Performing heat loss calculations on a structure. How to calculate the heat loss for a structure. To calculate the size of heater(s) required to heat a structure. The temperature to be maintained within the structure. The lowest ambient (outside temperature) which can be expected for the. The direct heat loss from the overall surface area of the structure.

Heat loss through natural or mechanical ventilation. The difference between the ambient and internal temperatures gives the. Temperature lift = Internal temp. Putting a value on this can be very difficult. Total heat loss = total surface heat loss x allowance for heat loss. Finally to calculate the heater size needed, the total heat loss.

Heater size required = total heat loss x temperature lift. Example heat loss calculation (see diagram)Temperature lift = 2.

CArea of roof = 2 x 5. Area of walls = (2x. Area of floor = 3.

Heat loss through roof = 3. WHeat loss through walls = 1. WHeat loss through floor = 3.

WTotal surface heat loss = 2. WAssuming 2. 0% for heat loss through ventilation. Total heat loss = 1. WHeater size required = total heat loss x temperature lift. WIn this example 4 - 2. W Activair Ace electric fan heaters.

Cost is $300, or $60 for students -- just think how much energy would be saved if this program was made free.

W Activair portable heaters or. W Activair wall mounted electric. Calculating heater running costs per hour.

Calculating the running cost per hour for an electric heater is. Electricity is sold by the unit (k. Wh), multiply this by the. W. Running cost per hour = heater size (k.

W) x unit cost of electricity (k. Wh)Estimating annual heater running costs. Annual running costs will be greatly affected by physical and. U values of building materials. The above should be considered.
