      Just up the oil, the gas price has come along. From the Municipality, due to the impact of international crude oil rose sharply factors, Huizhou bottled gas yesterday jumped $ 5, users shouted, "can not afford." Widespread use of bottled gas, relates to every household to cook, shower. So, we have called in the air can do to replace the new energy-saving water heaters - air to water heater.

      According to the ambassador, Mr. Jiang Shaolei air express, air to water heater is the world's most energy-efficient water heater. It is transferred through the compressor acting transport heat from the air into the tank, the water is heated. The energy saving effect is four times the electric water heater, gas water heater three times, about 2 times the solar water heater. Further, since the separation of water from the air to the water heater principle, to prevent electrical shock and carbon monoxide poisoning and other accidents, and thus safer to use.
