Classification of volumetric electric water heaters
Capacity type electric water heater according to installation way is divided into: wall hanging, horizontal, wall hanging, vertical and floor type three. When the water heater is installed, the level of the horizontal wall hanging on the wall, suitable for water heater in the capacity of not more than 100L, there are certain requirements of vertical wall strength wall; when the water heater is installed vertically hanging on the wall, suitable for water heater in the capacity of not more than 100L, there is a certain demand strength on the wall; floor type water heater can be installed vertically in the solid ground, suitable for water heater capacity of more than 100L.
The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe. This kind of water heater works under normal pressure, so it has lower requirements for making inner bladder and its structure is relatively simple. Today, most manufacturers of volumetric electric water heaters are closed electric water heaters
The volumetric electric water heater is divided into two types according to its export type: closed electric water heater and open type electric water heater. A closed electric water heater controls water quantity at one or more valves at the outlet and operates under tap water pressure
