According to the Carbon Trust, heating can account for as much as 60 % of total energy use, yet a large proportion of the energy consumed by heating is likely to be wasted due to incorrect control settings. Notably, lowering heating temperatures by just 1º C can save 8 % on fuel consumption, and heating costs can increase by 15 % or more if boilers are poorly operated or maintained. Optimum heating systems can lead to significant cost savings.

Weather compensation adapts heating systems to the changing weather. It uses automatic controls that adapt indoor heating according to outside air temperature, and therefore reduces inefficient heating and provides savings. Installation costs for weather compensation systems are usually recovered after a couple of years.

Weather compensation systems reduce the water temperature in the heating system as the outside temperature increases. It works by using an external thermostat (set away from vents, obstructions, sun, and open windows). During milder weather, the weather compensation control adapts the boiler's water flow temperature, thus saving energy.
