Hello everyone, I'm Luca and I write from Rome, Italy. I'm new to the forum and am looking for help in solving a problem.
Thank you in advance who will want to help me out
))
So, I'm building a greenhouse for cacti and other succulents, the topic is how to heat in winter the greenhouse using solar panels and a boiler or solar water heater.

I know the basics of an electrical system, I can manage a little with the water pipes, I work with wood, I use a welder, but I'm not an expert in renewable energy, I have only approximate ideas, but I definitely want to finish my project. the more so that it begins to get cold
And I must premise that my goal is not to go below 8 degrees at night, but also during the day if the temperature drops just below 8 °.
Here is the description of my idea:
-1. I want to make an underfloor heating system, then put in the greenhouse floor (which is simply a dirt surface) a tube (the green plastic that is used for plumbing in the house), buried approximately 5 cm, placed as a serpentine.
Hot water passes into the pipe and heats the ground and the greenhouse. You can see it in photo 2.

-2. The heating must start when the thermometer detects a decrease of the temperature below 8 °, then it takes a temperature sensor, unless it is too complicated, and then solving with a timer.
-3. The greenhouse measures 18 meters x 8 meters x 3.80 h, is covered with a PVC sheet, not dual layer. During the winter the doors are closed.
-4. The greenhouse is located in Rome, Italy, then the temperature is mild, but in the months of January and February can reach 0 to -2/-4 or down at night, and even more.
-5. I do not want to use a hot air burner fueled by diesel.
-6. I understand that solar energy systems can be of two types: isolated, and there is no need of batteries or connected to the mains supply: here is to understand what is most suitable for my purpose, taking into account that I could also create a paneling, say, 6 meters x 8 meters, so as to have electricity for other purposes.
7. There to understand even if the system is closed-loop or not, and if it is a closed circle maybe it takes a pump
ok, this should be exhaustive, I expect your suggestions!
a warm greeting to all the forum community!
