Hi, we live in Petrer/Alicante and bought 3 years ago a new house. The solar panel with 150 liter water tank (for 2 persons) was installed by a local company 2 years ago and we don’t want to miss it anymore. Throughout spring to autumn we enjoy hot water exclusively from the solar panel.
At the moment we are having a new gas central heating system installed and the solar panel is connected to the system so any hot water that is produced during winter will help heating the water which goes to the taps.
It is a definite “YES, go for it” :-).
