Our Western Sydney customers love this unit because it solves the stressful issue of cold showers during peak morning routines.

Additionally, the smart dual-element setup runs economically on low-cost off-peak tariffs while providing a rapid heating boost when storage levels drop. This system is perfect for very large families, multi-generational homes, or busy commercial washrooms in Seven Hills and Mount Druitt.
Smart Features of the Rheem 400 Litre Twin Element Electric Hot Water Heater
This robust water heater packs elite thermal engineering into an incredibly durable, extra-large cylinder. It features a heavy-duty Rheemite vitreous enamel lining to protect the inner tank against harsh minerals and corrosion. Furthermore, the versatile tank design provides dual-side plumbing connections on both the left and right sides in Western Sydney. This practical feature allows our technicians to replace your existing hot water system quickly without major pipe re-routing.
Because of its substantial physical footprint, you can position this heavy-duty model in several convenient locations. It measures 1840mm high, 690mm wide, and 735mm deep. Therefore, it sits comfortably on an outdoor concrete slab or matches perfectly inside a spacious laundry room or utility closet. Families in Mount Druitt and Seven Hills choose this unit to secure strong, mains-pressure hot water to several showers at the same time. Consequently, you enjoy consistent household comfort and reliable hot water recovery throughout the year.
