What is a direct heat pump water heater?
What are the characteristics of direct heat pump water heaters?
What is the main structure of the direct heat pump water heater?
The direct heat pump water heater is also known as the fast or fast heat pump water heater. The basic characteristics of the direct heat pump water heater are: cold water and superheated water, as long as the tap is turned on, the energy source will continuously supply hot water within a few seconds. Turn off the faucet when you don't need hot water.
According to different heating forms, direct heat pump electric water heaters can be divided into the following three types:
①, bare electric wire heating electric water heater;
②, electric film heating electric water heater;
③, electric heating tube heating electric water heater.
The heater of the direct heat pump water heateris set in a tank frame, which cannot withstand too high water pressure. At the same time, the left and right poles of the tank frame and the two poles introduced by the heating wire will be affected by water pressure for a long time. be damaged. Therefore, direct heating heat pump water heaters cannot be made into the post-system, but are all made into the front-system. In addition, in order to ensure the safe use of direct-heat heat pump water heaters and no dry burning occurs, a pressure sensing activation switch with water flow as a signal is installed at the cold water inlet, and the pressure sensing activation switch diaphragm can withstand the pressure. It is limited and cannot withstand pressure for a long time, so direct heat pump water heaters are generally made into the former system.
A typical direct heat pump water heater is mainly composed of a heating tank plate, a pressure sensor, a power regulator, a water volume adjustment faucet, a water inlet pipe and a water outlet pipe component, among which the heating tank plate is the key component of the direct heat pump water heater. It consists of a groove weight, a sealing ring, a cover and an electric heating element, and the electric heating element is located in the groove of the groove plate.
The direct heat pump water heater works by direct conduction heating. Since the electric heating element is placed in the groove of the groove plate, when the cold water flows through the groove, it can directly flow through the surface of the heating element to be heated. And because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and hot water with a higher temperature can be obtained at the water outlet.

In the Heating and Cooling Heat Pump structure, the refrigerant directly exchanges heat with the air to be treated, without secondary heat exchange in the middle, which reduces the intermediate heat exchange links, which can effectively reduce the energy consumption of the system and improve the heat exchange efficiency.
What is the technological advancement of Heating and Cooling Heat Pump compared to traditional air conditioners?
Where can Heating and Cooling Heat Pump be used?
Why does Heating and Cooling Heat Pump become the choice of more and more consumers?
The refrigeration principle of the traditional air conditioner is to use the change of the physical state of the refrigerant. The change from the gaseous state to the liquid state will emit heat, and the change from the liquid state to the gaseous state will absorb heat. The "reverse Carnot" cycle used for Heating and Cooling Heat Pump is opposite to the refrigeration principle of traditional air conditioners. Using a "four-way electromagnetic reversing valve", a refrigeration cycle or a heating cycle can be realized, so that the car can get cold or hot air. . In the cycle of air-conditioning refrigerant, a large amount of heat will be released during the process of liquefying high-temperature and high-pressure gas into high-pressure liquid in the condenser, which is the principle of heat pump heat release. In winter, the reversing valve can be used to change the flow direction of the air-conditioning refrigerant. At this time, the evaporator acts as a condenser to release heat in the reverse cycle, forming a "heat source". At this time, only a small amount of electricity is consumed, and a large amount of heat from the outside can be transported and "pumped" into the pure electric vehicle to become a heat pump. However, the heating effect of heat pumps in low temperature environments needs to be improved.
The heating principle of Heating and Cooling Heat Pump is completely different from that of traditional solar water heaters. Air source heat pumps use air, water, solar energy, etc. as low-temperature heat sources. The hot water is directly sent to the user through the circulation system as hot water supply or small area heating using fan coil units. Heating and Cooling Heat Pump is the best solution for large, medium and small hot water centralized supply systems in school dormitories, hotels, bathing centers and other places.
Heating and Cooling Heat Pump is one of the most advanced energy utilization products in the world today. With the rapid development of the economy and the improvement of people's living standards, hot water for domestic use has become a necessity for people's lives. However, traditional water heaters (electric water heaters, fuel-fired water heaters, and gas water heaters) have disadvantages such as high energy consumption, high cost, and serious pollution; The operation of energy-saving and environmentally friendly solar water heaters is restricted by meteorological conditions.

②Temperature protection: Excessive exhaust temperature protection, compressor overcut protection, hot water temperature protection
③ Power protection: lack/reverse phase protection, compressor overload protection.
① The anti-condensation sensor of Swimming Pool Heat Pump can avoid condensation and condensation on the inner surface of indoor glass windows and walls. When the temperature at the indoor anti-condensation dew point is too low, the anti-condensation sensor installed in the place will fed back the information to the unit control system so that the unit can re-adjust the indoor relative humidity, so that the temperature here is higher than the dew point temperature to prevent condensation.
② If there are parts that are particularly prone to condensation and condensation in the swimming pool space, the Swimming Pool Heat Pump can be equipped with a special anti-condensation and condensation system to ensure that the temperature of the condensation-prone parts of the swimming pool is above the dew point temperature.

