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.

Sorry, but your last post here just leaves you shaking your head....This must be that so-called constructive way of discussing everyone talks about.... lol
@michert The article features several engineers, including this one:
"I assume that heat pumps are now heavily subsidized," he says. "In 20 years, we will realize that this is not a particularly efficient method of heat generation, and new programs will start for phasing them out—just like with the old night storage heaters back then." I interpret this to mean that, in 20 years—if what this engineer predicts comes true—the disposal of millions of heat pumps will be considered hazardous waste.I don’t have the time to break this down right now. The kids need my attention.
But maybe think about it yourself and question that strange article a bit.
What kind of hazardous waste should it be?
Why would a properly planned heat pump be inefficient? When combined with a decent photovoltaic system, it’s basically impossible for it to be inefficient.
Have you done thorough research on hydrogen? If so, you probably wouldn’t write something like that. Photovoltaics plus battery storage make much more sense than hydrogen.
That’s all I can say for now. Just question things yourself.

ludwig88sta4 Jan 2020 13:50Heat pumps require increasing amounts of electricity, which will not be available. And it is not supposed to be, because the federal government has actually set a goal to reduce electricity consumption by 25 percent by 2050.Is there some truth to that, right?

Did you actually read the article, or why do you find it "strange"?
Let me guess, you have a heat pump plus photovoltaic system?
It’s always the same: many homeowners defend their system to the death and try to suppress (sometimes justified) criticism right from the start—clearly here in an unprofessional and childish way.....
