The Freshwater Biological Association (FBA) has had a  base at Far Sawrey on the shore of Lake Windermere  for decades. This used to be their main office and  laboratory, sitting alongside holiday accommodation.

Many years ago, they installed a central biomass heating system that supplied heat to the whole site. When it needed removed the FBA consulted an independent energy advisor to get impartial, clear and objective advice on what heating system to replace it.

"The FBA aims to become as carbon neutral as possible; this was an important consideration in deciding on the new heating system."
