Do I need an electrician to install a wall heater?

For 240V models, yes — an electrician should run the circuit and ensure proper wiring. For 120V models, a handy homeowner can often handle installation if an existing outlet is nearby. Always follow local building codes, and when in doubt, hire a professional.

Can a wall heater be my only heat source?

For small rooms (under 150 sq ft) like bathrooms, a wall heater can be the sole heat source. For larger rooms, they work best as supplemental heat alongside central heating. In mild climates, higher-wattage wall heaters can serve as primary heat for individual rooms.