Compared with ordinary central air conditioning refrigeration and gas wall-hung boiler heating, what are the advantages of Heating and Cooling Heat Pump?
What are the advantages of using the Heating and Cooling Heat Pump?
What is the working principle of Heating and Cooling Heat Pump?
The common heating and cooling equipment on the market is mainly fluorine system heating and cooling air conditioning or the combination of gas wall-hung boiler heating and central air conditioning refrigeration.
The main advantage of Heating and Cooling Heat Pump compared to ordinary heating and cooling air conditioners is high comfort. The fluorine system heating and cooling air conditioner directly controls the indoor temperature through the flow of the refrigerant, and the refrigerant directly exchanges heat with the air. This heat exchange method has two disadvantages: First, the temperature of the air outlet of the air conditioner is very low or very high (7°C-12°C during cooling, 40°C-50°C during heating), the body feels very bad, and it is bitingly cold in summer. The winter is hot and dry; second, although the fluorine system air conditioner has a relatively fast cooling and heating speed, it will also cause a large amount of moisture in the air to be taken away due to the rapid heating and cooling speed, resulting in excessive indoor dehumidification and drying.
1) The unit of Heating and Cooling Heat Pump has high energy efficiency ratio, energy saving and electricity saving.
2) The water temperature of the Heating and Cooling Heat Pump is generally constant at 12-22°C, which is 7°C for the water supply in summer, 12°C for the return water, 45°C for the water supply in winter, and 40°C for the return water, and the temperature difference between them is small. , so the unit has less work and more energy.
During the operation of Heating and Cooling Heat Pump, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer working medium. After the working medium vapor is compressed by the compressor, the pressure and temperature rise. When the high-temperature vapor passes through the special annular pipe bonded on the outer surface of the water storage tank, the condenser condenses into liquid and transfers the heat to the water in the water storage tank of air source heat pump.

There are 2 different ways an air source heat pump can provide heat in your home: by heating the air in the rooms or by heating the water in the central heating system, but which option is best for your home? We've compared these different heat pumps, to help you find out.
As the name suggests, air-to-water heat pumps use the ambient air outside of a property to heat the water in the central heating system. They are the more frequently seen air source heat pumps on the market, and come with several benefits and disadvantages.
Benefits of an air-to-water heat pump
Air-to-water heat pumps come with several benefits when compared to air-to-air heat pumps.
Compatible with traditional central heating systems
According to the English Housing Survey 2019-2020, 90% of households in the UK have central heating with radiators as their main heat source. That means, unless you're among the select few, you are going to want an air source heat pump that's compatible with your existing central heating system. Air-to-water heat pumps are designed with this very purpose in mind. Air-to-air heat pumps are not compatible.
Easier to install
As the air-to-water heat pumps will generally connect directly to the central heating system they are usually a lot easier to install than air-to-air heat pumps. Installing an air-to-water heat pump in a property with existing central heating is similar to replacing a boiler, whereas installing an air-to-air heat pump would require the installation of air ducts throughout the property.
Not just for heating
Although air source heat pumps are mainly considered for heating properties, that isn't the only thing they do. Air-to-water heat pumps will heat the water in your property for your central heating, but can also be combined with a hot water storage tank to provide hot running water too.
Disadvantages of an air-to-water heat pump
Air-to-water heat pumps don't just come with benefits, there are some disadvantages too.
Air-to-water heat pumps are not cheap. Depending on the size of the unit you need and which manufacturer you pick, you could end up paying more than £10,000 for an air-to-water heat pump, excluding the cost of installation.
In comparison, you can get some air-to-air heat pumps for less than £1,000. Even if the cost of installation is high, you could still spend less on getting an air-to-air heat pump installed than you would on just buying the parts for an air-to-water heat pump.
Requires more space
In addition to the space a hot water storage tank would take up to allow for hot running water, due to radiators being required, air-to-water heat pumps still take up more room in the property than air-to-air heat pumps do. This isn't much of a problem if you already have radiators installed, but to maximize space in a new property air to air heat pumps are the better option.
In what sounds like a much simpler process, air-to-air heat pumps extract heat from the ambient air outside of a property and transfer it to the air inside of a property. If you'd like more detail on how air source heat pumps work, have a look at the following article: What is an air source heat pump?
Benefits of an air-to-air heat pump
There are several benefits to having an air-to-air heat pump rather than an air-to-water heat pump.
Heat and cool
As the air to air heat pumps is essentially air conditioning units that are capable of heating a property, they can also be used to cool a property when the weather is hot. Many manufacturers refer to them as climate control solutions because they aren't just for heating a property, they can cool it too.
Air-to-air heat pumps may require the installation of air ducts throughout the property, but once they have been installed, each room will feel more spacious. This is because there is no need for radiators which take up wall room and floor space. For newer, less spacious properties, air-to-air heat pumps could help you make the most of your space.
As mentioned earlier, air-to-air heat pump units are considerably cheaper than their air-to-water counterparts. Some air-to-water units can be 10 times more expensive than an air-to-air unit, which is something to think about.
Disadvantages of an air-to-air heat pump
Air-to-air heat pumps don't just come with benefits when compared to air-to-water heat pumps, there are some disadvantages too.
Not compatible with traditional central heating systems
If you have an existing central heating system and want to replace a gas boiler with an air-source heat pump, air-to-air heat pumps are not for you. As they only heat the air in a property, they cannot be connected to the central heating system and are completely incompatible.
Higher installation costs
Although like-for-like installation costs for both types of heat pump are generally quite similar, unless you have a property with existing air conditioning ducting, the cost of installing an air-to-air heat pump is likely to be higher as there will be more work to do.
No hot water
Air-to-air heat pumps do not heat the water in a property. This means you will need a secondary source of heat to provide hot running water throughout your home. While this is possible through solar power and other water heating solutions, it is still a separate cost that is avoided when installing an air-to-water heat pump.
Having learned the advantages and disadvantages of these air source heat pumps, you should now be able to make a decision on which would be best suited to your circumstances. However, as there is a lot to consider when getting an air source heat pump installed, we would recommend seeking the advice of a local heating engineer. They can ensure you get the right solution for your home's unique circumstances. Fortunately, we can help you find qualified engineers in your area, who will provide you with free, no-obligation quotes.
