The DTI commissioned a 2 year monitoring programme of four domestic properties with solar installations throughout the UK (including Scotland). The results showed that the systems provided an average of about 70% of the hot water requirement for these properties. This included the winter months of December and January about 17% of hot was provided by solar, whilst in mid summer the systems provided 100% of the hot water, giving an average for the year of 70%. The other 30% is made up from your conventional water heating.

FREE HOT WATER!
Why not install a larger hot water cylinder and be sure that however much hot water you use during the day, there is always more free hot water to come. Perhaps it will make the prospect of a hot water tub in the garden that more realistic.
Is my property suitable?
Preferably you will need 3 square meters of southeast to southwest facing roof receiving direct sunlight for the main part of the day. You will also need space to locate a water tank if required.
