NRG Link


NRG Link is a very simple, yet highly effective system inter-linking solution from NRG Awareness, used to interconnect open solid fuel systems to sealed heating systems in a patented and uniquely safe way.

NRG Link provides for an unobstructed gravity heat leak circuitfrom a solid fuel appliance that incorporates an open expansion and cold feed. It is designed to transfer the heat from the solid fuel appliance into the sealed system. The unit is completely insulated with a built-in plate heat exchanger, pre-wired primary & secondary side pumps which are controlled by an integral thermostat. NRG Link is compliant with all solid fuel regulations with flow & return connections for the solid fuel appliance, a heat leak circuit and an efficient heat transfer medium to the sealed system.



NRG Link – The Easiest and Safest Way To Inter-Connect Sealed and Open Heating Systems

NRG Link is the only procurable Sealed to Open System Interlinking device that complies with all regulations and guidelines to interlink solid fuel open and sealed heating systems in a very safe and efficient way.

The NRG Link allows for a solid fuel central heating cooker or stove to be linked to a sealed heating system in retrofit or new-build situations. It includes for an open gravity circuit with standard safety facilities such as an open vent and cold feed facility that must be connected to a heat leak medium to comply with all manufacturer’s guidelines and regulatory conditions.

Interconnection type systems have always been an attractive idea to homeowners but likewise dual systems were always been troublesome for installers to get the ‘link-up’ right. For that reason, interlinking systems was generally seen as a specialist activity that should only be undertaken by qualified and experienced heating engineers as incorrect designs can be expensive to run and could well be very dangerous for the occupants. The NRG Link greatly simplifies the whole process and when installed according to very simple instructions it makes the system completely safe and very cost-effective.

NRG Link is ready to install design reduces an average dual-pressure heating installation time by a days work on more and costs less than the cost of the components, plus assembly time (layout, measuring, cutting, soldering, etc.)
