Cylinder support

The award winning Baxi Customer Support team don't just provide excellent aftersales support for our boilers, they also provide aftersales support and engineer services for Heatrae Sadia cylinders,  including warranties, protection plans and ad hoc repairs.

All Baxi Customer Support engineers are trained to repair or service Heatrae Sadia's domestic cylinders, providing essential protection for your heating system.

Cylinder repairs

With a first time fix rate of over 95% and access to over 250 manufacturer trained engineers, you can trust Baxi with your cylinder repairs. You can purchase a protection plan to cover the initial cylinder repair and then further protect your product for the following 12 months, covering any new faults that may occur; if a repair is not possible on the engineer visit, you will be given a full refund.  One off repairs are also available for your cylinder without the additional 12 months cover.

Cylinder warranties

Protecting your cylinder with one of our warranties will provide you with complete peace of mind during the warranty period. Register a warranty.
