What is House heat loss calculator?
A house heat loss calculator is a useful tool for homeowners to determine the heat loss in their homes. By knowing how much heat their homes lose, homeowners can take steps to improve energy efficiency and save money on heating bills. In this section, we will explain the formula used in a house heat loss calculator, provide an example, and answer some common questions about this tool.
Formula used in House heat loss calculator:
Q = U x A x (Ti – To)
Where: Q = Heat loss rate (Watts) U = Overall heat transfer coefficient (Watts/m2K) A = Surface area of the wall, ceiling, or floor (m2) Ti = Inside temperature (°C or K) To = Outside temperature (°C or K)
Example: Let’s say you want to calculate the house heat loss rate for a room in your home. The room measures 4 meters by 5 meters with a ceiling height of 2.5 meters. The temperature inside the room is 20°C, and the outside temperature is -5°C. The walls are made of wood with an R-value of 0.9, and the windows have an R-value of 1.5.
To calculate the overall heat transfer coefficient (U), we can use the following formula:
U = 1 / (Rwall + Rwindow)
Where: Rwall = R-value of the walls Rwindow = R-value of the windows
So in this case, U = 1 / (0.9 + 1.5) = 0.47 W/m2K
The surface area (A) of the room can be calculated as follows:
A = 2 x (4 x 2.5 + 5 x 2.5 + 4 x 5) = 57.5 m2
Using the formula, the heat loss rate (Q) can be calculated as:
Q = 0.47 x 57.5 x (20 – (-5)) = 2,107.25 Watts
Therefore, the heat loss rate for this room is 2,107.25 Watts.
