1. Problems in Heat Pump Water Heater Industry
Scale of Heat Pump Water Heater Industry
The size of the heat pump industry is still relatively small, the leading brand becomes vacant.
First, the sales scale of industry is small. According to the Americana Research Center
forecast, a sale of heat pump water heaters in 2011 was about 16 million, which is much less
than the solar water heaters with the sales volume of nearly 400 million. Second, there has
not been a leading brand in the heat pump industry. Due to the rapid expansion for market
demand, and imperfect industry access system, and various of capitals with the production
capacity of flooded into the market, small scale of the vast majority of air source heat pump
water heater manufacturers, specializing in the production of low levels of market
development not enough, only a few brands have national renown, the sales volume to the
hundreds of millions of businesses has not yet appeared.
Inadequate Policy Support in the Heat Pump Water Heater Industry
Currently, the state has been or is being gradually introduced the considerable subsidy policy
and industrial base policy to encourage the use of solar energy, some local governments
also introduced a number of related policy. However, compared to the solar industry, heat
pump system business has not fully enjoy the preferential fiscal and taxation policies of
energy saving and environmental protection industry, heat pump hot water project users also
do not enjoy subsidies policy, government support policy for the heat pump industry also
cannot be compared with the solar industry.
Technical Level of the Heat Pump Industry Still Need to Be Improved
In recent years, a number of powerful enterprises have attached great importance to the
research and development of technology, also have made gratifying achievements. But,
overall, air source heat pump water heater has not been into China's market for a long time,
industry access system is imperfect, uneven corporate, corporate general R & D investment
is not enough, the product technology level is not high. First, the core components of the heat
pump water heater compressor technology is poor, it is known that there are several
domestic enterprises can provide dedicated compressor heat pump water heater, the vast
majority of enterprises imported from abroad compressor or Use the air conditioning
compressor. Second, t a number of heat pump water heaters have poor heating effect in a
timely manner, and does not solve defrosting problem in a good way, it will cause the frost
phenomenon after entering the winter. Third, the heater tank technology air source heat
pump water is not mature enough, and sometimes causes the tank to burst. Overall, there is
a gap between the technical level of the heat pump water heaters in China and the world,

2. whether it is the level of manufacturing or design process, there is still much room for
improvement.
