We ordered a project for a power station for four houses and the installation from the company Ukrainian Energy Systems. The preparation period lasted about a month, with approvals from the city council, installation, and launch taking three days. We managed to get it done before the cold weather set in, and after testing, it looks like this winter will be economical and very warm. It's nice that there is a two-year warranty and we can call to clarify any questions with the managers. So far, only positive emotions.
