Compliance with LOT20

Lot 20 is EU Ecodesign legislation for electric heating.  Effective from January 2018, all installations must comply with this minimum efficiency standard. The focus is on removing poorly controlled heaters from the market and replacing them with controls for temperature, timer, presence and open window detection amongst others.

The important part to understand of this legislation, is that heaters fitted with basic controls will no longer be permissible, but that doesn’t mean the control unit has to be integrated.

The Prefect Irus central control system and ecostat 2 range of controls are supplied with a bespoke slave heater. This option provides control through an impressive range of features. The specifications required under EU law are far exceeded and these master controls, fitted separately from the panel.

Our unique, patented, Energy Lock is supplied with the controller and simply slips into a slot on the heater making it operable.
