ᐅ What is a reasonable cost for a new gas boiler?

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.

You really should take some time to read up on how climate change is progressing. And with such low energy consumption, you should definitely switch to a heat pump right away!

No, a heat pump is not possible here because this is a former mining area.

Air-to-water heat pumps should also work in mining areas. Only a box will be placed in front of the house.

No, seriously: we need to be climate-neutral within 15 years. Gas won’t be a viable option. Do the next generation (and probably your wallet) a favor and switch now.

Someone needs to install the new boiler as well. This person usually sets the prices, and the range can vary significantly depending on the work involved. This can generally only be clarified with an on-site appointment.

Let’s wait, soon gas will be green energy :p
When it comes to the boiler, performance, features, and so on are important. Installation costs are additional. Just get a local provider to take a look.
A new gas boiler is definitely more efficient since it will be a condensing boiler. The installation effort is much lower compared to switching to a heat pump.
With the money you save, you can heat for many years. Electricity won’t get cheaper either. At the moment, it doesn’t look like Germany will return to nuclear power. We might just buy from neighboring countries instead…
