advance of €153. This covers our entire electricity consumption, including the heat pump and controlled mechanical ventilation.
We receive a feed-in tariff of €74 from the grid operator, which leaves us with €79 in electricity costs per month. Additionally, we consume on average 30% of the electricity we produce ourselves at home.
Of course, this must be weighed against the initial cost of the heat pump.
How long the heat pump will last remains to be seen. However, I don’t believe it will be “worn out” after 15 years. Of course, parts can break, but they can also be repaired or replaced.
If I had had the choice back then (budget was limited), I would have chosen a ground-source heat pump. They are even more efficient.
For us, the environmental aspect was also one of the main reasons to choose a heat pump instead of a gas boiler. I want to do my part in the energy transition and am willing to pay more for it (if that turns out to be the case).
My wish would actually be for a battery to store excess energy during the day and use it in the evening/night to minimize electricity drawn from the grid. However, batteries are not really economical yet, and their environmental impact is not exactly favorable either…

That often means you only keep about half of it.
