Stiebel Eltron WWK 302H Hot Water Heat Pump 302L - Premium Energy-Efficient Heating for New Zealand Homes

Upgrade your home's hot water system and slash your power bills with the Stiebel Eltron WWK 302H Hot Water Heat Pump (302L). Engineered in Germany and optimized for New Zealand climate conditions, this trade-quality hot water cylinder sets a new benchmark for energy efficiency. By harvesting heat from the ambient air, it delivers up to a 74% saving on hot water energy use compared to traditional electric water heaters, making it one of the smartest upgrades you can make to your property.

Designed to easily handle the hot water demands of busy Kiwi families, the WWK 302H features an intelligent 1.7 kW smart element in the top of the cylinder. When a high volume of hot water is drawn off, the smart element automatically activates alongside the heat pump to rapidly recover the top 80 litres of the tank. This ensures your household never runs cold, even during peak-use times.
