What is the difference between ERP system labels and Boiler Plus?

The ERP system label enables the installer to aggregate products into a higher efficiency category i.e. a boiler and control can be added to achieve a higher system rating, this is different to Boiler Plus as specific measures are applied as listed for the 4 optional measures, this means a system label can be generated for all systems however that system may not comply with Boiler Plus.

For example a Logic Combi C fitted with an electromechanical timer would have an ErP label but would not comply with Boiler Plus without additional accessories e.g. weather compensation.
