Installation of a gas heating system in new construction 2023/2024

I agree, we need to tackle this properly. But for me, a few small things can also be done alongside, especially if they have other positive side effects. The problem is that society as a whole keeps getting bogged down in the small things and ends up stuck.

This is also an opinion that some people hold. "It's already too late anyway, better to work on better airbags and seat belts." However, in my opinion, they underestimate the consequences of hundreds of millions of people around the equator losing their livelihoods. I cannot and do not want to imagine what we will then be forced to do.

To get back on topic a bit: Apart from "I don't want to because Habeck says so," what technical(!) reason would there be to install a gas or oil heating system in new construction?

Unfortunately, you have to come up with a certain number of words and letters here. As an answer, you couldn't just give a plain "none."

With an RHM, depending on the federal state, you could have problems with distances. I cannot imagine that with a single-family house.

Hello,

to install a gas or oil heating system in a new building for a technical(!) reason?

not directly technical but there are reasons: (non-)availability of heat pumps and price. Many general contractors have in the past charged absurd markups on heat pumps, but even if they simply pass on the additional costs fairly, that quickly amounts to 5-8 k€. With currently still fairly similar prices for heat generation (10-12 cents for gas and 30-35 cents for electricity with a coefficient of performance of about 3-3.5), you won’t make back the extra cost in your lifetime.

In addition, many people have, not without reason, "fear" or at least concerns about heat pumps. The news and also this forum are full of reports about problems with heat pumps, incorrect sizing, crazy electricity consumption due to wrong sizing, or premature failure of some expensive heat pump components. And considering that there are still many more gas heating systems in operation than heat pumps and you hardly hear about problems there, I can’t blame people for these concerns. They are completely justified.

Currently, as a heat pump owner, you are still forced to thoroughly educate yourself on the subject and bring yourself to a level of knowledge that actually the installer should have, and then afterwards correct his botched work as best as possible and get the system running properly. Very many heat pump installations are botched makeshift solutions by overwhelmed installers. And for that, you’re supposed to pay significantly more than for a gas heating system?

Yes, I can definitely understand that people don’t want that and simply can’t do it.

There are also problems like the fact that people just don’t want a noisy air-to-water heat pump in their garden. If you really enforced noise protection regulations strictly, you could shut down at least every second air-to-water heat pump immediately. And boreholes for brine-water heat pumps are blocked by some water protection authorities or monument preservers. Crazy!

The heat pump is the future and it is urgently necessary to strive to spread them further. The economic viability analysis will also increasingly shift in favor of the heat pump in the future.
But when you look at the trade "heating + installation + commissioning + CORRECT adjustment," heat pumps are often still very, very far from what people are used to with gas heating and expect for their money.
And since among all heating specialists the absolute gold rush has obviously broken out now, I have very little hope that this will change. It will probably get worse because customers are now forced to choose heat pumps.

Therefore, even though I myself would clearly install a heat pump today (we built with gas heating in 2016), I can certainly understand if someone now just wants to quickly get a gas heating system. Whether that is a smart idea is another matter.

Best regards,

Andreas

Many people are quite understandably "afraid" or at least have concerns about heat pumps. The news and also this forum are full of reports about problems with HPs, incorrect sizing, crazy power consumption due to wrong sizing, or early failure of some expensive heat pump components. And when you consider that there are still many more gas heating systems in operation than HPs and you hardly read anything about problems there, I can't blame people for these concerns. They are completely justified.

I think the crucial point here is not that the gas heating systems are better adjusted. Rather, that gas heating simply tolerates more errors in sizing. And that with radiators, the hydraulics play a lesser role anyway, because the thermostat does the work.
