Wow! That is quite impressive - a drop in consumption from 5000kWh to 3000kWh. The impact you've experienced is quite remarkable. And cost of heating during winter being just under 50 Euros is something really bank-worthy too. I guess a lot of African countries need to learn a lot about energy generation and distribution from Romania then.

I'm guessing though that African regions like West Africa and some other countries where energy generation remains a huge problem, would struggle with the adoption of the system. Apart from the fact that most West African countries experience a relatively constant hot climate, there is still a huge challenge of energy and power generation in the region.
Thanks for the further explanation, I now grasp the scope too. Good to know that water vapour evacuation is a part of the system too.
