Yes, spot heating in zones of larger areas, is a major advantage of infrared heating systems. You can strategically place heaters above workstations or desks, minimizing waste by not heating areas you don’t need to and cutting operational costs.

No, you don’t, infrared heating in large commercial spaces targets objects and people directly, rather than heating the air volume. This allows for zoned or spot heating of areas where only occupied or high-use areas are warmed. This greatly improves energy efficiency as you are not heating the whole volume of the space but are focussing on heating and controlling the comfort levels for people below where heaters are mounted.

Absolutely, electric infrared heaters integrate well with Solar PV and battery systems. This combination can significantly reduce your energy bills and carbon footprint, especially if usage is timed with peak solar generation, off peak electricity rates and time of use tariffs.

Our heaters are simple to install by any certified electrician or installer who is familiar with infrared heating in commercial buildings to ensure: 

• Proper sizing and positioning of heaters and cabling  

• Electrical safety compliance and certifications 

• Integration with controls or BMS 

Please contact Herschel if you would like us to recommend an electrician.

Costs vary depending on: 

• Size and number of zones/heaters 

• Control system complexity 

• Mounting type (ceiling, wall, suspended) and any access equipment required 

• Installation costs in your region 

• Any requirement to upgrade the electrical supply to the site 

A proper site survey from a recommended commercial electrician, like InterRay, who are part of the Herschel group of companies, will give an accurate quote.

Minimal disruption is involved, and installation is generally straightforward. Planning routes for electrical cables to connect the heaters and control system to the electrical distribution boards will be key considerations. Often, access platforms or scaffold will be required to run the cabling to the required positions. 

There is no ductwork, gas or oil connections or wet systems involved.  

Work can often be scheduled outside key working hours or at weekends and phased over a period to minimise disruption. 

Wall or ceiling-mounted infrared systems in commercial spaces are quick to install in comparison to convection and central plant systems like heat pumps.

Commissioning typically includes: 

• Power connection and safety checks  

• Configuration of controls, sensors, and timers to follow the requirements of the end users 

• Testing all zones to ensure effective operation 

• Training for staff or facility managers on usage and control 

• Obtaining the installation certificates from the installer 

It depends on the system size, type of heaters selected (for example our Vulcan heaters require a 3-phase supply) and the overall number of heaters. 

For small to medium size installations and spot/zone heating of smaller areas, often a single-phase is sufficient. 

However, for larger commercial spaces with high heating demand and where other electrical appliances/machinery is being used: 3-phase may be recommended to spread the electrical load more efficiently across the phases.  Please consult your electrician who will be able to advise.

Electric Infrared heaters have very low maintenance: 

• There are no moving parts or fluid systems 

• Occasional dusting or cleaning of heaters may be required when they are turned off if there is significant wood dust or similar materials that could rest on the heaters. Ensuring a fully operational extract system in these spaces will be important.    

• Control systems may need firmware or software support updates 

• No annual servicing like boilers is required although an annual check on the system via the offsite controls or an onsite review of heating elements and connections could be included as part of a maintenance package

No, each unit can be wired to operate independently.  Heater elements have a typical lifespan of between 7-10,000 hrs depending on use.   

Any fault in one heater can be isolated and replaced/repaired while the other heaters continue to operate.  

Modular design of elements within heaters, allows for quick replacements or repairs on site enabling elements to be changed easily and quickly.

This is possible depending on where you are. 

• Government or council-level grants (e.g., energy efficiency or carbon reduction schemes) may apply. 

• Eligibility depends on your location, building type, and may require the use of renewable integration (e.g., Solar PV). 

Check with your local council, combined authority or an energy advisor. Business Energy Scotland, Salix, or BEIS may have current schemes.
