Air Source Water Heater

Air Source Heat Pump Water Heater

Is engineered to be used as a renewable energy equipment which uses the heat from the ambient air to heat the water. The heater provides an energy efficient yet affordable source of hot water round-the-clock for every need. Heat Pump Water Heaters are designed for both domestic and commercial hot water requirements.

Working Principal of Heat Pump Water Heater

Major components of a Heat Pump Water Heater include a compressor, a refrigerant, two heat exchangers (a condenser and an evaporator) and an expansion valve.

  • The high temperature gas is cooled in the first heat exchanger (condenser) and loses its heat to the water flowing from a storage tank.
  • The condensed refrigerant then passes through an expansion valve that lowers its pressure.
  • In the second heat exchanger (evaporator) the low pressure refrigerant absorbs heat from the ambient air and boils to a gas.
  • The refrigerant than returns to the compressor and the cycle is repeated in this manner.
  • Heat absorbed from the air is transferred to the water and the heating continues till the desired temperature in reached.

Advantage of Heat Pump Water Heater

  • Very low operating cost – 20% of an Electric Water Heater. Lower running cost than boilers (75% lower) or solar water heaters (25% lower).
  • High energy efficiency – Coefficient of performance (ratio of output power to input power) can be as high as 4.
  • Compact size and ease of installation. Can be installed in any convenient location.
  • Continuous hot water supply – Uninterrupted operation during night time, on rainy days and even on cold days. Works in any kind of weather and all seasons.
  • Can be scaled to meet requirements from individual villas to large commercial installations.
  • Reliable and durable – Can last for years with little or no maintenance.
  • Simple Operation – Temperature and time options can be preset on the intelligent digital controller
