# How much does it cost to run a 5000 watt electric heater?

3. To estimate hourly running cost, multiply the input power in kW by the price of your electricity per kW hour. For example, if you pay 7.53 cents per kWh and you run a 5,000 watt or 5kW heater you would multiply 7.53 cents/kWh x 5kW x 1 hour = 37.65 cents per hour to run the heater.

Besides, how many BTU does it take to heat a 2 car garage?

A basic rule of thumb for forced-air heaters is 45,000 Btu to heat a two- to 2-1/2 car garage, and 60,000 for a three-car garage. The makers of low-intensity infrared tube heaters say that 30,000 Btu can heat a two to 2-1/2 car garage, and suggest 50,000 for a three-car garage.

Are propane heaters safe for garage use?

Yes, you can use a propane heater in a garage. There are only two main stipulations: it must have adequate and combustion air to operate, and you have to keep it away from flammable materials. There are some portable propane heaters that can be used indoors with a disposable propane tank.

What size of heater do I need for my garage?

The quickest way to estimate the size of your garage heater is to follow the basic rule of 10 watts per square foot of space. If your garage is 24 ft. x 24 ft., for example, it has an area of 528 square feet (24 * 24 = 528) and would require a 5280 watt garage heater (528 * 10 = 5280).
