Electric heating furnace is also called electric heating boiler. Electric heating boiler belongs to a kind of boiler products. It is an engineering process that converts electricity into energy to heat the water in the boiler and produce steam or hot water. It is one of the mainstream combustion modes in boilers at present. It has many advantages, such as intelligent operation, high thermal efficiency, safety and reliability. The main heating of electric heating furnace is water heating, which is heated by heat source (that is, boiler). The main heating methods are household heating and central heating.

分戶供暖所指的是用戶自行采購安裝小型供熱設備進行供暖。分戶供暖可隨時開啟，提供了采暖時間上的自由。分戶供暖可實現每家每戶溫度可隨意調，已適應不同體質人群的需要。另外每個家庭還可根據自己的實際情況，在裝修過程中隨意增加或減少暖氣片片配置。而集中供暖是不允許這樣操作的。

Household heating means that users purchase and install small heating equipment for heating. Household heating can be turned on at any time, providing freedom in heating time. Household heating can realize that the temperature of each household can be adjusted at will, which has adapted to the needs of people with different physique. In addition, each family can also increase or reduce the radiator configuration at will in the decoration process according to their own actual situation. Central heating is not allowed to operate like this.

集中供暖，指集中集團式供暖的一種形式。一般都是按一個采暖季度，每平方麵積收費的。

Central heating refers to a form of central group heating. Generally, it is charged per square area according to a heating quarter.

電采暖加熱電熱元件的形式分別有電阻式、電極式和電膜式。

The forms of electric heating elements include resistance type, electrode type and electric film type.

1、電阻式是采用高阻抗管形電熱元件，接通電源後，管型電熱元件產生高熱使水成為熱水或蒸汽。管型電熱元件由金屬外殼，電熱絲和氧化續三者組成。該種元件的優點是水中不帶的電，使用較為安 全，對水質也不造成汙染。但由於鍋爐容量的增加需要，依靠管型電熱元件的數量來實現，這種鍋爐的容量收到電熱元件結構布置的限製；；問題是鍋爐容量的增加依靠管型電熱元件的數量來實現，並按投運數量來調節鍋爐負荷。因此，這種鍋爐的容量收到電熱元件結構布置的限製。

1. Resistance type adopts high impedance tubular electric heating element. After the power is connected, the tubular electric heating element generates high heat to turn water into hot water or steam. The tubular electric heating element is composed of a metal shell, an electric heating wire and an oxidation continuation. The utility model has the advantages of no electricity in the water, safe use and no pollution to the water quality. However, due to the increase of boiler capacity, it depends on the number of tubular electric heating elements, and the capacity of this boiler is limited by the structural arrangement of electric heating elements;; The problem is that the increase of boiler capacity depends on the number of tubular electric heating elements, and the boiler load is adjusted according to the number of put into operation. Therefore, the capacity of this boiler is limited by the structural arrangement of electric heating elements.

2、電極式鍋爐的工作原理是把電極插入水中。利用水的高熱阻性，直接將電能轉換為熱能，在這一轉換過程中能量幾乎沒有損失。電極式鍋爐運行十分，一旦鍋爐斷水，電極間的通路被切斷，電功率為零，鍋爐自動停止運行，鍋爐不會發生幹燒現象。

2. The working principle of electrode boiler is to insert electrodes into water. Using the high thermal resistance of water, electric energy is directly converted into heat energy, and there is almost no loss of energy in this conversion process. The operation of the electrode boiler is very safe. Once the water supply of the boiler is cut off, the path between the electrodes is cut off, and the electric power is zero, the boiler will automatically stop running, and the boiler will not dry burn.
