Interseasonal Heat Transfer™

After completing an IHT installation, including connections to the Building Management System of the building, and full testing ICAX provides training to help you achieve the optimum performance of the IHT system in use.

ICAX provides telemetry to monitor the IHT system remotely. This is used to refine the system parameters if the use of the building in practice differs from the predicted use at the time of design.

ICAX can provide a record of the heating and cooling energy use of the building if you would like this service. Knowing the energy use in the building can help to save energy in use, and can highlight issues if the energy loads on the building differ from the predicted use at the time of design. With the help of remote telemetry we can provide direct monitoring of the way the IHT system is used in a particular building: this enables us to match the system more closely to the design criteria of the building and provide advice on how to use the building more effectively and more cheaply.

We can also monitor and report on other key data (such as lighting and small power electrical consumption) that will enable you to claim additional BREEAM points.

Maintenance for lifetime support of IHT Sysytems

ICAX maintenance programmes include the monitoring, quality control, data collection, maintenance and consulting functions needed for lifetime support of ICAX systems.

ICAX monitors and logs the performance of IHT systems for the purpose of reporting to clients. This data may be used for contractual reasons and to enable to payment of external grants such as the Renewable Heat Incentive.

Carbon Offset achieved

We can provide a data output feed to report on the carbon offset achieved and energy used to a screen within the building. ICAX is providing this service to Merton's new Intergenerational Centre.

We provide maintenance contracts to ensure that the IHT system and all equipment continues to operate as designed. We provide annual licences for the software and Energy Management System incorporated into the ICAX Skid to ensure that your system is up-to-date and tuned to the way your building is used.

Invisible heating systems

IHT systems are automated. Because they come with low maintenance, low running costs, low noise and are out of sight, IHT systems are often referred to as "invisible heating systems".
