# Quick Answer: What Size Baseboard Heater Do I Need?

## How do I calculate what size electric baseboard heater I need?

A very simple method for determining how much total heating wattage you need can be found by calculating the square footage of the room, then multiplying this by 10 watts to produce a baseline wattage requirement. For example, if you are heating a 12-foot x 12-foot bedroom, it will have 144 square feet.

## What size room will a 1500 watt heater heat?

As a rule of thumb, you’ll need roughly 10 watts of heating power for every square foot of floor area in the room. This means that a 1,500-watt heater can be the primary heat source for an area measuring up to 150 square feet.

## How big of a baseboard do I need?

Here is a great rule of thumb: A standard 8-foot wall typically has a baseboard 3 to 5 inches tall, while a 10-foot ceiling calls for 5 to 7 inches. As a designer, I love adding height for drama. And the taller baseboards create a modern yet elegant finished look.

## 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 do I calculate what size heater I need?

What Size Heater

1. Multiply the length times the width times the height to calculate the volume in cubic feet.
2. Multiply the room’s cubic footage by 4 if its walls contain fewer than 3 inches of insulation.

## How much does it cost to run a 1500 watt heater for 24 hours?

A common wattage for space heaters is 1,500 watts. Apply the formula 1,500 x 24 ÷ 1,000 x \$0.20 to determine the cost to run the space heater for a day. (Dividing by 1,000 changes watt hours to kilowatt hours.) In this case, it will cost \$7.20 if it was running for 24 hours straight.

## Do all 1500 watt heaters put out the same amount of heat?

An electric space heater rated at 1,500 watts will put out the same amount of heat regardless what you pay for it. If you do use a space heater, be sure to: • Keep the heater at least 3 feet from flammable items such as curtains and furniture.

## How many square feet will a 5000 watt electric heater heat?

A 1500 watt space heater can heat an area of 150 square feet, and a 5000 watt garage heater can comfortably heat an area of 400 square feet.

## How many feet of baseboard do I need per room?

For what its worth (I.E., nothing) my initial ballpark guess for residential 3/4″ fin tube baseboard heating is that for every 18 square feet of indoor floor space that a room in the average home has it requires 1 linear foot of hot water fin tube baseboard.

## Are new baseboard heaters more efficient?

All electric heaters are 100% efficient at converting electricity to heat, regardless of how old they are, so replacing old baseboards with newer ones won’t save you any energy.

## What is the difference between 2kW and 3kW heater?

The 2kW and 3kW under-sink models have capacities of 10 and 15 litres, while the 3kW over-sink units are available with capacities of 10, 15 and 30 litres. (Note: These capacities refer to the volume of cold water each unit holds; the volume of hot water delivered may be slightly less.)

## Do oil filled heaters use a lot of electricity?

An oil heater’s radiator-like construction maximizes heat exchange with the air. Of course, the oil also radiates heat, but it does so at a slower rate. The heating element consumes as much electricity as that of any resistive heater when it’s on, but thanks to the heat sink created by the oil, that isn’t all the time.
