Use this handy chart to estimate the wattage of the heater(s) you will need to comfortably warm your area.
Each type of heater has its own advantages. Review this chart to see which choice is best for you.
|TIME TO HEAT||Wall heaters use fans to push heat into the room very quickly
Baseboard heaters generally require 30 to 60 minutes to heat a room
|WALL SPACE REQUIRED||Wall heaters use less wall space
Baseboard heaters tend to use more wall space
|NOISE||Wall heaters are generally quieter than a regular refrigerator
Baseboard heaters are virtually noise-free; good choice for bedrooms
|TEMPERATURES||Wall heaters operate at higher temperatures than baseboard heaters
Baseboard heaters operate at lower temperatures, which means their surfaces are cooler to the touch than the surface of wall heaters.
|Lifespan||Wall heaters will typically last 8 to 12 years
Baseboard heaters often have a life more than 20 years
First, find the wattage and voltage of the baseboard heater you’re replacing. You can find this information on the identification label of the heater. If the label is missing, you can determine watt by measuring the length of the baseboard (most baseboards are approximately 200 – 250 watts per foot), then use the information on the electrical panel board to determine the voltage of the heater.
For help selecting the right wattage for a room, please see our Heat Selection Guide. Installing a lower wattage heater will not cause a problem on the circuit, but if it does not supply enough wattage to heat the room, the heater may run continuously in an effort to bring the room temperature to the temperature set on the thermostat.
However, increasing the wattage may cause a problem if your electrical panel board (circuit breaker or fuse box) and supply wiring is not equipped to handle a higher load. All electrical work and materials must comply with the National Electric Code (NEC), the Occupational Safety and Health Act (OSHA), and all state and local codes.
