BEN

Balanced Energy Networks

 

A Balanced Energy Network is a new form of district heating that circulates water at near ground temperature to each building on the network to allow each building to use its own heat pump to extract heat for heating, or to reject heat when it needs cooling.

The original BEN Project created the first BEN at London South Bank University with the help of funding from Innovate UK. The BEN Consortium, led by ICAX Ltd, is now able to offer to design and install Balanced Energy Networks for those who want to save energy, save costs and save carbon on an efficient flexible clean district heating network.

The advantages of Balanced Energy Networks

The advantages of Balanced Energy Networks are that they:

A Balanced Energy Network can serve new buildings and existing buildings

High Temperature Ground Source Heat Pump

A BEN can serve new buildings that are designed to be heated by heat pumps using modern heat emitter systems such as underfloor heating, or air handling systems, that require lower flow temperatures of around 40°C.

A BEN can also serve older buildings that have been designed to be heated using heat emitter systems that require flow temperatures of 80°C to work well, such as radiators. In these cases it will be appropriate to specify high temperature heat pumps that are capable of delivering temperatures of 80°C in order to avoid the disruption of renovating the building with modern heat emitting systems.

Demand Side Response

Where heating uses electricity from the Grid to power its heat pumps there are opportunities to benefit from Demand Side Response. The control system for the heat pumps can be linked in to an demand side aggregator who is able to provide a lower cost of electricity if the heating system is tuned to respond to changing price signals from the Grid in real time.

Smart Hot Water Storage

Where demand side response is in place there are opportunities to exploit this further when thermal energy storage is also available. Large insulated water tanks can be used to store heat that has been generated with low priced electricity for use at peak times.

Renewable Heat Incentive

The Renewable Heat Incentive is a grant system from Ofgem that is paid over 20 years for newly installed renewable energy systems. The largest rates are available for heating systems that do not rely on combustion: heat pumps and solar thermal panels.
