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

Hopefully, you won’t have to wait for years if nobody signs.
Don’t you have a financing arrangement where you would eventually have to pay commitment fees?

We calculated the financing carefully; we only need a bridging loan because we will be selling our current condominium. Still, I do have some concerns about whether everything will work out. A friend of ours had quite a lot of trouble—selling her house and moving into a new build went so wrong that she ended up with higher costs and had to sell her house for less in order to cover the financing.

Hello,
we have now been living in our single-family home for 6 months and we no longer want to do without the controlled residential ventilation system. The house always smells fresh. You don’t even notice the airflow. In summer, you don’t have to open the windows and let the heat in. The house is always cool, yet you have fresh air.
Enjoy your future home!

Micha&Dany19 Jun 2012 06:59I can’t yet assess how the indoor climate will be with mechanical ventilation with heat recovery. But I currently live in a rental apartment that was insulated with 20cm (8 inches) of insulation two years ago. Since then, it feels like we’re living in a plastic bag. We have to keep the windows open all the time – even in winter. The insulation didn’t help us save on heating costs…
That’s why, for me, mechanical ventilation with heat recovery is the only option for modern, well-insulated houses!

sevenofnine19 Jun 2012 08:39Hello, thank you for all your responses.
The developer has not gotten back to me yet. I have now contacted several other providers and am curious to see what comes of it.
I don’t think I will be able to ventilate properly, as the developer suggested. Besides, the ground source heat pump would probably be pointless if you’re trying to save energy on one hand but wasting it by letting air escape through the windows on the other.

perlenmann19 Jun 2012 21:14Energy savings from a controlled residential ventilation system are not really the main point. Such a system also requires electricity and has about a 90% efficiency rate… well, numbers on paper don’t tell the whole story. The real benefit of a controlled ventilation system lies in the comfort it provides. In other words, you will probably never recover the costs of a controlled ventilation system through energy savings alone.
However, having constant fresh air, no cold drafts, and no fogged-up windows might make it worth it.
