According to Cadet support, they recommend 8-10 watts per square foot when electric baseboards are used as a primary heat source. And 6-7 watts per square foot when they are used for supplemental heat.
Calculating the Right Size Hydronic Baseboard Heater
For example, a 10 x 10-foot bedroom is 100 square feet, (10 multiplied by 10 = 100) which requires 3,400 BTUs (100 multiplied by 34 = 3,400). You'd need 5.6 feet of baseboard heater to heat the space (3,400 divided by 600 = 5.6). That's it!
In other words, a 1,500-watt heater will be great for a 250-square-foot room with central heat. If that same room had no other source of heat, you'd need a 2,000-watt heater.
So a 240-volt circuit running on a 20-amp, double-pole breaker, can have any combination of heaters up to 3,840 watts. For example, using just one thermostat, you can install: Two 1,500 watt heaters, or. Three 1,000 watt heaters, or.
Myth #2: Bigger is Better. The rule of thumb for sizing a baseboard, or any electric heater, was 10 watts per square foot. So if you have a 10 x 10 room you would need a 1,000 watt heater.
If you rely mostly on electric baseboard heaters to heat your home, they probably make up a big part of your annual electricity bill – sometimes as much as 44%. However, there are plenty of ways to maximize the efficiency of your baseboard heaters to cut down your winter heating costs.
In a 2,000 square-foot home, you may need around 250 to 300 linear feet of baseboard. The combined perimeter baseboard length will be about 180 linear feet. Internal walls will increase that figure by another 100 linear feet to a total of 280 linear feet.
Having one thermostat to control both heaters will work just fine because you're heating one larger space.
When placing multiple heaters on a circuit do not exceed the wattage listed for the corresponding wire and circuit breaker size. (For example: 2-1000W & 1-1500W, 240V heaters = 3500 Watts total. These 3 heaters would require 14/2 wire and a 20 Amp 2-Pole breaker if they were to all be placed on the same circuit.
Only the speed of heating will be more with 2000 watt. As far as the quanitity of hot water is same, you will need same heat content, for which same energy will be needed. For ex to provide 6000 Wh of heating, 1500 will take 4 hours and 2000 will take 3 hours.
So the 1500 watt will usually heat up to 150 square feet. Heating question - trying to understand what size heater to ...
Labor Costs
The average cost to hire a licensed electrician to install an electric baseboard heater is between $390 and $1,190. The average cost of an electric baseboard heater is anywhere from $25 to $200.
Find the area (length times width) and divide by 12 for linear square feet of each of your rooms because baseboards come in this measurement. Calculate for Each Room. Once you have the calculations for each room, add your numbers to find the total linear square feet for your entire home.
Many baseboard heating systems are a form of electric heat that operates without ductwork and can be expensive to run. Baseboard heating is often more efficient than radiators, and they are even more efficient when they are run constantly, instead of being turned on and off.
1) You can install a maximum of two 1000 watt heaters on a dedicated 15 amp circuit using 14 AWG copper wires or a maximum of three 1000 watt heaters on a dedicated 20 amp circuit using 12 AWG copper wires.
Maintain Clearance: Keep furniture at least 6 inches away from baseboard heaters. This prevents the blockage of heat and reduces fire risk.
This allows them to counteract the cold air radiating off the window glass, as well as the areas where the home's greatest heat loss tends to happen. Electric baseboards are individually controlled, meaning each unit — and therefore each room — has its own thermostat.
Stelpro B1002W Baseboard Heater 1000W, 47 1/2" x 5 7/8", 240 Volts, B-Series BRAVA Electric Baseboard with Rounded Corners, White. The video showcases the product in use. The video guides you through product setup.
Many baseboard heaters have their own thermostat, which connects to baseboard heaters in a single or multiple rooms. You can find the thermostat mounted on a nearby wall or by the door to the room. The easiest way to turn off the heat is to adjust the thermostat at least several degrees down.
Replacing baseboards in your home costs $1,100 on average, and most homeowners pay between $800 and $2,250. A pro will determine your final cost based on material, installation type, and size.
Multiply the perimeter of each room by the number of rooms to get a total linear footage. In general, for a 3000 square foot house, you might need around 800 to 1200 feet of baseboard, depending on the design and number of rooms. It's always best to measure each room for a more accurate estimate.
There is no universal baseboard height standard but typically you'll see baseboards in several common heights: Most common: 3-¼", 5-¼", 4-¼" Less common: 3-⅛", 4", 5", 5-½"
