The history of ROTEX heating systems is marked by numerous innovative products and developments. Founded in 1973 as a plastics processor, ROTEX GmbH started producing heating oil storage tanks made of polyethylene (PE) in 1978. The company succeeded in quickly claiming a leading position on the market in this sector.
With new product groups – from underfloor heating and hot water storage tanks right up to solar technology – ROTEX continued to achieve further developments in heating and household technology. With the development of the pioneering ROTEX A1 boiler series in 1996, the company offers a complete product line of boiler/burner combinations with gas and oil condensing boiler technology.
Today ROTEX sees itself as a provider of complete, innovative and environmentally friendly heating systems. With the ROTEX EcoHybrid, the company provides a complete system that covers all areas of heating (heat generation, water heating and distribution as well as heating oil storage). All components are technically sophisticated, carefully adapted to one another and processed in high quality.
The company's portfolio includes air/water heat pumps, condensing boilers for oil and gas, solar systems, hot water storage tanks, underfloor heating, heating oil storage tanks, rainwater storage tanks and a connective installation system for sanitary and heating facilities.
On 1 October 2008, ROTEX Heating Systems GmbH became a 100% subsidiary of Daikin Europe N.V. (Oostende/Belgium). DAIKIN Europe is a subsidiary of Daikin Industries Ltd., a listed company domiciled in Osaka, Japan, with approximately 60,000 employees worldwide.
