Many homeowners wonder how they can calculate the current total wattage of their baseboard heaters in each room. If you’re thinking about purchasing Mysa Smart Thermostats for your home, you should know there’s a limit: Mysa can handle up to 3,800W. This is around the standard for any high voltage thermostat. We strongly recommend you do not exceed this wattage.

But now you’re asking:

“By golly, how do I know if I’m over the limit?”

Well, there’s a couple of ways to check:

 

Method One

The easiest and simplest way to calculate the total wattage of your current baseboard heaters is to locate the manufacturer’s label on your heaters. The wattage is often listed on a sticker. If the wattage is not listed on the label, you can determine the wattage of each heater with this simple formula:

If you get the information directly from a sticker on the heater, it should be an exact figure and not an estimate.

 

 

 

Method Two

If you are unable to read or locate the manufacturer’s label, then you can estimate the wattage for each baseboard by measuring the length. As a general rule, you can approximate the heater’s wattage by using the following calculation:

However, remember that this is an estimate. If your calculations come anywhere close to the 3,800W limit, please consult a professional to make sure that Mysa is compatible.

 

 

 

 

Multiple Heaters

Remember that your total wattage must include every heater attached to a single thermostat. To calculate this, simply calculate the wattage of each heater and add them all together.

If you’re anywhere under 3,800W it’s about time you Meet Mysa!
