Use this feature to add an estimated amount of heat loss to your heat pumps power output. For example, if your room has a permanently open door, staircase, large glass skylight, kitchen, anything that will drain heat from your room. Slide the "Room Heat Loss." to add heat (20-30% is the most common allowance)
Room Width, Length and Height
Room dimensions are in meters.
You have several options if your room is not square.
Work out the M3 manually and multiply that by the Watts required per M3.
You can work out the areas separately and add the required KW together.
With triangles, you can half the long edge and multiply that by the height.
Example of halving a triangle in a typical Chapple ceiling
As a Chapple ceiling is a triangle, just divide the triangle section in two and add the wall height. Use this measurement B in the "Room Height".
