In the News: Roger Bisby appraises the Super S water heater
Manufactured from Duplex stainless steel and offered with a 25 year guarantee, the OSO Super S was recently reviewed by Roger Bisby of "Professional Heating and Plumbing Installer" magazine. Roger concluded "Now that's what I call innovation. I have never fitted an indirect cylinder as easy as this." (PHPI July/Aug 2009) Read Roger's article here. (Please note Roger was fitting the original version of the Super S that was supplied with a separate expansion vessel. New cylinders offer substantial further space and labour savings with factory fitted under-lid vessels.)
