All of us know about air conditioners, which are composed of a compressor and other heat exchangers, and are filled with refrigerant. Powered air conditioners absorb heat from the air to lower the temperature; this is how the cooled air is generated. On the other hand, air conditioners also discharge heat outside. According to the principle of conservation of energy, the energy of discharged heat equals to the power injected to air conditioners; meanwhile, when adding the heat absorbed from the indoors, discharged heat will be two to six times of the power input.

Schematics Heat Pumps

(Heat pump water heaters share the same principles with air conditioners.)

Air conditioners:
Refrigerant is used while operating→ absorbing the air indoors, and separate cool air from the heat; this is how cooled air is generated, while the heat is discharged outdoors! Discharged heat, however, shall cause damages to the ozone layers and create greenhouse effects; similarly, it will destroy living qualities of mankind, since the damage to the Earth will grow stronger.

Heat Pump Water Heaters:
Absorbing the discharged heat from air conditioners→ compressed in the compressor before collected, and switch it to hot water via heat exchangers, so that to satisfy the demands of hot water during the entire day; this is how heat pump water heaters operate. In this case, heat pump water heaters make use of discharged and wasted heat, well as the heat in the air; meanwhile, they turn the heat to usable sources, reduce the damage of ozone layers and greenhouse effects; on the other hand, their pursue is to be eco-friendly, to protect the Earth, and to save power.

What are other functions of Heat Pump Water Heaters?

Heat Pump Water Heaters also contain functions of heating water, dehumidifying, cooling the temperature, as well as purifying the air.

• Heating Water: They contain functions of providing hot water continuously for 24 hours.
• Dehumidifying: They contain highly effective dehumidifying function of 20 to 30 liters (of water) within 24 hours.
• Cooling the Temperature: They produce 500kg of air in a 3-Ping close room, which helps to decrease the room temperature around 2°C to 3°C.
• Purifying: They purify indoor air; please clean the filtrating mesh every 3 to 4 months, depending on conditions of using.

What are the affects for heat pump water heaters to environmental protections?

• They do not require gas, and do not discharge exhausts; they do not require refrigerant that may destroy the ozone layer like traditional heat pump water heaters.
• Meanwhile, when the COP is above 2.6, they may save 2/3 of power costs comparing to electric water heaters, and may save 1/2 of power costs comparing to gas water heaters.
• This is because whenever 1 degree amount of power costs decrease s, 1.5 lbs. of CO2 reduces; the destruction of the ozone layer is thus reduced.

What are the advantages of heat pump water heaters?

• Safe: No combustion→ no exhaust discharged, so that to be dismissed from “gas explosion” and “gas poisoning”; they also contain safety devices to prevent from power leakage, and thus are secure.
• Comfortable: Provided with automatic constant temperature storage tanks, allowing the hot water to remain its warmth.
• Cost-saving: Saving 2/3 heating power costs (electric water heaters) or 1/2 gas fees (comparing with gas water heaters).

Where are possible locations to install heat pump water heaters?

• They are energy-saving water heaters that are rather suitable for indoors of apartment balconies, suites, households, and offices; additionally, their general power consumption of 220V/ 770W.
• One of the reasons why they are suitable for indoor space is that the air in the kitchen is usually hot and humid, especially when cooking; since heat pump water heaters contain dehumidifying capacity, they are very useful when installed in the kitchen.

How are the noises from heat pump water heaters?
They are equipped with acoustic treatment, so the noise ratio is even lower than household refrigerators or air conditioner split systems.

What is the working environment of heat pump water heaters?
It does not matter whether it is during daytime, at night, sunny or rainy; as long as the temperature is above 5°C, hot water of 60°C may be produced.
1200 liters of hot water may be produced within 24 hours.

When installing the heat pump water heater in the balcony, will other functions will fail?
When installing the heat pump water heater in an open balcony, other functions will fail; however, the heat pump water heater already contains functions of producing hot water with lower power consumption, costs, and is safer than gas water heaters, electric water heaters, and solar energy water heaters. Still, we would suggest our customers to confine the balcony with glass or acrylic materials, so that to allow convection of the air indoors. In that case, other functions may be performed, while segregating noises and dusts of outdoors. 80% the current users install their heat pump water heaters at the original place where they installed the gas water heater; however, since our products do not need gas to operate, there is not any danger of exhaust discharge and carbon monoxide poisoning.

What is the insulation effect of heat pump water heaters?
In the condition that heating is not constant, the temperature will drop 1 to 2°C during daytime; and same condition will result in temperature lowering around 3 to 5°C. Additionally, it may vary in accordance with room temperatures.

Do heat pump water heaters produce water scale?
Our heat pump water heaters provide indirect heating with medium temperature, which makes water scaling uneasy.
Oppositely, general electric water heater heat water at high temperature of 280-300°C, which allows water scaling.

What is the scope of use for heat pump water heaters?

• Preheating of hot water for factories and shower water for hospitals.
• Schools or private dormitories, and shower water for company faculty dorms.
• Large amount of heated hot water for hotels, and hot water provided for kitchens of hotels.
• Hot water for beauty salons, or preheating of drinking water in kindergarten or schools.
• Shower water for families, saunas, massage bathtubs, and SPAs.

Four Major Advantages of Heat Pumps

Differences between Air Conditioners and Heat Pumps

Power-driven heat pumps are suitable for heat pump water heaters; though the components in heat pump devices: the evaporator, heat pump, a condenser, and an expansion valve, the thermodynamic cycle process of the working fluid evaporating constantly (absorbing the heat in the environment) →compressing→ condensing→ throttling→ evaporating continues, so that to transfer large amount of decentralized thermal solar energy in the air, soils and water sources to domestic water usages.

Applicable for:
New community buildings, small suites or mansions, public institution dormitories, nursing care centers, hairdressing, medium or small hospitals, hotels, motels, and B&Bs, preheated water for industries.
