The heat pump is running really well, for it to continue to do so, it is important that dirt from the rest of the heating system, does not enter into the system.
Still a large portion of the radiator system is really old, and it is not unusual that there is rust and other impurities in it.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
