One of the UK‚s leading suppliers of high efficiency gas-fired boilers and water heaters for commercial and industrial applications, Lochinvar, has launched the TT range of high efficiency condensing water heaters and boilers. Available as a heating boiler, or as a dedicated direct gas-fired water heater, twin modulating pre-mix burners and a triple pass heat exchanger are the design principles of this product which operates at efficiencies of up to 97 per cent (gross). In addition, the wide range of control options available provides real potential to reduce fuel consumption and consequently carbon emissions and fuel bills. Low NOx emissions make the new TT range a more environmentally friendly choice.
