A heat pump is part of a heating and cooling system and is installed outside your home. Like an air conditioner, it can cool your home, but it’s also capable of providing heat.

An air-source heat pump works by transferring heat from the outside air to an indoor space. A fan draws in air from outside and transfers it to an evaporator, which is situated in the heat pump. A refrigerant circulates inside the pump, which changes its physical state and evaporates even at low temperatures. The refrigerant steam needs to be raised to a level where it can be used for your heating and hot water, so it’s compressed using a compressor. The heat produced in this process is transferred to the heating and hot water systems in your home.

In cooling mode, a heat pump absorbs heat inside your home and releases it outdoors. In heating mode, the heat pump absorbs heat from the ground or outside air (even cold air) and releases it indoors.

How does the heat pump water heater achieve the effect of saving energy?

When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.

What should we pay attention to when using heat pump water heater?

temperature, water consumption

Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.

How much hot water can be made

In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.

What are the operational advantages of heat pump water heaters?

The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.

The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.

Guangdong JNOD New Energy Technology Co., LTD. has focused on the field of heat pump water heaters for many years, it commits to providing perfect service for every customer in the world.

Under normal circumstances, when the average temperature is -5°C, the Heating and Cooling Heat Pump can generate more than three times the amount of heat per kWh of electricity consumed, and the energy saving efficiency is as high as 75% compared to the direct conversion of electrical energy into heat; when the average temperature is - At 15°C, 1 kWh of electricity consumption can generate more than twice the heat; even at -25°C, the Heating and Cooling Heat Pump can normally provide heat for the room.

What are the similarities and differences between Heating and Cooling Heat Pump and solar water heaters?

From the scope of application, heating continuity, operating cost, and installation conditions, Heating and Cooling Heat Pumpis easier to popularize than solar heating equipment, and solar heating equipment will be more affected by environmental factors. At the same time, the thermal efficiency of Heating and Cooling Heat Pump is very high, consuming 1 kWh of electricity can get three heat energy, and even if the thermal efficiency of solar energy reaches 100%, consuming 1 kWh of electricity can only generate 1 heat energy. It can be seen that the public is most concerned about energy saving. When the environment is harsh in winter, the energy consumption of Heating and Cooling Heat Pump is lower than that of solar heating equipment.

What is PTC heating with Heating and Cooling Heat Pump?

PTC electric heater is a kind of heater with automatic temperature control and power saving. It uses PTC heat-sensitive ceramic element as heating source, corrugated sheet made of aluminum alloy as radiator, and the heater is composed of bonding and welding. . Electric vehicle air-conditioning heater PTC generally collects data from temperature sensors through the air-conditioning controller, and adjusts the output power to achieve temperature setting. Currently widely used in pure electric vehicles. However, when the Heating and Cooling Heat Pump is used for heating in winter, the power consumption of the battery is very large, which seriously affects the cruising range. Now they have turned their attention to the heat pump solution, or the parallel solution of the two.

What are the advantages of using the Heating and Cooling Heat Pump?

First, energy saving is beneficial to the comprehensive utilization of energy. Heating and Cooling Heat Pump absorbs the low temperature heat energy in the air, and converts it into high temperature heat energy after being compressed by the compressor, and its energy saving effect is quite significant;

How does the Heat Pump Hot Water Heater provide hot water?

The basic principle of heat pump water heater: It mainly consists of compressor, heat exchanger, axial fan, heat storage water tank, water pump, liquid storage, filter, electronic expansion valve and electronic automatic control. After switching on the power supply, the axial fan starts running, the outside air flows through the evaporator for heat exchange, and the reduced temperature air is expelled from the system by the fan. A kind of low pressure working medium gas is compressed into high temperature and high pressure gas and fed to the capacitor. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and fed to the consumer for use. The working medium is cooled to a liquid and the liquid expands. After the valve is throttled and cooled, it flows back into the evaporator. This cycle works repeatedly, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the water tank for heat preservation gradually rises and finally reaches about 55°C, which is just suitable for people to take a bath.

What is the current market situation for Heat Pump Hot Water Heaters?

Heat pump water heaters are a new thing on the market, and consumer awareness of this is still very low. There are many people who think that it is impossible to get three parts heat with one part heat, and the same applies to other products related to the application of heat recovery technology, although the popularity of heat pump air conditioners was very high.

People's understanding is limited only to the fact that air conditioning is a large electricity consumer, but they do not know that it is more energy-saving than the coal-fired ball furnace. As some larger shopping malls have not yet sold air-powered water heaters, consumer awareness of air-powered water heaters is still very low.

In order to meet these growing requirements, Guangdong JNOD New Energy Technology Co., LTD. has various heat pump water heaters, which allow to increase the products and make them more effective, reliable and consistent.

Air source heat pumps are a relatively new technology that can be used to heat your property in a more environmentally friendly and energy efficient way. As they use the ambient air outside of the property as their heat source, there is no need for a gas supply. This makes them a suitable heating solution for most homes, regardless of whether they are connected to the gas network.

How does an air source heat pump work?

There are 2 types of air source heat pump: air to water and air to air. This is how each of them works.

How an air to water heat pump works

Here is a step by step breakdown of how an air to water heat pump works:

1.    The heat pump has an outdoor unit, which contains a fan that draws air in from outside the property. This air then passes over tubes or coils filled with liquid refrigerant.

