ᐅ How much did you pay for your mechanical ventilation system with heat recovery?

I’m currently a bit uncertain about what a balanced mechanical ventilation system with heat recovery should realistically cost. Two different suppliers offered quotes for the exact same floor plan, and one came in at 8,500 EUR while the other quoted 13,000 EUR. Could it be that Supplier A forgot to include a lot of important components? What have you paid for your balanced ventilation system, and what was included—such as sufficient sound attenuators, preheating coils, ground-source heat exchangers, enthalpy exchangers, and other optional features?
A 53% price difference is quite significant.

Wolf CWL 300 with a simple heat recovery exchanger without pre-/reheating coils or any other air treatment, using Helios flat ducts integrated into the insulation of the ground floor ceiling/wall outlets and upper floor floor/wall outlets.
In total 4 exhaust air and 5 supply air outlets... 2 silencers on the unit and a condensate drain...
Approximately 7,000 including installation, however in 2011.
