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.

And obviously, you haven’t read the conditions under which nuclear and gas are supposed to become "green" either.

What does "coming to an end" mean? Is it more of a feeling, or is there really something wrong?
A new boiler would likely be a condensing type, which might require a new flue system (this was the case with our very old chimney, but I’m not familiar with 20-year-old systems). If that’s the case, a heat pump could be an alternative, especially since there are current and expected future subsidies for them.
I would look at this without bias once the details about subsidies become clearer.
If time is pressing, talk directly to a local tradesperson – they are the ones who have to install it, not the internet.

barfly6664 Feb 2022 19:49@Deliverer Your dedication to saving the world is admirable, but hijacking almost every thread here to flood it with your heat pump nonsense can be quite annoying. This thread is about gas boilers, not about how you think the world should be saved.
And “we have to” is definitely not something anyone owes you.
Heat pumps are fine, but what about your overall ecological footprint? Do you skip vacations (plane? car? Or nearby travel)? Hopefully not by car (electric or diesel doesn’t matter, bike or train available)? No mobile phone? Or all that other electronic junk from China (like a gaming console for the kids, for example)? Hopefully not. Does your house have only one heated room (just the living room)? Do at least 20 people live in your large house (because high square meters per person obviously isn’t environmentally friendly either, right)?
I’m genuinely curious. I know someone like that personally (who actually doesn’t have a heat pump, heats his 1920s house with gas—guess the economist in him shows). He tries to tell me (or the whole world) what we should do environmentally, but he’s already had five cars in a few years, drives a hybrid company car despite working from home, goes on trips to Portugal with a caravan, uses an e-bike and e-scooter because he is “eco”… His daughter travels around Europe with Interrail, is into horseback riding (yes, horses have a poor environmental record too), always has the latest iPhone but still joins her father at Fridays for Future protests and once told me “No, I don’t drink beer from cans… out of conviction” when he stopped by for a beer… or tells me what should be done environmentally.
I’d bet my house that my ecological balance, despite having a diesel car in the driveway, a fun car in the garage, and an oil heating system in the basement, is better than some of those so-called eco-warriors’… 😉

Did you see the smiley?
I also didn’t say that we are currently shopping. Just wait until electricity demand rises further and energy from abroad becomes cheaper.
If you really want to be environmentally friendly, you shouldn’t build a single-family house, have air conditioning, travel, or even have children.
Heat pumps in Germany won’t save the global climate. But everyone is welcome to make a small contribution. It’s just better to avoid being preachy. Purely financially, a new gas boiler is the better option in this case.

So just remove the old boiler, install the new one, and that’s it.The initial cost is probably around €2,500 all in for a basic unit. For a proper setup, I would estimate about €4,000 all in.
