The Smart Cellar System

Cellar chilling costs average £3,000 per annum. By installing our Terra Smart Controller and one of our Terra Smart Remote units it is possible to save in excess of £1,100 per annum.

Terra Smart Controller Advantages

Plug and play control box

30% + saving in main cellar cooler costs

Switches off main cellar chiller between 12pm and 8am and peak electricity cost hours (4 – 7pm)

If cellar temperature increases to or beyond 17 degrees, sensor detects and switches chiller back on

Beer is maintained at all times at the recommended 12 degrees.

FYI beer in the keg increases in temperature at a much slower rate than the surrounding temperature.

Annual savings of £1,100+ per year

There will of course be a difference in the amount of electricity used to chill the cellar dependant on the outside temperature. The duty cycle of a chiller will be far higher during the summer or warm period. Therefore, when trialling the system with both Whitbread's and Marstons the outside temperature was split into three different “seasons”. The actual savings for all three periods were between 23% and 54% averaging out at 35%. Full Evidential back up figures and reports are available on request
