1.1 Operating the Boiler
The Central Heating and Hot Water you need will be
available when the gas and electricity supplies to the boiler
are turned on with the timer and other heating controls in
your system set correctly.
Other heating controls are items such as room
thermostats, cylinder thermostats and thermostatic
radiator valves. To give the most energy efficient
performance these controls can switch your boiler
on and off even when your timer is on. Instructions
on how to use your programmer and other
heating controls should have been supplied with
the items. Baxi Heating UK Limited also produce a
guide ‘How to get the best out of your NEW
Central Heating System’. Telephone our Literature
Hotline on 08706 060 623 to request your free
copy.
