The installation by EAC Services (Guildford) comprises a 95 kW 2-pipe SMMS heat-pump system with three supplementary 12/14 kW split systems. The nine ceiling cassettes are group controlled by the Toshiba Interactive Intelligence control system.
The outdoor units are at the rear of the store. Although they are very close to neighbouring houses, there have been no complaints of disturbance.
