Hi!!!

The size of the door heater has nothing to do with the Room size as such.

Does the door has Four sided frame ( i.e. heater even at the threshold- which it should be!) or Three sided frame.?

Basically the heater length is
2 x h + 2 x w of the door. But since the heater shall be slightly more in length than these calculation, as the clear opening Plus frame size for the door heater.

Basically, you should get parallel heater so there are no issues on exact length etc.

YOu cut as per the requirement. Expcet you may have to check for the Heater diamter as the frame shall have a groove for passing this heater &that shall be deciding factor.

Which make is the door?

Hi thanks for your reply,
the freezer has a sliding door, and that is a four sided frame, total perimeter around the door is 6 metres long, and which has a groove to conceal the heater, but the supplier ask me what is the size of the heater I need, for example, 100 watts, 200 watts in 6 metre, so can you tell me what the power of the heater I need?
I am looking forward to hear from you.
Thanks

Generally you shall need 18 W / rmt heater & Total 6 mt long ( 18 x 6 watt). But we have used upto 24 watts / rmt heater as well.
