What circuit does the CNS 300-2 Plus need?

It runs on 240 V at 12.5 A and needs a dedicated 15 A circuit with 14 AWG copper wire. Plan on a hardwired install, not a standard outlet.

How much space will 3000 W heat?

At 10,236 BTU/hr it suits a small room or bathroom, roughly 100–150 sq ft in a well-insulated home. Larger or drafty rooms will need more than one unit.

Does it have a thermostat and frost setting?

Yes. The built-in thermostat adjusts from 41 °F to 86 °F, and a frost-protection setting holds about 45 °F.

Is it safe to leave on unattended?

It has automatic shut-off and is designed for continuous wall-mounted use. Keep furniture and curtains clear of the surface, which gets hot.

Is $269 at Amazon a good price?

That is the best new price across the two stores listing it as of November 5, 2026. Check the price history to see whether it has sold lower.