2.    The liquid refrigerant is much colder than the ambient temperature, even if the outside air is at sub-zero temperatures, and begins to heat up when air is passed over it.

3.    As the refrigerant continues to heat up, it becomes steam which is moved to a compressor. This compresses the steam which raises the temperature of the refrigerant even further.

4.    The heat of the refrigerant is then transferred to the water in the central heating system in your home, and any water stored in a hot water tank, for hot running water.

5.    The refrigerant, which has now passed on its heat, is then cooled and cycled back to begin the process again.

How an air to water heat pump works

Air to air heat pumps are essentially updated versions of air conditioning units that don't only cool air, but can also heat it. They work in the same way as an air to water heat pump, but transfer heat to the air in a ventilation system, rather than to the water in a central heating system.
A big drawback of air to air heat pumps is that they require a property to have air ducts installed throughout, in which to distribute warm air. They are also incapable of heating running water. This means they are not generally suitable for existing and older properties.

We have provided an in depth comparison of these heat pumps in our Air to Water Heat Pumps vs Air to Air Heat Pumps article.

Different types of air source heat pump

Not only are there air to water and air to air heat pumps, but each of these types of air source heat pump is generally available in different models. Namely monobloc air source heat pumps and split air source heat pumps.

Monobloc heat pumps

These are a large single outdoor fan unit which connects directly to the central heating system and will need to be located close to your property. There is no indoor unit, which can help to free-up space inside your property.

Split heat pumps

Split heat pumps consist of 2 main units: the outdoor fan unit and the indoor heating and cooling unit. These generally take up less space outside, but will require the use of some inside space.

To understand the pros and cons of monobloc and split air source heat pumps, and to find out more about how they differ, you can go to our article: Split Heat Pumps vs Monobloc Heat Pumps

Air source heat pump temperatures

Air to water heat pumps often come in 2 separate temperature ranges: low temperature and high temperature. It's important to know what each of these temperature types are as they could affect your installation costs.

Low temperature heat pumps

While traditional gas boilers will heat the water in a central heating system to temperatures of around 80°C to ensure the radiators around the property are providing ample heat. Low temperature air source heat pumps are only capable of heating radiators to a temperature of around 60°C. Due to the lower maximum temperature these heat pumps are capable of producing, more heated surface area is required to keep a property warm. This means you will need bigger radiators or underfloor heating to truly benefit from the installation of a low temperature heat pump.

High temperature heat pumps

Generally, high temperature air source heat pumps are capable of heating the water in a central heating system to around 75°C – 80°C. This is more in line with the temperatures provided by gas boilers. This makes them easier to integrate into an existing traditional heating system, but they do require more power to run.

The benefits & disadvantages of an air source heat pump

There are many benefits to getting an air source heat pump installed at your property, but there are some disadvantages too. To help you make the right decision for your home, we created the article: Air Source Heat Pumps vs Gas Boilers. This covers the advantages and disadvantages of each technology, cost comparisons and things you will need to consider when getting either heating solution installed.

Finding an Installer

As air source heat pumps are a relatively new technology, you may find it harder to find a heating engineer in your area that's well versed with installing them. More and more heating engineers are starting to adopt air source heat pumps as a heating solution they will install, but it may not be clear where to find them.
Fortunately, this is something we can help with. Simply click the link below and we'll find you up to 3 quotes from air source trained heating engineers in your area.

As heat pumps are more and more popular in the market, people want to know if it's worthy to use it.

Of course Yes! Heat pump water heaters are worth the cost.

More Efficient

Heat pumps are significantly more energy efficient than normal electric or gas hot water heaters because instead of using energy to generate new heat, they collect existing ambient warmth and transfer it to the water. This efficiency can save you hundreds of dollars on energy bills each year.

Tax Incentives and Rebates

With tax incentives and state-sponsored sales rebates, energy efficient heat pump water heaters can actually be a more affordable choice than most homeowners would expect. Though the upfront cost is high, most homeowners pay back heat pump water heaters within the first or second year alone. And heat pump water heaters are long-lasting –  a good, well-maintained heater can last between ten to fifteen years.

Environmentally Friendly

Because heat pumps are more energy efficient than conventional hot water heaters, they do not use as much electricity and/or natural gas, which reduces greenhouse gas emissions. In fact, it estimates that if all residential water heaters were replaced with heat pump water heaters, there would be up to 140 billion pounds of greenhouse gas emissions are saved annually.

A heat pump is part of a heating and cooling system. Like an air conditioner, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.

HOW A HEAT PUMP WORKS

A.COOLING MODE

One of the most important things to understand about heat pump operation and the process of transferring heat is that heat energy naturally wants to move to areas with lower temperatures and less pressure. Heat pumps rely on this physical property, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. This is how a heat pump works.

B.HEATING MODE

A Heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed by the aptly named reversing valve. The flow reversal means that the heating source becomes the outside air (even when outdoor temperatures are low) and the heat energy is released inside the home. The outside coil now has the function of an evaporator, and the indoor coil now has the role of the condenser.

The physics of the process are the same. Heat energy is absorbed in the outdoor unit by cool liquid refrigerant, turning it into cold gas. Pressure is then applied to the cold gas, turning it to hot gas. The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle.

Now, more and more families are making the preparation for the Winter, Like installing the heat pump for house heating and hot water.
