Hello,
we have been offered a Stiebel Eltron LWZ 170 for €10,000 for our 120sqm (1,292 sqft) semi-detached house, which is being built according to the 2016 Energy Saving Regulation (KfW 70 standard).
Does anyone have experience with the LWZ 170?
Is this offer reasonable?
Is a Zehnder ComfoAir 350 preferable, and what would the costs be?
Thank you very much!

The main unit itself costs about 2000€. The rest includes the pipes, connectors, and installation effort. 10,000€ is the standard price for a complete ventilation system, including installation and commissioning. We have the ComfoAir 350 but don’t have a comparison to the Stiebel Eltron unit. It’s hard for anyone to provide a genuine comparison since hardly anyone has both devices running at the same time.

A ventilation system circulates air. The circulated air is, of course, clearly audible in the utility room. In the rooms, a slight draft can be heard during the first few weeks, but you get used to it quickly. The ComfoAir system is technologically outdated in terms of control; there is no app control (e.g., programming via tablet), and a successor model is already available. I don’t know how it looks with the Eltron device. Helix is also known as a common ventilation systems company.
The Comfoair 350 is currently my favorite as well; you only read good reviews about it online and it consumes just 20 watts of power at level 1.
It is perfect for programming via tablet, provided you are familiar with Openhab or FHEM (open source home automation).
With this, you can implement all kinds of possible settings:
1. Off or level 1 when away
2. Turn to maximum at higher humidity levels
3. Turn the system off when a window is opened
...and so on.

We run our ComfoAir 365 days a year on setting 2 at just under 40 watts. On setting 1, as correctly mentioned, it’s just under 20 watts. Despite being a tech enthusiast, I don’t bother with any outdated connection technology. I’d rather program it quickly on the less-than-ideal control panel. You only do that about once anyway. There are wireless buttons available that let you switch to full power with a single press in the bathroom (or elsewhere) for a fixed time (I believe 30 minutes). However, we don’t have those.
As mentioned, there is already a successor model. Maybe check their website for more information.
