The watt is a unit for power is one of si units.
Btu from 1500 watt heater.
Its name is in honor of the scottish engineer james watt the eighteenth century developer of the steam engine.
Therefore 1500 watts 1 5 kw and 1 5 kw x 3413 btu kw 3 413 1 5 5 119 5 btus per hr for a 1500 watt heater.
When sizing a heater the rule of thumb is to allocate 10 watts of heat to every square foot.
Now that you already know how to calculate watts in btus let s now look at how many btus are needed to heat your home or more specifically how many btus are needed for just one room.
It generates 1 500 watts of electricity per hour and produce 5 100 btus of heat.
1500 watt w.
Take the btu figure you calculated in step 2 when purchasing or comparing heating systems.
What is the electric cost.
Answer 1 kw is 3 413 btus.
So we multiply 1500 watts by 3 41 and the end result is 5115 btus of heating power.
Factors that affect how many btus needed to heat a room.
The unit symbol for watt is w defined as one joule per second measures the rate of energy conversion or transfer.
If we go back to our 1 500 watt heater which puts out just over 5 100 btus it should be enough to heat a room of 150 square feet.
The 120 volt 1 500 watt heater offers an easy way to heat a small space.
A standard 1 500 watt electric heater produces 5 115 1 500 times 3 41 btu per hour.
In other words to heat a room of 100 square feet you will need a heater that is 1 000 watts which translates to 3 410 btus.
One 1 watt is equivalent to 3 41 btu.
5118 21245 btu pre hour btu h watt.
This means your 1 500 watt power heater will produce 5115 btus per hour.
