Design Technology International worked closely with Heatrae Sadia's engineering and marketing teams to define design strategies that would maximize return on investment. The energy saving benefits of instant boiling water dispensers over kettles are considerable. The time taken to prepare hot drinks is significantly reduced and the water is kept at a constant temperature above 96°. Simplicity of use, ease of cleaning and safety of operation were identified as key issues to be addressed at the design stage.

Careful selection of casework materials allowed the internal boiling water chassis assembly to be clad in stainless steel for the catering market and heat resistant plastic for the commercial and domestic markets. A central escutcheon feature containing all controls and indicators was used to create a common brand image between all products in the range. The fascia was designed to allow the casework to be removed without the need to drain the system - dramatically reducing downtime and service call out costs.

Extensive use of CAD modelling and CAD data transfer allowed design timescales to be minimised and a range of five products brought to market as quickly as possible.
