Storage water heater design 6L, 10L, 15L, 25L
Background
- The market is flooded with low-cost products from unorganized or local manufacturers, making it challenging for branded players to compete on price while maintaining quality.
- Many regions in India face hard water issues, which increase demand for durable, anti-scaling components, raising production costs.
Challenge
- Consumer preferences vary widely across regions due to differences in aesthetic preferences, climate, water quality and electricity infrastructure.
- Ensuring compliance with strict energy efficiency standards and labeling requirements (like BEE star ratings) while keeping products affordable is a significant challenge.
- Transitioning to sustainable and smart products while maintaining affordability.
Solution
- Optimized the thickness of Polyurethane Foam (PUF) insulation led to significant benefits, as it directly impacts thermal performance, cost efficiency, and product lifespan.
- Commonized major number of internal parts & assemblies with an existing water heater model.
- Commonised Service panel sub assemblies for 10L and 15L capacities.
- Commonization of mould between analogue and digital variants with the help of sub inserts.
Impact
- Significant saving in tool cost with commonized parts and moulds between the variants.
- The product exceeds the regulatory energy efficiency standards at 8% margin, which secured the 5-star rating for the next cycle.
- Reduced 50 grams of PUF per unit made a significant impact on the sustainability aspect which helps to attract more environmentally conscious consumers.
