There is no such thing as the best. What matters is what you want
from the system, what your existing systems are and how many
modifications you want to make to your existing systems. Give us a

Solar space heating systems may work for single wooden rooms in some
parts of the world. However, in the UK they will only provide
supplementary heating for some parts of the year in the typical
house.
