'One of Northern Ireland's oldest family businesses is still leading the way in its field with a new invention that is set to revolutionise the global solar water heating industry.

Belfast company Willis Heating & Plumbing CO. Ltd., established by William Willis in 1887, is most famous for the invention of the Willis Immersion Heater which became an essential feature of virtually every household in Northern Ireland during the 1960's & 70's. Now the company, under the leadership of managing director and fourth generation family member John Willis, has developed a new solar water heating system that it claims will be the biggest industry breakthrough since the Willis Immersion Heater - the Willis Solasyphon.'
