ᐅ Installation of a Gas Heating System in New Construction 2023/2024

Hello fellow home builders,

we have started constructing a single-family house. The approved building permit / planning permission includes a gas heating system, which we still want to install.

There are two possible scenarios:

1. What happens if the heating system is installed in October 2023, but the house is only inspected and approved in February 2024?

2. What happens if the heating system is installed in January 2024, and the house is inspected and approved in May 2024?

Both options are difficult to plan for. So far, we do not know whether the construction schedule might be delayed.
I haven't found any information on this. Do you have any further details?

Regards,
robert0815

We also considered the question of gas condensing boiler versus heat pump (new build detached house, currently in shell construction phase).

The additional cost for an air-to-water heat pump from our general contractor is about 5000 Euros (including a small outdoor foundation). With this, we don’t need a chimney or flue and can also save on a gas connection. It’s almost a break-even situation.

For a new build, the cost issue is less relevant to me if you’re already planning underfloor heating. If you’re also planning a photovoltaic system, you at least won’t have electricity costs for domestic hot water during the summer.

Not only in summer, and not only for domestic hot water 🙂

With a 14.4 kWp east-west roof system and a 10 kW battery, on a 195 sqm (2,099 sq ft) house built to KfW 40 standard, our grid feed-in percentages are as follows:

Aug 22: 0.4 %
Sep 22: 3.5 %
Oct 22: 8 %
Nov 22: 41 %
Dec 22: 84 %
Jan 22: 75 %
Feb 22: 42 %
Mar 22: 26 %
Apr 22: 5 %

CO2? Climate change?
Which brings us back to the topic some mentioned: "If heat pumps work so well, then why are they mandated?! Hmm? hmm???"

Exactly. That’s why. Heating an outdoor pool from -5°C (23°F) to 40°C (104°F) – is he serious? We really do have it too good. At least install double glazing around your fancy pool... Unbelievable.

Are 37–40°C (99–104°F) really enough for standard radiators? Report that quickly for a patent; we’ve just discovered new physics!

Sometimes I feel like two different people are using an ACC. The amount of nonsense you write in between is really strange.

A movable Plexiglas conservatory from Vöroka is planned.
The “we have it too good” argument sounds more like envy to me; otherwise, we would also have to condemn and ban SUVs, koi fish tanks, and campers that consume 20 liters per 100 km (12 mpg) and get upset about them.
I say: to each their own pleasure. And I mean that seriously. Oh, and by the way, I regularly drive at 260 km/h (160 mph) on the highway *duck and run*

Of course: everyone should bear the actual costs for it. But it is supposed to happen 🙂
