How to calculate the BTU size Portable air conditioner that Cool or Cozy Rentals can supply.
If you have any further questions,
contact us direct or email us through the web where you will receive a quick reply,
and for the gas heater sizes for your situation,
on the bottom of this page are the room sizes gas heaters will keep warm.
Food for thought #
Just
think
if you rent/hire a portable air conditioner and you have rented
the goods for three months now, your rent is halved, now it
must be Autumn or near too, now in Perth we still have those
occasional hot days and nights, so you keep the goods for another
month, then all of a sudden there's that cold day, well you can
use the heating side of the portable air conditioner(if applicable)
until it can't keep up with the cooler weather you can swap it for
a heater in our range and pay half price straight away. You can
choose a gas heater, oil heater, ceramic heater or one of
those electric portable fire places with realistic flames. Then
guess what, the days start to get warmer again, then swap
the heater for that portable air conditioner again but start
paying half price right of the start. If you think you can find
a better deal in Perth please let us know, we don't think you
will.

All of our gas heaters come with hose connector to the bayonet on wall, most are 1.5 meters but we have some 3 meter hoses.All installations come with a demonstration on have to use the gas heater.Some heaters come with 24 hour timers and/or a remote control.
How to calculate your portable air conditioning needs.
OK, I'm going to take you through this process the simplest way I now how.
So most people don't know what BTU represents, it's British Thermal Units(BTU) or sometimes the units only have there rating in Kilowatts(KW). 1KW equals 3,412 BTUs.
So depending on a few factors in your circumstances, we can measure the heat load in your area.
FACTORS BEING:
The floor area of the room/s.
The size and position of windows, and whether they have blinds,shade or tint.
The number and size of room occupant/s.(if any)
The heat generated by electrical equipment or cooking area.
The heat generated by the lighting in room/s.
CALCULATING FLOOR AREA OF ROOM/S
The amount of cooling depends on the area of the room/s.To calculate the area do the following:
Length(meters) X Width(meters) then that answer is X with 337 which will give you the BTU area.
Room Area BTU = length x width x 337
POSITION AND SIZE OF WINDOWS
If the area you need cooling has no windows ignore and go to the next step.
If there are windows don't forget to calculate and factor in BTU.
North or West facing windows for the Australian conditions.
Length(meters) X Width(meters) then that answer is X with 870 which will give you the BTU for that window.
South or East facing windows for the Australian conditions.
Length(meters) X Width(meters) then that answer is X with 165 which will give you the BTU for that window.
If there are no blinds,curtains or tint, your window BTU needs to be X by 1.5.
Now, add all the windows BTU together, then X it by 1.5 if needed and that's your window BTU.
Window BTU = length x width x 870 north/west x 1.5(if needed)
Window BTU = length x width x 165 south/east x 1.5(if needed)(add the two together if needed)
Total Window BTU
OCCUPANTS
Most people forget about the heat we produce as humans,
An adults BTU = 400 and children BTU = 200 so add up all human BTU
Occupant BTU = adults x 400 children x 200
EQUIPMENT HEAT AND KITCHEN HEAT BTU
OK,there is much heat generated by the electrical equipment.Did you know a plasma/lcd televisions are so hot, have you notice the heat difference.
This is the hardest part of the working out, have a look at the electrical goods in question, and somewhere there will be a maximum power consumption rating.Add all the electrical goods up, then X it by 3.5 to give you an answer.For a kitchen all you need to do is add 4000 for the average.
Electrical Equipment and Kitchen BTU = Total wattage of room/s equipment x 3.5
LIGHTING
Take the total wattage of the lighting(check the globe or tube for wattage printed on it) and multiply by 4.25 to give you a total BTU for your lighting.
Lighting BTU = Total wattage x 4.25
TOTAL COOLING REQUIRED
Add all the BTUs you have collected
Total heat load = Total Room area BTU + Total Window BTU + Total Occupant BTU + Total Electrical and Kitchen(if needed) + Total Lighting BTU =.................
The total BTU figure you have is the amount of cooling BTU you will need in one portable air conditioner unit or you may need two units to fill the total BTU need for cooling.
DISCLAIMER:These calculations are a rough guide line only.Complete accuracy can't be achieved do to changing conditions.
Room Sizes for portable gas heating
The figures below are for minimum room size for heater and maximum room size heater will keep warm.
The convection heaters we stock have an electric heater up to 2000watts for those really cold mornings.
