are many factors affecting the SAP Rating of a building.
A significant factor in improving the SAP Rating is the
type of supplimentary heating provided.
Fires, either gas or woodburning, which take combustion air directly from the outside, eliminate the need to provide ventilation within the room:
|Modern woodburning fires
improve SAP Rating in a number of ways. Woodburning is
both environmentally friendly, being carbon neutral and a
genuinely renewal fuel. Wood, therefore, reduces the SAP
Rating. Woodburning fires now offer efficiency up to 80%
again a SAP rating improvement, and the new generation
have the facility to take their combustion air directly
from the outside creating what is, in effect, a
woodburning "balanced-flue" fire.
With a self-cleaning glass door sealing the fire from the room, no additional air is needed to be provided, resulting in a SAP Rating improvement due to the absence of ventilation.
The Barbas Energa shown right and is typical of the latest generation of woodburning fires:
|The Barbas Energa
features a Ceramic Particulate Filter for removing fine
particles from the flue gasses.
As shown in the drawing (right) ambient air is drawn into the fire at the bottom - possibly directly from the outside - and is pre-heated as it travels to the top of the fire. This hot air enters the combustion chamber where it provides oxygen for combustion.
The resulting flue gasses travel upwards, passing through the white ceramic filter before being exhausted via the chimney.
Absolute control of the fire is effected by the slider control (inset)

|Balanced-flue Gas Fires & Stoves|
|Balanced-flues are almost universal these days for central-heating boilers but they are becoming a popular feature of the latest gas fires. They can be fitted with the flue through the wall in the familiar way but can also use an existing chimney with the fumes being exhausted up the chimney and combustion air being drawn down the chimney via twin liners. As with the Woodburning fires above, these balanced flue gas fires offer a significant improvement in a house's SAP Rating.||If a stove is the favoured source of supplimentary heating, there is a choice of traditional and contemporary balanced-flue gas stoves. Depending on model, the balanced flue can terminate through a wall or roof. Balanced flue gas stoves offer high efficiency and the same SAP Rating benefits as the other fires featured.|
