Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.
Dulas
Dulas or City Dulas is a town in Anglesey, in north-west Wales. It is located on the A5025 road, near the coastline (Dulas Bay) at only 5 metres (16 feet) above water level. The town has never held the standing of a city and "City" is not a recognisable Welsh word, so its beginning is uncertain. It may be that the name came from an Anglicisation of Saith Ty, which is Welsh for "Seven Houses". There are two areas in Wales simply called 'City': City, Powys and City, Vale of Glamorgan.
