Understand JNOD Electric Boiler System: An In-Depth Look at Their Types, Models, and Characteristics
Open Vented Type
The open-vented electric boiler requires the connection of a separate circulation pump, expansion tank and water tank. It is usually used in homes with space for an external water tank. This type of boiler is ideal for homes with multiple bathrooms that can also be heated.
Below are the sizes and voltages corresponding to the different models.
BQ: 5.5/7.5/9.5/11/13/14.4kW@230v/400v, 16/20kW@400V
BC: 5.5/7.5/9.5/11/13/14.4kW@230v/400v, 16/20/23/26kW@400V
BK: 40/52kW@400V
BE: 7/10/12/14/18/21/25/27kW@240V
It will have a smaller exterior size than other electric boiler types, which is more space-saving. The BQ has the smallest exterior size, the BC has 23/26kw size options, and the BK has the largest size.
Electric System Boiler
The system electric boiler has a built-in circulation pump and expansion vessel. Remarkably it has only one heating element. It is designed to be used in connection with a separate water tank, thus allowing it to provide central heating and a large hot water supply.
Below are the sizes and voltages corresponding to the different models.
BO/BF/BM/BW/BT/BE-S/BX:
5.5/7.5/9.5/11/13/14.4KW@230v/400v, 16/20/23/26KW@400V
Their difference:
BO/BF: same internal structure, different displays
BM/BW/BT/BE-S: same internal structure, different panels
BO/BF VS BW/BM/BT/BE-S: different expansion tanks, different displays
BX: glass exterior, touch display, different internal structure and display compared to above
Electric Combi Boiler
The electric combi boiler has a built-in circulation pump and expansion vessel like the system electric boiler. However, it has two heating elements and is more efficient. The two heating systems can run separately or at the same time. If you need a built-in water tank, there is also a model. Models that don’t need to be connected to a tank provide hot water on demand, instantly heated and flowing.
Below are the sizes and voltages corresponding to the different models.
BO-E/BF-E/BM-E/BW-E/BT-E/BP-E:
5.5/7.5/9.5/11/13/14.4KW@230v/400v, 16/20/23/26KW@400V
BE-E: 13/14.4KW@230v/400v, 16/20/23/26KW@400V
Electric combination boilers have almost the same exterior design as system electric boilers but have two heating elements inside, one on the side. BP-E is the model with a built-in 35L water tank.
Commercial Electric Boiler
Floor-standing electric heating boilers consist of several heating elements and are designed for large public places, such as schools, hotels, hospitals, and commercial premises.
Below are the sizes and voltages corresponding to the different models:
BG: 352/378KW@400V
BL: 158/220/315KW@400V
Understand JNOD Patented Heating Element: The Key to Efficiency
It is the first cast aluminum heating element technology to apply for a patent in China since 2009.
- With water and electricity separation technology, it won’t cause leakage.
- Water and corrosion resistance, no limescale for 5-8 years.
- It has a low surface heat load
- Heating efficiency is high with over 97% efficiency.
- The hot water is fully heated because it has at least 3 meters long stainless steel sink.
- It is a cast piece of the entire heating element, so it is also leak-proof.
- Cast aluminum heating element is the best choice for resisting hard water quality
- Over 8 years of life span

Applied to open-vented & system boiler types:
Connect to the external water tank to provide domestic hot water. This is achieved by connecting three accessories 1. DHW External Tank Plate (detects the tank temperature and transmits a signal to the main board) 2. Tank Temperature Probe: detects the tank temperature 3. 3-Way Valve: regulates the water flow direction.
Outdoor Temperature Probe: Sensing the outdoor temperature to adjust the indoor temperature by connecting the outdoor sensor.
How to choose the right size electric boiler for your house?
In terms of heating, 1KW=10m2. For example, if the user’s home is 90m2, we can recommend 9KW.
Specifically, it also depends on the regional climate, in hot summer and cold winter countries and regions, the heating heat load is 40-60W/m2, and 100m2 of the house needs a 6kW electric boiler. In colder areas, the heating heat load is 60-120W/m2, and a 100m2 house needs a 10kW electric boiler. In extremely cold areas, the heating load is 100-160W/m2, and a 100m2 house requires a 15kW electric boiler.
In terms of providing hot water, you need to consider the number of people living in the house, the amount of hot water and the time it is used. You can also consider the number of appliances that use hot water, such as washing machines, dishwashers and showers, and how long they are typically used.
