What to do if my STIEBEL ELTRON Heater room does not get warm enough?

If the room is not getting warm enough, start by checking the RCD and the fuse/MCB in the fuse box to ensure there is a power supply. Also, overheating may be the issue. Make sure to remove any dirt or obstructions from the air inlet or outlet and ensure you observe minimum clearances. Finally, address any heat losses by closing windows and doors and avoiding constant venting, as the heat demand of the room may be higher than the appliance output.
