Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.
Dulas
Dulas or City Dulas is a town in Anglesey, in north-west Wales. It is situated on the A5025 roadway, near the coastline (Dulas Bay) at just 5 metres (16 ft) over water level. The town has never held the condition of a city and "City" is not a recognisable Welsh word, so its origin is unclear. It may be that the name originated from an Anglicisation of Saith Ty, which is Welsh for "Seven Houses". There are 2 areas in Wales merely called 'City': City, Powys and also City, Vale of Glamorgan.
