MH_Wohnbau22 Dec 2017 09:36Hello, we have made some progress in the meantime, meaning the floor plan is finalized as well as the general contractor.
It will be a single-story (required by the zoning plan) detached single-family house, KfW 55 standard, built on a slope with a large garage and a basement with living space. Living area is approximately 165 sqm (1,776 sq ft).
The floor plan is split-level.
I now have several questions regarding the further planning. Which systems and manufacturers do you recommend (price-performance ratio, advantages/disadvantages)?
- From when is KNX worthwhile?
(We want dimmable recessed LED spots, partially electric blinds / partially roller shutters)
- Central controlled ventilation system with gas condensing boiler (gas connection available / no gas stove desired, possibly a gas-operated fireplace), underfloor heating, possibly additional solar for hot water
- Water softening system

Gas boiler: We have a Junkers unit. The menu system is simple, modeled after Android. It’s well designed.
Smart home: Honestly, that’s just gimmicky stuff. Dimmable LEDs are available at IKEA. We have them in the kitchen. They work perfectly with a small remote control.
Bathroom: A matter of personal taste. They all make good ceramics. We have Duravit. But that doesn’t mean others are bad.
Kitchen: Feel free to check IKEA and get a quote. You’ll be surprised at the good price. We are happy with ours.
Floor coverings: As residents of Schleswig-Holstein, we naturally buy locally: project floors with a 0.3mm (0.01 inch) wear layer, vinyl planks. 19.00 per square meter (approx. 1.77 per square foot). Flawless.
Interior doors: Our builder recommended Jeld-Wen. I’m satisfied. They feel very high quality.
Window profiles: I know Veka, Schüco, Rehau. For me, there’s no difference. Veka is good, and so are the others.

So, if you want to stick with gas, two things are important:
1. The heating engineer must be familiar with the system, and
2. The minimum modulation level must be as low as possible. Modern houses have a very low heating demand, and to prevent the heating system from constantly switching on and off, a low minimum output is better.

We have made some progress by now, meaning the floor plan is finalized along with the general contractor. Oh, did you secretly plan that without us?
Which one of the three candidates did you choose in the end, or was it someone else?

with large open garage What does that mean exactly: an open space without partitions, for cars, garden tools, and trash bins?

The floor plan is a split-level. I hope it has a shed roof? – please show us...
Split-level KfW55 sounds very interesting.

- from when is KNX worthwhile? When it comes to home automation at any level, I tend to avoid committing to any proprietary bus systems. Instead, I prefer to install multi-core cables everywhere in a star topology.

Window profiles: I know VEKA, Schüco, rehau. For me, there is no difference. All equally good. If you definitely want PVC, I would lean toward Gealan, as they also offer coated profiles in various colors instead of just foil-covered.

Modern houses have very low heating demand, so to prevent the heating system from constantly turning on and off, a low minimum output is better. Does that primarily protect the control electronics, or how much does it actually affect energy consumption?

I cannot provide a reliable estimate of the consumption, but I would rather consider it to be low. However, frequent starting naturally increases the wear of nowadays unfortunately more sensitive components. Modern boilers are designed to run continuously at the lowest setting, unlike older oil boilers, which were built for frequent start/stop operation.
