Hello out there to you wonderful knowledgeable people!

I am looking at heaters, electric ones to be mounted in a few different rooms in my house. (House does not have a central heating system). I have been looking at baseboard heaters as well as forced air wall mount heaters (which are about double the cost of the baseboards I have noticed... )

So, here's the question. I see all of these different baseboard heaters, all in a variety of legnths and each heater has a few different numbers on them... numbers like 500w/240v, 750w/240v, 1000w/240v, up to 2500w/240v... I understand 240v, but the different wattages, obviously a 2500 watt heater is going to heat more than a 500 watt heater, but really, how much more?

So the question:

How much area can these heaters heat adaquately? Like 500w do 300 sq ft, 2500w do 3000 sq ft? This is what I am not sure of, I want to ensure that I get the proper heaters for the space needed.

I have 2 bedrooms, 1 washroom and a large living area. Kitchen and dining room (open concept) to heat...

A Watt is the product of current times voltage, and indicates the amount of energy consumed or produced by an appliance. So you can have a heater of 500w/240v, and of 500w/120v. Different voltages, but the same amount of energy.
And a 2500w heater produces 5 times more heated air than a 500w heater.

As to how many watts and heat per how many square ft : impossible to say, as there are other influences, like height of ceiling, isolation of the walls and windows, chinks, outside temperature, doorclosing habits, etc. : a watt is a watt. The more watts you have, the more heat is produced. Most heaters have a thermostat controlling the heat released. So the wattage is in many cases more an indication on how fast you can raise the temperature in an area. The more watts, the more control you have.

Forced air heater have the advantage of a quick temperature raise in specific places.

Hope this helps !

Here is a online calculator.

Awesome good stuff guys, thanks...

Now.. understanding BTUs?
