Sheffield’s Northern General Hospital has ‘significantly improved’ the efficiency of its new low pressure hot water heating system by installing 30 BoilerMagXT units from Eclipse Magnetics.
BoilerMagXT’s ability to remove black iron oxide or magnetite (sludge) reportedly delivers efficiencies of around 6%, reducing CO2 emissions, and ‘eliminating blockages, wear, and boiler breakdowns’. The company said: “The BoilerMag range of filters offers one of the most effective methods of removing ferrous and nonferrous contaminants, down to sub-micron size. As water circulates through the core, Eclipse’s high intensity magnets attract iron oxide contamination to the magnetic rods, removing it from circulation.”
The Estates Department at the Northern General Hospital specified BoilerMagXT as part of a steam to low pressure hot water conversion scheme. Other energy efficiency improvements on the 120-acre site include new gas condensing boilers expected to be some 10-12% more efficient than the site’s ‘outdated’ conventional existing boilers. Magnetic filters were specified for additional protection to new plate heat exchangers; the previous system had regularly became ‘clogged’.
