Hello dear home builders,

we have started building a single-family house. The approved building application also includes a gas heating system, which we still want to keep. There are 2 possible scenarios:

1. What happens if the heating system is installed in October 2023, but the house is not accepted until February 2024?!
2. What happens if the heating system is only installed in January 2024 and the house is accepted in May 2024?!

Both possibilities are difficult to plan. So far, we do not know if the construction period could be delayed. I have not found anything on this. Do you have any further information?

Regards Robert

What reason is there for sticking with gas heating - especially in a single-family house? I could still explain for apartment buildings and semi-detached/terraced houses.

To me, the project is like trying to buy a new car with a diesel engine next year.

In my opinion, problems are the depreciation due to outdated heating technology and, in the long term, also the replacement obligation.

If it’s because of the price of the heat pump, then a sincere and open-ended conversation about the technology or the manufacturer might be worthwhile. In direct sales, there are reasonable all-in sets with monoblock and R290 around 10k. Additional cost Vaillant in a set around 5,000 euros – especially if you can do without the gas connection and the additional piping with solar thermal.

Strange comparison. The condensing boiler is the latest generation turbo diesel, a naturally aspirated diesel is more like an oil heating system. The heat pump is the electric car. I would currently still go for a gas heating system. Alone because, due to the lack of large storage capacities, we will still be operating heat pumps in winter with coal power until the 2030s... which drives up the electricity price (the construction of large storage solutions and the massive expansion of renewables also drive up the electricity price, by the way).

In 2035, I might consider a heat pump. If by then no hydrogen economy has emerged and one simply continues to operate their gas boiler with green natural gas.

No one who also studied electrical engineering has been able to explain to me where one would get the nearly 5,000 petajoules of heat needed in Germany. Most of it in winter, when the sun shines weakly and the wind occasionally doesn’t blow for several days... unless through huge, yes gigantic storage.

PS:
And because you can get a gas heating system faster. Delivery times for heat pumps are currently probably between 6-18 months, depending on the model and how good the customer's connections to the manufacturer are.

But that is only due to the "established" manufacturers, as the craftsmen can make really good money with them. For example, if you order a Panasonic heat pump today, you can install it next week if you order it today. But the craftsmen are not keen on that because the margins are lower. The 5kW monoblock costs only €3,600 ready to connect, the split device only €5,100 (even with R32 refrigerant, since from 2025 you may no longer use 410a in bi-devices). And that with German dealers. So delivery times for heat pumps are not fundamentally a problem.

And price-wise, the Asians are even cheaper than the gas boiler. So I really see no reason today to stick with gas. Especially if the house is built to KfW 55 standard or better and the power consumption is very low. I don't really care about the electricity price in that case. Whether I heat the house with €600 or €800 electricity, you don't really notice. Gas is simply outdated.

P.S. Diesel in any form has been out for years by the way. Sales have dropped by about two-thirds in the last 5 years. So you’re making a great comparison that also puts the gas heating system in the "no longer up-to-date" category.

Nothing has happened. Therefore, don’t panic and feel free to install a gas heating system. So far, only green daydreams have been discussed in public and there is a draft law.

Currently, nothing is forbidden or decided.

Your gas heating system will last twice as long as a heat pump and will be significantly cheaper.

Anyone who still installs a gas heating system in a new building today either has blinders on or is stubborn and thinks they are particularly clever. Gas heating systems will be politically penalized in the near future. Follow the mainstream - order a heat pump!
