Weather compensation systems
Weather compensation is a communication between the boiler and an outside temperature sensor. Weather compensation tells the boiler to alter the temperature of the radiators to match the extra heat loss caused by a cold day, leading to a more consistent, comfortable environment and savings on your fuel bills.
A programmer allows you to specify when the heating comes on to match your lifestyle and heating requirements.
With a regular boiler with a cylinder, you will need a two-channel programmer. One channel that allows you to program when the hot water is being produced and the other channel for the heating in the home
For a combi boiler, you only require a single channel programmer as its is only the heating that requires time controlling - your hot water is on demand anyway.
Smart thermostats are a smart technology that let you gives you greater control over your home's temperature via a smartphone, tablet or desktop.
The components of the smart system plug into your boiler and via your wifi communicate using an app. You will need a good wifi signal in your home and a specific heating system to allow this smart technology to work.
