I think there are many factors to consider when choosing the right heating or cooling system for a particular application. Efficiency and energy costs are certainly important aspects, but reliability and maintenance intervals also play a major role.
I personally prefer heating systems based on renewable energy, such as heat pumps or solar thermal. Regarding cooling systems, I think adiabatic cooling systems are a good option as they use very little energy and are also very environmentally friendly.
What do you think? Have you already had experience with different heating or cooling systems? Which system do you prefer for which applications?
I'm looking forward to your opinions and testimonials.
