Hello,
I'm back again.
Yesterday, we signed the purchase contract for a new build condominium.
The house will have a brine-to-water geothermal heat pump, and all apartments will be equipped with underfloor heating.
A controlled mechanical ventilation system with heat recovery was recommended to us. I’ve done some research, but aside from improved ventilation, is the heat recovery really that effective, and does it fit well with the geothermal heat pump?
I haven’t seen the cost estimate details yet, but the developer mentioned a price of 12,000 euros. I personally think that’s a bit high.
Is that a realistic price?
Best regards

Hello,
I completely agree with Perlenmann. The economic benefits are questionable, but the comfort is excellent. For example, kitchen odors are almost completely eliminated after just 15 minutes on the highest setting, as is the steam after showering or bathing.
Another advantage: on the humid days recently, I set the ventilation to exhaust mode (we are not allergy sufferers), tilted the windows in the children's rooms and bedrooms, and the cool night air was gently drawn inside. It’s an affordable little air conditioner that will definitely work well with the cooling function of the ground-source heat pump in the right summer (we haven’t tested that yet—this will be our first summer in the new house).
Conclusion: In my opinion, controlled mechanical ventilation with heat recovery should definitely be part of a new build.

that sounds good.
Since my architect hasn’t gotten back to me yet, I’m currently looking into systems myself. In the process, I came across decentralized mechanical ventilation with heat recovery. If my architect can’t or won’t offer us a cheaper alternative to a central mechanical ventilation with heat recovery, at first glance, this wouldn’t be a bad option either. Let’s see how things develop.
After all the positive experiences shared here, I would of course like to have one as well. I’m also affected by birch pollen allergies.

JH-CADArchitekt5 Jul 2012 10:19The ventilation system costing €12,000 (approximately $13,000) is acceptable depending on the device:
- €2,000 (about $2,200) plate heat exchanger / old model €4,000 (about $4,400) rotary heat exchanger
- €2,000 (about $2,200) earth collector intake
- €2,500–€4,500 (about $2,700–$5,000) duct materials / valves / silencers
Plus 40% installation costs
Ventilation is a health-related aspect, not an economic one! So, purely financially, it won’t really pay off—except with a ventilation heating system, where you can make back €25,000 (about $27,500) by avoiding a geothermal heat pump system with underfloor heating.
However, you will then need a passive house; otherwise, the ventilation heating alone won’t be sufficient. I would also recommend this option instead of the expensive geothermal heat pump and underfloor heating. It is significantly more worthwhile.
