Warm Air & Radiant Heaters - Optimising Controllers Radiant Tube

Optimising controllers realise fuel savings by adapting the heater firing and heat distribution pattern to match variations in heat demand. They are available either as stand alone units for retrofitting to existing heaters, or as modular units that can be integrated into heater or other control systems.

Optimising controllers sold with radiant heaters as part of a package will be eligible for Enhanced Capital Allowances. The minimum features for optimising controllers are tamper-proof, independent zone, timing and temperature controls such that each functional area can be separately controlled in accordance with occupation patterns. The controller must also include facilities for users to “temporarily override” pre-set timings during unusual occupation hours, “automatic night set back” that turns the heating on to prevent condensation and frost damage, and the use of radiant sensors. Manufacturers must provide a detailed product specification of the controllers.

Standalone optimising controllers for retrofitting to radiant heating systems also qualify for Enhanced Capital Allowances provided they fulfil the minimum requirements for controllers listed above.

Where optimising controllers are sold as an integral part of a larger control system offering facilities such as lighting control, building security, fire or lift management, or process control; only the cost of purchasing the controller and incorporating it into the larger system are eligible for an Enhanced Capital Allowance. Such claims must be based on actual costs and are subject to the following maximum claim values:
