All new energy efficient boilers often feature smart thermostats or programmable timers. If you have opted to go for smart controls the heating engineers will set up the smart thermostats allowing you to control your central heating by your phone or tablets. This can offer convenience for turning the central heating on or off at any time to suit you, which can also potentially cause energy savings. If you opt for a manual thermostat, the heating engineers will explain and go through the controls to maximise your comfort and energy efficiency.
