How do controls affect ErP?
The ErP Directive covers all products that consume energy, such as boilers, heat pumps, solar thermal etc. It also includes controls, which are defined using 'classes'. These run from Class I (a simple on/off room stat) through to Class VIII (multi-sensor room control for use with modulating heating appliances). Each control class equates to a certain percentage uplift in system efficiency e.g. A class VI weather compensating control and room thermostat, such as the Worcester Wave, will add 4% efficiency to the heating system.
