How long has Glen Dimplex been in Ireland?

When Martin Naughton founded Glen Electric in 1973 he was just an engineer with a great business idea. By the time he bought Dimplex in 1977 – a company eight times the size of Glen Electric – he was already a businessman with a truly international vision. Since then, the Glen Dimplex Group has grown steadily and enjoyed great international success. The headquarters in Dublin has a staff of 200.

What customers and markets does the Glen Dimplex Group serve?

What began with a handful of people more than forty years ago is now the world’s largest manufacturer of electric heaters and generates an annual turnover of EUR 2 billion. To this day, the Glen Dimplex Group is owned and run by the Naughton family. Some 4,000 employees around the world are busy making the planet cleaner and more environmentally friendly – with intelligent electric heating, cooling and ventilation systems.
