Heat pumps and solar hot water systems are considered more energy efficient because they utilise renewable energy sources and efficient heat transfer methods.
Heat pump systems extract heat from the ambient air using a refrigeration cycle, yielding up to three to four times the energy they consume in electricity, making them significantly more efficient than traditional electric or gas hot water systems.
Solar hot water systems capture sunlight using rooftop solar collectors, providing a sign of a household’s needs depending on the climate. Both systems reduce greenhouse gas emissions and operational costs compared to conventional hot water systems.
