Biocurve manufactures condensing biomass boilers for central heating and hot water systems for domestic users. Development of a virtual model of the current 25 kW boiler model in which the number of pipes has been reduced from ten to three. The reduction of the number of pipes in this model represents a saving of 18 kg of stainless steel (a 32% of the original weight of the pipes of this boiler). This lower number of pipes implies savings of raw material, but also, savings in fabrication costs (lower hours of workforce required, smaller insulation needed, less paint) and transport costs (lower volume of the boiler). The total cost saved estimated for this model is around 400 € per unit.
