JNOD BQ Series Open-Vented Electric Boiler
The BQ series oepn-vented electric boilers provides convenient and reliable space heating without the need for fossil fuels. They offer power outputs ranging from 5.5 kW to 14.4 kW with CE certification.
They can supply central heating and domestic hot water when connected to a domestic water tank and an expansion vessel. They can also serve as a backup heating source for heat pumps in extremely cold regions.
Open-vented electric boilers are designed for compatibility with external circulation pumps and water tanks, as they do not contain built-in components. This design results in a more compact unit.
