Is anyone familiar with Berko heaters inside the wall? This property was built 32 years ago and on the wall are 6 thermostats that control certain type of heaters inside the wall. The thermostats read 22 amps for 240 and another amps for 277. The electric system is a single phase 120/240. Resident claims that it is very good system and in few minutes the walls get warm. Any input appreciated.
