What are the advantages of central water heaters? Disadvantage analysis

1. Introduction to the central hot water system

The central hot water system actually means that hot water comes when you turn on the faucet, and hot water comes out of the shower. Provide convenience for life. At present, it is generally only used in hotels, bathing places, clubs and other places. With the improvement of living standards, families and some small and medium-sized hotels are also gradually adopting it. Hot water at any time allows you to live a comfortable life.

II. Composition of the central hot water system

The main components of the central hot water system

1. Heat source

There are many types of heat sources You can choose from coal stoves, electric water heaters, gas stoves, oil boilers, solar hot water, air source heat pumps, etc. At present, electric water heaters, air source heat pumps or solar energy are mostly used according to actual usage. Based on actual cases and application effects, Zhonghe Electric Water Heating recommends the use of solar electric water heaters, which have stable performance, no worries about seasonal changes, save energy and reduce costs.

2. Heat exchange

Due to the corrosive nature of water and the scaling caused by heating, it is usually in order to extend the service life of the heat source and ensure water quality. Use a plate heat exchanger or heat exchange fins between the heat source and the hot water storage tank.

3. Thermal storage

In order to ensure that hot water is available 24 hours a day, central hot water generally stores water in thermal storage tanks. The size of the water tank can be determined according to the usage. Generally, hotel baths are calculated based on 50L/person. Household use can be calculated individually based on actual population and usage.

The hot water storage tank has the characteristics of being able to store energy, with stable water temperature and guaranteed water quantity. In particular, users of peak and valley electricity price meters can store heat during low-price periods.

4. Circulation system

The circulation system is the heart of the entire central hot water system. Only circulating water can ensure that hot water comes out when the faucet is opened. A good water pump is the core to ensure that you can use it at any time.

Analysis of the advantages and disadvantages of volumetric central water heaters

Volume-type central water heaters need to frequently heat the water in the container to maintain a certain water temperature so that it can be supplied to users.

Advantages:

The instantaneous flow rate is very large, but it cannot continuously supply hot water.

If electricity is used as energy, it is not restricted by the type of gas and can be directly installed and used anytime and anywhere.

No waste gas is produced, keeping the surrounding environment hygienic.

Disadvantages:

The water storage container is huge and takes up valuable indoor space.

Since it is necessary to ensure the water temperature in the container, as long as the temperature drops, the main burner of the water heater will automatically work for heating. This wastes energy, increases the cost of use, and is not environmentally friendly.

No continuous water supply. Since its recovery time takes 1 hour or more (depending on the size of the container and the heating power of the water heater), when the hot water in the container is used up, the people behind it will have to wait for 1 hour or more. time.

It cannot maintain a constant temperature. During use, because the body is constantly replenished with cold water, the temperature of the outlet water will become lower and lower, and the phenomenon of hot and cold will occur.

Water storage containers are prone to scale. If the water heater is not used for a long time, the stored water will breed bacteria, which are harmful to the human body.
