This is the Panasonic Etherea CS-E7NKEW reverse cycle heat pump. The indoor unit is a stylish wall mounted model and comes complete with a handheld remote controller. The CS-E7NKEW is the smallest model in the range in terms of output capacity; see the data table below for full details. This type of technology efficiently heats and cools the requited living space and because it is independent from the rest of the house heating, is ideal to heat an area whilst leaving the main heating system off. The indoor wall mounted unit uses intelligent electronics to constantly alter its running mode, to ensure these systems always run at the most economical level possible.
