Hello construction experts and enthusiasts, I have been reading along for a while and now I need some advice.

We want to build with TuC here in Saxony, postal code area 02.
The companies that build for TuC here have a good reputation and there is a lot of building activity at the moment.

Most people simply build an affordable house, called Standard eco Baustein 1. Unfortunately, posting links is not allowed. We want to make a few small changes if they make sense.

We would like to increase the exterior wall thickness from 24cm (9.5 inches) to 36.5cm (14 inches), using aerated concrete from Porit in monolithic construction.
The additional cost is about 7,300€ (the foundation slab will also be larger to maintain the living space). The rest will be adjusted to the stronger walls – roof, windowsills, etc.

If worthwhile, we would replace the gas condensing boiler with an air-to-water heat pump (Vaillant aroTherm Split vwl 75/5) with Unitower vwl 78/5 IS.
Additional cost: 6,000€.

Underfloor heating throughout the house.
The house model is Flair 125, where 125 stands for the square meters.
One and a half stories.

What are your thoughts on this?

Kind regards,
Kobi

We had our fan motor connected to a light switch.

Is it possible to adjust the ventilation yourself, for example to keep it running when leaving the house? Or does it have to be done by a plumber?

You can control the Lunos units using a switch:




or with a control panel:



or even through a web browser, depending on your choice and how advanced you want the control to be.

In the Town & Country standard, there are two switches in the utility room as shown above. The ground floor and upper floor can be controlled separately with levels 1/2/3, and the bathroom fans can also be set to full power, for example, after showering or to eliminate odors.

We just received a rough estimate for the gas connection from a homeowner opposite us; I believe they are going with a heat pump...

Base price €1485
€130 per meter (including public works with civil engineering) (approximately 40m (130 feet) distance, not on site) which totals around €5200.
Then the meters on the property up to the house will be added.
On private property: paved €50 per meter (I assume this includes paving and restoration).
Unpaved €6 per meter (likely applies to us since there is nothing existing, just trenching and refilling).
We still need about 20m (65 feet) on our property.

Phew, way too expensive. They can keep their gas. Here it was 750 all inclusive.
