How do you determine baseboard size?
Joseph Russell updates
Measure the length and width of the room, in feet. Multiply the length x the width to get the square footage. Multiply the square footage x 10, to give you the rough wattage of heating required for the room. Choose one or more baseboard heaters that total or exceed the required wattage calculation.

Keeping this in view, what size baseboard heater should I use?
The quick and dirty rule of thumb many electricians use is 10 watts per square foot. So if your basement is 1200 sq. ft., you will need 12,000 watts of baseboard heaters. When wired for 240-volt operation, a baseboard heater puts out 250 watts per foot.
One may also ask, how many baseboard heaters can I put on a 30 amp circuit? Find the total amperage by dividing the wattage by the voltage (a = w/v). The amperage draw for the three heaters is 18.75 amperes. These three baseboard heaters can be connected to a two-pole 30-amp breaker that is supplying power to the heaters with a two-wire 10-gauge ROMEX® cable-type wire.
Besides, how many baseboard heaters can be on a 15 amp circuit?
Currently there are 3 baseboard heaters (750, 1000 and 1500) 3250 watts total running on 2 tied 15 amp breakers.
How many linear feet are in a 12x12 room?
So the total linear footage of the 1 x 12 boards is found by multiplying 5 (boards) by 6 (feet) which equals 30 linear feet.

How much does baseboard cost per room?
Baseboard heaters use about 250 watts of power for every foot of length. In a 100-square foot room that is part of an older home, the baseboard heater will be approximately 5 feet long. In a newer home, it will be about 3 feet long.What is the going rate for baseboard installation?
Some might charge per hour (ranging from $50 to $100 an hour); some might charge per foot ($1.50 to $2 a foot). Either way, baseboard installation is the type of project a contractor should see in person before determining an accurate estimate. It's a tough job to ballpark over the phone.How do you measure trim for a door?
Door trim should be mitered at a 45-degree angle at the top; when measuring door trim, always take this into consideration.- Measure from the floor to the top of the door jamb on the inside.
- Make a mark on the trim piece at 80 1/4 inches.
- Set a miter saw at 45 degrees.
- Measure across the top of the door jamb.
How much quarter round is needed?
determine the perimeter of your room: add the length and width measurements together and multiply by two. Measure the width of each archway and doorway, and add together. subtract the total of the doorway widths from the room perimeter to determine the total required length of wall trim and quarter round molding.How do you calculate molding?
Divide the total number of inches by 12 to convert from inches to linear feet. For example, if your wall measured 40 inches in length, and you are installing molding on the top and bottom, 40 x 2 = 80 inches. Divide 80 by 12 to get 6.66 linear feet.Do baseboard heaters need their own circuit?
Baseboard heaters are in need of a dedicated circuit to supply enough power for proper functionality. The general rule of thumb is that baseboard heaters need a 20-amp circuit that requires a 12-gauge wire for either type heater.Are baseboard heaters expensive to run?
Cost. Electric baseboard heaters are relatively cheap and easy to install. At the time of publication, these units cost a few hundred dollars, or less, and eliminate the need for expensive duct networks throughout the home, making them much more affordable than furnaces or heat pumps in terms of upfront costs.How many square feet will a 80000 BTU furnace heat?
In the example above, using an 80% efficient furnace, the 2000 square foot home above would require a 100,000 BTU input furnace which will produce the necessary 80,000 BTU's output of heat.What size room will a 1500 watt heater heat?
A 1,500 watt heater producing 5,100 BTUs can heat 150 square feet. That's equivalent to a 10-by-15 foot room, an 11-by-14 or one sized to 12-by-12 1/2 feet with a standard 8-foot ceiling.How many 240v baseboard heaters can I put on one circuit?
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.How many amps is 10 watts?

Is it cheaper to heat with propane or electricity?
In most cases, however, propane is consistently cheaper than electricity because it burns hotter and more efficiently. This means less of it is required to heat your home. 98% of propane is manufactured domestically, which means prices aren't affected by international events as they are with oil.How many BTU do I need per square foot?
To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.Are modern baseboard heaters more efficient?
They use a series of resistances to make some heat that it heats the air through convention, then the air will heat the whole room. New baseboard heaters can be more efficient at the passage of hot air. That's why the replacement of a new baseboard heater is not going to save you energy.What size breaker do I need for a 15 amp motor?
