Currently, the need to use hot water in every family, especially when winter comes, is an indispensable need. Equipment such as water heaters and solar water heaters are no longer strange to users. However, there is another type of hot water supply technology that many people probably do not know about, which is the installation of a central hot water pump cluster. Therefore, invite you and P69 JSC to learn and answer questions about this technology through the following article!

What is the central hot water pump cluster system?

Central hot water system, also known as hot water system using heat pump technology, is a system consisting of a set of water heating devices controlled by sensor relays. Operating based on a system of equipment such as heat pump, circulation pump, temperature sensor, electric valve to control water flow, safety valve…

The central hot water system has a distinct heating technology that is superior to conventional hot water supply methods. Water is heated quickly in just a few minutes, with large capacity to meet abundant hot water use without the need for a water tank.

Central hot water system is a system of exchanging environmental air through heat exchanger, cooling the wind through the compressor, bringing the incoming refrigerant to be heated to the heat exchanger to heat the water and vice versa, thermal sensor relay degree. Operated by safety control valve and circuit breaker.

Installation application of central hot water pump cluster

Today’s central hot water system, widely used in life, can be divided into 3 areas of use as follows:

• Central hot water system for households
• Central hot water system for industrial use
• Central hot water system for swimming pools, spas, resorts.

Benefits of installing a central hot water pump cluster

The central hot water pump cluster system is a modern water heater system, bringing many benefits to users, so it is chosen by many people:

• The durability of the system is high, without worrying about burning the tank like a traditional water heater.
• Low system operating costs, helping to save costs
• For high efficiency to save electricity 70% – 80%
• Free heat source, environmentally friendly
• High efficiency and energy saving: using this type of water heater also reduces energy waste. To heat the steam, you can use equipment such as heaters, air conditioners, heaters, fan heaters, etc. In the summer, the system will create cool air to replace the air conditioner and can customize the temperature to suit the family. family, convenient for winter.
• Easy to install as well as disassemble the simple systems, so when the house design changes, there is no fear of buying a new or damaged system.

Detailed installation instructions for central hot water pump assembly

Step 1: Survey the needs of use and field materials

Step 2: Estimate materials on the basis of optimization

Step 3: Transport equipment for installation and test run

Step 4: Acceptance – maintenance – warranty

Notes when installing Central hot water pump cluster

4 important notes when installing the central hot water pump assembly include the following steps:

1. Choose a suitable installation location

The installation location of the central hot water system must be suitable, such as cool, fresh, good ventilation, making use of waste heat as possible.

The location should also be close to the water source to shorten the pipe length. Besides, it is advisable to avoid using alum, saline water when producing hot water, if there is a customer, a water treatment tank can be installed.

2. Design insulation layer for central water heater system

Hot water when transported on pipes will have heat loss to the outside, especially in winter because the temperature difference is larger, so the possibility of heat loss in the pipeline is greater. Central hot water system heat pump will have to work more to meet the demand, so it will consume more electricity. Therefore, it is necessary to install an additional layer of insulation for the pipes, this layer not only protects the pipeline but also limits heat loss to the outside environment, saving energy for the whole system. system

3. Arrangement of circulation pump and return water line

The water after heating is not always used immediately, but instead there will be periods of time when the water is not used. Thus, the hot water on the pipe will cool down due to heat loss, which will cause waste of energy and time.

Installing a circulation pump, return water line and a temperature sensor arrangement will make it easier for the hot water system to recover the cooled water on the pipe and reheat it. This will help maintain the water temperature in the line. pipe is always maintained stable.

4. Install an extra hard water filter

Hard water clogs pipes, quickly punctures the insulation tank and reduces the efficiency of the heat pump. So if the water source contains a lot of Ca2+ ions, or Mg2+ ions (hard water), customers need to install a softening system. water first.

Currently, the water softener commonly used by the central heat pump hot water system is a Platinum bar placed in an insulation tank.

Which space is the central hot water pump cluster suitable for?

With an uncomplicated design and operating principle, the central hot water system is suitable for many different spaces:

1. For small and medium spaces:

• Small and medium-sized spaces such as hotels, small-scale motels, villas, medium-sized schools, etc. can install a central hot water system at one location with the principle of cyclic operation. generate hot water flow by heat exchange using compressor.
• With this system, the system uses optimal energy to limit waste and can be used at any time, can customize the temperature to suit the family, convenient for winter use. With a small scale, the central hot water system also has the ability to cool water like an air conditioner in the summer for convenient living.

2. For large spaces:

The central heat pump hot water system is also very suitable for large-scale spaces such as schools, hospitals, resorts, large-scale hotels, swimming pools, etc. Installation of this system will include classes. item:

• Forced heating module: This module uses heat pump, boiler, resistance heating rod to generate heat source and generate hot water for users.
  Indirect heat exchanger module: This module includes heat exchanger plates, heat exchanger tubes, etc. to increase heat processing efficiency without generating scale, ensuring water hygiene.
• Indirect heat exchanger module: this module has the function of storing water after heating, this helps to ensure the amount of water for the user.
• Auxiliary energy sources: These are energy sources such as solar energy or water recovered after the heating process. Install this item to reduce operating costs and protect the environment.
• Automatic hot water circulation: This is an item designed with the function of regulating the temperature of the water to help the water distributed after heating have an even temperature.
