The NRG ZONE has been designed to eradicate many of the issues being faced within today’s ever-changing heating industry.

It has been developed to increase the safety, efficiency and reliability of any system it is installed in while decreasing the systems complexity and installation time.

The NRG ZONE benefits are universal and apply to all involved in the heating industry, from architects, heating engineers, plumbers, right through to the end user.

Heating systems (such as sealed or open configurations, high-temperature appliances; gas or oil boiler and/or geothermal equipment; heat pumps etc.) can all be used to their highest potential with proper, well thought-out installation system layouts.

The 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 circuit from a solid fuel appliance that incorporates an open expansion and cold feed to take the heat from the solid fuel appliance into the sealed system. The unit is completely insulated with pre-wired primary and secondary side pumps which are controlled by an integral thermostat, and plate heat exchanger all neatly packaged in a 320 mm x 330 mm x 350 mm, including pre-insulated enclosure.

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.



The NRG-LEX SYSTEM CONTROL MODULE eliminates the tedious and complex wiring tasks associated with a modern central heating system. The module links all the electrical components in a simple and efficient way.


4 temperature control zones, each with time and temperature control inputs as well as LED indicators, which can control a circulation pump or motorised valve.

2 boiler control systems (linked to the 4 temperature control zones), each with 3A power supply and volt-free switch contacts, to switch power supply to boiler(s).

2 auxiliary relays, activated by any of 4 inputs, and each with normally-open and normally-closed contacts.

1 frost thermostat input to activate boiler relays when the ambient temperature gets dangerously low.
