Hello,
Two new houses are being built to KfW40+ standard.
I have received the following quotes for the two houses.
The quotes are based on the calculated heating load.
I noticed that only for the mechanical ventilation system the materials are listed separately, so I was only able to check the price for that part.
I quickly and easily found several companies online where the prices are about 25 percent cheaper for me as a private end customer. Now I would like a price assessment for the rest.
I would like to negotiate with the heating installer and confront him with this. He definitely will not be installing the photovoltaic system, as his price is 8,000€ higher than other offers.
The offer is for a building with 3 residential units and a basement; the other quote is similar but for 2 residential units. I actually thought I would get a good price due to synergies since two houses are being built next to each other.
Here are a few examples of the price differences:
Vaillant recoVAIR VAR 360/4 E apartment ventilation device with heat recovery – Heating and solar at discount prices
Price in store 3359€
Price from installer 4464€
Vaillant CO2 air quality sensor – Heating and solar at discount prices
Price in store 325€
Price from installer 411€
Vaillant flexible flat air duct 52 x 132 mm (20 m) – Heating and solar at discount prices
Price in store 199€
Price from installer 252€
By the way, if anyone here can make me a competing offer and is possibly interested in carrying out the work, please feel free to get in touch.
Civil engineering has already started, heating and sanitary installation scheduled for April to May 2022.

I can only share my thoughts on the controlled residential ventilation system. If possible, switch from flat ducting to round ducting. In your offer, flat ducting is priced at 200€ for 20m (approximately 65 feet), whereas privately or through a tradesperson, you can get about 50m (165 feet) for roughly 100–120€.
You or the tradesperson can save money by choosing round ducting.
For example, 1000€ for flat ducting could be 200€ if using round ducting.
I had a similar situation where I could have purchased an AlphaInno heat pump online for 3000€ cheaper, but the installer kept the 3000€ government subsidy for himself. BUT what can you do if you’re not able or supposed to install such equipment yourself? It’s always a question of how far being frugal should go.

the material ...
I quickly and easily found several companies online that offer prices 25 percent lower for me as a private end customer. When I need car replacement parts, I can often get them offline from reputable parts dealers up to 50% cheaper than at the authorized service center. However, you should be able to install these yourself, as most workshops don’t like it when you bring your own parts...

Example Metro, where every average consumer can get it.Believe me, Metro or large retail chains have very little in common structurally with the plumbing trade, so this example doesn’t really fit here. Wholesalers can all match online prices, but the installer is still positioned between them and you. (Sometimes they don’t even communicate with you unless the installer explicitly “allows” it.) The fact that the installer – as shown here – gets paid for installation doesn’t stop them from adding a significant markup on the materials as well – though there are good and bad cases. Our installer – whom I consider one of the good ones – sells you the materials at list price, but everything is then included: installed, finished, and ready to use.O

List price was, for example, 300 € (about 330 USD) during the selection process.
Minus the discount from the plumber, plus installation costs = again roughly 300 € (about 330 USD).

I just thought of an even more extreme example from the automotive sector.
I had a leaking line in the clutch hydraulics of a Nissan.
The replacement part would have cost €60 (about $60) at the Nissan dealer.
I measured the old part...
--> I found an identical hydraulic hose (same length, same diameter, same thread) as a replacement part for the brake system of some motorcycle for €12 (about $12).
80% cheaper, or a 400% markup by authorized service centers—I find that quite extreme!
On the other hand, 25% is still acceptable…

I don’t have a separate installation charge either (unless you count the "site setup," which, for a heating/plumbing contractor, is not very extensive and definitely doesn’t occur just once). The material costs are higher than online prices, but installation and warranty are included in those costs.
