Horstmann BX2000 Water Heating Boost Control

This simple boost control is intended for use with electric water heating systems where the immersion heater(s) are controlled by the Electricity Company's Radio Teleswitch, Radio Telemeter or Tariff time switch. The BX2000 allows the user to 'top up' the hot water if extra supplies are needed during the day time with the main water heating taking place overnight using off peak electricity.

• Makes the most effective use of the latest cheap-rate tariff structures, electronically
• 1 hour or 2 hour boost
• Always gives priority to off-peak supply
