ᐅ Gas-powered fuel cell

Hello,
Since I am currently looking for a new heating system, I came across gas fuel cell heating.
Does anyone have experience with these heaters? What are the purchase and maintenance costs? Is the extra expense worth it compared to a conventional gas boiler?

I look forward to informative answers and thank you in advance.

That doesn’t make sense.
Why would you generate electricity with gas and then convert it back into heat? Also, hydrogen first has to be reformed from the gas.
All these unnecessary conversions reduce efficiency.
Photovoltaics are much more practical for electricity generation.

I work in fuel cell development and can only advise against it.

Well, he specifically wants to heat. At least here, heating is usually done during the winter months. Unfortunately, that's exactly the time when only about 20% of the annual total photovoltaic electricity is produced. Sometimes there are days or even weeks without any significant photovoltaic power, for example now in January or December. What would you, Inkognito, recommend for such a situation?

I would rather consider a combined heat and power unit depending on the heat demand. This makes more sense in older buildings than in new constructions.

Otherwise, with a KfW 55 standard new build and a gas boiler, you almost pay more for the standing charge than for the actual consumption; financially, there’s not much more you can save.

Such systems are subsidized with 40% of the costs.

Hang in there until the sun shines again.

Gas is fossil fuel and will become more expensive (CO2 tax). Electricity is more likely to become cheaper. Also, the technology is not yet fully developed.

Heat pumps are also subsidized up to 35% of the costs.

Bold claim... Where can I buy that crystal ball?
