Hello everyone,
I would be interested to know what you think of the two ventilation systems or if anyone is using one. Furthermore, I would like to know whether the purchase of a decentralized ventilation system is wasted money and whether the heat exchanger saves significant energy costs that I can include in my investment calculation? Thanks for your contributions.
