BOILERS:RENEWABLES NU-HEAT LOOKS AT SUPPLEMENTARY BOILERS, VAILLANT EXAMINES HOW BOILER TECHNOLOGY HAS EVOLVED AND MHG HEATING HIGHLIGHTS HOW TO GET THE MAXIMUM IMPACT FROM A HEAT PUMP Vaillant makes improvements to its ecoTEC range Not content with producing the boiler that was awarded 2011 Which? Magazine ‘Best Buy’ status, Vaillant has reengineered the ecoTEC range to incorporate new technologies and features that make it even more efficient, even more economical in operation and easier than ever to install and use. Performance and installation improvements include: a new electronic gas and air modulation system for a cleaner, lower emission combustion; a flame lift detection system for more efficient and quieter combustion; a new higher efficiency pump for reduced energy consumption and lower standby losses; intuitive interface and fault codes; and a new installation wizard for quick installation. With low carbon dioxide emissions, SEDBUK efficiencies of up to 89.4% (SAP 2009) and a NOx class five rating, ecoTEC plus offers high performance.
