Electric Wall Hung Boiler is called Electric heating boiler, working diagram is To circulate Whole system water flow through circulation pump , Then to get hot water by our heating element . Our Electric boiler can work with radiator , underfloor system ,heat pump Or solar energy system .(heating power range from 3KW to 50KW)

 Boiler Series :  Single heating boiler  /  DHW and Heating combi Electric boiler

 Boiler Kinds :   Closed type internal pump Boiler

                                   ( Boiler inside with Grundfos Pump and expansion Tank)

                                   

                                    Opened type external pump  Boiler

                                     (Buyer should supply opened fill water tank and pump )

The MOdel  KFN30 is   DHW and Heating combi Electric boiler  .

Boiler  heating  power :12-24KW      Hot water side Power is 10-16KW

Safety and Heating boiler on the instrument:

1- Digital Remote Control: (Turn on/off, stall.temperture and time adjustment )

2- Tank expansion (Adjust system pressure)

3- Heating Unit: ( for hot water )

4-Safety Relief Valve: ( Active at 3 bar gauge)

5-Pressure Switch: ( Prevents dry running of the instrument )

6- Barometer: ( Pressure gauge ) observe the water pressure of the tank expansion

7- Pump :a kind equipment which help the fluid to work normally in the system .

8.-Filter: the impurities of the water will isolate through the filter .

9.Safty Valve:it’s a protect equipment .

 

 

Features

 

Timmer function : Timmer functions meet different customer need . for saving compustion

 

Wide temp setting function: the water temp setting in range of 30-85degrees.

 

Over temp protection: When the heating element temp exceeds 95degrees.over-temp protector starts and boiler stop working .

 

Dry heating protection: when the heating element temp exceeds 110degrees, dry-heating protector start, disconnect the power supply ,then we should button “return”key by manual .

 

Leakage protection: when the system has leakage phenomenon.leakage protect function start and boiler stop working . Display screen display E2 .

 

Pressure gauge : Show system currently pressure (normal pressure will be 1-1.5bar)

 

Antifreeze function: when the system temp is below 3degrees,the system automatically start to heating .when temp heated 10degrees ,it will stop heating .

 

Filter: Filtering the impurities of heating system to protect water flow switch and pump which not be stuffed .we should clean up filter in time .

 

Safety valve : When system pressure exceed 3Bar, the by pass relief valve automatic pressure –relief to ensure system safety.

 

Error Code display: Error code display on screen, easy for find problem and maintenance.

 

Circulation Pump : We used import Grundfos circulation pump .

 

expansion tank (lower than 8KW,it’s 2.5L ; higher than 8kw, it’s 5L)

 

(if customer need install room thermostat , We will supply room thermostat wire for it )

 

 

Manufactory Suggest :

 

Boiler with Underfloor system : Suggest to set 50degrees

 

Boiler with radaitors : suggest to set 70-75degrees

 

While we choose heating power, the fellowing conidtions have to be taken into consideration:

 

*While calculating demand for thermal energy, a number of factors should be  taken into consideration:- building cubature- level of room ventilation- heat accumulation

 

-value of heat transfer through walls, windows and ceilings
