Since then, the range has expanded to incorporate 39 different model options, in outputs ranging from 12kW to 70kW, and has grown its market position to where almost one in every two boilers installed is a Grant Vortex, claims the company.
The range has gained several accolades during the past few years, including an endorsement by the Energy Savings Trust, and the H&V News Top Product of The Year award in 2003 for the kitchen/utility model. In September 2008, the Vortex Combi model picked up a Which? Best Buy.
Being one of the most reliable and economical boilers available on the market, says the company, the Grant Vortex has a seasonal efficiency of up to 93.3% gross (SAP 2009). “Featuring internal and external, floor standing and wall hung, boiler house, standard, system and combi models, the Vortex utilises a high quality stainless steel heat exchanger with Grant’s exclusive turbulator baffle system, which ensures ultra-high efficiency, low fuel usage and minimal running costs.”
