Solar thermal maintenance should include an annual inspection, fluid checks every three to five years, and prompt attention to pressure or pump faults.
Solar water heating cost in the UK runs from £4,000 to £7,000 for most homes, with savings of £50 to £120 per year depending on your current heating fuel.
Solar thermal collects heat for hot water while solar PV generates electricity. Both use sunlight differently and suit different household energy needs.
