No! Mysa is specifically rated to handle up to 3800W. If you exceed this limit there is a risk of electrical issues, device failure, or even fire. So please do not exceed 3800W. If you’re not sure what your heating system is rated for, here’s a blog that explains how to measure your wattage.
Are you ever going to put out a thermostat that can handle 4000W or more?
It’s not currently in our plans. The vast majority of electric heat systems installed domestically are under our 3800W limit.
