Is this watts per hour or is there a time scale to validate to this equation?

Watts lost per what timewise?

[@chrismartin5456]

Can I ask what the difference is between theoretical and actual u values?

[@ss6296]

Thans for information but u dont clear that in how much time it takes for this energy loss

[@farhanwicaksono9374]

[@simonsolberg]

very good. =)

[@danielmogos8990]

Man, why the hack doesnt anyone mention the time? In what amount of time will 1120watts be lost? In one hour? one day? one month? Really, when doing this formula didnt crossed your mind that you need time to actually measure heat loss? REALLY?

Here in the US we like to use Fahrenheit Celsius really don't tell us anything
