Product details

A heat pump water heater is an energy-efficient system that absorbs thermal energy from the surrounding air to heat water, using up to 70% less electricity than a traditional electric geyser. How It Works • Evaporator: A fan draws ambient air across coils containing a liquid refrigerant, which absorbs the heat and turns into a gas. • Compressor: The refrigerant gas is compressed, which dramatically raises its temperature and pressure. • Condenser: The hot refrigerant passes through coils inside or wrapped around the water tank, transferring heat to the water. • Expansion Valve: The refrigerant cools, drops in pressure, and cycles back to absorb more heat. • Backup Element: Most units include an electric resistance backup element for rapid heating or very cold ambient conditions. Key Advantages & Specs • Coefficient of Performance (COP): Typically ranges from 3.0 to 4.4 (300% to 440% efficiency), delivering 3 to 4.5 units of heat energy for every 1 unit of electricity consumed. • Weather & Time Independence: Unlike solar water heaters, heat pumps work 24/7, including during monsoons, cloudy days, or nighttime. • Lifespan: Lasts 15 to 20 years with proper maintenance (longer than the 8–10 year lifespan of a standard geyser). • Noise Level: Operates quietly between 40 to 55 dB (similar to a ceiling fan)
