ᐅ Is an offer for heating, plumbing, and ventilation really this realistic?

No, unfortunately, those are not included. :-(

Wow, that really is a significant amount. As I said, our costs are similar overall, but about 16,000 for plumbing fixtures are included in that. Like matte1987, we will probably provide the sanitary fixtures ourselves, but for comparison’s sake, we had everything quoted first. Supplying the fixtures ourselves would cost around 9,000 just to give you an idea of the “wholesale” price expectations from the supplier.

I find Zaba’s sanitary fittings quite aggressively priced: 4,600 gross for “official,” meaning “non-internet” prices, which is ambitious. Even better if it actually works out that way.

Otherwise, I think the heating system is acceptable, but the mechanical ventilation with heat recovery is way too expensive given that it doesn’t include the heat recovery unit. Of course, Vallox probably charges a premium for its brand compared to other manufacturers. Just for comparison: our Zehnder ComfoAir Q350 is close to 12,000 – with KNX interface and Tecanno 125 ceiling-mounted supply and exhaust air vents.

Our bids ranged between 60,000 and 66,000 (gross), each including Alpha Innotec – no one wanted to offer the Ochsner unit we requested, no idea why. However, statements are promised on why the Ochsner is not offered. Otherwise, Novelan and Alpha Innotec are comparable; if I remember correctly, the hardware in Novelan units also comes from Alpha Innotec.

I’m curious to see what other bids you get. Fingers crossed that the price can come down a bit.

If I add those costs on top, the heating system and so on already costs me almost as much as my shell construction.

Then you got a good deal on the shell construction. For this scale, under 100,000 nowadays is already a good price.

We were also shocked...

Why? That’s a reasonable price for a brine-to-water heat pump. The drilling alone costs around 15,000 (approx. 16,500 US dollars)... at least here in our area (offer from December 2017)... and a freestanding bathtub is definitely not a budget saver either...
If I roughly calculate (assuming gross prices):
65,000 minus drilling: 50,000
10,000 for controlled mechanical ventilation: 60,000
3,000 for the bathtub: 57,000 => certainly not a bargain, but quite acceptable.

Wow, that’s really quite something. As I said, our costs are similar, but include about 16,000 (USD) worth of sanitary fixtures. Like matte1987, we will probably supply the sanitary fittings ourselves, but for comparison purposes, we first obtained full offers. Just to give an idea of the price expectations from the "pharmacy wholesale" side: the turnkey sanitary fixtures are around 9,000 (USD).

I find Zaba’s sanitary equipment surprisingly affordable: 4,600 gross for "official," meaning "non-Internet" prices, is ambitious. Even better if you can make it work with that.

Otherwise, I think the heating system is fine, but the mechanical ventilation with heat recovery (MVHR) seems way too expensive considering it doesn’t have an enthalpy heat exchanger. Of course, Vallox probably charges a premium for their brand compared to other manufacturers. For comparison: our Zehnder ComfoAir Q350 costs just under 12,000 (USD) – including KNX interface and Tecanno 125 flush-mounted supply and exhaust air vents.

Our quotes ranged between 60,000 and 66,000 gross, all including Alpha Innotec units – no one was willing to offer the Ochsner system we wanted, no idea why. We have had commitments to provide explanations on why Ochsner isn’t offered. Otherwise, Novelan and Alpha Innotec are comparable; I think actually Novelan’s hardware is from Alpha Innotec, if I remember correctly. Construction site: Middle Franconia.

You were lucky with the shell construction costs. For a budget under 100,000 it’s a good price nowadays.

The 4,600 gross will be removed and replaced with better sanitary equipment. Fortunately, not everyone likes tiled showers or concealed fittings. We both consider rain showers to be a waste of money. Still, I estimate around 10,000 gross for sanitary fittings alone.

Plus shower enclosures costing x (USD).

Thank you in advance for your feedback. I will keep you updated regarding the following quotes.

I honestly don’t know what I’m doing wrong… (maybe this doctoral thesis on the specifications from my HVAC planner is partly to blame)

Quote in Baden-Württemberg:

Heating:
- Vaillant gas system combined with 3 solar collectors €20,200
- Fixtures and accessories €4,700
- Piping and accessories €5,100
- Underfloor heating (200sqm (2,150 sq ft)) and accessories €15,200
- Radiators and accessories €2,600
- Thermal insulation and accessories €2,000
Total heating approx. €49,000

Sanitary and ventilation:
- Drainage inside the building €8,500
- Irrigation system €14,300
- Pipe insulation €2,100
- Sanitary installations for 3 bathrooms €22,400
- Geberit GIS system €6,700 (too expensive for me… I plan to dismiss the architect and do it conventionally)
- Exhaust system with supply air overrun €3,800
Total sanitary and ventilation approx. €58,000

I find all of this, especially compared to what I’ve read here, very expensive for a 200sqm (2,150 sq ft) house without a lot of extras. That’s about 20% of the total building costs. The architect had planned about 13% at €58,000.

However, some of the company quotes are quite surprising… including one that matched the HVAC planner’s cost estimate with around 700 items at 100.00% accuracy!!!

In the meantime, I have already removed a cistern, the GIS system, and things like a lift station (not necessary), and I have made the kids’ bathroom optional (can be added in a few years).

Very expensive is good. This is madness!
You pay €107,000 for heating/ventilation/plumbing, and that doesn’t even include a central ventilation system.

I think I’m going crazy...
