Specifications

Safely and reliable, high energy efficiency ratio, energy-saving, widely used.

                                                   Air to Water Heat Pump 

 

1. Based on inverse cannot cycle principle, the unit can transfer energy in air into water through heat pump system, raise the water temperature to meet service conditions by consuming part of electric power.

2. It has high energy efficiency ratio, can produce 4kw heat by consuming every 1kw electric power. Comparing with traditional electric water heater which produces 0.95kw heat by consuming every 1kw electric power, its economic benefit is more than 4 times bigger than traditional heaters, or more than 2 times bigger than coal/oil (natural gas) furnace. Comparing with solar water heater, it is not restricted by installation conditions or weather conditions, can be used in all seasons.

3. Safely and reliable, electricity will not contact water directly during heating process, users will not suffer electric shock risk, nor explosion risk or poisoning risk of oil/gas furnace.

4. Environmental friendly, it will consume only part of electric power during operation, will not bring any pollution to the environment.

Application range:

It is mainly applied to houses, hotels, restaurants, schools, hospitals, swimming pools, bathhouses, large high grade office buildings which have requirements on hot water.
