Founded in 1972 in Legnago, Verona, Italy, we have operating divisions in: Italy, Great Britain, Spain and China. Our distributors are all around the world, in markets as diverse as North America, Chile and Australia. In 1973 we were the first company to produce a compact and efficient plate cast iron radiator. We opened our first UK office in 2002 and we have a loyal customer-base of Gas Safe registered heating engineers and homeowners who all testify to the high quality, durability and satisfaction they have with Sime boilers.

With a proven reputation for quality, reliability and performance, our domestic and commercial boilers and accessories incorporate the stylish design and innovative engineering, synonymous with our Italian heritage. Our heating and hot water products are in over three million homes worldwide.

Manufactured using the most advanced production systems and the highest quality brass and stainless steel components, our boilers are compact, lightweight, easy to install and come with 2, 5 and 10 year warranties.

Our commercial boilers offer flexible solutions for buildings of all sizes, and with varying hot water requirements. We work hard with our specifier-contractors to ensure we meet their project specifications, delivery schedule and after sales support.

In 2014, we were the first to offer a hybrid wall hung unit that incorporated a gas boiler, heat pump and MEM control. Environmentally-conscious, we strive to reduce, reuse and recycle wherever possible, and aim to continually improve our environmental performance with not only our production processes, but also with our product design and packaging. This innovation and commitment is part of our DNA and we continually strive to be pro-active in all areas of our business.
