"Reduce to a minimum" is the design maxim for the new Vitotec range of wall mounted boilers. Its declared aim is the optimum integration into the living space. The generosity and clarity of its single unit cover and its sturdy control interface, covered by a protective full-sized flap, create an overall pleasing architectural design. The cover over the control interface provides an ergonomically shaped grip acting as release and opening mechanism in one. The standard design of control functions, the repeating design elements in the control area and the uniformity of the company's appearance in the market place create a formal identity for the entire produce range, assisting orientation and encouraging trust.
