Wotech heat pump compares with Solar heating.

	Solar power feature	Wotech air source heat pump feature
Energy saving	Use for free when the sunlight is strong. Assit heating when it rains or the sunlight temperature is low. Use electricity to heat at least 120 days all the year round, amounting to 500 days power consumption madeby air power heat pump set.	Average efficiency is 460%. The operation fee is low for a year, just amounting to 65% of solar power system.
Safety	Electricity is set in water. It has the danger of leakage, drying out etc.	Separate water and electricity prevent leakage, etc.
Steady	Scaling happens easily in high temperature within vacuum heat collector. It lowers heat exchange efficiency. After two years, the heat exchanger efficiency is obviously lowered, and the supply water is unsteady.	With patent design,the set operates steadily rapidly exchange heat dynamically. Scale formation rate is low. Supply water for a long time is steady. Water supply is steadyfor long.
Scope of application	The floor space occupied is large(1㎡ absorbing board produces water about 60L/water day) Restriced by site. Absorbing effectefficiency impacts a lot by temperature.	The floor space occupied is small. Quickly adapt to all kinds of site setup demand: below-10℃-40℃ environment, it can operate efficiently.
Flexibility	Single regular mode design	According to users practical need, it designs flexibly, managing the system openly, regulating operation ratio freely.
