Information On Room Ventilation: Some homes have greater air leakage with gaps in windows frames, floorboards and ventilation through chimneys and air bricks; other homes are very air tight and use an MVHR system to achieve the required air changes in a room without losing much heat. Horizontal radiators are measured by length. In calculating the heat loss in watts for the whole room, Ive discarded the internal walls (on the basis that the temperatures either side of the walls will be the same) and broken down each of the remaining surfaces (walls, ceiling part of which is a warm roof, floor, windows, door) into their constituents parts, and assuming a temperature delta of 22C, Ive calculated the U-values of each surface.
