Introducing Herschel InfraSense
Herschel InfraSense control, integrated into each Halo heater, uses advanced technology to enables large spaces like churches with high ceilings to utilise temperature control. Previously, it has been impossible to control heating in large volume spaces using a thermostat as it measures air temperature rather than reading the radiant temperature.
InfraSense precisely maps and measures the average radiant temperature of the heated zone under the heater, every second. Using smart algorithms, InfraSense automatically adjusts the power level of the Halo to ensure desired target temperatures are accurately maintained without over or under-heating. This maximises comfort levels and saves energy. You can be confident that the congregation will be heated to the desired temperature and electricity is not wasted from heaters being at a higher power than is required. No other system can achieve this level of control and energy savings.
Only available for Herschel Infrared systems. UK Patent Number GB2631160
See how InfraSense works
This animation shows how InfraSense works when zonal heating using Halos in Heritage buildings.
Simple to Use Control Tablet
Heaters can be controlled individually or grouped into zones. The InfraSense touchscreen central control is extremely easy to use with the option of one touch manual power level selector (low, medium and high) or intelligent automatic mode to set and control a temperature. Lighting is also controlled via the central controller. It communicates wirelessly with the Halos and can be located securely away from public areas. An optional passcode prevents unauthorised use.
Revolutionising Heritage Heating
Conventional church heating controls measure the air temperature. In large buildings with high ceilings, this results in the heat rising to the ceiling and leaving the lower areas feeling cold. InfraSense has completely revolutionised the way we heat heat heritage buildings.
The intelligent control system avoids having to manually monitor and adjust power levels during a service with it’s automatic mode. Each heater will independently measure and heat their zones, without the risk of overheating, so each area of the building will have the same level of comfort.
InfraSense also features manual control for manual selection of Halo power levels.

Experience the future of church heating today
InfraSense maximises the life of the Halo heating emitters via automatic load balancing. Herschel provides remote access and support from our UK based national service hub. The system is future proofed with remote updates to the control system possible. Future developments include App control, integration with time of use electricity tariffs/solar, energy use reporting and presence detection.
We also offer manual control options, please contact us for more details.
Frequently Asked Questions
InfraSense incorporates a simple to use touch screen control tablet ensuring users can easily control the heaters in the space. The touch screen enables InfraSense’s intelligent automatic mode, allowing the Halo heaters to automatically adjust power levels to keep the temperature consistent in each zone. This feature allows you to avoid having to manually monitor and adjust power levels during a service. If you did want to manually control the heaters, then the touch screen control tablet can be used to easily choose your zone, then select the desired temperature. We are also happy to provide additional advice over the phone or email to assist in any way required.
InfraSense offers an unrivalled level of control and flexibility for heating large spaces. Some of the benefits of InfraSense over other systems are:
Temperature Reading
InfraSense scans the heated zone every second and is constantly measuring the radiant temperature. As infrared heats people and objects directly, this offers a much more accurate and efficient way of measuring comfort levels as opposed to measuring air temperature. The radiant temperature is also a more accurate reflection of how warm people are.
Automatic Heating
InfraSense allows you to ensure every single occupied area in the heritage building is being gently warmed to the same level. If one particular area of the building is typically cooler than others (e.g., if it is by a door or window), the InfraSense system will be able to detect this and adjust its power levels accordingly. Contrastingly if an area takes less time to warm up, the InfraSense will detect this and lower (or turn off) its power levels where need. These automatic adjustments not only maintain a consistent level of comfort throughout the building, but also ensure no areas are being under or overheated, resulting in the heaters running the most efficient way possible.
Remote Updates
We are constantly developing our InfraSense system, introducing new and exciting features to help you heat your space in the most efficient way possible. The InfraSense system is connected to a local network that we provide during the set-up, this ensures the system is always connected to the Internet (even if your building does not have WiFi). This allows us to send remote updates to your InfraSense system, unlocking new features for you to use on your touch screen control tablet, meaning you will always be up to date with the latest versions and added features.
No, InfraSense is a wired system that does not rely on internet connection. There will be an option to connect to the internet using either a supplied sim card for data internet access or your own wi-fi router using an ethernet cable which will allow us to provide remote support and future updates to the controls.
