The unit delivers on its promises according to its specifications (in our case, it only operates for heating two units). The units heat an 80 square meter space in a house with significant heat loss located in the mountains. With an external temperature of 5 degrees and an internal temperature of 15, the space reaches 20 degrees in one hour.
Similarly, two other units in two bedrooms, each measuring 20 square meters, reach 20 degrees in one hour under the same conditions (5 degrees external and 15 degrees internal).
Tip: Show particular caution with the Greek controls of the unit. Express your caution from the beginning with the Greek controls (which, however, have half the price of the genuine ones), in case malfunctions or damages are observed (they replaced them for us, but some units remained out of operation for several days in the cold).

Ideal for large spaces. In just a few minutes (10-15), it raises the temperature by 7-8 degrees easily.
