Based on 4th generation technology the Ultracom sxi is built with tried and tested components providing you with proven reliability, exceptional efficiency and ease of installation including being able to install and commission the appliance without removing the case.

The stylish orange backlit controls can provide 7 day or 24-hour control for hot water and central heating. The simple push button controls and copy and paste functionality mean that it takes seconds to set and alter any programmes, providing the homeowner with as much or as little flexibility as they need.

Note: The Ultracom sxi's inbuilt digital controls can be activated as required by fitting an options board to the boiler. This must be purchased as an accessory in addition to the boiler.
