Product Overview

CNS-E convection heaters are an attractive and effective wall-mounted solution to heat a room. The modern European, slim-line design provides easy, flexible installation for new construction, or as a space-saving alternative for traditional baseboard heaters. CNS-E heaters have no fan, and their natural convection provides draft-free operation. The built-in thermostat has a selectable temperature range from 41°F to 86°F, and will work with an existing wall-mounted thermostat. A single CNS-E can be used as the heat source for a small bathroom or other room. Multiple CNS-E units can be placed strategically in larger spaces and their temperature settings adjusted individually for maximum comfort. CNS-E heaters range in size from 500-Watt to 2400-Watt, and in both 120-Volt and 240/208-Volt models.

Customer Questions & Answers

do room sizes for this 2400 watt one and the 2000 watt size differ?

The details and specs say both wall-mount heaters are for a room size 350-500 sqft., but since this one is much bigger, I think this is an error -- what does the manufacturer say? Thanks!
Asked by: Bea
The larger wattage heater will heat a larger room. Using the rule of thumb 10W per sq ft, the room sizes would be 240 and 200 sq ft. Allowance has to be made for ceiling height, and amount of insulation in the walls, ceiling floors. Another rule of thumb is 1W per cubic foot, which factors in ceiling height. Also outside temperature is a factor, so the quoted room size is only a guideline for typical conditions..

If there was a power outage would this unit come back on and continue to run without resetting a switch or something and return to it's original heat setting? I plan to use it for supplemental heat in a small cabin to keep the water pipes from freezing when I am not at the cabin. Thanks

CNS 240-2 E 2400-Watt 240V Wall-Mounted Convection Heater is rated 3.5 out of 5 by 2.
Rated 3 out of 5 by from Loud, loud and loud Easy to install, must be hard wired. When heating up and cooling down the thing clicks, pops, groans, pops again and it just keeps happening. Great heater for a loud environment, not a great heater for a bedroom.
