heat pump Water heater has entered the air source era

Air source water heater also called heat pump water heater 
Air source water heater is called the fourth generation of water heater after the gas water heater, electric water heater, and solar water heater. It uses heat pump technology to absorb heat from the air to transfer heat to the water. So it is also called heat pump water heater. Compared to traditional water heaters to heat same water heated to same temperature, the energy consumption of air source water heater is only about 1/4 of electric water heater. At the same time it can eradicate hazard of harmful gas produced when using gas water heater. Water and electricity are isolated. it’s safety to save a new generation of energy efficient environmentally friendly water heater.
 
Compared with solar water heater, air source heat pump water heater is more energy efficient. In climate environment, the solar water heater directly affected by sun light, it can only rely on electric auxiliary heating when it is sunny and storaged water is not enough. To heat same amount of water, its power consumption is more than air source heat pump water heater. Air source heat pump water heater installation is without location restriction can make flexible design according requirements.

air source heat pump water heater to replace an electric water heater
Based on air source heat pump water heater’s features of energy saving, environmentally and convenient, many experts and enterprises expressed their optimistic about its prospects. Experts estimated if an air source heat pump water heater to be used to replace an electric water heater. It can save 825 kWh of electricity in one year which can be used for three months for an ordinary household. At present there are about 130 million sets of water heaters in country of which about 40 million units of electric water heaters are with power consumption about 67 billion degrees per year. As long as 10% of the electric water heaters are replaced, it can save 3.3 billion kWh of electricity in one year, equivalent to 1.29 million tons of standard coal or two medium-sized coal mine annual production.   
 
However, the current price of a domestic air source heat pump water heater is 5000-7000RMB, much higher than the psychological price of 2000-3000RMB for target consumer group. For the comprehensive promotion of air source heat pump water heater, at present it still lacks policy support of government in China. In Japan, Australia and other countries, government support is an important reason for the rapid development of the industry. Experts called for implement energy-saving tax incentives for manufacturers of air source heat pump water heater or offering electricity price concessions.
