Hello, we own a 20-year-old house with a wall-mounted boiler.
Model: Sieger HG11.
Since our exhaust gases are vented through a wall connection rather than through the roof, the boiler’s hot water output was limited to a maximum of 24 kW.
Now our boiler is nearing the end of its service life, and before requesting multiple quotes, I wanted to kindly ask here what the cost might be.
A new wall-mounted unit is to be installed, preferably again with a wall vent. The local chimney inspector has approved this.
Our house has a heated area or living space of 110 m3 (3,885 ft3).
Annual gas consumption is approximately 11,000 kW.

I believe the suggestion to consider a heat pump here is justified. This is a forum, and if up to now only gas boilers have been mentioned, it is perfectly reasonable to bring up heat pumps. Dismissing them outright as nonsense (or something similar, I don’t recall the exact wording from page 1) is not entirely fair.
There are many families (including us) who are already heating with an air-to-water heat pump. We anticipated the situation and signed an electricity supply contract at a fixed price until the end of 2022 back in late 2021. Currently, we heat our home for less than €54 per month (approximately $58) – covering heating, domestic hot water, and ventilation. No gas boiler can compete with that given current gas prices.
Beyond that, using gas makes you highly dependent on the countries supplying it. At the moment, our reserves are so low that it’s even making headlines in the media.
Regarding the topic of China/Xi and their impact on CO2 emissions: As much as I dislike or want to defend the Chinese regime and their human rights practices, a lot of what is said about them is simply wrong. I can warmly recommend the blog by "Graslutscher." He has written a very detailed article on China and climate change. It takes about half an hour to read but is very well organized, thoroughly researched with many sources, and highly interesting.

You want everyone here to install a heat pump for environmental reasons.
With a smaller global population, the climate problem would be less severe or even solved.
On the topic of greenwashing:
If you want to be environmentally friendly, you shouldn't build a single-family house. The heating system alone can’t compensate for that. The resource consumption can never be recovered.
Claiming now that a heat pump is the solution is greenwashing.

By the way, your last paragraph is simply a lie and—as always—is not supported by any figures.

@kati1337 So, you decided for financial reasons.
But that has nothing to do with the topic that @Deliverer always brings up here (climate).
If environmentally friendly heating technology were always cheaper (total cost of ownership), this discussion wouldn’t exist at all.
A heat pump is not always sensible or cheaper. It depends on many factors.
For a new, well-insulated house that isn’t too large, I would also install a heat pump.
In colder regions, large houses, multi-family buildings, or when a high peak output is needed, gas, combined heat and power (CHP), etc., is better.

When it comes to the climate topic, I think it’s like with many other things in life. Finger-pointing and “but he pushed first!” won’t help us as a society. We all need to take action. And my basic approach to life is to start somewhere and lead by example rather than pointing fingers and saying “I won’t do anything until Peter stops.”
We are acting on other fronts too. For example, I no longer cruise with AIDA (which really hurts, even if it’s hard to believe) until they offer something renewable in their fleet. These ships emit way too much unnecessary CO2. I’ve also communicated this to them on social media and to the consultant who always asks if we want to book again. I fly much less than before, and when I do fly, I at least offset my emissions. I switched to a remote job so I don’t have to commute anymore and I drive less than 2000 km (about 1200 miles) by car per year. Hopefully soon electric as well. Our entire house uses no non-renewable energy sources, and I’m a bit proud of that. I’ve calculated my total CO2 footprint, and although like everyone I could still improve, I think I’m among those who are “ahead” in this regard. 🙂
@Deliverer No, I definitely do not recommend that and I never mentioned any subsidies.
Everyone who is concerned about the climate has to decide for themselves what to give up and what not to.
What impact does having a child have on the global climate? Can you offset that with your heat pump? No, you can’t.
So you are putting your personal desires above the goal of saving the climate. For you it might be children, for someone else it might be wanting to travel long distances, and so on.
From my point of view, that is legitimate. Just don’t judge others if you yourself are not doing everything you can or accept that priorities are different.
