What does an optimiser do?

Optimisers remove the uncertainty of what time to set your heating ‘on’ time in order to ensure the desired room temperature is reached on time, whilst ensuring fuel isn’t wasted bringing your house up to temperature too early.

Example:

Most households requiring a comfort temperature of 21°c at 7.00am would typically set the central heating programmer for 6.00am. On particularly cold days, the house may not be hot enough by 7.00am and on a more mild day it may be hot too soon, which means some energy could have been saved.

You simply set an ‘Optimising’ Room Thermostat to deliver your comfort temperature at your desired time and each day it will calculate the optimum time to switch the boiler on, ensuring the temperature you want when you want it and the best use of energy each day.
