Boiler Plus Energy Mesures Explained
A device, or feature within a device, which maintains the temperature inside the building by sensing and limiting the temperature of the water circulating through the heat generator and heat emitters in relation to the temperatures measured outside the building.
(SAP 2012) – note that devices drawing weather data from the internet also comply.
A device, or feature within a device, which adjusts the temperature of the water circulating through the heating system according to the temperature measured inside the building.
Flue gas heat recovery
When fitted to a condensing boiler a flue gas heat recovery system (FGHRS) recovers heat from the flue products to pre-heat the domestic hot water supply.
Smart Control (automation & optimisation)
Smart controls offering load compensation or whether compensation would be fully compliant with the new standard:
Automation is a function that allows the device to automatically control the heating system output in response to programmed demand or occupancy detection. Advanced examples detect where householders are, such as through sensor data or geolocation based on smartphone data.
Optimisation means the device calculates how long it takes the property to reach the desired comfort level, and times the system’s operation to minimise the amount of work it has to do. Usually, it also modulates the output of the boiler in a similar way to load compensation, so as little fuel as possible is consumed.
